Hello, for my new car ( Subaru BRZ 2015 series blue) i want to replace original headunit from Subaru with something better. I looked at marked, and only Parrot RNB 6 was up to the task, but it was only demo, no units will be sold.
So i started to search tablet/phone, that could be converted to headunit, most important, it must be fast, high quality large display, no buttons, drilling or anything on touchscreen, and so on. I was unable to find anythink that will fit inside 20x10cm space ( yes, nexus 7 would be good, but i don't like this device for some reason)

So i get Nvidia Shield 16GB wifi model. Now i have a lot of skills in analog and digital electronics ( apart from usb/lan and other high level communication), so i want to get few ideas how to create/mimic original headunit features. i will name each with number, and if some one has good idea how to do it, please attach the number to message, to keep it simple.
1) Turn on with ignition and turn off with engine as normal head units do. I think i will add much larger battery keep it alive, and use MCU for voltage monitoring, so it will disable battery if it discharge main battery too much. like 13V cutoff.
2) Ability to connect to phone via blue-tooth, so it will use it's own speakers and mic for conversation. usual headunit functionality. I will connect mic to car original microphone location, same for speakers.
3) better audio, i will use original stereo speakers or microphone jack in order to get sound. I will do amplification myself. I will try to make my won audio dsp, that will handle some effects, and create small delay from original signal into back speakers, for 3D sound effect.
4) Use cameras as video registrator and backup cameras. Car does have reverse signal , so it will be nice to integrate it somehow, also will try to play with USB video class cameras, that could be used as video registration,just will it record in background and do video loop ? Or just delete original file after travel and use 32/64gb card.
5) motion based video/pictures capture, since Nvidia Shield does have multi-axis accelerometer it would be nice to capture images video when car is parked, and moved, this would be so nice to have
6) does any one have other simple ideas? Remember, i am good with power electronics, micro controllers ( high end ones, no arduino for me, too slow), audio dsp processors and so one.

If you mean trying to turn the shield into what looks like a BT headset, my understanding is that this is POSSIBLE, but that it's a huge amount of work.
I think it's Qualcomm that has code for this, so it might be feasible mostly on Qualcomm BT/combo chips. The effort required seems to be akin to creating your own ROM. I think somebody, somewhere, may have done this once on some device.
I think your biggest need is software, lots and lots of software, requiring lots of work and tweaking to get exactly what you want.
Who is going to build and maintain this software ?
Best chances are with devices that are VERY popular, like Nexus 7 2013 (and yet I think nobody has ever turned an N7 into a BT headset equivalent), And 2013 is 2 years ago and Google no longer sells it (but $150 new on Amazon etc.)
More obscure devices have little chance of finding developers when MUCH more popular devices have found few devs.
Frankly I think you are much better off using one of the CarJoying.com , etc headunits. There is more than just an android tablet to them. There is quite a bit of additional hardware, and even a separate micro-controller running a whole bunch of firmware at a very low level, to tie it all together.
For the cost of these headunits ($200-$300) its not worth it at all to try to build your own, and whatever you have will never be as functional using a regular tablet as the base.
It would be nice to use tablet, because hardware usually is at lest one order of magnitude better than any car head unit. Display is full HD, not 800x480, also, it is larger, and is around 20cmx12cm ( so i will have to create my own front panel to mount it, but i think i can do a good job too)
Lookup Nvidia Shield tablet specifications, can you find any headunit, at least 2x less powerful ? No, you can't !
Processor NVIDIA® Tegra® K1 192 core Kepler GPU 2.2 GHz ARM Cortex A15 CPU with 2GB RAM
Display 8-inch 1920x1200 multi-touch Full HD display
Audio Front facing stereo speakers, dual bass reflex port with built-in microphone
Wireless 802.11n 2x2 Mimo 2.4 GHz and 5 GHz Wi-Fi Bluetooth 4.0 LE GPS / GLONASS
Regarding power up/down, it looks like i could use original feature, to keep LCD alive if charging is plugged, just question how to clear all programs, so it would consume as little power as possible ?

The 1024x600 screen is more then enough for an in dash. I'm VERY pleased with mine, I even bought a Nexus 7 with the same thoughts as you but to get even half the functionality that my CarJoying head unit has would have taken years. It's also got the quad core processor and is very quick, in fact it works better then my Nexus 7 does since Lollipop killed my 7.

It's not about power, it's about integration. I have 3 Shield LTE tabs in my household, along with a car audio install that I'm gearing up to compete in MECA's ModEx sound quality class next season.
I tried the Shield route. I wanted it to work, I really did. There were just too many small issues that added up to an overall big headache... The OTG integration just isn't there, for one. The Joycon for the steering wheel controls is, well, not the best. I was constantly having to unplug / replug the OTG cable to get an external drive and outboard DAC to recognize. EasyCap for the backup camera is kludgey at best. And, let's face it, it takes forever to boot up and running the thing sans battery with a direct wire connection is still an amperage hog even in standby.
I ran the Pioneer AppRadio 3 with AppRadio Unchained to get full Android access with an RK3288 HDMI stick for awhile, then upgraded to the Pioneer 8100 NEX with the same stick, but the occasional bluetooth hang preventing me from having touchscreen access on both decks wasn't cutting it.
I now use the Newsmy NU3001 and couldn't be happier. The display is perfect for the car, for competition I use an HDMI audio splitter to feed optical to my DSP to play FLAC files. If I need to play a CD, I have an Alpine changer with optical out also going into my DSP.
All I can tell you is good luck. I hope you have more patience than I did.
I understand, that for some users that will be hard to do.
my basic needs are very easy to integrate, navigation/music/power_up/power_down. This is very easy to manage with additional microcontroller ( and i am good at that), that takes control over volume buttons, power button, and i can do power management based on do i get power from car, and if yes, what is voltage on car's battery, so i could do intelligent decision will i keep tablet in standby ( locked screen) mode, or i should disconnect power all together to drain no power at all.
By looking at screen back light, and voltage levels on connection to the car, i can lock or unlock device, so this take care of basic functionality, i will also add few capacitive buttons for volume control on panel itself. And i know that were is a program, that will pause audio, if some one press power button, so i get last bit of functionality i need.
Car does not have any volume or other buttons on the steering wheel or anything, and original head unit from Subaru BRZ only could manage calls, sms messages from phone, and play music, and do navigations. So i can reproduce at least 75% of original head unit functionality simply by using 12V-> 5V USB charger. Original amplifier is in the back on th car, so i can use speakers output as my main audio. That it !
hi, I have a 2012 Chrysler Town & Country with the touchscreen stereo but it does not have navigation. I was thinking to get one that has navigation but I'm not impressed with the features from the OEM stereo.
I have searched and cannot find any head unit that is specific to this vehicle. Does anyone know what it would take to install a universal android head unit in my Town & Country?
My vehicle has the steering wheel control and the CAN bus.
I really like the one from InDashNet.
Thanks in advance.
I've attached a few pictures of my current stereo connectors.
not sure about the universal, but I think that Chrysler used the same radio in Chrysler family (Chrysler, Jeep, Dodge) for that time frame.
you will probably need to look at your specific radio and see if it looks like one of these Jeep ones, whereas they look the same, but they mount slightly different:

I have this Joying for my Jeep and love it:

CadillacMike, Thanks for the reply.
Did that just fit into your Jeep, or did you have to splice any wires?
For my Jeep it was plug and play, and works like a champ. This is the harness that comes with the Joying. That purple looking box is the Canbus adapter that should keep your steering wheel controls working

The gray module on the Joying clips right into the Jeep wiring harness
I also sold my old 430N for a decent price on eBay.
However, it is worth noting that I had the Jeep with the base audio system.
Got the same Joying for my buddy with a Jeep that had the premium alpine factory upgrade, and his amp and sub do not work right. So we are having to get a PAC module and splice a harness together.
However my Jeep with an aftermarket sub and amp works just fine. looks stock
Ok, what year and model is your jeep? And you had the 430N huh?
My T&C has the 430, so I know a 430N would just plug and play right in. I've spoke with a dealer parts dept who said that the 430N from a jeep should be the same as from my T&C.

mine is a 2016 Jeep Wrangler Unlimited. However they haven't changed the dash on Jeep since 2011.
I dont know for sure, but I have read that Jeep combines the Sirius and GPS cord into one. So in theory Chrysler could do the same, and you would have a GPS antenna already available.
The Joying does come with its own GPS antenna, but i bought an adapter on Amazon for about $10 that allowed me to reuse my existing Jeep GPS
Ok, sounds like I'm willing to give it a shot.
Just a little info on the Joying you bought. I see it had only 1Ggb ram. On a phone that usually causes serious lag. Have you noticed any on this stereo? Any cons at all that you know of?
Well you have to set your expectations accordingly. Some people on these sites complain about these radios like they expect since it is Android it should be the same as a 2016 Flagship phone.
I have a Samsung Galaxy S7 Edge. It is awesome. I do not expect an under $400 chinese radio to perform the same.
I got mine from Amazon with Prime:
https://smile.amazon.com/Challenger...F8&qid=1471449612&sr=8-1&keywords=joying+jeep
Joying support is good, but it is in China, so massive time difference, so about 1 email per day back and forth. So just realize if you need to contact them, a small communication could take a week or so. They write back every day, but there a language barrier and a time delay.
So for me, my Joying is great. I have a remote start, and use that as I walk up, so I dont care about the 30 second startup.
At first it is super cool to have Android and you try a bunch of stuff. More stuff you do, more lag will occur. Now that I'm getting into a routine with it, it performs pretty good. But, I use it like a car head unit.
So I use it for music, GPS, and phone calls, which is about the same as I have used any previous car radio.
I dont use FM radio, I use Google Play Music, Pandora, and Spotify. GPM is a little slow, but works. Pandora works fine, but requires data, and I have plenty of data, but it is annoying to have to turn on and off my hotspot and turn wifi back on when needed. I have found Spotify works the best. I have a Premium account, so I save music offline to the sd card. The Spotify interface is car friendly and is pretty fluid, and it easily recognizes the external sd card, which GPM did not.
GPS i have tried several, but currently sorting through 4. Google Maps is great, but again, kind of laggy like Google Play Music. Neither are intolerable, but just not as fluid as their counterparts. Waze works great with data, but without data it is not as good as a regular offline GPS, and it can be a little slower. Here WeGo (formerly Here Maps) is pretty quick, and looks good. Joying gives you a copy of iGo, and it is hands down the most fluid and works the fastest. At first i didn't like the Interface of iGo, but now it is growing on me, and i tend to use it the most.
Calls you have to use the built in Bluetooth. It works fine, I can hear people fine, and they can hear me fine. The only caveat is for some reason it routes all the audio to one speaker, the front passenger. So I can hear people fine, but they only come out of one speaker and have a mono sound. I have not had any complaints about how I sound when I use the Joying provided external microphone.
The only extra thing I use is a calendar app. That way it syncs with my phone calendar and I can use the location field to link to GPS. So if I have an appointment at the doctor. I pull up my calendar, click the location and it goes right to Google Maps to guide me there.
I love mine, best car radio I have ever had. However, I did research these for a year, and I more or less knew what I was getting into.
I only plan to use GPS, and a music player, and occasionally FM stereo. So, I'm ok with not having a flagship phone. I also like to connect via Bluetooth for incoming alerts and such. Do you know if you receive incoming alerts when you are listening to music? For instance, with my 430 factory stereo, if I am connected via Bluetooth but listening to music from the HDD and I get an email or whatever, nothing comes across the stereo. I have to switch from HDD to AUX in order for anything to come from the phone to the stereo. That, to me, is junk.
One more question, I think, on this Joying unit. About the display. It's only 800x480 resolution. Does that cause any problems? I've read some places where even Google Maps doesn't display very well with that resolution. What is your experience?

I would think not. I am not sure any of my vehicles do that. Although I do leave my phone on vibrate 100% of the time. Most cars will give you phone calls or SMS, but I dont know that I got an alert for email or anything from my Cadillac, 300, or Jeep?
The Joying does NOT do SMS. All you get is phone calls. It will ring and the name/number shows up on the screen. You can access your full phone book. But you do not get any access to text messages.

I too was worried about those specs when reading all about these, but mine looks fine. The Malaysk ROM on here makes the DPI different or something to make it look better, but either way was fine. Those specs wouldn't work for a 55 inch tv, but it is fine for a 6.2 inch screen
A picture of a screen doesn't translate well, but you get the general idea:
Google Maps
Waze
Spotify
Pandora
Looks good enough for me.
Thank you for all your input. I think I'm gonna get one and see if it works in my T&C.

I want to thank you both for posting this. I have a 15 T&C with the 430, and have never liked it. I have been looking at these Android Head units since I got it. Lepricon please let me know how it works for you. I especially want to know if it runs the kids TV in the back ok. Thanks again.

My jeep doesn't have a video system in the back, but I have read a lot about these units.
Rear TV should work, but only for the DVD player i think. I dont think you can fire up Netflix on the Joying and have it show on the TV in the back

I should be getting mine tomorrow. If it's just plug and play then I expect I'll have it installed and working by afternoon.
I don't use the video player at all, so I won't be much help there. But I'll let you know about pretty well everything else.
Mike,
Got my unit in today. Thank you for the recommendation. So far I really like it. With the bezel installed it looks factory. I'll try to get a picture uploaded tomorrow. Really looks good though.
Install went ok. I mean, I get sound and the steering wheel controls work. There are 2 connectors on the harness and 3 on my van. However, only only one of the connectors from the van matched up to the stereo. So not sure what's going on as all 3 from the van were plugged into the 430. Also, I got the antenna to plug in, but there is another plug that looks the same and has no where to plug into the stereo. I assume it is the one for the serius radio.
But, everything seems to work, except the backup camera so I assume it's one of those connectors that didn't fit.
I've emailed Joying, just waiting for a response.
Update:
Joying says that their head units do not support the factory backup camera. They say I have to install their camera.
For now I'm gonna look for the wiring diagram to see if I can just splice into the camera wire. If not I'll be returning the unit. The backup camera was the main feature I was looking for when I bought the van.
you would have to post some pics. My camera works great, but mine is aftermarket. My Jeep had 2 gray plugs, one white, and one yellow.
Big gray was the wiring harness, should connect to Joying
little gray was Uconnect, not used with Joying
White is the radio antenna - should connect to Joying
Yellow is combo GPS and Sirius. you can't use Sirius, but I bought an adapter to make my GPS from Jeep work. You could always use Joying's GPS as well, I just figured the Jeep one would be better.
I had the Brandmotion aftermarket backup camera. It plugged into the 430N with one of the large gray plugs, but I could disconnect the large gray part and there was a regular RCA left and it plugged into the Joying and works great. Not sure how the factory works though

Thanks for the update. I saw some other posts talking about the the backup camera I think, but it was months ago. If I find them again I will update you. Would love to see the pics.

I hope that helps
Ok, I just ordered this adapter
http://www.crutchfield.com/S-C3LLCFgVJvD/p_120CHRYSAV/Metra-CHRYSAV.html
I spoke with the manufacturer, Metra, and they assured me it will give me my stock backup camera back. I should have it by Thursday so I'll let y'all know if it works.
Cadillac Mike, what adapter did you get that lets you use the jeep gps/serius antenna with the Joying unit?
I just received this unit:

Summary in case the link dies, it is a 2013/14/15 Altima specific radio, but the underlying hardware seems fairly generic. Similar units are available for a number of different car makes and models.
If you are considering an Android head unit for your car, you must first read these links.
https://forum.xda-developers.com/wiki/Generic_Android_Head_Unit/MCU_Explained
Note that the links below go back to head unit designs that were available a few years ago and much of the comments and problems do not apply to current hardware.
https://forum.xda-developers.com/wiki/Hui_Fei_Type
and
https://forum.xda-developers.com/showthread.php?t=2660662
I like that it has a full 8" screen but also has buttons and knobs which integrate very well with the car's dash and make use in a car much easier and safer (touchscreen-only controls in a car is a safety hazard).
The price was very attractive and I was able to separately buy a PX5 core board (4GB/32GB) for ~$100 (not received yet) so I will have options in case the PX3 CPU is too slow.
The unit appears well made. I have been running it on the bench for about a day and most everything I tried seems to work as expected (caveats below).
The LCD is good, with very wide viewing angle (one of my concerns), the resolution adequate (interestingly, the 1000x600 screen is much better than the pokey 480pixel units on the $600 Pioneer unit I checked at Best Buy), the touch screen is very responsive.
One strange issue is that it takes A LONG TIME to download anything. The web browser (Chrome) works well, but downloading apps from the Play Store takes forever, even though if you are patient, they eventually complete. I have read in another thread that it may be due to insufficient cache space. Whatever the cause, it is irritating, but it is not something you do too often (aside from initial setup,) so it's not a deal breaker. I will report if the PX5 coreboard improves on that when I get it.
Aside from the downloading slowdowns, the unit seems to handle multitasking properly. I was concerned about the Px3/2GB RAM set being underpowered (which is why I bought the PX5 coreboard) but it seems quite usable as is. I suspect that earlier units with 1GB RAM do not fare as well.
Now some random observations:
The radio app works but the UI could use improvements. There does not seem to be a way to name the stations once they are memorized. They take the name of whatever is streaming out of the RDS system, so most stations I saved are named from the song they were playing at the time...
Navigation uses the iGo app with naviextras.com maps. The maps appear to be several years old. There is a particular issue in my street that has been fixed just about everywhere (Google maps and the various GPS nav units I have had my hands on) at least 3 years ago but it is still there on these maps. Not sure how to upgrade the maps since the radio is not registered on the naviextras.com web site. I have placed a question in the customer service area of their web site. They want a zipped copy of the license folder. I have found the folder but not managed to do that yet.
The music player is also adequate. I have not found how to transfer music from the thumb drive to the radio itself using the stock FileBrowser app . That will probably require a separate file manager app of some sort. There is an equalizer with separate sub setting. Interestingly, I have been using the radio with a set of inexpensive Harman Kardon computer speakers (using the RCA output connectors, not the speaker outputs) and the sound is pretty great with the equalizer set to flat. The noise level is extremely low (I am using a well regulated power supply, I will update once the radio is in the car with engine running.)
The radio does not shut down when "powered down", it just goes to sleep. Current consumption in sleep mode is very low (I measured 15mA.) I turned it off last night before going to bed, expecting it would take the ~20 seconds to boot this morning. To my surprise, the radio turned on as soon as I pressed the power button. This is even faster than my Altima's OEM radio! A pleasant surprise.
I bought the radio with a separate Bluetooth ODB scanner from the same vendor as it is advertised as supporting it. The Torque app is installed in the radio, so it seems it is ready to go (I have seen some older Android head units that could not access Bluetooth OBD dongles.) I have not tried it yet.
I connected the radio to my Android phone via Bluetooth last night but did not do anything else then. This morning, while eating breakfast with the radio playing music, the phone rings in the radio and I heard a voice mail from DHL advising me of the impending delivery of the coreboard. So I guess the phone link works too Interestingly the phone was a good distance from the radio (I have a big house) so Bluetooth range is plenty, much more than adequate.
I was reluctant to log into the radio with my main Google account (since it would be easy for anyone breaking into the car to have access to all my Google information, stored passwords and such, so I created a second account with simply the few phone numbers I am likely to want to call from the car and used that to log into the radio.
I have not been able to place a call directly from the radio via voice command or otherwise. I was able to make it read my phonebook from the Android 5.1 handset, so when I ask the radio to call my wife, it properly finds the number and it displays a green handset saying it is calling, but nothing is happening on the phone. A problem that I need to resolve before putting the radio in the car. Note: I also have a Bluetooth headset for my motorcycle helmet and I have no issue calling any number of the phonebook through that, so the issue is not with the phone.
When a call comes in, the phone app opens up and everything works pretty much as expected. Sound is pretty good on both ends. However, the phone app has a row of buttons at the bottom of the screen and some are semi-transparent while others are opaque, so depending on what app was running, those semi-transparent buttons are not legible. This is very strange. When the call was over, the radio which was running did not turn back on (but when I got the voice mail from DHL earlier, the radio turned back on after the call.)
Overall I am quite pleased. I have a couple of bugs to fix before I install the radio in the car. I will report then how that went.
Edit: The MCU version in that unit is MTCE_KGL_V2.70_2, Oct 22 2017
Update:
Attempted to install the head unit in my car today. Removing the trim parts, swapping the bracket between the old radio and the new one was fairly easy. The mechanical parts match well with the mounting holes and the look of the head unit matches the rest of the dash very well.
There are two small connectors that were plugged into the old unit that do not have a match with the harness that came with the new head unit. I suspect it is the XM antenna and the USB socket, so I plugged the connectors that did have a match to the harness, reinstalled the radio temporarily and turned it on.
The unit came up but no sound.
The small LCD display at the center of the dash (between speedo and tach) said "Audio is off" and indeed, nothing came from the speakers. I suspect the Bose amplifier is not getting the signal to turn ON. The cable harness that came with the head unit has an open wire labelled "AMP CON" going out (to the car's wiring) which I assume is for Amplifier Control that needs to be connected to 12V to turn the amplifier on. I need to try that.
All the steering wheel controls did work and operated as expected, so that was good news, but no audio is of course a bummer.
My car has the Bose audio system and I have read that these are not typically compatible with generic head units without some rewiring or an adapter, so unless I can find something on the internet in the next couple of days, I will take the car and the radio to the local installer and ask them if they can make it work. I am not sure what is the solution with the backup camera. I would really prefer to keep the original camera and I can't imagine it would be very hard to make it work. For now, it is back with the original audio system.
Here is more info about Bose audio systems: (can't post links so Google "understanding-factory-bose-system" which will point you to altimaforums dot net)
Edit: I found the blue connector that had no match on my harness goes to the USB socket and Crutchfield has an adapter (search for Metra-AX-NISUSB2-USB-Adapter-for-Nissan on the Crutchfield site, I can't post links yet). I called Crutchfield and they also do have an adapter for the Bose speakers, I ordered it with the USB adapter. They also said there is no solution to use the built-in camera, I will have to use an aftermarket one.
Edit2: Found out that the OEM backup camera is supported, the connections are there in the harness that came with the head unit, I just had to plug the right connectors together. So the only issue originally with the head unit as received was the Bose audio system support which should be fixed with the Crutchfield adapter, due next week.
Note: under the factory radio is a large white plastic box with a large multi-pin connector that has its own harness and does not seem to be directly connected or related to the head unit. It is mounted on the same bracket as the radio, so I reinstalled it in the car. I am curious what that box is for.
I received the PX5 coreboard (4GB RAM + 32GB Flash). It came with Android 6.0 compared to 7.1.2 on the PX3 board (which has 2GB RAM and 16GB Flash).
The PX5 board has a large heatsink over the CPU and memory while the PX3 board has the chips exposed. I would expect a higher current consumption.
Operation was very smooth, but since the PX3 board was already smooth, the change was just noticeable when switching from one to the other. The one major change is that downloading apps, while still not nearly as fast as it is on my phone, is considerably faster than on the PX3 board. Now it's just slow, compared to absolute molasse.
I did not time the boot time but there was no significant difference between the two, not enough to make a decision based on that. Both take 20-30 seconds and both restart immediately from sleep mode.
Android 6.0 definitely has more rough edges than 7.1.2. I particularly dislike the launcher which looks like this (this picture is not of my unit, but the same screen):
compared to the PX3 (Android 7.1.2) launcher:
I find it much easier to have the important icons at the bottom of the screen rather than on the side.
There are also fewer settings under Home->Settings.
I know I could reflash the Android version but right now, I put the PX3 coreboard back in the unit. I may keep the PX5 in case I would run out of Flash, but since the unit came with about 14GB available (out of 16), it is unlikely that I will run out (my music is on a flash card and there is also the USB port).
One observation: I have an old iPod 5th generation (the one with the 60GB hard drive, it is probably 10 years old) and neither unit recognizes it, so that is a little disappointing since it works very well as a portable music system and it works fine in the Altima's OEM head unit.
i also like that other launcher, my 7.1.2 unit didn't have that launcher
At the moment, I am looking at upgrading the Android version on the new coreboard but I will install the radio with the quad core PX3 this week end anyways.
Here are pictures of the installed unit and a little feedback after 4 months of ownership.
Short version: I love it!
Long version: I installed the radio in the car and found out there was no mechanical issue, the radio fit without having to pry or push anything and it looks great. The finish and texture of the facia and buttons perfectly matches that of the car. The only hint that this is not an OEM system is that it is way too nice
However, my car has a Bose audio system that needs to be turned on when the radio turns on and the Bose system has low level differential inputs. The radio has low level outputs on RCA connectors which do not directly interface with the differential inputs of the Bose system so I bought the audio cable adapter from Crutchfields (along with the USB cable adapter) and I took the car and radio to the local installer (I did not want to have to mess with) to have it installed the second time.
Of course, the "professional" installer connected the Bose system to the radio's speaker outputs so when I got the car, with the volume control in position 1, the level was enough for highway driving. In position 2, it was too loud. I can't believe they thought that would be OK. Anyhow, I took the car back and told them that was the reason I gave them the audio cable adapter. 2 hours later, the car was ready (again) and all is now good.
Everything is working (steering wheel controls, bluetooth, backup camera, USB connector, WiFi) and the audio sounds really great.
Navigation works well. I am not sure how I will be able to upgrade the maps. I asked the vendor and they sent me a link to a recent version of the map for the US. Not sure how long they will keep doing that. Of course, I can use the phone in hotspot mode and run Google Maps on the radio via the phone's 4G data connection, as long as there is 4G signal that is.
The nav application has the annoying habit of notifying me when I go more than 3 mph over the speed limit. It only does it once, until the speed limit changes or I turn in another street. I looked through the settings and I have not found how to turn that off. I guess one could consider that a useful reminder. In this area, most traffic goes about 15 miles over the limit so it is annoying.
I bought a Bluetooth OBD-II adapter and that works well with the Torque app to monitor engine and emission parameters.
I somehow expected the FM radio to be cheaply made and with average (or lower) performance. I am very glad to report that the FM radio works at least as well as the OEM radio. My favorite radio station is 50 miles away and with most cars, I do not get good reception everywhere in town, there are areas where the signal is barely there. This radio has not experienced a drop out yet in town. Not only that but the audio quality is actually excellent. The local public radio has outstanding sound quality and it definitely comes through on this set.
The only remaining irritation is the radio app itself. There is no way to set the name of the stations saved in memory. The radio automatically captures the RDS stream and uses the last 5 characters received as the name of the station in memory. I assume that Chinese FM radio stations only broadcast their name via RDS and it works for them. Over here (US), the RDS stream is also used to indicate the program currently playing, so the "name" of the stations in memory is useless.
The head unit came with a dual core/16GB CPU board and Android 7. I also bought a quad core/32GB CPU board but it comes with Android 6 and the launcher is not nearly as nice, so I kept the dual core card in the radio (I tried the FCC launcher and did not like it.) The dual core is fast enough, honestly the quad core was not noticeably faster and I believe 16GB will be enough since there are two micro SD sockets (one used by the maps) and two USB connectors for additional music or video storage.
Finally, a slight disappointment: my iPod will not work when plugged into the USB port. I have a lot of music on it (60GB device) but the radio apparently is limited to 32GB storage devices on USB.
Note that the screen protector is still on the LCD for the pictures above. The display is really good and usable in most conditions, unless the sun comes through the rear window directly on it, not a frequent occurrence.
Hi. Interested on your radio. Can you post the link where you bought that? Is there any way to make it to work with the stock reverse camera? Thanks
I have found how to disable the warning from the navigation system. It is much more pleasant now.
You have to go into the factory settings, password 126
Since the Altima was totaled last year, I kept the radio because it is so nice I was hoping I could find another Altima V6 to put it in, but I could not find a car I liked so I eventually bought an Acura TL therefore I just put the radio for sale on eBay.

It works with the Nissan camera, I just had to connect it, simple as that. I bought it on AliExpress, here is the same unit from somebody else:
https://www.aliexpress.com/item/32865581547.html?spm=a2g0o.productlist.0.0.3b353585OJGe9o
Note that you still need to buy the Bose and USB cables to connect to the Nissan harness.
I have been looking at getting a wondefoo android head unit for my Toyota Sienna. It looks like it has good specs (PX5 chipset, 4gb ram, 32gb storage) and the seller has quite a big selection of HU's on aliexpress for different cars but I can't find that many reviews of wondefoo units as compared to xtrons or seicane. Have any of you tried one of their units before and if so how was it?
I'm also looking at one. I know that this one: https://www.aliexpress.com/item/IPS...pm=a2g0s.13010208.99999999.280.2f743c0098GCRV is MTCD based.

I have this one from youmecity on aliexpress and find it to be superior in every way.. My previous one, the one that you are looking at, did not really have Android 8, it was Android 6, hacked to appear as 8. This one is also cheaper and ships free. Got mine in less than a week. Also their customer service is outstanding - they respond same day . I have had several of these Asian units and this is the first one that has been trouble free and is really acceptable, to me.
It also supports an external USB HD of up to 500MB. I have a Samsung 500GB SSD behind the dash and it works fine. I have no complaints and it has been in use since 1-1-2018.
thanks for the reply cardio77.
I was hoping for a unit with volume and tuning knobs, as my Rav4 doesn't have steering wheel controls for the audio. I was also hoping to go with a PX5 SoC as opposed the All Winner.
The hacking to make Android 6 appear as Android 8 is quite worrying though...

You could install malaysk rom on that system because it has an sd card slot, which should definitely get you android 8 as far as I know All the systems for the Sienna don't have a sd card slot so unless theres a way to install malaysk rom with usb or an adapter I'm gonna be stuck with the factory firmware.
I have ordered one of these with 4GB RAM and 16GB flash. I will keep everyone posted after it shows up.

My head unit showed up yesterday, and I opened it today. It looks to be of reasonable quality, other than the word phone being misspelled on the button (lol). However, I've taken a look at the pinouts listed on the sticker on the top of the unit, and it appears the wiring harness is missing the wires for Canbus. Am I correct to assume that these would be the wires for steering wheel audio controls? I don't have them in my car, but I was considering adding one of the aftermarket ones.
Here's a link to photo with of the back of harness, front of the harness and pinouts on the unit:
back of harness
front of harness

Is there a way I could wire them up myself?
I have one in my Alfa Romeo 159 with Malaysk 8.0 Rom installed. All ok, working pretty good.
Ah, I've realized that steering wheel remotes use the Key1 and Key2 lines. What's the best way to tap into these the wires in the harness?
Does anybody know where I should tap into wires for the following connections? They are on my harness, but I'm not sure where to connect them:
Amp-con - amplifier control
Ant
Tv-ir = ?
Back-car - reverse signal
Auto-ant - auto antenna power
Brake-ctl - hand break signal
Not a great start with this unit so far. I can't seem to enable WiFi on it, and when I look in the advanced network settings, the MAC address looks like it doesn't have a WiFi adapter at all.

I now have 2 of them and no problems with wifi at all. The WiFi setting is on the home screen of both of mine, as is bluetooth. Settings can also be pulled down from the top of the screen just like any android phone. WiFi reception is much better than on my previous Joying HU. It is not 802.11 AC but 30~ 40 MBPS from about 60 feet from my access point in the house. I also found that you can use an ethernet to USB adapter for much faster results for downloading software and updates. I just run a cable out the door into the car and I get 400 MBPS +.

the Bluetooth isn't working either. I suspect I've gotten defective unit. I'm following up with the seller.

Yeah, I had no trouble finding the setting to turn wifi on, but it won't turn on when I tap on the button. I suspect the wifi and Bluetooth are defective.

The seller says the wifi board (chip?) maybe unseated and is going to send me a video showing how to reset it. I hope that this is the problem and I can fix it.

Well, I finally got a chance to get the head unit out of my car today to try to reseat the board, and it appears to have worked. I'm surprised because it really didn't feel out of place at all, but it seems to be working fine now.
well, the Wifi failed again, so I tried the same thing, and it now appears that the screen is messed up. I've done a quick check of the ribbon cables connecting the screen to boards, and nothing seems out of place. Here's a photo of the screen now

Any idea how what I might have done?
DO NOT TRUST THIS SELLER. It looks like a frauder. I paid a navigation and after 1 mount the item is not even shipped. Now i am trying to get my moeny back.
Hey guys!
Been looking at a lot of android units, but have narrowed it down to two, one being a Wondefoo. The listing says the mic won't work with 'OK Google' etc. only for Bluetooth. Can anyone confirm? Is this the case with all android units?
Thanks in advance.
Hello, which brand would you recommend ? I've been reading topics here and narrowed it down to maybe those two. It is for Opel Insignia 2008 . I browsed some "tesla" style with the bigger screen which replaces my whole front panel of the cd which controls the partonic and has sport and tour buttons and they say it doesn't support them. Since my old cd is behind the buttons and the new one is only where the screen is , i disconnect the old one, will those tour and sport buttons work in a normal smaller multimedia system? Thanks in advance

what i want most from this upgrade is a seamless and easy connection of my phone to the car - listening to spotify via bluetooth. Android auto to use the phone trough the multimedia would be nice. I see those units provide fast charging via USB which is also neat. I want fast boot ups and not to drain my battery - i see this mentioned a lot. And hopefully not to lose any options for my car like comfort settings - sport, tour buttons, steering wheel buttons.

"Android auto to use the phone trough the multimedia would be nice."
Neither of these are Android Auto.
I like the quick charger USB, ambient light control and IPS screen of Ownice. Plus, it does have Android Auto and CarPlay but you need to pay extra cost.
I normally don't answer these kind of topics as it is a never ending story, but maybe I or others can use it to copy around in likewise questions.
They are more or less the same when it comes to the software. They are FYT based and have support for the several versions of hardware.
But anyway, for all units be it FYT based, MTCx, TSx, AC8227, etc., etc., FIRST compare the hardware:
Check whether the screen is TFT/IPS/QLED (in increasing quality=readability). Go for nothing less than 1280x720 (1024x600 is not good enough anymore, but in the end it is up to you).
Check which FM-chip (from low to high):
TDA7786x or Philips (NXP) TEF6851 => budget chip without RDS.
TDA7708x => middle segment but good enough
Philips (NXP) TEF6686 => top FM chip
Check which audio chip (low to high):
TDA7388 -> budget, not good.
TDA7850/TDA7851: Both good. 7851 has slightly less power output with slightly less heat dissipation. Less chance of overheating. The TDA7851 has almost everywhere been replaced with the TDA7838, which should be identical in quality/performance (no idea, google around)
DSP: nowadays mostly ROHM BU32107. (Earlier ADAU chips are not so good but seem only to be used in MTCx units.)
CPU (fast to slow): UIS7862 (Unisoc ums512), SC9853i and PX6, PX5 AC8257, PX30, AC8237 and PX3.
This order is a bit discussable, but the uis7862 is definitely the fastest currently.
Memory: minimal 2GB, 4GB is fine. Some prefer 6GB but that is actually not necessary.
Now back to the FYT models you are mentioning. They are more or less comparable. It "seems" T'eyes support is better, but I leave that to the owners (Don't want to start a flame here )

What? Android Auto?
You are going to buy such an expensive high-power full-fledged full functional Android unit and use it as a cheap emulator for the restricted Android Auto?????
I really, really don't understand these kind of arguments. If you want to use Android Auto, for which you indeed sometimes need to pay separately, then choose a cheap unit which supports this as well.

Android Auto is crap
When people think about buying these android head units I don't think they quite get the idea that these are pretty much full-on android tablets complete with their own android operating system. There really is no need to run android auto. Things like spotify.... youtube... siriusxm... etc... can be downloaded from the google playstore and run directly from the head unit itself. All you need to do is supply a wifi hotspot from your phone, or fit the head unit with its own 4g card.
Thanks guys, really useful answers! About android auto - I have, had no idea it wasn't that good. I never had a car with more than a single colored screen and always see adverts about new cars which specify they have android auto or apple car play as such a huge extra. After all isn't this to link the phone to the car system and operate the phone from the display? What if I receive e call ? The Bluetooth/wi-fi connection will allow me to answer it from the car media? And lastly i really want to have it lazy - for example i get in the car - my head unit and the car connect somehow , can i make it play Spotify automatically ? is there something like Bixby routines or.. can it happen at all? Or actually i can do it from the phone - when connected to that head unit to play Spotify like I have a program to play automatically when it connects to a certain speaker? Thanks very much again!

I have a simple bixby routine set up to turn the phone wifi hotspot on for use with the head unit, and then off again when I turn my jeep off. Of course the head unit automatically connects to that hotspot when it sees it. It's all automatic. I don't have to pull the phone out at all.
You can downlaod a tasker to start Spotify automatically if you wish.
Yes, your phone's bluetooth will connect automatically for phone calls.

Bixby is Samsung only.
You can also use Tasker/MacroDroid/Automagic/Automate/etc. to do what you do what @Bob_Sanders is doing with BixBy.
When you switch on the unit it connects via BT to your phone. That triggers MacroDroid/Tasker on your phone for that BT device (the unit) to switch on the hotspot, which the car unit on its turn then automatically connects to.
And when you switch off the car/unit, your BT connection is broken and the phone hotspot is stopped.
Works all the time for me.
Wow!
The Ownice has a HUGE array of inputs/outputs on top of the normal ones... pretty impressive
Dual sub outputs
HDMI output
Quick charge usb
two rca video outputs
Atmosphere lighting control
