I tried the search function on this forum to find out which units support HD Radio, but couldn't find anything useful.
When I try to google for HD Radio android head units, google just gives results of units that can play HD videos, and have a built-in radio function, which is not the same as HD Radio.
Are there HD Radio android-base head units out there?
From what I've read, someone has figured out/is working on RDS, but I haven't been able to find one with HD Radio. I'd really like to find something already setup for HD Radio, but if that's not out there, has anyone used an SDR dongle to get HD radio, I'm even open to Raspberry Pi based solutions, if it's straight-forward and reliable.
Any help / thoughts are appreciated,
Thanks

I have not seen any Android radios with a HD radio option. There is the standard boxes that you could hook and use. A demo Android program to get HD radio. I have a zoom HD Radio tuner, just have not wired it up and tested out the beta Android app. In theory you could hack the nu3001 newsmy radio application for serial control of the HD tuner

I notice that there are a few Android head units support with the DAB+ option. Do you have any ideas what's the difference between them?

DAB audio is supported in Asia and in Europe, not in the US.
In the US we have HD Radio.
I haven't been able to find an Android head unit that supports HD Radio.
I wish, I loved it in my Alpine. In fact, I wish there was a way to hack my Alpine TUA-T550HD and use it with my android radio.
I can't post an external link, but if you search eBay for "samsung HDRMUHHN00PTA", there is a realitive cheap HD board.
Now if we could find someone with the time and know how to show us how to interface these to our head units, that would be awesome!

That would be cool. There is nothing out there packaged with the radios for HD Radio
Sent from my HTC One_M8 using XDA Free mobile app
we don't have a solution. I purchased a SDR radio dongle for my Nexus 7 2013 tablet and got it to play FM and AM radio stations using SDR Touch. I tried using Wavesink but it only supports DAB+ and not HD Radio. I'm not exactly sure why nobody has written an HD Radio app as broadcast is free. I sent DTS who owns HD Radio? a email message asking what's up.
Wavesink also has very little development itself and can't really tune well for stations not in perfect clarity.
SDR Touch is very advanced as it allows you to manually scan through the entire radio spectrum. Sadly it does not support DAB+ or HD Radio. you will be able to view the channels though, but nothing will be decoded. digital signals will have a very squarish shape vs sine wave looking analog unencrypted radio. It is a very straightforward advanced app but offers no audio decoding capabilities.
So these two items would get you the basic hardware:
Tuner: http://www.mo-co-so.com/Directed-DMHD-1000-HD-Radio-Receiver-p/mcs-dir-hdr.htm
USB Interface: http://www.mo-co-so.com/HD-Radio-to-PC-Interface-p/mcs-mjs-hdr.htm
I think that interface also works on some XM tuners.
I've got a link stored in my 'tool chest' of an app that does some very basic tuning of these devices, but it should be pretty simple to extend a better UI to it (as @blacklistedcard mentioned, we have source code for the Newsmy NU/NR series devices, and their radio app (while not pretty), would be a good starting point.
Looking for same
I stumbled on this post in search of something similar.
Found this: https://www.amazon.com/OttoNavi-TY0...ments=p_n_feature_three_browse-bin:1293725011 which boasts of built-in-HD Radio in the description. But I am not sure about the operating system on this one (OttoNavi has other Android HUs).
If there was a way to replace the native onboard tuner with the Samsung one mentioned above, it might do the trick.
Then there is this: http://www.discountcarstereo.com/ca..._Radio_Tuner_for_Gateway_Connect-p-17743.html which may not integrate to provide RDS data.
Lastly, if using Android HU then there is possibility of mirroring your phone and use an app to stream HD channels (I imagine this would use the data).
Those are my thoughts after some preliminary search but my ideal is built in HD radio with navigation on a Android HU (within budget)...... still dreaming!!
From what I read (but might have misinterpreted) The Radio ICs in many of the HU are HD ready (TDA7786 is one) but looking at the data sheet another IC is needed to process the HD info received. Then you would need the radio app and possibly the MCU to be modified to allow all that info.
Now based off of Zaphod-Beeblebrox comments above, I was using that Add on HD tuner with my NU3001 radio. With XDAuto and Tasker I was able to use aux in to feed that tuner through the HU, along with an app someone made a couple years ago. I don't have the source for the APK but I still have the APK.
Right now, outside of a touch screen issue, I have the NU3001, the APK and the HD tuner working on my bench. You would need a switch mounted some where to physically power the radio on or off. sometimes it 'gets lost' but I used the HD tuner quite a bit. I will say I needed Xposed to resize the APK to fit the screen
I would like to try to integrate it on my Joying PX3 through the Aux in. i think it can be done, I just have not tried it yet. There is some source code on GitHub that should be able to be built to an app, but I was told it is not as nice as the APK I have. I wish I knew how to code for android, I have a bunch of ideas that would make the HD tuner a viable addition. If anyone one is interested in looking into this, I am more than happy to share what I have, as well as beta test what you will come up with.
@-=Jeff=-, I can code an Android APK and am interested in doing so. I really I would like it to work with the USB interface and the tuner module.
So I had my MTCD out today for the PX5 upgrade, while out I tried my HDtuner, I found that the communications to it (USB) don't always work. meaning I get a connection, then then within 23 seconds it stops. it as to be an issue with USB Host as a couple of the host check programs state It is not host supported yet I know things work. anyway, I used App Settings and xposed to get the display for the HD to be correct, if i can get the communication to work, then it could work in the car. i determined it was the app as if I use the actual controller and piped audio through the aux in is works great.
I did get this from joying on twitter: https://twitter.com/carjoying/status/898486036283539456
I would think it would be easier for them to replace the FM module internal and add the code for it. most those chipsets are HD ready, but just need some added ICs for decoding/processing
I know this is an old thread, but just wanted to ask if something like this would work? https://hdradio.com/get-a-radio/car-radio/dual-hdm90

bass_rock,
If you are still interested, I've got a Directed Connection HD radio kit and can get the USB adapter cable. The source for the USB adapter says it is Linux compatible, and apparently they include some PC based api's on a CD, but don't know about Linux source. I can loan you a kit, and will contribute the control cable to the cause, if interested.
FWIW, the Directed Connection and Visteon units appear to be the same thing. They are available on eBay for around $35. In addition, Kenwood had a similar adapter box that connected to many of their radios. It completely took over tuner functions from the head unit receiver. Here's a link to a Visteon unit on eBay.
https://rover.ebay.com/rover/0/0/0?mpre=https://www.ebay.com/ulk/itm/253638865139
Here's a link to the USB interface:
http://www.mo-co-so.com/mobile/Product.aspx?id=37436
I've installed a Directed tuner with the MJS USB cable on my car MTCD PX5. For software I'm using an open source FTDI USB library and the .net library that came with the cable. It took me a week to implement. My interface communicates with a front end by broadcast intents. My front end gui is textual with no graphics. I can also control it by SWC. My code is Xamarin c# compiled in VS 2017.

Congrats! Can you provide a screenshot? Does your app require root? If so, what must be done?
I've been looking at this app which must be compiled from source on GitHub, here:
https://github.com/lbdroid/AMFM_DMHD-1000
It is still being worked on, as of earlier this year. I understand that it requires root to provide some permissions to the serial connection, or at least an earlier version did. I haven't compiled it yet, but hope to soon.
There are also two versions of another app in apk form, without source code, here:
https://www.midml.com/~bob/radio.apk
and here:
https://www.midml.com/~bob/radio2.apk
It hasn't been worked on since 2016, AFAIK.
There was some earlier discussion on both apps here:
https://rootzwiki.com/topic/44698-04-jeep-tj-install/page-1
The discussion is spread thruout the thread.
I really think the Directed tuner is the only real near term solution. Some people have gotten an SDR to work with HD Radio just this year, but all of the development I've seen is for command line in Windows or Linux. Further, no one has implemented, or even started working on fall back/fall forward between regular and HD FM, from what I can tell. It also doesn't address AM HD Radio at all, although I'm not sure how many of those stations exist. Certainly none do in my part of the country.
Looking forward to your response and seeing your app.

I've attached a screenshot of an FM HD station and an FM RDS station. Most of the data is self-explanatory, also the upper unlabeled number is the signal strength and the lower one is the HD signal. There's an error message generated when I switch off, about no response, which I should clear when starting up again.
Happily it does not require root. I targeted Oreo, I don't honestly know if it would work as-is on Marshmallow, Nougat, or Lollipop. I'm sure it could be adapted. I'm working with a 10" screen so everything is readable. I have in mind to add large text in the lower right with the current frequency, callsign, artist and title, for easier visibility.
There's a little issue about USB permission. Presently it needs to be granted each time it connects, which I'm doing via Tasker (react to the permission request dialog and click it with the help of plugins). I tried the standard technique to remember permission, however it interfered with another USB app. I imagine that could be worked out.
Another issue is that when I start the car, if the radio is already playing, it enters a weird state and the connection has to be closed and reopened (see buttons in the dialog). I'm thinking I could solve this in hardware by maintaining the ACC signal until the USB disconnects. As for a software solution I don't know if the Windows app has the same problem, but it's installed now so I might possibly buy a 2nd unit for bench testing.
Other than that it's quite usable. I just installed it in the car day before yesterday and got the kinks out. The GUI is not intended to be great looking, I used it to test the interface. I believe in avoiding touching the screen while driving, and I can tune (as well as adjusting volume and changing audio source) from the SWC. That's handled in a different app.
Also for reasons I do not know (yet) the RDS text is missing a couple of characters on the end. Maybe that's the length limit of the RDS spec and the scrolling RDS field is the only way around it. I haven't added a button or intent code for AM yet.
The GUI can be hidden and restored with no problem, communication is handled by a persistent service.
My HU is set up to keep apps alive when it goes into sleep mode. In case one didn't or can't do that, it should work to rename the package to com.hiworld.*, which is generally included in the hardcoded whitelist. Or it would probably be adequate to use an available method to launch the app on wakeup, it searches for the USB device on startup and also detects if it is plugged in afterwards.
Currently when reconnecting the service restores the last station. It does not currently store that to a file.
So I guess there are some questions, but I've succeeded for my own purposes. It's likely that I'll work on it more in the future but it seems stable for now. From what I've read the software-defined solutions are not that great. The tuner that came with my HU is not that great either, I tried the Seek button in a rural area and it locked onto some static.
Thanks. Can you provide a link to the apk? My head unit is on 7.1.2 that 8 haven't rooted yet, so I can see if it works on that. I have an interface cable coming early next week, and already have a Directed unit. I have a 7" screen, so I could give some feedback on readability. I agree that larger type for artist, call sign, etc, would be nice. Are you considering adding presets?
Thanks!

Hello everyone, I purchased this unit (VW submodel) few days ago. Picture attached.
it works great.
8"
pure android
1ghz cpu,
1gigs of ram,
4gigs of flash + microSD,
capacitive.
Does anybody have the unit with same chipset so we can exchange some info? For example, I can't find an entrance to hidden menu that was presented to me at first boot,
I don't know how to restart the unit, and I have a slight issue with car battery draining.
To be straight on topic, I have modified stock radio application to be more... ... presentable It was terrible, colors were out of this world
This unit came rooted. So I could easily replace the stock radio app.
If somebody needs it just let me know.

Could you post a link to the stock radio app. I have the S150 Head unit:

Which has now been updated to Android 4.03 but the radio app is terrible!! Spirit Radio will not work either so would be nice to give yours a go on the off chance it is compatible.
Oh and to enter the "hidden menu" on the 2.3 Android S150 you dialled "*#98723" from the phone app. However this doesn't seem to be working after updationg to 4.03 but I'm going to post it on the S150 thread and see if anyone knows how to get into it so have a look there.

The pictures of the unit isn't enough to verify which model you have. The problem is that the faceplates are crossed used between several manufacturers. So, going by the picture alone is not enough to identify the unit.
If you already have the model check the "About this device" in Settings application is an easy way to identify your model. You can also run "cat /proc/cpuinfo" or "getprop ro.device.fingerprint" in either "adb shell" or a terminal app then check for the keywords below from the returned syntax. If it does not match any of them then post the output here.
A way to differentiate between the different Chinese Android head units is by the exact processor included:
Allwinner A10 (sun4i) 1.0 Ghz Cortex A8 Single Core processors in the TVBOX family.
Freescale i.MX535 (imx53_smd) 1.0 Ghz Cortex A8 Single Core processors are usually found units in the OUKU Unbranded family.
Mstar MST786 (cedric) 1.0 to 1.2 Ghz Cortex A9 Dual Core processors are found in the units in the AN-21U family.
Samsung S5PV210 (smdkv210) 1.0 Ghz Cortex A8 Single Core processors are found in the units in the S100/S150 family.
Samsung Exynos 4412 (smdk4x12) 1.7 GHz Quad Core processors are found in the units in the WD8801 family.
Telechips TCC8925 (m805s) 1.0 to 1.2 Ghz Dual Core processors are found in the units in the TCC8925 family.
While I do suspect you have the Allwinner A10 as noted by the title of the thread, you might want to verify it to make sure you can post in the correct thread.

Thanks for your app radio i will test soon.
Overall I like it too, but have a few problems that I think could be solved with an software update, for example:
switching sound beetwen radio and android sound is buggy in my unit, Bluetooht module is not visible for android, so you cannot use to connect with obd2 device.
I think stock player is the best option because other players take more time to launch and if you are driving, you need a very simple and direct interface.
Otherwise,I found default launcher slow and choppy so I installed holo launcher, it runs smoother than go launcher.
I'm looking for a minimal interface when I´m driving so I test some car dock apps and widgets. I am currently using Car Home Ultra, I use autostarter to run the app when android boot and I use also a volume schedule app so android volume is set at boot.

I hear that this radio is not compatible with cheap OBD2 adapters, people have purchased another bluetooth dongle to use with radio for OBD2.
(there is compatibility list somewhere) and than it works. And then there is another problem, you can't use USB hub to plug in multiple devices to USB, power is too low. So you have to use powered USB hub to have wifi adapter and bluetooth adapter plugged at the same time.
I haven't noticed bad transitions from FM to mp3.
Nice tip for autostarter app, I was looking something similar, thanks.
Poweramp is quite simple, it starts automatically if left working when you turned off the car. But the sound quality is far better-deeper (costs 4$ I believe, 0$ on torrents )
I use "Screen Dimmer" app (widget) to dimm the screen when driving at night.
As for launcher, I have swithched it to APEX launcher and looked no further. Fast, minimalist, customizeable...
My unit had NEXT launcher, and that was tacky overkill. I guess that is also GO launcher derivate.
I have slight problem - noticed that unit really never sleeps. I was poking around my cellphone and noticed it had automatically connected to car bluetooth. But car was locked and shut down in the garage!
So I tried another smartphone, and it also found car kit as active!
So today I have disabled that bluetooth service.
Do you also have some sort of "canbus service" active?

I hear that this radio is not compatible with cheap OBD2 adapters, people have purchased another bluetooth dongle to use with radio for OBD2.
(there is compatibility list somewhere) and than it works. And then there is another problem, you can't use USB hub to plug in multiple devices to USB, power is too low. So you have to use powered USB hub to have wifi adapter and bluetooth adapter plugged at the same time.
I haven't noticed bad transitions from FM to mp3.
Nice tip for autostarter app, I was looking something similar, thanks.
Poweramp is quite simple, it starts automatically if left working when you turned off the car. But the sound quality is far better-deeper (costs 4$ I believe, 0$ on torrents )

Screen dimmer app its a good idea, i will try it.
I didnt notice problems with sleep, i will test later, but perhaps you check bluetooth conection very soon, I think device is runing a few minutes after you remove car key to shutdown android.
I dont have any kind of "can bus service", I only have a configuration vehicle app, so i can configure stering wheel buttons and other stuff but nothing about canbus, maybe that is especific for VW.
P.D Sorry for my bad english....
I was considering this HU for my 2016 VW Polo since I don't care much about having a DVD slot. The title for this HU says DVD but it doesn't sport a drive. Though the spec seems good (RK3188) and the price isn't much either I didn't find any reviews or information about this HU on XDA (or outside).
There are couple of places this is being sold from Ali express to GearBest and also on their own website.
Does anyone have any thoughts on this one? Specifically I was looking for community support (root, custom firmware). Since this sports a RK3188 chip can other ROMs be used on this? Also the HU has a very thin form factor (compared to other HUs) - so would heat be an issue?
Who knows?
It doesn't have a volume control knob, if you can live with that. Personally, on screen adjustments for volume, track selection, "back," and on/off is very unhandy and annoying. You can't just reach up and adjust it with out looking. Also the volume steps of the touch controls are not always small enough to set a precise level. These units, with no US contacts or service, are a pain if you need something. Carjoying is in the US and quite responsive. Updates are also made.....who knows about those other relatively unknown products. They may never update and may no work with other software. I have never seen a 9" screen wonder if the thin bezel is just a half inch smaller and uncovering the edges of an 8" panel. This is just conjecture but perhaps worth considering.

Thanks for the response. I ended up placing an order for this unit instead. I dropped the other one mainly due to there being hardly any orders and reviews. I also did not get any proper responses from the sellers regarding that unit - probably since its new and they are themselves unaware of its features/fit. I agree about the support issues but I also had a tight budget and as long as it works fine :fingers-crossed: I should be OK. Importing these into India attracts a sizable customs duty The unit I bought costed me about $190 shipped via FedEx so I expect the customs would be proportionately lower.
Regarding the volume I have steering wheel controls which should serve the purpose of physical buttons. Though I agree that having a knob is more convenient I also kind of like the flush surface of these full touch units - lesser issues of dust settling.
I will post an update here once I get the unit and install it. BTW the reviews for this on AliExpress are excellent - would love to hear from anyone already owning this. I asked the seller about rooting and custom firmware (kind of essential for android units) but didn't hear anything positive This lack of support and the fact that this is an AllWinner solution (R16 QuadCore Cortex A7) were the only two drawbacks I saw in it (given its price).
How to root Junsun Android 4.4.4
I purchased this unit also from gearbest and like some things about it, but question other things.
The good:
1. The unit is ridiculously thin for a car stereo. There is no CD/DVD player
2. Sound is actually decent. Little difference from the stock unit
3. The home page with rotating icons is cool and different. I can also put a live wallpaper behind it
4. Mirroring app works ok, but I'd rather tether.
5. I can play videos and music on a USB flash drive
The bad:
1. I can't launch other apps and listen to music at the same time. (i.e. when I load Google Maps, radio stops)
2. No native capability to bluetooth tether. USB tethering with EasyTether also didn't work.
3. There are no microsd inputs like other Chinese Android units I've see thus far. I can connect a USB drive to 2 available connectors routed from the back of the unit. This isn't necessarily bad. Just requires different process for rooting that's TBD.
4. Instructions are only in chinese. Don't know who really makes this device, or how to get their technical support. So far, gearbest has provided some answers, but they're far from accurate!
So that said, I'd like to root and install some different apps and drivers that might make USB or bluetooth tethering possible. And that might allow me to listen to radio or USB music or Pandora while I have something else like Torque or Waze running.
Here are settings from the unit:
OS Version/Build Version: JAX1602191130G-WQ-16EN
MCU Version: 201512161416-SLX7786-GEN
CPU Model: RKPX3
Android: 4.4.4
There is also a 'system' page, where I can go to advanced, press 1234 as the password (found it through trial and error) . A screen is then available to upgrade MCU or firmware. However, I don't know where the files should be placed for this screen to register them.
Any pointers on process to root this and/or install something like Malaysk Firmware? Thanks!

This is really bad since it defeats the whole purpose of an Android-based HU. Are you using the stock music app or trying something you installed?

I think all these units restrict the bluetooth to the MCU and is generally not available to other apps. Though I am not sure how Torque works.

This is a problem with most Chinese purchases - informed support is almost non-existent. However since you have an RK3188 based unit I think some of the support threads here may match your unit (at least partially). First try to get into the extra setting menu using the passwords given in the RK3188 threads and rooting as well. You need to find the thread that matches best to your unit/firmware based on trying out the various settings/tweaks. Don't flash anything till you are certain you are in the correct support thread. All the best!

I am sure that this is some soft/firmware restriction. Android 4.4 has a native support of multitasking, so it should be by default in any of core versions of this OS. Main problem that I didn't find any resources where this issue was resolved.
Mine will !

This is really awful - how can they sell a "Android" HU with such limitation? You should give the seller an earful and a bad review for the unit so they are forced to fix it!
I have the same unit also , the camera doesn't show when I am in reverse mode , the steering wheel don't work with the radio, rkpx3 model
I need to know what MCU is installed on this unit . Someone has any clues ?
You can have a glance at this Pumpkin HU for VW, http://www.amazon.co.uk/Pumpkin-Android-Navigation-Subwoofer-Multimedia/dp/B01D30XDXY/
Lol. Even on the official video where this HU was demonstrated , MCU version is 'unknown' ))) http://screencast.com/t/RnQxbkAZBaWX

I bought this device.
The menu is exactly the same, firmware is the same: JAX1603281325G-WQ-16EN.
There's a microSD slot on the front panel.
MCU version: 201601251011-SLX7786-GEN .
Built-in player and radio can not work in the background, and this is the biggest trouble. There is not a full solution is to install third - party players who know how to work in the background, for example: BlackPlayer. But unfortunately, in third-party players do not switch tracks from the steering buttons. Adjust the volume and MUTE works as it should, because these buttons are programmed for the entire system. I liked that as a quick call navigation, you can assign any button on the steering wheel and choose any app.
The unit is decent, especially for the price. But such silly mistake with a built-in player and radio can wipe out all the pluses. Wrote to the seller, promised to talk to the engineer, perhaps
Typo?

No. I have already found it when disassembled this HU. Its located on left edge of device. You can use it to flash ROM , or like normal SD... Now I working with stock firmware, trying to solve all issue mentioned in this thread. Its not so easy... bcz this MCU and firmware are not usual for this type of HU, and I didn't worked with this OS before ).

I noticed that the built-in player and radio do not have the manifest permissions to change the audio system settings ("modify audio settings"). Using APKEditor added this line to manifest, but to save, unfortunately, did not work, because I get the error message: the program is already installed and is missing a digital signature. If necessary I can put the modified and the original source code of the apk "music" and "radio"... Now are struggling with receiving the digital signature, the idea is APK Editor must sign the modified apk with the native signature. Apparently, there is some protection.
n the process of using the device revealed the following shortcomings (about the first two already written):
1. Not running in the background built-in music player . That is, when playing music you can't use Navigator. You have to use one or the other.
2. Not running in the background built-in radio programme. That is, while playing the radio you can't use Navigator. You have to use one or the other.
3. Not running in the background audioclub built-in bluetooth . That is, when playing music from phone via bluetooth you can't use Navigator. So you have to use one or the other.
4. After the completion of the incoming call via the bluetooth Protocol SOMETIMES falls off the sound of the entire device. Most likely, the audio service bluetooth does not give audio device. You have to reboot the head unit by switching off the ignition.
5. I really want the joystick on the steering wheel could switch tracks on ALL the audio players and not just on the built.
6. Lost sound player and radio when you lock the screen (press on the power button), which is very inconvenient at night, since I want to eyes did not detract.
7. It is unclear how sync contacts via bluetooth. Some appear, some don't.
I received from the seller working firmware, music is now able to work together with NAV. If anyone needs - let me know.
Hi all. I have a 2011 Hyundai Accent that used to run a HuiFei KGL4 Hyundai-specific 7" unit. It's been one rollercoaster ride with that unit, having to deal with the following:
1) Underpowered USB ports (had to solder a voltage step-down converter to amp it up for it to work properly)
2) The latest ROM forces me to wait 30 seconds for the unit to shut down after turning off ignition, otherwise my PKE car alarm won't trigger as all doors are generally closed within that time frame because I've already stepped out of the car. Funny piece is there's no way out of this even if I go back to an older software, or use an MCU that doesn't support sleep
3) Weak FM radio
After messing real bad with #3 above, killing one channel off of my FM radio (only right channel is working now) after breaking the electronic links for one of the caps needed, I decided it's time to let go. Not to mention that the reseller that I've brought it from is no longer responding when it comes to asking for replacement parts and Kai Ge Le doesn't sell parts from products that weren't directly bought from them. Malaysk' great ROM helped me get through the day for a while, but hey, when you want a fully working product, you gotta move some time right?
The next dilemma was: should I go with Joying or any other HuiFei-based Android radio and potentially deal with the same thing? Then I thought... man, it's time to accept I'm not too good with soldering and I can't risk messing another brand new radio just for dealing with the same thing.
Long-story short, I went with a not so known MCU / manufacturer / reseller combo this time around for hopes I'd get different results. It may be a bit of a challenge to get support from the community granted none of my searches yielded any results for the MCU the device is using, but man... with how the ROM of this new unit working fluidly as it is, I'm finally content.
Some distinct differences with HuiFei:
1) Boot-up time. Before upgrading my KGL4 to RK3188, boot-up time was 30 seconds. When I upgraded to RK3188 roughly ~15 seconds. In this unit? I don't even notice waiting for boot. It properly turns off USB connected devices so my battery does not get drained- tried for 5 days now and has been consistently fine.
2) Next / Previous controls. I did not need to install Car Service for Next / Previous to be consistent on non-stock apps (Radio, Music, Video apps). If I press next or previous in my steering wheel on, say, Spotify or PCRadio, the behavior is the same. It goes to the next / previous track as expected, with no additional apps or configuration needed.
3) RADIO - I can't emphasize this enough. In days where I just want to use the radio instead of songs from streaming apps, man, this unit delivers! It subdues the static / hisses well, and clearly picks up the same radio stations that I used to have in my car's factory radio that the KGL4 one struggled to pick-up.
4) Bluetooth function - I was never able to get my KGL4 unit to pair with my OBD2 device, no matter how many times I've back-read in the different threads. In this new unit, it was able to detect and pair with it the first time I tried! The plus part is that the Bluetooth config of this new unit allows you to enter the pair code for devices that requires it - at least on this one I'm sure the HuiFei units cannot prompt for the pairing code of the other device.
5) Support for external hard drives. I was unable to connect a 500GB external drive in my KGL4 before until I did the USB mod. For this new unit, it supports it right off the bat. No mods necessary.
6) There's an actual WIFI antenna!
Another plus for me is the screen size upgrade. The new device has 9" of real-estate. I did lose DVD functionality and potentially not have the option to update the software to 5.1 (runs on 4.4), but I can live with those. If anyone's familiar or has the same MCU as mine, or shares the same software build, let me know. Maybe that will be a good reference for anyone who'd potentially buy units from them. In the meantime, TC Car Audio has a store in AE if you want to inquire (Store ID 1360064). Looks like they also have a couple of 5.1 devices, just not sure if it shares the same MCU / ROM combo.
DISCLAIMER: I do not work for TC car audio. Just passing along the positive experience I have with their product, and hoping to help others see that there are better options out there beyond the more known brands.

I'm more interested in this part. I wonder why this works on your unit, but not the majority of Anrdoid head units?
Can you try Pandora or Google Play Music? Does the app have to be open and in the main view for it to work? or will it work while playing in the background. Like say you are watching the Navigation with Pandora playing in the background from a Pandora app on the Android head unit, if you hit a track change with the Navigation app on the screen will it still change tracks?

Microntek head units are using its own "layer" of virtual keys mapping (irkeyDown/up). It is useful from their point of view, because you have possibility to use long press behavior on hard keys. Android has its own definitions of key events and actually it is good habit to use them (in case of developing "steering widgets" and players developing as well). Probably microntek finally started to broadcast Android's defined key events among the system which caused support of many media players .
But that is only my theory .

I couldn't try Pandora given where I'm at. But yeah, Google Play Music works just as same as Spotify. No need to have the app open, I mostly have Car Launcher Pro on screen OR my GPS app and I can hit next / previous even if the music apps are on the background.

Hello friend,
This is Nicole from Kaigele.
Sorry to tell you that,from your posted info and images,this unit is not from our factory.Maybe you need to contact your direct seller to get more help.
thanks

Hey,
I have been using an ownice c200 up until last year, when the unit let out the smoke and died. I am using the original RNS510 and that thing is driving me nuts… I am thinking of buying a new unit and have been browsing the forums here to find answers to the issues I will run into. It seems that to turn on the sound system and use the camera I would need 2 more special can adapters.
When I installed the ownice unit I did draw up a pcb with an rgb-composite converter but never came about to build it. Not having the camera was only a pain when I did hook up my trailer…
To turn on the amplifier I built a little µC box with a CAN Interface, debugged the bus with the original headunit in and then wrote a simple program that listens to specific commands, turns on the amplifier and also keeps it turned on. My intention by then was to find a way to send the commands via the CAN bus adapter that came with the c200 but since that little box in my glove compartment did the trick I never got around to investigate further. Also I am no andriod expert...
From what I have found here the communication to the CAN adapter is done via a serial interface. There are no actual can frames transmitted and all the filtering and conversion is done in the adapter. Maybe someone can point me to threads dealing with the CAN adapters. Has anyone here done a custom CAN Interface? Can you configure that interface to listen to more IDs? Can you get the raw CAN data from the interface?
My ultimate goal would be a can interface that gets configured via the headunit and then just forwards the commands in both directions. The rest would have to be done in software on the headunit.
Cheers,
Christian.

There are no actual can frames transmitted and all the filtering and conversion is done in the adapter. Maybe someone can point me to threads dealing with the CAN adapters. Has anyone here done a custom CAN Interface? Can you configure that interface to listen to more IDs? Can you get the raw CAN data from the interface?
My ultimate goal would be a can interface that gets configured via the headunit and then just forwards the commands in both directions. The rest would have to be done in software on the headunit.
Cheers,
Christian.

It sounds like you're mostly done with the hard part of the job already.
My suggestion would be to avoid trying to interface with the chinese radio, but rather to work around it using as much as you can of custom code.
From what I gather, you already are able to "send" most/all of what you need with your little uC rig, but now you probably want to send commands back to the radio, right? The best way to do that would be to implement an HID keyboard on the microcontroller. Just plug the uC into the USB, the radio recognizes it as a keyboard, and you can send in commands, like volume+/-, etc.
Note that you can use the standard outputs from the radio (like the AMP ON, ANTENNA ON, CAMERA ON, which are just 12v binary signals) to feed that data out to the microcontroller.
The reason behind all this is to get rid of all the extra canbus decoders to get everything working. I already had to put my can node inside the glove box because I could not fit it behind the radio. Since the unit can send and receive commands, why not write the software for the headunit instead the microcontroller. That way also others might benefit from it and it would be possible to play with the MFD.
Hey guys so I have an Alfa 159 and bought one of these head units:
Edit i cannot post a link however its the generic A-media Auto alfa 159 head unit which can be found on google
now I was speaking with a friend of mine who explained that the roms are "cut back" and removes some features and full blurtooth control/ support is one of them
I am reasonably ok with computers but never ventrued into any sort of custom android stuff and the extend of my knowledge is " i know you can get custom roms" i hdon't know how to do them or use them etc.
I have some bluetooth modules i can control from my phone in the car (lighting and actuators) but would love to be able to do it from the head unit
Would it be possible to get a custom rom for this head unit and if so any guides at all?
I would like to point i did have a search but honestly i am not totally sure what I am searching for and searching sepcifically for this head unit didnt help.
Thank yoiu very much
It's not so much that the ROM removed bluetooth features as much as it is how the bluetooth module is integrated to the HU. There's 2 system boards that make up the HU. The SoM has the Android system and is basically a tablet motherboard with only a display, audio and USB connection. The MCU provides a USB hub, audio preamp and power amp, connectivity to the car and the bluetooth module. The bluetooth module is treated as a headset controlled through a serial connection with AT commands and this is where the problem lies with using bluetooth with any apps other than the built in ones. It works for ODB dongles so it is possible but if the functionality you're looking for is not already implemented I doubt someone else would be able to add it to the MCU ROM. All I can say is try and see if it works.
Maybe you can try to connect a USB bluetooth dongle the issue here would be Android drivers.

Thank you, sorry for late reply.
A friend of mine figured out with his that it was "nuked" in the software allegadly. the bluetooth module is a generic module but unfortunatly I am not massivly clued up on reflashing roms or even where to start especially on a head unit which is a shame.
My friend unfortunatly has since moved country so I can no longer ask him to take a look
I don't suppose anyone else might have an idea to this?
this comes up often apparently nobody give f*ckall to address this issue.
^ Thats a real shame

i know, my radio is great, does everything great. I just want to connect bt to my ham radio and use this as the head unit. and I was thinking about using those bluetooth valve stems so i can see the air pressures in my tires, looks like those wont work either.

Have you considered that these units work for the intended use and if it doesn't work for some obscure use case the desire to solve a problem for single users is limited. To expect others work on an obscure problem for you seems a bit entitled.
Have you considered taking the lead on this issue.
Bumping to see if ANYONE has came up with a solution, maybe an external dongle?
