Android HU: Junsun DVD-9.0-AN Android 4.4.4 9.0 inch

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 !

From home screen touch Radio icon, then from Radio app touch home icon on top left, back to home, start app you want. Radio continues on my radio from CarJoying. Works fine;

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?

Is that a typo? There is NO microSD slot on this unit. You can connect a USB Flash Drive to the USB connections on the back of the unit though.

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.

Setup/install question

So jumped in with out doing enough research.. I just installed one of the double din android units in my car. I was able to get everything wired up and running. But not much is working well.
I got this unit
GCS APEX ANDROID HEAD UNIT W/ GPS - 2015+ WRX / 2015+ STI
Android Operating System Version: 5.1.1
Processor: 1.6Ghz Cortex A9 Quad Core
Memory: 1GB RAM, 16GB flash
Stereo Power: 4x50W
So the unit itself seems very slow. I installed 2 apps. Spotify and Waze. The apps take a long time to load/open.
Spotify. Ok this is odd but not sure if its normal. I open spotify and I have the HU paired with my hotspot. It loads and starts to play but the sound is awful. I am not able to control anything via the headunit for sound such as fader/balance/eq. They don't do anything. Now if i open spotify from my phone and cast it to the HU i have all those controls and it sounds 100x better but the volume can be adjust from the phone and have to set that low. Is that normal? I have tried to get the USB to work and it will charge my phone (iphone 7+) but the headunit won't recognize the phone at all. don't even give me an option to use it via usb. I can also connect via bluetooth and stream that way but its similar where I can adjust volume from the phone. Sorry if this is really n00bish but thinking maybe its a setting? I can't seem to find anything.
After doing some reading i guess the 1gb was not the way to go but stuck for now. so any suggestions? I just want to be able to use Waze, and spotify and have the unit respond. When I click a button the delay is not a second or two but over 50 seconds and seems like it just crashes. I clear the memory and dont' have any live wallpapers running just nothing seems to be responding at all
Hope this makes sense and or someone might be able to give me some insight. Thanks for any help.
I can't post the link to the actual unit since I don't have enough street cred with the forum yet.

Any thoughts?

radio
My radio has the same specs as yours apart from the android version (4.4.2), i can confirm that Spotify and waze are both up and running within a second or two.
It does sound like you might have a faulty unit, is it possible to return it ?
You could also try a different rom but will kill any warranty I guess.

Yah that is what i am worried about. The vendor is not so eager to exchange it. I am going to take some video of what I am talking about maybe that will add some detail. Maybe someone will see it and point out that I might be doing something wrong. Not sure but very frustrating.

If yours is a MTCB/C unit (check the MCU version, it should start with this either MTCB or MTCC) you can flash a 4.4 ROM.
I also received my unit with 5.1 and downgraded to 4.4.

So tried a bunch of things over the weekend. No luck. I did do a factory restore and then was not able to even log into the play store at all. Google services kept crashing. I tried all the trouble shooting I could find online with no luck. Also I was not able to get the USB connection to see my iPhone. I could plug in a thumb drive and it worked fine. Are these just not able to use an iPhone at all? Not sure if anyone has been able to get the USB connection working between headunit and iPhone.
I sent the unit back hopefully getting a replacement to continue to try and get it to work. If not guess I will look for something else.

New Android 7.1.1 PX3 Unit from BonRoad - Any Info or Feedback?

https://www.aliexpress.com/store/pr...32699671881.html?spm=2114.12010612.0.0.KbDCzA
The UI and other specs are very similar to the HotAudio test preview (thread here). Has anyone had a chance to get their hands on one of these yet? I'm deciding between this or a Joying unit.
Any input is appreciated!

PX3 RK3188 Android 7.1.1 DVD VW GPS 2G ram
Just received and installed this Head unit in my vw touran 2004.
It looks like the specifications are the same : https://fr.aliexpress.com/item/Pure...32582906631.html?spm=2114.13010608.0.0.UFTkAD
The unit is a Bonroad C1120801A4/A5 (RK3188 Android 7.1.1 Lecteur DVD de Voiture pour Octavia Fabia Praktik EOS GPS Navigation Avec 1024*600 HD 8 "
So far, i'm satisfied with the unit :
- Radio is now working and stable .RDS works fine (with the last DCMU update). (You need to put a double fakkra antenna plug to get the radio stable on vw cars)
- GPS IGo is fine but not in French, Waze great
- canbus is functional
- Wifi rear camera ok
- BT external micro (mono) installed, i need to shout/YELL (it is an issue...)
When calling, both mic works (front mic and ext. roof mic)
google voice research unusable
I'm waiting for documentation from the supplier as there were no instructions in the box.
Do not hesitate, if you need more informations, pictures and tests. :good:
I tried Kingo root but it failed.

I also bought a car radio on aliexpress similar to yours. Px3 cortex a9 for ford focus c-max.
I have exactly the same worries as you with the microphone, the one integrated in the facade I have to stick my mouth on and scream.
The one who plugs externally is the same thing.
Many people talk about a worry with frequencies that are not the same in china and here
300-3400 for china
50-7400 for others
If you can root your device you can change the frequencies with Pimp my rom.
Personally I can not root it.

Thanks for the feedback. What's the boot time on this thing? Does it have a sleep function similar to Joying units?

About 15 to 20 seconds to boot. For sleep functions, I have nightlight or 15s 30s 1mns ect ...

I've the same unit but it doesn't detect OBDII adapter. Any solution?

After trying everything to get the microphone that works for the handsfree kit, I decided to cut the 4th leg of the bluetooth module and solder a mono microphone directly on it. This was my last option because I did not have the c32 connector. This has been a success. People hear me very well now.

I have ordered this one - https://www.aliexpress.com/item/4-C...32691433062.html?spm=a2g0s.9042311.0.0.MbBrvn. Waiting for the the item to arrive. The seller would ship it on 17 July 2017 (Monday).

Can you try the following and see if this gives you root access:
Goto factory settings and instead of typing 126 type *#hct#root#
This may give you temporary root access. Now you can install supersu or magisk to make the root permanent.
Note: I don't have this device or have not used any other Android HU; so I have not tried the steps mentioned above. I found this on the internet. Please try and let us know the result.

Is your Bluetooth scanning OBDII with this ROM ?

Hello, I bought this unit, but the 9-inch model without buttons and I do not use the search for voice, the free hands works perfectly for me, but for voice searches they do not work with the internal or external microphone.
Nor can I get programs with self-starting like the Radardroid service start only with the start of the radio, I have to manually activate it at each radio start.
I also have no rear camera, only parking sensors, and every time I put the reverse gear turns off the screen and the voice of the radio to try to connect to the back camera even if I do not have it, this did not happen with my previous radio with android 4.4, only with this new one with android 7.1.2.

Well you're right, if I have the auto sleep option enabled, but programs like Radardroid can not start automatically with the radio, I always have to start them manually.

Hi everyone!
I have a similar unit.
I think that the problem is with android version. In our case 7.1.1.
I had a problem with my OBDII reader and I updated my unit to 7.1.2 and fix it
Now with 7.1.2 I have the same problem with microphone and also I have a problem with USB cameras. Only the DVR app can connect with but only the first time. If I close the DVR app and open it again, camera dont work.
I want to use the USB front camera with Mapillary and iOnRoad but I cant.
Any idea?
Where can I donwload a previos android version? for example 5.1.1 or 6 perhaps its would fix the problems.
Thanks!

I've had a Hizpo 7" no dvd with buttons mcu xrc 2.54 android 7.1.2 2gb 16gb for a week. Came this way so I can't say about previous versions.
My bluetooth microphones (both) work fine for me, calls hear me fine. Even just the internal mic seems good.
I haven't had any bluetooth connection problems.
Android does not see any microphone, there is no speech input in keyboard settings, google voice search hears nothing. Voice recorder apps hear nothing.
Tried a usb mic but that did nothing.
Can't get usb camera to work for DVR. RCA CVI cam works in DVR but doesn't record, does not work in FCAM app however, though rear does.
OBDII worked fine when I first tried it, haven't messed with it since.
Display clear and good.
Haven't seen any bog, even when running nav, audio, video etc.
Audio is so so, lots of noise. Radio reception seems great and RDS works too. Needs an amp.
Wifi reception is great, just a little antenna on the back.
I really like it but for the lack of voice search. It's really fast, I have a load of apps and still tons of space. Runs everything so far.
Nearly instant on, radio is playing in under 2 sec (probably 1).
GPS works good so far, finds my location in maybe 10 sec or less usually. I haven't been thru Pittsburgh yet to say how well it keep its signal.
I just got MTCtools and dialer and will start messing with them tomorrow, hopefully I can get a mic input to android and get voice working, then this will be really great!

Hi
This is my second HU I had a Xtrons PF75Q5FA, the Joying is better than the Xtrons.
All the basic functions work well. No problems with the bluetooth or radio that sum people have had.
The WiFi seems very slow, connection signal strength OK just slow.
The display suffers from reflection making it hard to read at times, I fitted an anti-glare protector which helps.
The stock launcher is OK.
Tried using "Carwebguru" which I prefer, unfortunately when you press the physical 'Home' button the unit goes back to the default launcher,
using the soft 'Home' button works fine.
Generally I am happy with what is a basic unit.
If you would like some pictures I have had the unit apart (soldering of BT/WiFi cables is bad)

Tried using "Carwebguru" which I prefer, unfortunately when you press the physical 'Home' button the unit goes back to the default launcher,
using the soft 'Home' button works fine.
Generally I am happy with what is a basic unit.
If you would like some pictures I have had the unit apart (soldering of BT/WiFi cables is bad)

UM135N4PX5 owners - how are you liking your head units? I'm inching closer to buying one...

Hi
This is my second HU I had a Xtrons PF75Q5FA, the Joying is better than the Xtrons.
All the basic functions work well. No problems with the bluetooth or radio that sum people have had.
The WiFi seems very slow, connection signal strength OK just slow.

Have you set Carwebguru as the defalt launcher in settings? The new one wont be able to do it on its own.
Soldering a legit SMA and antenna does wonders, did on my MTCB. My Joying PX5 wifi was ok, nothing to bother with changing.

My I ask what all you would like to do with this unit? What apps, music, nav, other? Listen to mp3s or streaming music? Your desired functions of the wheel controls?

Here's what I'm hoping for:
Run a custom launcher
Run a few useful travel apps (GasBuddy, TPMS monitoring, trailer leveling app)
Be able to control what the source button on the front rotates through (AM, FM, SD card files, perhaps IHeartRadio, perhaps Spotify, etc.)
Backup camera
Video output (for GM's rear headrest displays)
I plan to use my phone as a wifi hotspot for any apps (i.e., GasBuddy) that require data.

Custom launcher: good to go
Travel apps: sleep may break functions, don't know.
Custom Source: This will require root, xposed, tasker, I only have ideas in theory in how this would work.
Backup camera:gtg
Video output: I believe video output will only happen from stock video app, it may be picky on formats, aspect ratio, etc..
About root, and xposed; Its not really fully tested yet. I've been able to do it over USB, other(s) has not. Even then my root is only temporary, it is lost on reboot. If your HU ever looses power (change car battery) you will have to re-root. I'm lucky that I can do it from my tablet, but it relies on the cloud (kingoroot), that does not make me comfortable in trying to future proof my head unit. Granted, you only need root once for xposed but there could be a feature or a work around that would suck to loose on reboot.
Issues with non stock music players. Spoitfy, for example will continue to play for 5mins after you turn off the car. There are workarounds, it's easier with xposed, tasker. Without root you have to trigger tasker off of wifi, or a ACC powered USB device to pause the music.
If you really like to tinker, I recommend the android headunits. Anticipate bench testing for some time before you install into auto.
I've posted about it before, but I'll again share my favorite piece of hardware.
RcJoyCon - Steering wheel interface
http://www.exinterface.com/cpjexc/
Works with CANBUS, IBUS, Restive controls, converts them to USB keyboard. When used with Xposed Additions, gives you crazy amount of SWC power. Single, double, triple clicks, double taps, triple taps, tap and hold, can all be task assignments in Android. It also allows to change button layout depending on app being used. I could't live without it, I "could" do "everything" from just my steering wheel controls.

Wow, thank you for taking the time to type this all up! Lots of extremely useful detail aimed exactly at my planned usage.
I definitely plan on a solid amount of bench time configuring whatever I choose before installation - this is part of the reason I'd like to order sooner than later!
If I get lucky and my unit can root over USB, then I'm okay with the power-loss behavior because I can reroot without having to remove the unit from the vehicle (I think?).
The Spotify behavior sounds pretty annoying. Is this a Spotify issue that I'll face no matter which unit I choose, or is it something specific to the UM135N4PX5?

Common bug of these android head units. Can't really recommend PX5 right now.
Look into Joying sofia 3gr, Intel, still learning alot, but its the best option right now.

Does Sygic Navigation& Spotify work with this Unit?
I just need Auto dashdroid Launcher, Sygic & Spotify

I ordered their new 4GB PX5 unit, but currently have an older rk3188 unit they sold 2 years ago. I've loved it, minus the horrible radio reception despite the powered antenna in the car wired correctly and turning on.
Anything that can be done on these units to improve radio reception?

Spotify will work. You will have to come up with your own method to pause and resume playback, on car start

@carter.w.jason
You have a PX5 and a Sofia. The Sofia units have a bug in their GPS HAL since the October ROM or so. It uses integers to calculate the m/s instead of floats. It means that the speed steps are going in 4 km/hr step up and down, instead of 1 km/hr steps. The GPSSpeedFix xposed module corrects this.
Does the PX5 have this same GPS HAL integer/float bug or is it functioning correctly?

Pumpkin AE0273B - Android 8.0 - 4GB+ROM:32GB

Website/Info page: https://www.autopumpkin.com/pumpkin...screen-octa-core-with-gps-navi-bluetooth.html
I ordered this off their website since it was cheaper than ebay/amazon by $30-$40 dollars. $309. Because my order was delayed as they waited for new units, they offered me an ODB connector (which did not arrive with the unit).
I received the new unit that claims Android 8.0 last week and had it installed today. So far, so good. However, I think its actually running 6.0 (based on a selection of icons offering me Marshmallow 6.0 option). The install went fine except for the canbus adapter I bought off Amazon did not work, so I've asked their support for help in what would allow me to use steering wheel controls. The mic they supplied has a cable that was only half as long as I needed to get up to my mirror, so its mounted on the dash and the clip is very small and wouldnt have worked anyways.
I've loaded up Nova Launcher with a bunch of widgets and installed Spotify, XM Radio, iHeartRadio, Pandora, Scanner Pro, Chamberlain MyQ, Swiftkey Keyboard, Transparent Weather and Waze. I am using a Personal Hotspot on an iPhone (AT&T) and a Galaxy S7 (Samsung). The location for time zone wouldnt pick up mine, it kept defaulting to China and I had to manually set them to my time zone.
Resolution is very sharp. It's pretty snappy and I've had no problems listening to whatever audio app I want while using Waze.
The unit did hang when I went through an area of bad cell coverage and had to be turned off and turned back on to get working again. I also noticed a slight wine through the radio that I believe is linked to the Live Wallpaper I was trying out. When I went to a blank screen, the noise went mostly away. I havent been able to get "Ok, Waze" to work yet (three finger tap works). I have yet to try Ok, Google. The unit boots quick after the first boot up (right away really, much faster than my Alpine unit in another car).
I installed this in a 2012 Ford F150 - I already have a rear camera in my rear view mirror, so I dont have one hooked up to the unit. I am using a powered JL subwoofer and separate Rockford Fosgate amp for my speakers. I do have a slight alternator whine when I have the volume turned all the way down.

Hey now! Researching for a friend that just decided to replace HU. Very interested - please keep reviews and details coming!
Couple questions for you now please?
1. Volume knob - responsive/no lag? (for the wife..)
2. FM radio reception is good? (also wife)
3. Aux video out (to headrest screens) - typical composite (yellow RCA) out?
3.1 All content to aux (ie mirrors the HU display) or only certain content/apps? (or can choose?)
And last question regarding tech support / Pumpkin
4. Do you have any experience with them and their tech support? Would you call them: awesome/great/ok/meh/****? Their support?
Thank you.

1. Yes, volume works, is responsive with no lag.
2. I only played a couple of stations, but no reception issues (when I was out of cell coverage, I switched to radio no issues)
3. There are two yellow RCA video outs (see product page)
3.1 I don't know the answer to this since I didn't use these features.
4. They are on a 12-hour clock from us, so answers are usually next morning and I've always gotten a response next business day. I would call it "better than expected:. I wrote about the missing ODB connector and they wrote to say its on the way.

Posted into Post #2 - I would be interested in what that tells us since I'm not familiar with the version numbers, although I know 4.4 is a KitKat kernel.

Great info man, thank you!
Hope you put up more experiences with it. Watching with great interest..

Overall, I am really enjoying this unit - its very responsive and the instant on is a great feature. The only thing I havent yet resolved is the 3-4 minute delay in connecting to an already powered on hotspot. Ive turned off notification of open wifis to see if that helps and will try turning off and on the hotspot. Basically I put an iPhone 8 Plus in the glove box with it plugged in for power so its running all the time - once a day I have to enable the hotspot, but its always on when I start the truck up. Just annoying it takes so long to connect to it.

quick question is the home screen customisable or are the icons and widgets fixed

You can customize the unit by using another launcher. Nova would be my first choice...

Correct, I switched right away to Nova (paid) as I use that on my phone. I've done just about everything I do on my phone here - widgets, etc.

Thank you for the update on this unit! I have an older model pumpkin stereo running 4.4 and it has gotten very laggy. I've tried factory resets to no avail (I'm using a customer ROM though). The lag is mostly on Google Maps (very slow to start and bring up navigation) and Pandora (plays okay but starts skipping near the end of songs).
I'm really thinking of upgrading to this unit. Since I had the older model, I bet I can just swap the head unit and keep all of the existing wiring. I really like the idea of the 1 second boot-up. With my current unit, it takes me at least 1-2 minutes to get music going (after boot-up, slow app startup, etc).
Can you tell me if Google Maps/navigation is okay? And Pandora?
Looks like the unit is avalable on AliExpress for $290:
https://www.aliexpress.com/store/pr...er-GPS-Navigation-4GB/612847_32853310272.html
It's even a little cheaper through their mobile app with coupons (about $281).

Google Maps is fine, although I am using Waze mostly. I will probably download an offline google map just for backup. I have Pandora installed, but have not yet used it - Spotify and XM Radio apps work as expected. I'll try out Pandora on my way home today and let you know.
If you can get it for $290, I'd say its a heck of a deal and worth the upgrade for sure.

It's an MTCD/E head unit, specifically a Klyde (KLD) PX5.
See relevant MTCD forums for all the info.

Pandora and iHeartRadio also work perfectly; no lag.
I'm still trying to get my iPhone hotspot to crank up quicker - strange that the unit can see WiFi all around me right away, but the iPhone takes longer to recognize. I'll try my Verizon S7 Edge to see if thats any different.

I have resolved the connection delay with my iPhone - it was an issue with the phone. I finally found a post that suggested having an apostrophe in the phone's name interfered with its discovery. When I removed it, the phone now picks up the hotspot wifi pretty quickly (starts connecting in seconds and obtains an IP).

Thank you for checking! I just ordered the unit from Aliexpress, got it for $281 after discounts.
Good to know about the wifi. I also tether my current stereo to my phone so it's good to know there are no issues with the head unit in that regard.
