Head Unit Security

I'm about to pull the trigger and get one of these head units for a car I haven't purchased yet! Can anyone comment on the security of them? I've heard of some security issues for inexpensive chinese android devices recently.
Thanks!

Do you mean security as in software hacking or security as in people smashing windows and stealing devices?

LOL.
Security ? Forget about it... Same for any Android device and moreso for Chinese, if for no other reason than security costs money and China sells cheap cheap.
What worries you ?
Wife/GF finding out where you've been ?
Google tracking you ?
NSA,... ?

You're not going to be storing any personal info in your car headunit anyway, probably just music and a nav app. Nothing to worry about.

The thing is, I get almost all of my music through Amazon Prime, so I'll have that account information linked to the head unit.

You could always connect your phone to the headunit via bluetooth and run the Amazon Prime Music app on your phone.
I do that sometimes with I heart radio to view the song info on the phone screen and use waze on the headunit screen.

but that's the whole purpose of putting a mobile OS into the dash, so I don't have to use my phone.

My phone and hu go hand in hand. I connect my phone & hu with bluetooth to get calls and messages on my hu. I use the phone's 4G LTE as a hotspot to provide wifi to the hu.

of course, but using apps on my phone defeats the purpose of having an android head unit. Otherwise, I would just keep using my phone mounted to my dash.

If you're really worried i would download something like avast mobile security, and maybe setup 2fa on your accounts. I think it highly unlikely that these headunits come preinstalled with keyloggers or something. These companies may not be known for their QA, but that doesn't mean they are outright criminals after your data.

Thinking about the initial poster's question in the context of physically stealing the headunit. I'm using traccar, but that only helps me find the device once it's online again. I can remote wipe it with google device manger, but what are others using for mitigation in the time between someone stealing the headunit & the owner finding out? The other scenario is car valets - how could I keep them from accessing all my data? Any thoughts?

Download an app like Avast Mobile Security to encrypt and protect
your data. That and I wouldn't recommend using your HU as a repository for sensitive data. But that's just me.
Of course, if someone stole your HU they would probably just do a factory reset and all your data would be lost.

The data I'm worried about is related to the fact that I'm logged into google on my headunit & real damage could be done from that alone. Thanks for the suggestion. I've found a couple of apps that'll help me lock it down right.

This concerns me too. I'm about to install an Android head unit in my car it will be connected to my Google account so that I can stream music from Google Play. Am I correct that there is no lock screen for these units?
@tylast: what apps did you find that might be helpful?

I have the same concerns. I would like some sort of password protection at boot. I hear it is possible by installing Tasker and Secure Settings.
As a workaround, I've fitted a hidden power switch in my car that cuts the ACC power to the HU.

I settled on AppLock 2.

Is there really no way to lock these devices at boot?

TC Car Audio Android Head Units

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.

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.

Android Head Unit - Assistance Required with Google Music Music Next/Previous Buttons

Hi All,
Recently purchased and installed a Joying head unit (4GB, PX5 Octa Core) (link to product)
I use google music for all my music needs. I have uploaded all my personal music onto the google music cloud servers so I can stream or download them whenever I want making it an ideal solution. I installed the google music app on my android head unit and everything works great appear from one small thing.
The steering wheel NEXT and PREVIOUS buttons are not responding on the music app. Its killing me cause at the moment every time I have to change a song ive got to touch the screen (not ideal when driving).
Volume buttons work fine but ive tried different things to try and get the other buttons to work within the app like button re mappers via the app store etc.
Does anyone know of any way to get the NEXT and PREVIOUS song wheel buttons to work with the google music app. I will love you so much
I think its a software thing with the app cause poweramp and some other music players work with the wheel buttons. If this is the case I was hoping that there is an app that can run in the background which can pickup the wheel buttons and translate them so they work with the google music app.
Any assistance would be great. I hope someone can help.

Bump. There has to be a way around this.

Bump again. Really hoping there is a solution. If not can anyone recommend another forum/discussion board to try.

Type of car, type of CANBUS adapter if any, would be helpful. Because to me it sounds like a problem on the car side, not the app side.
Tried using the forward/back buttons on a different app or via Bluetooth pairing?

Car is Toyota Aurion/Camry.
So as in original post I can confirm it works on other apps such as poweramp and even the stock bluetooth player but on google music its not working. Im pretty sure its a google music app issue but im hoping there is a work around.

Bump. Please help

I have a same problem. The Next & Previous button does work with stock music and radio though but not with downloaded apps. Either it Spotify, Google Music, PowerAmp, VLC or AIMP. The Volume button working fine though. Appreciate if anyone have a solution.
Thank you in advance.

Seems like those controls are only directed into built-in media apps (radio etc). I found an app to translate the signal to universal: https://play.google.com/store/apps/details?id=com.petrows.mtcservice&hl=en_CA

Junsun Android 8.1 Intel Airmont eight-core 1.8GHz SC9853i (4GB RAM, 64GB flash)

Since there are threads for Joying, Teyes, FunRover and etc, I think there should be one for Junsun as well.
I bought a Junsun V1 4G+64G "Android 9.0" (Android 8.1) DSP Car Radio Multimedia Player For Suzuki Swift Sport 2010 to replaced my aged AN-21U [url]https://forum.xda-developers.com/showthread.php?t=2528349[/URL] but I am quite disappointed with the sound quality, especially the radio tuner sound and reception.
The Intel eight cores performance is great compared to the old 2 cores and 64 GB storage is plentiful but the sound isn't even close to the AN-21U even though it has DSP.
The radio tuner sounds mono when it indicates stereo, switching to mono sounds exactly the same. Auto scan comes out with zero stations. I will try to get a FM signal amplifier to see if it helps.
The RCA cable did not have an input for external mic. I asked the seller and he said there has been a upgrade with the sensitivity of the internal mic and this version don't support external mic. The internal mic has work satisfactory so far for voice commands and calls.
I used TuneIn radio to replace the lousy FM tuner but it was only marginally better. I replaced it with Poweramp internet radio streams and I have a winner. Unfortunately, Poweramp doesn't support Google music.
For that, you will need USB audio player pro. It sounds better than Youtube music and also support Tidal, Qobuz, Shoutcast, DLNA server and internet radio streams.

Rooting
Tried out the rooting method post at https://forum.xda-developers.com/showpost.php?p=82485735&postcount=228 and it will indeed cause problem with voice navigation for Google Maps, Waze and Google Assistant. Sygic was ok, perhaps it doesn't required Google TTS. Someone complains problem with PlayStore too but I didn't test it and un-rooted by restoring the original boot image.

Hi!
I have the same model. And I ask some things on other thread.
https://forum.xda-developers.com/showthread.php?p=83085985
Do you have any recommendations? firmware update files?
Maybe we can use his thread to apps recommendations, solve typical problems and more.
We have different Bluetooth version.
And do you have the update to enhance the mic?

The radio tuner sounds mono when it indicates stereo, switching to mono sounds exactly the same. Auto scan comes out with zero stations. I will try to get a FM signal amplifier to see if it helps.
The RCA cable did not have an input for external mic. I asked the seller and he said there has been a upgrade with the sensitivity of the internal mic and this version don't support external mic. The internal mic has work satisfactory so far for voice commands and calls.

Just one more question.
Did you try different launcher like AGAMA or others?
And, dou you know how to change "Google voice search" to "Google Assistant"?
Thank you!!

I had asked twice before the seller was willing to send an link to the "latest" firmware (I'll post it & other resource collected in the OP) but I haven't tried it cause it looks older than what the unit came with.
@eXPerience1983, what problem is the mcu file from the seller suppose to solve?
I'm still using the default launcher so last used app will start since I'm using turn off to sleep power scheme. I'm looking to try Car Launcher FREE https://play.google.com/store/apps/details?id=com.autolauncher.motorcar.free&hl=en-GB, has ability to enable/disable voice command button and choose between Google now, Google assistant and Alisa yandex. There also ability to start chosen audio player when the launcher starts.
Have you tried tasker?
If I remember correctly, Google Assistant was installed/updated during initial boot-up Google apps updates, mine don't have Google Now preinstalled. It works fine with app start, app search and etc, only voice calling needs to click call after it finds the contact and number.
I'm not sure if it's really a updated unit which don't support external mic or improved mic that the seller
explained or just excuse for RCA cable without mic input but it works fine for voice command and calls (I have ordered a similar RCA cable with mic input from China to test later). If the mic is indeed improved, it's probably be a hardware change.

I was about to embark onto USB audio and DSD to an external DAC because of the poor FM reception and sound quality, my research runs into apps like USB audio player pro, Neutron music player, Onkyo hf player and Poweramp.
Poweramp makes the sound much fuller and the internet radio stream has solved my bad reception problem, much faster streaming and better sound than tunein radio app. I bought the pro version and fully enjoys it (I have no affiliation with the app).

I don't know what it's supposed to solve. I'll attach the file here. But have no info or instructions (they only say "insert on the radio and restart it") and I'm not responsible of any possible break.
And about Poweramp, I bought the pro version a few years ago but I don't use it for a long time. I never used it to FM streams, and I suppose that you need to find and manually add the address to the stream list. I have TuneIn Radio Pro but I usually use Spotify.
I see some mods for FM, but not sure which one is valid for us. And here, in Spain we haven't Digital radio so I can't use DAC.
I think I'll try another launcher, maybe AGAMA because it's free for 30 days. And looks very well, it seems to be possible to autostart some apps with it.
About Tasker, I don't buy it yet. And some apps don't autostart services (like Blockada). So I don't know what can I do with it and if it will work to start apps or change Voice search to Google Assistant.
If anyone finds how to change the wheel buttons to start Google Assistant, please share it.
About Navigation. It doesn't have magnetic or acceleration sensors to help GPS, but GPS works OK (but Radardroid can't use the option to autostart at drive because we don't have the acceleration sensor). Only receive GPS and GLONASS, not received any BEIDU or GALILEO signals.
I use Android Auto to easily use Google Maps and Spotify into the same interface. But I need to start Spotify before or Android auto can't start it. To offline GPS I use Here WeGO because I have sound problems with iGO Navigation, but didn't tested too much.
How do you share files between your mobile and radio? I'm going to try the app "Send files to TV" because the Bluetooth doesn't find my phone to send it.
I know I have to enable "OBD2" to use Torque app, I have both but can't try it yet.
Ah, highly recommended!!!
Turn on the "LOUD" setting under General Settings -> Sound. Music sounds much better, don't you think?
I'll share more details about the radio when I use it more. I only have it one week.
Seller send me this for my Junsun V1 PRO 4GB/64GB WIFI + 4G but I didn't use it

Bluetooth/Zlink
Hi all,
I’m abit of android noob.
My unit have the same specs as list above. Does anyone experience Bluetooth phone calls quite unclear? If so, what did you do to rectify it?
Bluetooth version: BLINK_2161_RELEASE0/2020:06:2:17:41:29_blink
Is there another Bluetooth app you can use?
Also the unit came with ZLINK for Apple CarPlay, I find it sometime dropping out and not connecting. Can anyone shed some light on this?
Any help would be much appreciated!
Thank you!

My bluetooth version is older than yours. But, for the moment, works fine.
BLINK_2161_RELEASE0/2019:12:30:11:43:58_blink
And I don't have an iPhone to test that app.

He mentioned “Android 9.0” Android 8.1 at the beginning.

It shows Android 9, but it's really API 27, Android 8.1.

Try CPU-Z https://play.google.com/store/apps/details?id=com.cpuid.cpu_z, system tab should tell you the Android version and API level.

I believe a buyer feels mislead about the Android version (8.1 advertised as 9) and the DSP difference between 2/32GB and 4/64GB units (software DSP versus hardware DSP) and different amplifier chips TDA7851 versus Toshiba TCB001HQ.

I solved the problem of apps that doesn't autostart.
Example:
Blockada
Radardroid
Spotify
I used this manual:
https://4pda.ru/forum/index.php?showtopic=936715&view=findpost&p=89407921
With this app:
https://play.google.com/store/apps/details?id=com.james.SmartUninstaller
Spotify, blockada and Radardroid works fine now with a restart, but no on wake-up.
Maybe because I didn't activate them at secondary autostart. But need to test it.

I'll add more info and some recommendations for Junsun V1 PRO.
For better sound:
Goto "Settings->System->Sound-> Enable LOUD"
APPS:
Smart App Manager - To allow apps to autostart services or the app itself:
https://play.google.com/store/apps/details?id=com.james.SmartUninstaller
Instructions from here: https://4pda.ru/forum/index.php?showtopic=936715&view=findpost&p=89407921
-Go to "System Info" in the menu.
-Press the "Battery Usage" button.
-"Startup Management".
-"Applications, autorun". This enables autostart at full reboot.
-"Applications, secondary launch", not tested yet bus its supposed to enable autostart at wakeup.
UPDATE:
-"Application standby optimizer", enter on selected apps an disable the optimization.
UPDATE 2: OK, most of time apps don't restart after disconnect the car for long time. But background services do, so you can activate them easier.
Example:
-Radardroid can be activated via widget.
-Blockada can be activated via widget.
-Spotify can be activated/accessed via Android Auto.
UPDATE 3
After wake up it still closing apps. So I disconnect the "Application standby optimizer".
I only keep activated some apps on "Applications, autorun" and "Applications, secondary launch". They start at full reboot and seems to keep services running after wake up.
Blockada - If you want to efficiently block ads, trackers, malware, save on your data plan, speed up your device and protect your privacy with just one application, then Blokada is for you. It is free, secure and open source.

@eXPerience1983, did it work when you activate it at secondary autostart?

No, it's valid for a quick reboot. But, if the car is turned off for a few hours, apps don't start again.
Need to investigate more.
Att 4pda says something about "Application standby optimizer".
I'm going to try and test it.
Edit: for now it seems to work OK.
@gpmg762 the seller send me the same firmware than yours and another file with a video and almost empty file. Plus the .bin that I posted a few days ago.
Did you try the firmware update that you post on the first message?

I doubt selller wants to support firmware update and gives the same link to everyone who asked. I havn't tried the given firmware since i don't want to end-up with something older.

A 4pda user reports a 3 months old Junsun V1 Pro 4 + 64 Gb goes up in smoke, https://4pda.ru/forum/index.php?showtopic=938749&st=6040#entry98401021. I wonder if it overheated. I have already attached a fan and use acc power to cool it below 60c.
