ZX803 model AllWinner chip 8" Android 4 capacitive screen car head unit

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.
Now it looks like this:
Thanks!

Could you post a link to the stock radio app. I have the S150 Head unit:
http://forum.xda-developers.com/showthread.php?t=2503964
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.

I don't think it is compatible, it's a totally different system. I can't post outside links being a newbie, but drop me your email adress in PM.

Hello everyone, I also purchased a zx803 unit for toyota corolla model.
The same specs that stanjkof wrote.
I would like to exchange info and ideas to improve this unit.
Stanjkof, I dont know what hidden menu you say, I flashed firmwares several times and I never saw that menu.
If you dont have a little hole to reset unit, you can use any app to restart from google play.
Your radio app mod looks nice, well done!. Can you share it?

Hello, drop me an email in private message, I will send it to you via email (I still can't post external links here).
Are you satisfied with the unit? i guess they have some quirks but overall I like it.
I found that Poweramp is the best player for car unit regarding sound quality, album art and so on.

You have over ten posts now, so you should be able to post URLs. Besides, you could have encapsulated URLs with an underscore (_) in order to post links. For example, _http://www.google.com_ and it will bypass the forum's parser that checks and replaces it with a clickable link or prevents you from posting if you have < 10 posts.
On a sidenote is there anyone here that can do me a favor and please install Android System Info. Click on the "System" tab, click on the application (overflow) menu and export results to file. Go through it, its a simple html file in /mnt/sdcard directory and censor any information that want to hide like accounts names and SSID then upload it as an attachment. I'd like to open a dedicated Wiki page for this unit and that way you can have a place for FAQs and such.

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?

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....

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.

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.

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.

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.

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

I think you forgot to write your question or complaint about your cheap chinese car radio.

Pretty much what I am looking at just a universal double din.

Ask for this unit
I want to ask for this unit have a equalaizer and how band if have and have a sub woofer control level.?anyone know something because the official company don't know hi hi:Π

Yes have a equalaized band FM ,AM

Thank u for ur reply but me I ask is not for this band am fm but the equaliser band areas and the other questions is have a sub control level me old unit eonon ga6153f have this u know to tell me? Thanks.

I have this unit installed and yes, it has a software equalizer. It's 9 band with subwoofer control.
Does anyone have any issues connecting the head unit to their phone's WiFi hotspot?

Did a firmware update which was provided by Xtrons support, and also there's an issue with Tasker if you have Tasker automatically start your hotspot when it detects your phone connecting to the unit's bluetooth. You need to install an additional Tasker plugin to fix this, it's called "Nougat+ Tasker Tethering Control".

I have the same unit. Is there a way to prevent all apps from closing when the unit goes into sleep mode?

I think I will put all apps I want to run on startup on the first tab then. Even tasker doesn't boot at startup/wake up.
Which firmware do you run now?

How good is this unit?
Pros and cons?
I'm thinking on putting this one on a LEON MK2 2007

I am pretty glad about this unit. Android has so much more options and capabilities than my older RNS510 unit.
Some cons that I have experienced is that the unit sometimes restarts itself. I am not sure yet what causes that.
And sometimes when I open multiple apps in a short period of time the unit freezes. The only way I got it to restart is to push the power button for +- 10 seconds.
In the 1 or 2 months that I have this unit, this only occcured 2 or 3 times.
One small little thing is that I wanted to use TomTom Navigation but the 3D view shows a blanco map with only the street names. So I just use Google Maps now.
And I found it very hard to get a decent reception with the DAB+ Antenna from Xtrons.
Overall I am glad with the unit. It is definitely an upgrade compared to my older version of the RNS510.
This unit responds very quickly and has a lot of options.
Let us know what your choice will be!

I'm thinking of getting one of these. What is the boot time?

If you really want to improve your DAB+ you got to find your antenna amplifier in your car and it should look like this... https://www.kufatec.de/shop/media/images/popup/DAB-Antennensplitter-fuer-VW-Golf-7.jpg it fits almost in every Volkswagen/Audi/Seat or Skoda
If so, you have to swap your FM amplifier with a DAB+/FM amplifier, i know Calearo ain't cheap but is european made and it works really well in my car, and i had to install a sharkfin antenna to receive DAB+ and GPS because i had no other option. (sorry for the many adjusted posts, technical problems)

Want to upgrade my android 4.4 MTCB - I use Tomtom as navigation. The PB88UNVP is interesting as is had 4GB RAM. I've read android 8 units have problems with the 3D navigation of Tomtom. Is there a known fix for Tomtom, or is it possible to install Android 7 on this device (don't know if there's a (custom) ROM that works with this device).

ok, got a PB88UNVP. Tomtom - no 3D navigation. Will use an other navigation app.
Unit works fine, but the WIFI connection is not reliable. When waking up, the unit tries to connect to a access point. Sometimes that functions without any problems, but other times it doesn't find any access points (while I know there are). Turning wifi on or off does not help. From time to time, the wifi can't be turned on or off (seems to be frozen on the on/off toggle switch).
I like the unit, bit the wifi problem is a big problem for me. Is this a known bug / problem with this or other devices?

yes getting the same problem on Xtrons PE88jccpl (Android 8, Octa Core) sometimes the wifi connects perfectly but other times getting authenticating, authentication errors. Also, having problems with the speed when its connected it starts out fast and perfect but slows down to .2 to .3 mbps after a couple of minutes. Xtrons support sent me a link to update and I updated both MCU and android but still getting issues. (I put the img and update.zip on a usb stick and once I inserted it asked if I wanted to update) Not sure if I am supposed to wipe the device after updating android

Thanks for your reaction. I also received the download link for this update. MCU 2.88_3 and Android image with build date 20180703.
I installed this update this morning. Checked the wipe everything' option to be sure to have a clean install.
Had the wifi not connecting 2 times today with the new update
I've not noticed the speed collapsing. I did download navigation maps (couple of GB) without problems. When the Wifi does function it functions well, the next time the system wakes up from sleep it's an about 50% chance it functions.

Have you tried downloading the speed test app to test?

Hizpo Ultraocta t8 android 7.1.2 review and UPDATE questions

Hello Developers
First, I hope you are all safe!
I bought this HU from amazon, three month ago. It seemed to me to be a nice radio, but I shortly realized all the problems that these systems are bringing us.
Pros: for a basic user, works pretty fine, you listen music, watch videos, backup cam, rear monitors, 4g, wifi, bluetooth, touch screen. Just like a regular android system.
Cons: Bluetooth only connects to phones. Rear monitors don´t mirror HU, just external videos (usb, dvd, sd), extra settings codes NOT PROVIDED by tech support. I found 10x more helpful this forum rather than waiting 48 hours for a poorly written answer. JBL harness is just a mess. Sound quality is HORRIBLE. Im very picky (musician). the steering wheel works partially, just Volume Up/Down.
SO.... Now I would like to update the OS, my goal here is to be able to connect my cobra iradar by bluetooth, try to mirror the HU to my rear monitors and hopefully make this right!
SPECS
processor: ULTRAOCTA T8
android: 7.1.2
MCU: 5.3.19-123-10-E06101-171205
System version: V9.2.2_20180523.142211_ZYC2-FD
2GB RAM
32 ROM
questions:
Do you think an update might work? would improve anything?
Im already planning getting something else in case this doesnt work, but all this generic radios´android system are so messy and the specs the sellers provide are just not trustworthy...So if you could give me any advice that would be amazing!!!
UPDATE
How to mirror? Ok guys, so I figure it out how to mirror, now if not 100% mirroring but it is showing a path...
While watching a video, press home, now is minimized, like a small window and that´s the trick. Now rear monitor are mirroring, but this includes the video...
I guess it is obvious that this is not a hardware issue, but just a OS issue.
Again, It would be wonderful is you guys could give me some input on what specific files should I use in order to upgrade my OS and maybe getting the job done.
Thanks and stay safe!
Pablo

Hey guys!
I hope you all safe, maybe someone can help!
thanks

thanks for reply... I was thinking buying a 300 dollars new gear from aliexpress but it´ll be the same. It is not a bad radio overall, just all these annoying details...but the lack of support out of hizpo, it is awful...1 star max!!!

update on video output:
It does output headunit´s screen to the resthead monitors. you got to load the video first and then it will mirror everything on the back.
I tried 2 4g dongles. BOTH WORKED but not even great.
ZTE MF833V worked after closing the download mode. I used DC unlocker, extremely easy.
It connected at ATT network , 3g (with logo) and 9-12 megs per seconds download. I could not reach 4g although I was able with my laptop. So i think it is a android issue.
Huawei E3372H-153, it did not actually connect, but I think it was my fault because I did not set the APN. But I was able to check my host settings via web interface. Also, it is a little messy with USA networks but NO CHANGE needed. Which is cool!
Thanks for all the info around this place!

2 days ago, volume and knobs stop working, steering wheel controls not operating, although I have touchscreen. I have not been able to restore it. It loaded once correctly, but 30 mins later it broke down again. Same problem, some settings works and some not.
I´ve tried to factory reset (code 7890) but it does nothing. So, I am trying to Hard reset. I haven´t found a solution yet, Im gonna be pressing RST buttom for a weekend figuring out the sequence.
If you can help me getting RECOVERY MODE, it would be really appreaciated
I will update
Stay safe y'all
