r/Androidheadunits

Sorry guys I don’t know where to ask for my problem but if anyone know please help me

Dear Reddit Community,
I have been trying to troubleshoot it, but I have not been able to find the correct firmware or recovery procedure for this exact unit.
The head unit is installed in my 2013 Chevrolet Tahoe. It is an RM (RoadMaster) AN-1001 GMC Android head unit.
These are the details shown in Settings → About tablet:

Model: AN-1001 GMC
Android version: 4.4.4
Kernel: 3.0.36+
Build: rk3066-eng4.4.4 19092015...
CPU/platform: Rockchip RK3066
MCU version: MTCB-YZ-V2.80
S/N: 000D18A12539

The main problem is that the head unit constantly shows Google-related errors, including:
“Unfortunately, Google Play services has stopped”
“Unfortunately, Google has stopped”
“Unfortunately, Gmail has stopped”

Other Google applications also frequently crash
I tried to troubleshoot this through Settings → Apps, but I cannot uninstall or disable Google Play Services because it appears to be a system application.
I also have another serious problem: Factory Data Reset does not work. The reset option is not greyed out. I can press it normally, but absolutely nothing happens. It does not open the confirmation screen, reboot, or perform a reset.
I then discovered another error message on the unit:
“System UIDs Inconsistent”
It says:
“UIDs on the system are inconsistent, you need to wipe your data partition or your device will be unstable.”

This makes me suspect that the /data partition may be corrupted or that the Android installation has some kind of UID/permissions problem.
I am also wondering whether the unit may be rooted or running modified firmware. I have not intentionally rooted or modified it myself, as I purchased the vehicle with the head unit already installed.
I would like to know:
What is the correct recovery-mode key combination for this exact AN-1001 GMC / MTCB-YZ unit?
Is there an original recovery image available?
Is there an original or known-compatible firmware/update.img for this exact unit?
Is MTCB-YZ-V2.80 the correct MCU for this model?
Can I safely perform a wipe data/factory reset from recovery to fix the UID problem?
Is there a way to determine whether the unit is rooted?
If the firmware needs to be reinstalled, which exact firmware should I use? I do not want to flash an incompatible MTCB firmware and risk bricking the head unit or losing MCU/CANBUS functionality.
I have attached photos showing the head unit and the About Tablet information, including the AN-1001 GMC, RK3066, Android 4.4.4, and MTCB-YZ-V2.80 details, as well as the System UIDs Inconsistent error.
I would really appreciate any guidance you can provide, especially if you know the correct recovery procedure or have firmware/recovery files for this particular model.
Thank you very much for your help.

Hi, I am having trouble sorting the steering wheel controls for my android head unit. Its a raise renault 60 (pic included)
I think I have wired it correctly- I used the 20 pin connector in the base (also pics attached)

car: renault captur 2016, dynamique nav

I tried to get an image of the set up as best as I can

I just want to be able to change the volume with the steering wheel controls!

thank you in advance, any help would be appreciated =]

I connected my phone via USB, and my phone says that android auto is connected and all, but it shows this on my android unit, how i fix It?

Hi, the title pretty much sums it up. When I put my car in reverse I can see the camera and the parking sensors pop up but I just dont get any sound from them.

I recently installed a brand new Eonon E39X7S, their flagship and first Android 14 Head unit. After driving for the first ~5 minutes a seemingly random audio bug occured for the first time, before that the radio sounded absolutely perfect. Sometimes the radio recovers itself, sometimes it needs ignition to be switched off and on, and sometimes it even needs a hard reset with a thin needle.

I updated all the software and ofc wrote their support which seemed helpfull at first, but just left me hanging since last wednesday.

I attached a video of the issue. There is also a filter+fuse box that is part of the short iso radio harness, which I did not use as I had my original radio in the trunk and used Eonons own A0590 extension, which does not have this box at all. I am unsure if I should cut it out of the short harness and integrate it into the 6m one. The original BM54 radio module is still connected inside of the trunk to the four-wired quadlock connector that is part of the extension. The two 17 pin cables in the trunk are unused.

I also did a VIN decode and my car does not have HiFi, nor the DSP. So the resler stick + IBUS App does not fix this issue, eventho I am already planning on installing it, but only after the radio works properly.

On a side note, the parking sensor visualization and the speedo in the main menu of the HU does also not work and i already ordered a newer canbux-box with PDC supported. It should arrive any day now, but I do not expect it to fix the audio issue.

Hey everyone, hoping someone with auto electrical or aftermarket head unit experience can point me in the right direction.

I bought an Android replacement screen/head unit from AliExpress for my 2015 Mitsubishi Challenger. I’ve been trying to get it installed for a while but I can’t get the screen to turn on at all.

It came with a vehicle-specific harness and a CANBUS box. The seller is saying the cable they supplied might not be compatible with my car and suggested I take it to an auto electrician.

The part I’m confused about is that I tried to take the car’s wiring out of the equation and power the unit directly using the pinout they gave me.

I connected:

The screen still did absolutely nothing. No logo, backlight, sound or any sign that it was getting power.

I’ve also already had the seller send me a replacement screen and the second one is doing exactly the same thing, which is why I’m starting to wonder if there’s something I’m missing rather than both units being faulty.

The unit does come with a CANBUS box, so could that be the issue? Does the CANBUS box actually need to be connected for one of these units to boot, even if I’m feeding 12V directly to both B+ and ACC?

I’ll upload a video of the test as well as the pinout the seller provided.

Mainly I’m trying to work out whether my direct power test should have been enough to make the unit turn on, or whether these vehicle-specific Android units sometimes need another signal from the CANBUS box before they’ll wake up.

If anyone knows a good way to bench test one of these properly, or what voltages/signals I should check with a multimeter, I’d really appreciate the advice.

Thanks.

I have a 2016 Fit EX. It has the basic stereo with CD player. My son is about to get his licence and I want to replace the head unit with one that has android Auto to get the GOS into the in dash display so he doesn't get comfortable interacting with his phone while in the car. I know it isn't a perfect fix, but every barrier is better.(My bug fear is he starts taking video calls while driving. I feel like he's always on a video call).

Talking with him about it today he mentioned that having the map that low on the dash felt uncomfortable. His mom's car has the display that started co up above the dash, bringing it higher in field of view and I totally get that.

Is there a head unit that can accept a second display that I could mount on top of the dash?

The idea is to put it above these vents and get the phone off the window mount.

Thoughts, ideas, suggestions?

Hi, hoping someone can help. I replaced my Audi TT 2012 radio with a XTRONS android head unit and after installing it the audio keeps cutting in and out. Has anyone experienced this or know how to fix it please? Thanks

Hi everyone,

My Chinese Android head unit is not letting me turn the WiFi on at all; the switch just gets stuck.

The Bluetooth capabilities are also acting weird. I have to completely restart the head unit just for my phone to connect via Bluetooth. Because of this, Android Auto is not working, and it won't connect wirelessly either.

Could the WiFi/Bluetooth antenna be disconnected inside? Or is the actual WiFi/Bluetooth module damaged/cooked?

I appreciate any help or insight you can provide!

Here are my system specs for reference:

Platform/MCU: T100 Series (T13.1.1-100-10-A6939D-241125)

System Version: V13.1.1_20260408_OS-EN

OS: Android 10/11 (Spoofed as Android 15)

RAM/ROM: 2GB / 64GB

Hi all, I’m looking for some help with connecting SWC with a non canbus car. I tried to connect via the method given press start, hold steering wheel button, press desired control, then release steering wheel control. However, I keep getting the same study failed message I’ve tried to change so many setting. Can anyone help me? My car is a 2011 Toyota Yaris mk2. MCU information test revieled it does recognise the controls. But can’t get any luck. Any suggestions would be very grateful. Thanks!! Thank you

Hi zusammen!

Ich plane aktuell ein eigenes VehicleOS / Smart-Radio-System für mein Auto. Das Ziel: CB-Funk, klassisches Radio, Streaming, KI-Sprachassistentin und Fahrzeugdiagnose in einem einzigen 2-DIN-Gerät vereinen – ohne Armaturenbrett-Chaos.

Die gesamte Software schreibe ich nicht komplett per Hand, sondern entwickle sie praktisch ausschließlich im Pair-Programming mit Claude

Hier ist der aktuelle Plan:

💡 Geplante Features

* 🖥️ UI & Personalisierung: Widget-basierte Oberfläche mit speicherbaren Layouts, dynamischen Start-Begrüßungen, Multi-User-Profilen und Companion-App.

* 🎙️ Sprachassistentin (E.V.I.E.) & QoL: MCU-/Jarvis-inspirierte KI namens E.V.I.E. (Aufweckwort einfach kurz: "E.V.").

* Quality-of-Life: Sprachsteuerung für Fahrfunktionen & Medien, intelligente Erinnerungen (z. B. Tankstopp, Service), automatische Klima-/Lautstärkeregelung je nach Kontext.

* Diagnose & Sync: Speichert Fehlercode-Protokolle (DTCs) und synchronisiert sie automatisch im Heimnetzwerk mit dem PC/Laptop.

* 📻 Funk & Radio: CB-Funk + DAB+ / FM / AM + Internetradio. Antennen-Setup über maximal 2 Antennen (OEM-Antenne per Splitter + 3-in-1 LTE/GPS/Satellit-Kombi). CB-Handmikrofon wird auch für Telefonie genutzt.

* 🛰️ Satellit & Notfall: Integriertes Satelliten-Modul (RockBLOCK/Iridium) für SMS-Notfallnachrichten ohne Handynetz.

* 🎵 Media & Ducking: Streaming (Spotify, YouTube, Netflix etc.) mit automatischem Audio-Ducking bei Navi-Ansagen oder CB-Funk-Sprüchen. Ausgabe über die Auto-Lautsprecher.

* 🚗 Fahrzeugdaten & Sicherheit: Trip-Computer mit Live-Telemetrie (OBD-II/CAN-Bus) und Blitzerwarner-Integration (Oooono). Modular als 2-DIN-Gerät konzipiert.

🛠️ Hardware-Setup

* Hauptrechner: Raspberry Pi 5 (8GB) + M.2 NVMe SSD

* Display: 7"–10" Kapazitiver IPS-Touchscreen

* Audio & Radio: HiFiBerry DAC2 HD + RTL-SDR v4 USB-Dongle

* Fahrzeug-Schnittstelle: MCP2515 CAN-Bus Modul / OBDLink SX

❓ Fragen an die Community

* Machbarkeit: Wie realistisch ist dieser Feature-Umfang auf einem einzelnen Raspberry Pi 5?

* LLM / Prompt-Coding: Hat jemand Erfahrung damit, so komplexe Linux-Audio-/SDR-Architekturen fast ausschließlich mit KI (Claude) zu generieren? Worauf muss man bei Hardware-Schnittstellen besonders achten?

* Audio-Routing: Habt ihr Empfehlungen für sauberes Audio-Ducking unter Linux (SDR-Funk vs. Medien-Streams)?

* Car-PC Basics: Welche Stolperfallen bezüglich Stromversorgung (Safe Shutdown bei Zündung aus) und CAN-Bus-Stabilität sollte ich dringend beachten?

Freue mich auf eure Tipps und Feedback! 🙌

I bought this unit on Amazon and everything works and installed easily on my Nissan Altima

The only thing I can't figure out is how to stop this screen from loading every time I turn the radio on. I've searched through all the settings and found logo settings but this wasn't available. This same screen comes up when I use the help app from the home screen. Seems like the help app is loading on startup.

Update: Solved! It did turn out to be the help app I just had to disable the app. Thanks everyone!
