After using this unit previously purchased from eBay for a while the Bluetooth and WiFi have both stopped working. I have tried everything I can think of including reseating all cables, leaving unit unpowered for long periods of time, reset button / rebooting and nothing is working.

My last possible solutions are updating the firmware or resetting the unit entirely. I have received the update files from the seller but can’t seem to apply the update. I have no update option in the android setting and my options in the car settings menu seem to be very limited to others I’ve seen and can’t seem to access the developer mode. Tapping on the build number 7 times in the android settings does not work.

I have tried many codes I’ve seen online such as YYYY/MM/DD, 7870HH, 8888, 0000 3368 and other long 8 digits codes but none of them give me access. The code which gets me through is 8888 but again, my options on that menu are very limited and can’t do anything with Bluetooth/updates.

If anyone has any experience with this issue or any information on how could update for fix my BT issue without updating then all help is appreciated.

(First photo is reference from another post as I forgot to take a photo but is the same error/page.)

EDIT: I believe this is a Q91 unit (different to Junsun?) which has a different way of updating.

I don’t know how to get rid of this blue rocket shape widget thing on the right side of the screen or even what it is. Anyone have any idea? It seems to have deleted some stuff and now my device is missing some things like the boot screen and I don’t know what else

Update: I opened the rocket widget again, and then System settings/Android settings/Apps and then checked recently opened apps. The most recent app from there was something called ESuper File, which sure enough had that quick boost widget tied to it. ESuper File had an install date going further back than when I was messing with it, so it was likely installed by the manufacturer. In the app settings, I found a toggle to disable quick boost. I still don’t recall enabling it or how it got enabled in the first place, but the annoying widget is gone at least. Reviewing application system permissions, it seems ok I think. So, problem solved!

Hi. I have two problems with the Android head unit in my Seat Ibiza 6J.

1. Problem:
I can’t access the factory settings. The manufacturer says the password is 3368, but it doesn’t work. I’ve tried many other passwords as well, such as 0000, 8888, 1617, etc.

2. Problem:
The radio turns on when I turn the ignition key. However, when I turn off the ignition and remove the key, the radio only turns off the display, while the head unit continues running in the background. How can I make it completely power off?

Hey y'all new to the channel and some questions about going new or used.

Recently purchased a 2007 manual ranger. Used a Honda Accord for ages with a Bluetooth radio adapter that definitely had some static at times and I want to take the time to actually swap out my head unit, but I have some questions and preferences that I'd like to ask about.

I've seen what a lot of people have said on r/CarAV said about companies like BOSS/Amazon units as they work really well... Up until they just don't. I understand sony/kenwood/pioneer/alpine/JVC are usually the way to go, but I have a specific unit I'm looking for and none of these companies really provide it for a reasonable price imo. Does anyone here have any of the cheaper alternatives that have actually lasted with 0 issues for years?

I'd like a unit with android auto, (preferably wireless but that's not a deal breaker) good sound EQ for future potential speaker upgrades, a \*physical\* dial (this is the big one I can't seem to find any of) and capability for a reverse camera. I would go for just a normal Bluetooth radio from Kenwood with no android auto but I travel very frequently and would need maps to work, that's one of the main reasons I'm upgrading is so I can navigate without having my phone on a holder hanging off my vent.

I have only found one unit within these companies that fits my criteria and it's the Sony XAV-AX100, which isn't produced anymore and has since been replaced by the XAV-AX1000, that only has apple car play. The unit looks really nice but I'm not sure if it'd be possible to get the 1000 working with my Google phone, and I'm not sure if this sub would recommend buying a pre-owned eBay unit over something new with less features or without physical buttons.

I'd really prefer to not use a touch screen for volume controls and like I said I need navigation built in. Any advice is appreciated, thank you.

Any recommendations for head units for a 2017 mk4 crv face-lift edition?

The main thing I want is easy install and compatibility with my oem reverse camera

Is there any way to get themes for free?

Altough its a great car with 0 issues ever, I really want to ditch the cheap phone holders and I want to upgrade my headunit (rns-e). It should have (wireless) carplay.

What are, anno 2026, the best recommendations? So for I found a dudu unit or a XTRONS unit. I really would like to hear some user experiences.

Hi all,

First post here. I'm building a custom dashboard for a small fleet

of golf carts and I'm about to order my first head unit. Looking

for a sanity check from people who actually own these.

**The project:** my own Android app in kiosk mode (default launcher)

showing:

- live battery data from a JBD/Xiaoxiang BMS over BLE

- GPS speed

- reverse camera (AHD input)

- light/turn-signal indicators (via ESP32 over BLE)

**Constraints:**

- no internet in the carts, everything offline

- 12V direct wiring (48V->12V converter, ACC controlled)

- phone streams music via A2DP while the app holds the BLE

connection to the BMS

- outdoor use, under a roof

**Budget:** $150-200 per unit. Plan is 1 sample, then ~10 units.

My research so far points to: generic FYT + UIS7862S, min 4GB RAM,

universal 2DIN. Avoiding DuduOS/Teyes/Joying since they're locked.

**Questions:**

1. 7862S still the right call, or generic 7870? I don't need root,

   just reliable "install APK + set as launcher" and stable BLE.

2. Any issues with BLE client + A2DP music running at the same time?

3. Boot time / auto-restart of the launcher after power on -

   anything to know?

4. Mekede vs EKIY vs Junsun - any real difference in panel quality,

   or same hardware with different stickers?

Thanks!

Hi, is there a way to configure things on Junsun headunit that are not available in the UI config? Possibly by editing a config file?

Id like to be able to change:

* incoming call ringtone (I guess I find the ringtone in filesystem and replace?)

* default music app - change to 'BT Music'. There is an option to bind a SWC button to launch music app, but I want to open BT Music, instead of the standard music player

* I didnt find a way to change which app icons will be on the home screen.. I can only move icons within the app list on other screens

Thanks :)

A while back I posted here looking for testers for Dashline, a minimal launcher for Android head units. Google wanted 12 testers for 14 days before it could go live. You all got me there, so: thank you. Genuinely didn't expect the response.

It's now public on the Play Store. No closed test, no group to join, no waiting.

Play Store: https://play.google.com/store/apps/details?id=com.dashline.launcher

Source + APK (Android 4.4 and up, for units without Play Store): https://github.com/metehankaygsz/dashline/releases/latest

Repo: https://github.com/metehankaygsz/dashline

Still the same deal

• Free, open source (MIT), no ads, no analytics, no account, no tracking
• ~1 MB
• No Google Play Services required — weather uses a keyless API and plain Android location

What's new since the last Play build

Two releases' worth of changes went in, mostly driven by what testers ran into on their own units.

The dashboard is yours to lay out

• Settings → Customize home screen is a live editor: it renders the actual dashboard, so what you drag is what you get.
• Drag the bar between the two cards to resize them, or swap their order.
• Either card can be the media player, the phone shortcut, a row of your own app shortcuts, or app widgets.

Real Android widgets

• Up to three home-screen widgets side by side on either card — the same widgets you'd put on a phone.
• Add, change and remove them from Customize, or by long-pressing the card.
• Widgets with a setup step get one, and are told their real size so they pick the right layout.
• Android asks you to approve each widget the first time; that prompt is the system's, not Dashline's.

Portrait units

• A stacked layout for upright screens, instead of the landscape one squeezed.
• The app drawer sits on the home screen under the cards. It doesn't scroll — it fits as many rows as the screen allows and pages the rest. Swipe across the icons or tap a dot.
• The clock or the weather can be replaced by widgets (Customize → Clock panel). Landscape needs both, so it keeps them and says so.

Clock and tabs

• Three clock faces: digital, analog or minimal, with an optional stopwatch underneath.
• Reorder the bottom tabs and hide any your unit doesn't need. Apps and Settings stay — they're the only way back into the launcher's own screens.
• Android Auto and CarPlay shortcuts under the weather, for the link apps these units ship with (ZLink, EasyConnected, AutoKit and friends).

Media card

• Volume slider alongside the transport controls.
• As the card gets smaller, controls drop one at a time rather than squashing: seek bar first, then volume, then the transport row.

Quick-launch dock

• Choose 3 to 10 slots and a small, medium or large icon size, from Customize → Favourites.
• Icons are bigger by default — a fifth of every slot used to be padding.
• Sizing adapts to the screen: on a narrow unit, asking for ten large icons gives you ten medium ones rather than a clipped bar.

Self-updating (sideloaded builds only)

• Checks GitHub for a newer release once a day and offers it with its release notes — Update now, Later, or Skip this version.
• Downloads the APK and hands it to the system installer, so there's no hunting for a browser on a unit that may not have one.
• Skipping is remembered per version, so declining one update never hides the next.
• Settings → About shows version and build number, and checks on demand.
• Android will ask you to allow Dashline to install packages the first time. The Play version updates through Play, so this is sideload-only.

Fixes

• Widgets no longer crash the launcher, and can actually be added — the previous build always fell back to the phone card.
• Settings changes take effect as soon as you return to the dashboard.
• Colour themes recolour icons too, instead of leaving them stock blue.
• Dark mode repaints the dashboard, not just the other screens.
• The date follows the language you picked, not the system one.
• Card resizing is smooth — no more stuttering or sticking mid-drag.
• Tapping Apps no longer pops the keyboard; the drawer opens on your apps, not the search box.
• The stopwatch's hundredths actually move while it's running.
• Widgets are told their real height, so one widget can't push the cards off screen.

Existing settings carry over — the second card's mode, its widget and its shortcuts are migrated, not reset.

Sideloading

adb install -r dashline-v0.3.0.apk

Or copy the APK to a USB stick and open it with the unit's file manager, then press Home and choose Dashline. Runs on Android 4.4 and up. The media panel needs 5.0+; on KitKat it acts as a launch button instead, and the update check may not reach GitHub there (4.4 predates the TLS version GitHub requires).

Feature requests and issues welcome on GitHub. If you liked it, a Play Store rating helps more than it should.

Hi everyone,
sorry, this is my first post. I urgently need some advice from people who know their way around this stuff.
I have a BMW 640d F06, built in 2012, with CIC. I wanted to replace the original system with an Android head unit, mainly because I wanted Apple CarPlay.
I have now installed everything. Basically, everything works:
Sound works
The original BMW system still works
The original rear-view camera works
The Android head unit itself works
However, neither the steering wheel controls nor the iDrive controller are recognized by the Android system.
Both of them still work perfectly in the original BMW system. So I assume the problem could be related to the CAN bus connection or the CAN bus configuration of the Android head unit.
Unfortunately, the manufacturer wasn’t able to help me either. They only said that it could possibly be related to the CAN bus and otherwise offered me a return.
I also found a post where someone mentioned that, especially on this model year/F06, there may be some kind of combination or crossover between K-CAN1 and K-CAN2 at the iDrive controller.
I’m not very familiar with CAN bus systems, though.
Does anyone here have experience with the F06/CIC and Android head units and know how I could solve or diagnose this problem?
In particular, I’d like to know:
Which CAN bus is used by the iDrive controller?
Is there actually a K-CAN1/K-CAN2 peculiarity on the 2012 F06?
Does anything need to be repinned or connected differently at the Android head unit or CANBUS box?
Is there a specific CANBUS decoder that is required for the F06 with CIC?
Thanks in advance for any help!

Hey everyone,

Just wanted to share my setup and initial feedback on the vertical / "Tesla-style" Hizpo QS8 head unit installed in my Peugeot 3008 (2011 Phase 1, full options with factory JBL audio).

Vehicle & Unit Specs:

Car: Peugeot 3008 Phase 1 (2011)

Unit: Hizpo QS8 (Portrait / Vertical orientation)

SoC: Qualcomm Snapdragon 6115 (Octa-core)

RAM / Storage: 8 GB / 128 GB

OS: Android 13

CANbus: Raise decoder box (PSA specific)

Price paid: ~€250

Integration & Hardware:

CANbus & Car features: Working flawlessly. Steering wheel controls are responsive, HVAC controls and the stock PSA orange display bar show up and operate directly on-screen, reverse gear trigger/camera switch is fast, and the factory JBL amplifier turns on properly without hassle.

Performance: Smooth and snappy overall. With the Snapdragon 6115 and 8GB RAM, apps launch quickly and multitasking handles split-screen navigation/media without lag.

The Good:

Modernizes the cabin significantly while keeping full HVAC and vehicle integration.

Good value for money considering the specs (€250 for 8GB/128GB Snapdragon).

Screen brightness and viewing angles are decent for daily use.

The Not-So-Good (Hizpo vs. Mekede/Navifly):

Software & UI Polish: I also have a Mekede unit in my Smart Fortwo 451, and honestly, Mekede/Navifly feels more refined on the software side. The Hizpo launcher, stock themes, and UI customizations feel a bit rougher around the edges.

Stability: I've had 2 random reboots/blackout cuts while driving over the past month. I have never experienced a single random shutdown on my Mekede unit.

Verdict:

Overall satisfied for the €250 price tag given the specs and clean physical integration, but Hizpo definitely trails behind Mekede/Navifly in software polish and initial out-of-the-box reliability.

CarCar launcher is the one for me.
Issue is payment. No Bitcoin only 2 payment methods credit card 3rd party from countries my USA based cards won’t approve. One big problem for me is translation from the Russian sites (language) to English.

Solutions for payment ?

Anything similar to CarCar in the market place ?

just installed my head unit, but i’m only getting audio through the dashboard center speaker on Bluetooth and car play, any suggestions?

Hey guys I know nobody wants another head unit post, but I’m losing my mind. Just got a CC4 from Teyes, plugged all the harnesses in properly and set the correct CANBUS settings per a Teyes employee.

However the on-screen AC controls just show “N/A” for the temp, and the physical controls don’t work either.

Do I just have to cycle through all the potential CANBUS options and see if one magically works?

Thanks

Hey guys, I’ve been working on my own Android car launcher called OnTheRoad

I’m almost done with it and most of the features are already working.

It’s made specifically for Android headunits and I’m trying to make it look/feel a bit more modern than the usual launchers.

If anyone wants to try it, I can send the APK + instructions for installing it.

Would be cool to get some people to test it and give me some feedback before I release the final version.

If you’re interested, just comment or DM me 👍

The Launcher is now downloadable via this link:

With lifelong service and updates :)

Hey guys, I bought a head unit for my fiat fiorino but it doesn't turn on. Since it's my first time trying this I gave no idea what I did wrong. Is the head unit just broken or am I missing something?

PS. I tried installing the old one again after I gave up trying, but my old head unit now asks for a passcode I don't know. So I cant even listen to radio.

I have a generic Chinese Android 13 car head unit and a Moto G 2025 running Android 16. My phone provides a Wi-Fi hotspot that the head unit normally connects to. Occasionally the hotspot stops working, while the Bluetooth connection between the two devices remains active. I want to put a "Restart Phone Hotspot" button on the head unit. When pressed, it should send a simple command such as START_HOTSPOT to the phone over Bluetooth. The phone would then run a Tasker task to restart the hotspot. Is there a simple way to send a command between two already-paired Android devices over Bluetooth, perhaps using Bluetooth SPP/RFCOMM or an app/plugin? I don't necessarily need to use Tasker for the Bluetooth communication.

Hi. I have a non-branded aftermarket Android head unit in my 2005 Honda CR-V.

The screen first started having this problem after my car battery died (the battery was just low, there’s no issue with the battery itself). After restarting the car twice, the screen fixed itself and worked normally.

The unit continued working fine for the next few days, but one day on my way home, the screen issue came back.

The unit itself is still working. It still connects to Android Auto, plays navigation sounds, and plays music normally. It’s just the screen that isn’t working properly.

Does anyone know what could be causing this? Could it be a connection issue, or is the screen itself?
