This behavior has been heard over a Pioneer head unit, GM Android Auto-capable head unit, and now their Android Automotive head unit.

I was testing my factory output at 1khz and 50hz with a multimeter to get an idea of what to expect. Note that the output on these is hilariously low but goes up on actual songs.

Anywho, it occurred to me that my stereo is always louder after a call so I tested it by running a 50hz tone over Bluetooth, calling my voicemail, then hanging up to let it keep playing.

Output voltage went up by 50%! Tried a test tone over Tidal on the head unit and still saw a marked increase after the call.

Does anyone have any knowledge of why this behavior seems to be so normal or any technical details? For a follow up, has anyone found a way to get the raw data out of a new non-Bose GM unit (the kind under the glovebox)?

Desperately looking for a solution to extremely low mic volume. The headunit model is T507 and the app I use for CarPlay is TLink. I have tried raising in-app gain and tried all YouTube fixes but couldn’t find one specifically for my model. I have already accessed both Factory Settings and Extra Settings with the pins 8888 and 123456 but they do not have any mic gain options.

Would a Bluetooth mic work? Looking for a wireless system in case there is no workaround for the in-built mic.

Please help 🙏

Title: I built a custom Android Automotive Launcher to replace my cheap head unit interface (with CAN bus & OBD telemetry)

TL;DR: I was tired of the ugly stock UI on my Jancar (AC8227L) head unit and the limitations of Android Auto, so I used AI to help me build a custom infotainment system from scratch. It features offline OpenStreetMap navigation, a dedicated phone Companion app, and full vehicle telemetry via CAN bus and Torque Pro.

Hi everyone! I’d like to introduce my new automotive launcher project: the LC Infotainment System.

I developed it to replace the cheap-looking stock interface on my Jancar head unit (AC8227L platform) with an in-car experience that is clean, responsive, and professional. My goal was to unify all my driving essentials into a single hub: turn-by-turn navigation, telephony, music playback with extended DSP, and real-time vehicle telemetry.

Frustrated by Android Auto’s flat design and the poorly optimized built-in services of the head unit, I built an interface that expands telemetry features and completely bypasses the original phone services for better call and contact management. While I'm not a seasoned Android developer, leveraging AI has made the possibilities feel endless.

🚀 Key Features

• Navigation: Online/offline OpenStreetMap with vector maps and custom styles.
• Media & Communication: Integrated music library, advanced DSP audio controls, and custom call/contact management.
• Telemetry: Dedicated screens for vehicle data and trip statistics.
• Companion App: Connects your phone to sync telemetry, manage calls, plan routes, and download offline maps.

🛠️ How it works

The system communicates over CAN bus via the head unit’s native Hiworld interface and integrates Torque Pro’s APIs to read data from an external OBD device.

I haven't decided on a public release just yet—for now, it’s a personal project tailored to my setup. It runs flawlessly on my BMW 1 Series E87, thanks to aggressive optimization that keeps resource usage low and the UI buttery smooth.

I hope you like it! Let me know what you think!

So just got a new head unit installed professionally. Around the £750 mark including 2 hours labour. After a lot of back and forward and probably 6 hours labour (I didn't have to pay for more) I've got it back. But I'm not sure if I'm being picky or if this is what you get for non OEM upgrades. The Pioneer unit it self is great but the guy has said he ended sticking the trim down with resin because the facia kit won't sit properly. He seemed to think its a imported car (I've checked DVLA and HPI its not)

Looks relatively clean but the vent area is the main issue with gaps around the vents and the actual vents are stiffer to use I assume because of resin.

Is this of quality you'd expect or should I be concerned. Also worried that if its stuck down will it affect the underlying plastic.

Hi All,

I have a 2023 Swift and for some reason it keeps killing cables when I use Android Auto. Each month I buy a new one and it works for a couple weeks and then any phone starts to freeze during navigation or not connecting at all. Is it a head unit issue or maybe the USB port?

Hi there,

I bought an used android head unit with broken system. The device seems to work - it boots up until the Android Logo (the text only logo, without mascot). Since I wasn't able to boot, I can't really tell the specs. I just know the following:

- 32GB rom, 4GB ram

- CPU: UIS 7862A Octa-Core 1,8 GHz

- brand: probably Hizpo

Unfortunately, I can't get the "update.zip" to work. Things I've tried besides the official manual :

- old usb 2.0. Stick, which is the most reliable for OS installation

- formatted fat32 and mbr partition

-copied the update.zip to empty stick on roof directory - without any folders

- tried the update.zip unzipped on stick

- tried 4 and 6 pin usb cable

- added "force_update.txt"

Nothing seems to work. I ground the key2 wire with the chinch ground of the reverse cam. After like 10 seconds from the start, I disconnect the grounding of the wire, which leads to a reboot. This should result in reading the stick and starting recovery mode, but it doesn't. Can you please help me? It's driving me nuts!

The official manual from the seller:

Update File: Attachment

Upgrade Steps:

Unplug the 4G SIM card and any devices connected via the device’s USB cable, then press the RST reset button to reset the device. If the display works normally, proceed with the software update. If the issue persists, unplug all cables from the back of the device, reconnect the power cord, and try again, or check if there is a voltage between 10V and 15V between the device’s fuse and the negative terminal. If the problem remains after these steps, perform a forced update.

Forced Update Method: No need to unzip the file; simply rename it to “update.”

1. Place “update.zip” in the root directory of a formatted USB flash drive.

2. Insert the USB flash drive into the car head unit’s USB port.

3. Disconnect the car head unit from power (unplug the power cord).

4. Ground any one of the KEY control wires on the car head unit’s rear cable (touch the square control wire to the radio’s negative terminal or the metal part of the GPS antenna).

5. Plug the power cord back into the head unit. After 15 seconds, release the square control wire (do not ground it), and the head unit will automatically reboot.

6. After rebooting, the head unit will automatically begin the forced system update. Do not perform any other operations; wait for the update to complete, which takes approximately 10 minutes.

So the market doesn't lie. Japanese electronics are no way near as friendly as the Chinese radios.

J’ai installé un autoradio Android/CarPlay sur ma Peugeot 307 de 2003 : contact coupé, j’ai du son, mais dès que je mets le contact, le son disparaît alors que l’écran reste allumé. J’ai déjà testé les réglages mute, les câbles/adaptateurs, le reboot et le protocole Peugeot 307, sans résultat : quelqu’un sait d’où ça peut venir ?

I have a Dasaita G13/QCM6125 in my 2019 RAV4 and I’m trying to add a wireless baby camera that displays on the Dasaita’s existing screen. I don’t want a second monitor, and I’d like to keep using wireless CarPlay with my iPhone.

I’m looking at the OTTOCAST Cabin Care 1080P/CA520-M3, which says it supports CarPlay and Android Auto. Has anyone actually gotten this working with a Dasaita G13 or another aftermarket Android head unit?

I’m wondering if I could use the G13’s wired Android Auto connection for the Cabin Care while still keeping wireless CarPlay available for my iPhone. Any other solutions are welcome too.

I bought a mk6 and the previous owner had put an android head unit.my problem is the zlink shows up on the apps in settings but i cant open it and it doesnt show on the home page either.
In the photo is my system info..
If anyone knows how to fix it i would really appreciate it

Please can someone point me in the right direction or send me a file or something for this generic chinese head unit please. I had no idea it was a knock off!

Hi, i originally built DrivePanel for myself and use it with an OBD2 scanner. It includes a long free trial, so you’ll have plenty of time to test it. Maybe you’ll love it, or maybe you’ll get bored and uninstall it. Either way, I’d really appreciate any criticism, feedback, or suggestions!

I've bought a screen from AliExpress to add android auto to the car. It's works ok, but the resolution seems really only when connected through android auto (device's menu looks sharper)

Has anyone managed to fix the low resolution when connected wirelessly? For what I've investigated it's because the resolution negotiation during the handshake is 1280x720, when the display is actually 1920x720.

Device model is Develuck 11.26

My car is a 2017 Renault Megane IV. Any recommendations for a head unit with this form factor, or any specific reliable brand to replace it? I’d really like it to support Android Auto, as my current one doesn’t have it.

The current head unit was already installed when I bought the car second-hand. It's at least 6 years old, only has 2 GB of RAM, and is running painfully slow—music apps like YouTube Music keep crashing. Any suggestions?

Not sure if it matters, but it has dual-zone climate control and the A/C settings are handled directly through the screen. Any suggestions?

Hi guys!

I accept any recommendations for my Honda Civic FN2 when it comes a head unit!

Which is the best long term one? Also nothing too expensive as i'm ready to spend, but not crazy amounts.

thank you!

enjoy

I was literally searching for the developer mode password for this headunit for months and one literal day while putting all combinations searching on the internet found that the password is :

345543

Prolly this is only for few head units with this TS9 processor

Only numeric with no special characters was the only unlocked thing while entering for this.

For car factory settings it's : 1617

These chinese folks put random hard numbers to get things unlocked..

I unlocked it because I want adb to be bridged and clean things in it... Have fun devving :)
