Hello,
I am trying to determine the correct firmware update package for my specific unit to get Z-Link functional. It currently gives a internet connection error despite being connected.
My current information:
- Vehicle: 2015 Toyota Camry
- Head unit: Dasaita PX6
- Android version: Android 10
- CPU/platform: RK3399
- MCU version: MTCE_HA_V3.7_1
- Build number: rk3399-userdebug 10 (I can provide the full build string if needed)
The unit currently has the ZLink app installed, but I would like to update it and improve Android Auto/CarPlay compatibility if possible.
Could someone please help me identify:
- The correct firmware package for this exact PX6 Toyota unit?
- Whether there is a newer Android 10 firmware available for MTCE_HA?
- Whether ZLink should be updated separately or only through a firmware update?
I do not want to install the wrong firmware and risk losing features like the steering wheel controls, backup camera, or CAN bus functionality.
Thank you for any help!

Hello.
To further confirm, please go Settings > About Machine,
then provide the complete Build Number information.

Ultimately my goal is to get Android Auto functionality. From my research it seems Z-Link is not activated or not up to date, because it asks for internet connectivity despite being connected. The Z-link app version is 4.0.14, please let me know if this needs to be updated to function properly.
