I recently purchased a Dasaita Android 13 head unit for my 2007 Toyota FJ Cruiser through Amazon.
The unit worked perfectly for approximately one month
It now has the following issue:
Wireless Android Auto disconnects every 3-4 minutes almost exactly. It reconnects and repeats.
The head unit does not reboot. It exits Android Auto and returns to the Zlink application.
Zlink then displays connection errors.
When pressing the CarPlay/Android Auto button, I receive the message: "Android Auto is in use, please disconnect Android Auto and reconnect again!" even though only one phone is connected.
I have already cleared Zlink data, repaired Bluetooth, and restarted both the phone and the head unit.
Head Unit Information:
Android 13
Platform: QCM6125
Build: QCM6125 13 S10A_123 (20250903) NA-V2.1
MCU: MTCHS_HA4Z_V4.16f_1
Based on my troubleshooting, this appears to be a Zlink software or firmware issue, not a wiring or installation problem.
Could you please provide:
The latest firmware for my exact model.
The latest Zlink APK/update.
Any known fix for this issue.
I can also provide photos and a video showing the problem if needed.
