Hello,
I recently purchased a Dasaita Android 13 head unit for my 2014 Toyota Tundra through Amazon.
The unit worked perfectly for approximately one week.
It now has the following issue:
Wireless Android Auto disconnects every 3 minutes almost exactly.
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.
Phone:
Google Pixel 8 Pro
Android Auto version: 17.2.662614
Head Unit Information:
Android 13
Platform: QCM6125
Build: QCM6125 13 S10A_123 (20250903)
MCU: MTCHC_HA4Z_V4.16_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.
Thank you.
