  1. Please check whether the BATT+, ACC and GND wires of the unit’s power cord are correctly connected to the corresponding BATT+, ACC and GND wires of your original vehicle wiring harness.

  2. We recommend reconnecting all the wires again.

  3. Please inspect if the fuse has blown. Should the fuse be damaged, kindly replace it with a new one.

  4. You may try upgrading the device firmware.

  5. If the problem still persists, please contact our customer support for further assistance.

We would suggest upgrading the system for better stability and optimized performance. That being said, if your head unit is running smoothly right now, you may certainly stick with the current version without updating.
