is still noise after exclusion, please check whether the ground wire is connected with the CD or DVD housing, still can not be
excluded, please return to the factory for maintenance.
3. No working indicator light/no sound: please confirm whether the host cable is correctly connected, check whether the original
car has its own power amplifier or whether there is a modified power amplifier.
4. Both the main engine of the original car and the local machine are energized: check whether the power supply of the original
owner is properly connected and whether the ground black wire is connected to the main engine of the original car.
