Step 1: Press the FM/AM button and check the radio for sound .
A: If you can hear the FM sound, please go to the PEMP system homepage, then click Settings-Car Settings-Original Car’s Screen Resolution in turn, then choose the resolution suitable for your OEM screen, then restart the screen.
B: If you can't hear the FM sound, it means the screen is in unpowered state, you need to check all the ISO harnesses and plugs and unplug them all and plug them in again. Then check for loose power and LVDS cables behind the screen.
Note: In order to prevent the plug from loosening, the plug is designed to be relatively tight, you can use a little force when inserting, please ensure that the plug is completely inserted to the end.
Step 2: Some cars have fiber optic cable on OEM ISO harness, if your OEM ISO harness has fiber optic cable, please transfer it to PEMP ISO harness. Otherwise, it will cause no sound/no time display/no display of OEM system and so on.
