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, click “Settings” - “Factory Settings” - "070305" - "Vehicle display" and "CAN Protocol" , and select the vehicle protocol and resolution Select the option that corresponds to the OEM system.
B-1: If the OEM screen still doesn't display properly or you can't hear the FM sound, you need to check if there is a fiber optic cable on the plug of the OEM ISO harness, and if there is, you need to transfer it to the PEMP ISO harness.
B-2: Because the plug is designed to be tight in order to prevent the plug from loosening, it is easy for the ISO plug to not be inserted to the end and have poor contact.
Therefore, we need to unplug the ISO plug, and then re-insert it, you can use a little force when inserting, please make sure that the plug is completely inserted to the end.
B-3：Then check the LVDS cable behind the screen and the white power plug.
As some cars have less space to install the screen, it is easy for the cable to be squeezed, which can lead to loose plugs and poor contact.
So we need to unplug and re-plug the cable and make sure it is fully inserted and that it is not pinched when installing the screen.
