Radio Setup



Radio Setup

Radio setup is completed using the Service Programming System (SPS). Refer to Service Programming System (SPS). Programming and Relearning

If exchanging the same radio, from one vehicle to another, the VIN from the vehicle receiving the radio needs to be programmed with the scan tool.

Use the program VIN procedure available in Special Functions menu of the scan tool. After programming the VIN cycle the ignition key with the retained accessory power (RAP) disabled.

Important: The radio setup files will configure the radio amplifier (if equipped), internal equalization settings, and program the vehicle identification number (VIN). Without the following setup procedure, the sound quality and volume of the radio may be degraded.
