Introduction and Features

Important Notes

1. The radio select dip switches on the side of the interface must be set to the proper radio selection before plugging the interface

into the vehicle.

2. The interface comes pre programed for all vehicles factory default SWC functions. These can be reprogrammed if you wish

to change functionality, please refer to Optional SWC Programing section on page 3.

3. RSC buttons that are identical to the SWC will mimic the SWC one for one.

4. If the vehicle chimes when the radio is removed, the CMX is not necessary. In order to get the best possible sound out of the

CMX, please mount it in a place free and clear of any obstructions, preferably as close as possible to the bottom of the dash

pointing down toward the oor of the vehicle.

5. The external speaker, part number (RP-SPX, Sold Separately) must be used when installing a 4 channel amplier to retain

the OnStar prompts. It can be purchased through any PAC authorized dealers if required for your installation.

Technical Bulletin RadioPRO5 Accessory Power Output Drop-out At High Volumes Overview Symptom: The 12v+ accessory output drops out at high volume causing the aftermarket radio to shut down. Cause: Aftermarket radios with high powered speaker outputs, played at high volumes, cause the interface’s components to overheat, thus resulting in the 12v accessory output failure. Solution: Wire 3 of the 4 factory speakers directly to the outputs of the aftermarket radio, bypassing the interface.
