Compatibility and installation

Fit depends on the exact vehicle, model year and factory audio equipment. Verify your vehicle in PAC’s AP4-GM61 application guide before ordering. Requires the compatible Bose/MOST50 system; it is not a universal GM adapter.

Package includes the interface module, harness, bass-control knob and knob harness. Aftermarket amplifiers and the optional APH-GM02 speaker-connection harness are sold separately.
