Compatibility & What You Need

  • Main part: PAC GM6A-RST. The part number and factory-equipment requirements must match the application exactly.
  • No separate PAC interface is identified as universally required; application-specific dash, antenna, USB, camera, or installation parts may still be needed.
  • Aftermarket radio: Sold separately. Confirm it has every input and output required for the factory features you want to retain.
  • Professional installation is strongly recommended for data-bus radio replacement and factory-amplifier integration.

Important Application Notes

  • Rear-seat entertainment, Wi-Fi, Teen Driver, Valet Mode, camera-overlay symbols, front camera, ambient-lighting controls, and several performance or convenience settings are not retained.
  • Some listed vehicle settings can no longer be changed after the factory radio is removed; review the current PAC instructions for the exact model before installation.
