Where this fits in the build

The source unit has to fit more than the dash opening. Steering-wheel controls, factory cameras, amplified audio, chimes, USB, vehicle settings and data integration can change the correct installation path.

Plan aroundConfirm dash fitment and the factory features that must remain.

Description

PAC GM6A-RST RadioPRO Advanced

GM6A-RST is for supported GM radio replacements where the vehicle’s OnStar system, Bose factory amplifier, steering-wheel controls and navigation outputs all need to remain part of the installation.

This is a different integration path from the simpler GM1A and GM3A interfaces. The Bose amplifier and OnStar retention are part of the architecture, not optional add-ons that can be assumed from year alone.

Where It Fits

Use GM6A-RST only where current PAC application data specifies this model. Confirm exact vehicle, OEM radio, Bose system, OnStar and connector/data-bus architecture before quoting.
