RADIO / OEM FUNCTION FIT

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.
Match itMatch the radio to phone, camera, audio and interface requirements.

Description

PAC GM1A-R RadioPRO Advanced

GM1A-R is for supported GM radio-replacement jobs where the factory chimes and amplifier need to stay in the system, but steering-wheel-control retention is handled through an optional compatible interface rather than built into this model.

That makes GM1A-R a different architecture from GM1A-RS and GM1A-RST. Do not choose between them by price alone; the vehicle’s retained-feature requirements decide the correct part.

Where It Fits

Use GM1A-R only where current PAC application data specifies this exact interface. Confirm the factory radio, Bose/non-Bose system, OnStar requirement, steering-wheel-control plan and data-bus generation before quoting.
