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.
Finish itUse the correct vehicle interface instead of sacrificing OEM functions unnecessarily.

Description

PAC GM3A-RSTX RadioPRO Advanced

GM3A-RSTX is for supported General Motors radio-replacement applications using the GM LAN 29-bit data bus and the specific 14-pin/16-pin harness architecture PAC designed this interface around.

This is not a generic GM interface. The network generation and connector set are part of the fitment decision, along with OnStar, factory amplification and the original radio configuration.

Where It Fits

Use GM3A-RSTX only when current PAC application data identifies this exact interface for the vehicle. Do not substitute GM1A-RS/RST or GM6A-RST simply because the vehicle is GM or has OnStar.
