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.

Description

PAC OS-5 GM 29-Bit LAN Radio Replacement Interface

OS-5 is for supported older GM 29-bit LAN vehicles where replacing the factory radio still needs the vehicle’s factory options to work. PAC supports the interface in listed vehicles with or without Bose, including applications that retain OnStar, steering-wheel controls, chimes and factory amplification.

This is a network-specific interface. It is not interchangeable with later GM RadioPRO Advanced or AmpPRO products simply because the vehicle is Chevrolet, GMC, Buick or Cadillac.

Where It Fits

Use OS-5 only where current PAC application data specifies the 29-bit LAN OS-5 path. PAC’s manufacturer application documentation includes older Chevrolet/GMC truck and SUV platforms among the supported vehicles; exact model/year and factory equipment must still be resolved before quoting.
