PAC RadioPRO5 RP5-GM11 GM Radio Replacement Interface – OnStar & Steering Wheel Control Retention

Upgrade with PAC RadioPRO5 RP5-GM11

Refresh your GM era dashboard with a plug and play radio replacement interface that preserves essential OEM features. The PAC RadioPRO5 RP5-GM11 is designed to keep OnStar connectivity and your vehicle’s steering wheel controls intact while enabling use with radios that include non amplified audio systems. Built to work across a broad range of GM, Buick, Cadillac, Chevrolet, GMC and other partnering brands from the early 2000s to the 2010s, it helps you modernize your cabin without sacrificing familiar, trusted functions.

Two core benefits stand out for daily use. First, OEM feature retention lets you keep familiar safety and convenience cues as you install a new head unit, with a focus on OnStar compatibility. Second, the pre loaded steering wheel control software means you can keep factory style control without re programming. These elements are designed to work in tandem with a modern head unit while respecting the original vehicle design.

What you gain at a glance

You’ll also receive an antenna adapter for smoother installation and, when needed, a Toslink option for a clean digital output to aftermarket amplifiers or DSPs. The unit ships with a plug and play harness to speed the install and reduce wiring complexity.
