GM vehicle owners looking to upgrade their factory radio, this PAC interface makes the swap actually work with your existing systems.

The RP5-GM11 retains OnStar functionality when you replace the factory head unit - something most aftermarket radios can't do.
It also keeps your steering wheel controls working, so you don't lose volume, track changes, or phone controls.

Compatible with a huge range of GM vehicles from 2000-2013, including Chevy Silverado, Tahoe, Suburban, Corvette, Colorado; GMC Sierra, Yukon; Cadillac Escalade; Buick LaCrosse; and many more.
Also retains factory Bluetooth on 2009+ models and rear seat audio controls.
Works with Bose audio systems and supports dual zone audio functions.

The installation is straightforward if you're comfortable with car audio work, but the retention of all these features makes it worth the effort.

If you've been wanting to upgrade to a modern touchscreen radio with CarPlay or Android Auto but didn't want to lose OnStar or steering controls, this interface solves all those compatibility issues.

The build quality is solid, and the instructions are clear for professional installers or confident DIYers.

Seriously, if you're upgrading your GM factory radio, this interface is the key to making everything work together properly.
