Review on PAC C2R-GM11B Radio Replacement Interface: Enhanced Compatibility for 2004-up GM LAN Vehicles without OnStar by Warren Hess

Perfect fit for my car, keeps the warning tones in my 2007 Chevrolet Malibu when I install an aftermarket radio. Setup was a breeze thanks to color-coded cables, included instructions, and a few YouTube videos. Disassembling the front panel was perhaps the hardest part. The wiring itself took only a few minutes and several wire crimps, the wires were even pre-stripped. I would recommend this to anyone with a 2004-2007 Malibu looking to install an aftermarket deck.
