Real simplicity

This PAC module allowed to install an aftermarket stereo with no issues that would normally arise trying to replace a GM factory stereo. Everything just plugged in and after a few simple connections, it only took about 15 minutes and everything works fine without the loss of the information center and chimes. If you are considering a factory stereo swap I think this is the only way to go. This is probably the easiest install I ever done.

Worked EXACTLY as Expected

Very easy to install. Piece of Cake. Took 10 min with a solder gun and heat shrink tubing. Plug and Play.

Makes installation easy

Makes installation of after market radio simple. I used this in conjunction with the Pac ControlPro steering wheel control interface and Metra 70-2103T radio relocation harness. No problems with the C2R-GM11B
