What he said.

Radios are integrated with the BCM. There have been reports of problems with the security system without a module like the GMOS-01. It also makes it easier to install. There's no hacking of the factory harness, so if you want to put the factory radio back it, it's a matter of pulling out your modules and plugging the radio back in.

You'll also need a mounting bracket. This is the one you'll need if that new head unit is the double DIN radio I think it is.

BTW... you'll lose the date function of your DIC when you remove the factory radio.
