Do you lose any functionality if you remove the factory stereo in a 6th gen? I just got my ride back from the bodyshop, and they reset the ECU, and I don't have the code for my stereo. If I'm going to take my head unit out to get the serial numbers, I'm just putting an aftermarket in while I'm in there. I just wanted to make sure this isn't going to disable my keyless entry or anything, as I know sometimes crazy stuff like that happens.

thanks
