OEM Headunit replacement
I have a 2007 C6 with the upgraded Bose system and XM radio. I want the head unit with the AUX port. Are there different OEM head units that I have to look for or will any work? I don't want to lose XM Radio. I was considering purchasing this one from Ebay, but I want to make sure they are all plug and play, relatively speaking. Thank you..
