Hey guys. I'm new to the forum and I just got my 06 CTS. I did get the BOSE system but could not get the NAV unit (I have to wait 2 months if I want a car with the NAV in it!!!). I was browsing and found this part (10359362) which is a 05 NAV system. So my question is, if I get this will it work on the 06? Will it be kind of a plug and play or do I have to do all kinds of wiring stuff to make it work? Any help will be greatly appreciated!!
