I have a quick question... I have a 2006 CTS w/out a nav. system and im looking to purchase one... i learned through these forums (thanks) that i should buy the DVD version of the nav. system. I was wondering if there is a sure fire way to have all my functions with the DIC to work with the new installed system? My biggest question s whether or not the OEM navigation system for the CTS plays mp3 cds becasue i use alot of those... this will deterine whether i will go the route of the factory nav unit or an aftermarket unit...
Thanks
Thanks
