Just purchased an 08 Platinum and I'm pretty much lovin life. Been lusting after one since they came out. Anyway, what would be involved in replacing the aux input with the usb/aux input from the 2010 and up. Also could I add the factory xm to my system or would that mean a total replacement of existing nav/stereo unit? Thanks for any help.
