I'm considering adding a Nav to my 03 deville but don't see from the Nav screens that the factory XM is available. My car is an 03 Deville, non Bose, with XM.

CadillacSTS2003, I'm too new to PM - could you email me at V8q@bellsouth.net or pm me? Don't mind getting a Nav from you since from reading your 'installing Nav' thread you've got the expertise.

For anyone else, there's an 03 Seville NAV on ebay (LKQ) ending today.
