RE: ipod hookup?
you are in the same boat as me.. I have an 03 as well. If you have the pewter dash then it is possible your radio is the older style and you won't be able to hook it directly in... There are some posts where youcan enable the XM part of the radio and use that as the source.. again... it will depend on your radio... do a search for having your radio done using the Tech2... or search for the Caddipod.. there are several out there about it...
