Just bought a pre-owned 2005 CTS, loaded with the Navigation system. Unfortunately that manual wasn't in with the rest of the manuals. Could someone either email or post a pdf of the manual (or a link to it) to ricknerinfenton@sbcglobal.net I sure would appreciate it, I'm looking forward to diving into the navigation system! I have tried www.cadillacfaq.com, the link to the navigation manual doesn't seem to work.
