'06 DTS navigation system

[AAA Accurate1]

I recently upgraded from a '02 Deville DTS to a '06 DTS. The only option in the '06 that I didn't get was the navigation system/dvd/6 disc changer.I recently wa able to pick up the new system at a fraction of the original cost on E-Bay. When I brought the car to my local Cadillac dealer to have the system installed,they told me that my car isn't wired for this new system,and they don't show having any wiring harness available to convert over to the new system.I have been searching all over the internet for options, but no success yet. Has anyone encountered this problem, and I feel sure that in 2007 it's got to be possible for me to do this. HELP !!!
