Hi Cadillac Techperts:

CAR: 2006 CTS 2.8


PROBLEM: I bought a NAV radio off of Ebay and replaced my radio/CD player on my 2006 CTS.

The original radio DID NOT have NAVIGATION System.
The local dealer unlocked the Theft Code for $95.

I also bought the correct GPS antenna for this unit.

I hooked it all up and to my disappointment, the red NAV Arrow on the screen rotates when I turn the car, but the entire map DOES NOT scroll or move ahead when I am driving down the road.

The GPS seems to pick up the satilites and positioning when I display GPS position, but the screen does not move.

Parts & Details:

>> The GM NAV Radio is stock and is date stamped December 2004
Part #25750936, Hollander # 638-01605

>> The Antenna is: ACDelco 25726417 Antenna Assembly

>> The NAV Disc in it says "Cadillac DVD Rom - Canada / US - Version 6.0Q4 02, 2002 Navigation Technologies, 25766899

Everything else works on the unit: Radio, CD, it even plays DVD Movies!

This Drives Me NUTZ !!!!
