Hey guys installed my PAC Nu-GM29 Navigation Unlock unit and now im having problems with my navigation. When the unit is disabled my navigation is about 300 yards ahead of me!!! I called and complained and they even sent me a new unit which is doing the same thing.

Has anyone experienced this issue before? Any way to recalibrate the stock navigation unit? What are my options?

Did you ever figure out this issue?

Nope very annoying. Guys at Pac tell me that they have never had any issues with this. I unplug the unit from the stereo and the navigation goes back to normal but when i plug it back it and a day or so later it gets all messed up again.

Has anyone else had similar issues?

I'm having this installed this week. Hope I don't experience the same thing.
