View Full Version : 04 Navigation screen moves slow

04-04-08, 12:41 PM
I installed an OEM nav system in my 04 Escalade but while I am driving the screen moves too slow, so I am never where the map says I am. How can this be fixed, I took it to the dealer and they said they couldn't fix it. I have 22" aftermaket wheels, could that be the problem? Can the speedometer be re-calibrated? The dealer put a Tech II on it but said there was no calibration for my truck. Please Help.:confused:

Make sure the antenna that you installed under the dash pad has a clear satellite reception. Make sure your VSS wire is correctly attached.

I checked that and that wasn't it, does anybody else know what might be happening?
