I just finished installing a OEM GM Nav system, Part No. 25846421 with an OEM GPS antenna Part No. 15201798. Aboslutely everything works EXCEPT there is a red line through GPS. When I drive the vehicle the surrounding streets move but the GPS can not find my location. The reverse camera works fine as well as the lock pick. Does anyone have any idea what I need to do to activate the GPS signal ?
