I am running Greenster SF2 and Autotrac Universal on a Spra Coupe. I am getting an intermittent error message saying GPS updates 1 Hz, Tracking Inaccurate. This is on an original display and the tracking line on the screen seems to skip say 30-60cm off the line for a few moments than recorrects. Any help on what could be the cause would be much appreciated.
