I finally got around to updating my firmware and like everyone else the GPS was no longer recognized. All I had to do was remove the camera from the GPS module and put it back on, while the camera was in operation. Then power down and back on again. Lastly you have to allow it to calibrate again, which means driving at least 20km/h for several kilometres. Not so easy to do in city driving with lots of intersections, but I managed it.
