The other day i drove 1½ hour on the E45 and i noticed that the GPS-signal was missing partially and coming on randomly. As the wather was good i couldn't figure out what caused this behaviour. I tried different speeds and noted that as long as i drove above 100km/h the GPS would shutoff and lose its lock. Coming down below 80km/h the GPS went back on for a while and then lose the signal again. The clip below shows the GPS-signal coming back on at the parkinglot in Krusaa, DK. But please note the speed on the freeway is zero'd until 50sec later.. It happened the same day i did a format of the sdcard. I drove home a couple of hours later, where the GPS was OK all the way home on freeway. No problems.. Have anyone noticed this behaviour before?
