Andrej-
I have just upgraded my SeeYou to 3.4 and Mobile SeeYou to 2.6. When I try to use Mobile SeeYou I get "NO GPS DATA" on the iPAQ (model 3955). I know the Volkslogger is working because the flight is recorded and I was able to download the flight to SeeYou on my PC. A second problem is that the map is only partially displayed and when the track goes off the displayed map it takes 30 to 60 seconds before the the diaplayed map is updated to cover the area I am flying. I did try reinstalling Mobile SeeYou but problems are still there. Neither of these problems occurred with my prior versions. SeeYou 2.8, Mobile SeeYou 2.11
