Had a rather depressing confirmation of the GPS troubles this weekend. Went on a quick trip to London, and turned on the map application as soon as I got on the Heathrow Express heading into town. During the trip, the map application showed the GPS finding 3-5 satellites on the average, but it never managed to determine the position. Nor during my walk to the hotel, nor during a walk across St James's park, and not even overnight next to a corner window on 5th floor - it just ran out of charge trying. In the end I got back to Amsterdam without the GPS having acquired a lock during the whole trip. Not very useful. A real bummer, because the 2 main applications I got my 810 for was mapping and in-car ODBII, and CarMan doesn't run on the 810... :( Sounds like I should sell my 810 and stick to the 770... :( Julf
