I have decided after a long search for the Garmin 255WT - and sent it after a short test back: - Find that the GPS satellite took a long time, up to 5 minutes. just in the city or to places where you know your way non, must go faster. - In the city was the actual position misrecognized car was displayed on a parallel street. the navi then tried me, steer back onto the road, where I already was. - At a slightly more complicated motorway exit, the navi was completely messed up - after originally correctly displayed route came to take the exit a number directly successive announcements contradictory: "right, on lane right, right, on lane Right, Right, Right, Left "that changed map back and forth chaotically. - Once the navi turned off for no apparent reason.
Conclusion: no use. I've now ordered a 3rd f10 falcon.
