The only time I've ever had position errors greater than, say, 15m or so, is when I've first turned the unit on. Whilst it's looking for satellites, the track-log records the current position as where I last turned the unit off for a few seconds until it has a signal lock. However, there might be a couple of causes to large errors; * Some cars are known not to permit very good GPS reception. This would tend to be shown in the +/- position though. * I have heard from others that an earlier version of the software or firmware was known to cause accumulated errors. When I first bought my unit, it was installed with a version previous to these which was fine. I have since upgraded to a later version which is fine. But in general I've never really had any issue with it, other than the rubber part 'ungluing' itself, which is apparently a common fault. _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
