GPS Problem

[miggy]

I've just got a Garmin emap GPS.

When on the road the 'pointer' will often veer quite wildly off the road that I know I'm travelling on though roughly following my direction of travel.

At home however if I upload the track to my laptop it gives an exact track of the actual route/track that I've just travelled with no mistakes at all, spot on.

I'm puzzled?

I've not used an eMap, but if it is like the other Garmin units then the 'pointer' will point directly to your destination waypoint. Probably the road doesn't go in a straight line to the waypoint, hence the disparity.

Sorry I didn't explain it very well. I'm pretty familiar with GPS (no expert).

I know using waypoints that the pointer points 'as the crow flies' however I was using the unit in 'free' mode if you could call it that, and it just wasn't following the road with any degree of accuracy. It was sometimes way out over a long period of time not just a temporary excursion.

However, it now seems to have improved its accuracy greatly for reasons I just don't understand.

I've been using the 'base map' and will soon get the Mapsource CD and so will see how it performs in the next week or so.
