This happens when the road, in real life, follows a different line to what is in the map data. TT will try to get you back on track until the road agrees to the map.

Or when the GO loses sight of enough satellites to get an accurate fix. If this happens frequently - because, for example, you drive a lot in city centres with tall buildings, or have a heated windscreen, you may benefit from using an external antenna.

I think that is more to do with the software. Other people I know who use TomTom, report the same thing happenning to them. I think that TomTom is a little quick to change your position away from the route. Since GPS has an inherrent inaccuracy (regardless of the number of satelites fixes you have) - it can be fooled into thinking that you have moved away from your route.
Conversely, CoPilot (which I use) is perhaps a little bit the 'other way', in that it can take an age when you do deviate from the route, and sometimes even fail to recognise that you have moved to another parallel road.
So it is probably a case of TomTom being better when you do move away from your route, and CoPilot being better when you don't. Unfortunately, each way of working has a downside too. |

I find quite the reverse. It will always try to snap to the nearest road. There is one place where I go, where there is a new by-pass not yet on TTG's map. When I drive along it, TTG hangs on to the old road for a couple of hundred yards before suddenly jumping into the middle of a field!

| It may well be that it is a little more reluctant to jump when there is no road for it to jump to. The situations I have observed were all where there was a road to jump to. |
