Can anyone tell me what GPS reference TomTom units use?

I have TT on a PDA supplied by Vodafone (fundamentally a
HTC6500.) Quite often the position does not correspond with the
map. e.g. when driving the A1(M) around Ferrybridge the map shows
that I am driving across fields. Zooming out shows the road
(which is only a few years old) to be present, it is just that
the software thinks we are some distance east of it.

Prior to this PDA I had a Vodafone 1605 (HTC TyTN) and that had
the same problem, which suggests that the reference point for the
GPS calculation is wrong.


TIA

The road has probably moved. Install google maps and compare.

You must have a very old TomTom map, then. I remember my old TomTom
doing this around Ferrybridge in early 2006 but a new map issued shortly
after with the new A1(M) fixed this.

Tomtom certainly cannot be relied on to keep the maps up to date. They
have told me that it can take up to two years to implement changes.

I have given up on the map updates for now.

I should have thought the no-cost mapping and navigation from Nokia and
Google will put paid to Tomtom's business model anyway.
