Hello everyone,
The one thing I would love to see on the 920 would be a more reliable ETA. The algorythm would be so easy to update by the TomTom Engineers, but nobody wants to do it. An example would be to drive 700KM at 100KM/hr doesn't take 14hrs. It takes 7hrs or less if you're going above the speed limit of course. If you have all the satellites establishing your speed, they can easily establish a time factor.
Other than that, it is a great piece of technology!
Take care everyone,

The new maps with the latest firmware DO provide an improvement on ETA. A factor in the estimates is the average speed of a road and time of day estimates. With firmware 815(I think that was it), they added support for an advanced IQ Routes which, when used with the 825 maps, has a time of day average speed, not just a day of the week average speed for roads.
Now, you look at 700KM and 100KM/hour as absolutes, without taking into account the roads involved. If you have an open road with no other cars, then yes, you would be looking at only 7 hours, but if the route has the potential for traffic, then it MAY take quite a bit longer. As I said though, the estimates are based on information in the maps you use, so if you never update your Tomtom with new firmware and stick to the old maps, you may find the accuracy a lot worse than if you fully updated.
