i'm so displeased with tomtom i'm not giving them any of my money for maps
I've just found out that the version of TomTom used in the Mazda is a beta version.
The latest release version of the fireware (called NavCore by TomTom) is 9 on a lot of the latest devices.
The version used by Mazda is version 10, and it hasn't been out that long.
I reckon there are a lot of bugs which might be leading to your problems stromdriver.
I still stick by non-beta releases of TomTom being the most accurate devices on the market. They're still the leaders (everywhere except US), have the largest traffic coverage (except US) and have the most users (outside the US).
I still can't see a better in car GPS on the market in Australia at least.
Once they iron our bugs - it should be flawless.
Regarding maps....
If you're having issues with maps, then you should complain to the map providers - not TomTom.
I'll continue to reiterate - TomTom package up the maps given to their by the US map provider.
They do such a brilliant job updating maps in Australia that I can't see why you would have an issue in the US.
Although I get the feeling that TomTom turns its nose up at the US market for some reason.
To illustrate the maps exact - Australian maps are produced by Whereis. They have a set version they provide to all GPS manufacturers. TomTom has it installed within days... not weeks.... not months.... days of it coming out.
There are some GPS's out there that don't have roads that are 3 years old. Where as the TomTom (on my iPhone at least), has new roads on the map as soon as the map maker has provided them.
TomTom does not make maps for the US or Australia.
