It's an excellent Sat Nav. Clear, fast, great screen. All the latest TomTom features are there like live traffic (so it knows where traffic jams are and diverts you around them), lane guidance on motorways. It will read out street names to you and understand you when you speak destinations to it. It even tells you the weather where you're going and lets you Google search for amenities in the area.
The ability to just plug it into the dash is superb. You never need to bother about charging and it shows you ipod/usb music playlists on the screen.
It's supposedly a branded version of a LIVE1000, but.. for some reason.. many features have been disabled. You can add your own POIs but thats about it. Adding voices, custom graphics, custom car symbols, custom start-up screens have all been removed. Everything except POI addition has been removed. You are paying a premium price, for reduced functionality.
The MyTomTom updating software is awful. It doesn't work on IE9 unless you run in compatibility mode and any map or firmware updates take AGES (we're talking hours) and have a tendancy to crash at the last minute.. bricking your TomTom until you successfully run them again. TIP: Shut down EVERYTHING else on your PC and connect the TomTom to a highspeed USB port at the back of your computer not through a hub or extension.
And the TomTom gives you directions on the display in your dashboard (where the mileometer is). Except in the UK it displays these in km instead of miles. This is a bug and doesn't seem to be being fixed. Tomtom says its a FIAT bug.. FIAT says its a TomTom bug.
If you can live with the hassles of updating, the limitations of the add-ons and the bug... it really is a fantastic Sat Nav.
