TomTom 910

The new TomTom GO series look better than the old. The software has also been upgraded and is a definate improvement, especially with the TomTom HOME Windows software which automagically manages updates of both the GO's software and content (i.e. safety camera database).

The navigation software has been improved, and if it knows the speed of the road warns you when you're breaking the speed limit and flashes when you're very over it.

The 910 has complete maps of Europe and the US and can do all sorts of music and picture bits and works with an iPod.

The major criticism is that accessories you might have for an older version, don't work with the new one.
