I've never regretted choosing the TomTom. It is easy to update (plug into your computer once a week) and I can use it in any vehicle I happen to be driving. There are newer versions now, with slightly larger screens, and there is a specialised truck version, the 7000 series (typical reseller: http://www.tomtom-navigation.co.uk/). I did buy the Truck SD card for my GO730 and I always intended to write a review but never got round to it. There are limitations to the SD card, so I haven't used it much.
