I’ve been using Tomtom Navigator 6 on my Orange SPV M600 with a cheap bluetooth gps receiver I bought on ebay, and it has been quite impressive in what it can do. Only hassle I’ve had has been with the audio on my cheap holder for the car.

I was quite interested to see an article on the BBC about how they check the data for the maps behind the likes of tomtom, which involved a couple in a big orange van with cameras.

It’s quite interesting to see how surveying works in the modern age.
