What are the major differences between brands?

[shouldbworking]

Can anyone educate me on the major differences between the different brands of sat nav? Is there any significant difference on the functionality or is it just down to interface design?

I am presently liking the idea of a TomTom xl europe, but I have a half remembered drunken conversation with a taxi driver about the differences and why he preferred some other brand...

Anyway, beer please.

Hmm, thanks for the info. Ive just been reading the reviews in practical classics, and im stuck between the navman they list there and a tomtom europe.

I suspect ill probably get the tomtom as ive already used them and the interface seemed to make sense.
