I've had my TomTom GO LIVE 825 Europe for over a year now and took it abroad a couple of times last year to France, Belgium and the Netherlands. It was fantastic the whole time, great for general navigation around towns and cities, finding hotels and parking. The live traffic information really helped out at times, like when we were trying to avoid the worst of the traffic leaving the Belgian GP. It's not perfect, the updating software on the PC is a bit weird at times and I find the menu interface a little clunky by smartphone standards but once you're driving along it's excellent. The windscreen mount works well and is easy to position within reach in a 350Z without blocking the view.
It's what TomTom call 'Always Connected' as opposed to their cheaper 'Smartphone Connected' variety so there's no data charges on your phone which is ideal for Europe. It's now been superseded by the TomTom GO 5000 for around £250 which has a new interface and lifetime map updates and live traffic information. Mine is still available on Amazon for less than £160 but I have to pay about £40 a year from now on to keep the traffic information working, mine came with lifetime map updates but not sure if that offer is still available.
