I’ve got the tomtom western europe app (when I bought it, it was a different app in the appstore)
I bought mine when it was on special offer, so got it for £40, but that was 3 years ago now.
It is great as a satnav – works exactly the same as a standalone tomtom, with the added benefit of google searching for POIs. Plus the usual bonus of not having a separate thing you leave in your car for people to nick.
Worth having a decent cradle for it. I found mine struggled for signal (not to mention being hard to glance at) when I had it sat down next to the ashtray. You’ll want it to be plugged in too, as it eats the battery when tomtom is in use.
