Except with a Quest, out of the box, your range in Europe will be limited due to the fixed memory combined with the big mapping tile sizes in City Navigator. You can use MetroGuide Europe (which retains the smaller tiles of earlier versions) when loaded onto the unit using MetroWizzz. The only downsides of this is the marginally more complex map loading process (it's a sort of Wizard led thing) and that roundabouts get, for example, "turn right" instead of "take 3rd exit" on the audio directions. However, a quick glance at the screen shows the correct exit if there's any ambiguity.
...are they water proof
No competition, a 2610 !!
When I updated to a Zumo 'which I love' I sold my 2610 and it was like saying goodbye to friend.
Bloody hell! I'm gonna have to see a doctor
