[QUOTE] I've got a Zumo 400 with inbuilt UK maps. Using a card from Garmin it will do full European maps. I'm very happy with it and would definitely go for another Garmin again. I wouldn't use a waterproof case because the Zumo 400 etc. are designed for use with gloves on.[/QUOTE] I'm not sure what difference that makes, unless they've got knobs & things on the edges to operate them rather than a touchscreen?
