I've tried Tomtom, Garmin and one I shan't name but was expensive and less than useless, I want a GPS that is large enough to read comfortably with my "poorer" than it has been in the past, ...65+ eyesight. When I'm on the road and driving I want a GPS that is easy to read and accurate, a Motorhome or large truck is ideal, but they don't always do what it says on the tin. I have been in some very, very tight spots. This has been recommended Garmin StreetPilot 7200 if any one has experience of this or others and has views like, does it work? Help with this will be much appreciated. UK and western Europe is ideal.
