The Zumo line of devices have many users who a GPS enthusiasts. I was surprised that there is no dedicated forum for Zumo. What is the best place to discuss them?
Afraid there isn't a forum for any 'on the road' devices. They've been asked for but they're not available yet. If you have issues with installing maps, Basecamp, Express etc post in the relevant forums. For specific device issues please contact Product Support.
