Where can I get one? Ram mounts seem to be the way to go. You can get them cheap at Amazon but for some reason they won't ship to Canada and the sponsors here don't seem to carry them. There are two different styles.
I use my Nuvi for navigating in my new city and for Geocaching occasionally.
BTW Ottawa is the best as far as being bike friendly. Trails everywhere! You can smoke across town and see mostly trees and fields.
