Had my Nuvi a couple of weeks now and the window mount has detached four or five times. Most disconcerting to have it trundling across the dashboard with me chasing it at the same time as driving! I've read a few threads re a 'new' style mount which is better than the 'old'. but I don't know which I have. Anybody got a description or better still a piccie? and where did you get the new one from?
