I have an Edge 705 which I use and love and picked up a Nuvi 205w recently. The Nuvi has a bike mount which I ordered and haven't received yet. I'm curious about whether it's viable or not on a bike specifically in weather. The idea of a huge touch screen is desirable but I'm unsure whether it's a distraction or not.
Also the mount concerns me. Basically the unit mount is the same it looks like to me. It's not real difficult to remove my Nuvi from the car mount and I'm thinking a decent speed bump or pothole might have the same effect.
