I have a bar mount from Ram to use my 2610. I have used it on several bikes over the last few years starting with a GPS V. It also doubles as a camera mount.
Do you Luddites ever resort to maps?
I like the fact that I can mark where I am staying, ride back roads to my hearts content in a strange place without fear on getting lost, I just tell the GPS to get me back to where ever I am staying. I have detailed back road maps for anywhere in the country, with directions to the nearest gas and food.
God forbid it ever happens, but if I ever need it, I can phone my exact coordinates in to emergency personnel in the event of an emergency. Beats the hell out of "I'm not quite sure of the name of the road I am on."
It is a tool, not a crutch or amusement device for me.
