I got a handlebar mount for my Garmin GPSMap 60CSX. I didn't even know they sold one until I saw it while flipping through amazon-dot-com a couple weeks ago. I was so proud rolling up to volleyball with a new GPS console on my Nova.
I need to change how they taped my handlebar tape, though. There's only room for one gadget on each side right now, and I still have several toys to put on there, like my incredibell, headlight and video camera. (It isn't my commuter, but my Nova is the bike that I ride longer distances to explore the back roads.)
