I use the Garmin 2610, and RAM mounts from GPSCity.com and a taper lock kit available Tucker Rocky, part no 34-0355. The RAM mount kept the gps and radar detector firmly mounted to the bike when I decided to get off the bike in Missouri, unfortunately I was doing 70 mph, when my brain stopped functioning

If you like pictures of the mounts, just message me, and I'll get my lazy ass out to the garage and take some pictures
