Watch out for vibration with this one
I have this mount on my Vulcan 1600 for the map10. It works Great!!! but.. The vibration killed the GPS unit after 29,560 miles, about 3 years.
Thats why I'm looking for something new now. Sturgis, S.D. is next month and I live in Fla. about 4,000 mi. Good Luck!!

Works Great, No Bicycle Mount Needed
Just a note because I found this confusing when shopping for a motorcycle mount for my Garmin eTrex Legend cx. You do not need to purchase the Garmin Bicycle Mount with this product. Just purchase this large rail mount adapter, and attach the GP mount adapter that comes in the box with your GPS device. That's all you need. Haven't ridden with it yet, but the large Diameter Rail Mount Adapter fits my HD Dyna handlebar great. Easy to install, GPS snaps right in.

this is the bike mount for the Garmin eTrex Vista HCx
If you have a Garmin eTrex Vista HCx GPS, do not buy Garmin's bike mount because it does not fit. Buy this rail mount instead to mount the GPS on a bicycle handlebar. The adapter that comes with the Vista HCx clips right in to this rail mount.

Unfortunately, this mount is not as secure as the mount Garmin makes for their Edge GPS units and it only allows you to mount the GPS on your handlebar, not on the stem.

There is also a small diameter version for thinner handlebars (like many mountain bikes): Garmin Rail Mount Adapter (010-10496-01)

Perfect!
For serious riders who have more than one bike this is perfect. My touring bike has the smaller diameter handlebar while my road bike has the larger diameter handlebar. I needed two adapters but only one mount. Great price too!

Great for most motorcycles
My metric cruiser has 32mm diameter handlebars and this fit just fine. If you're like me, you'll want to install an additional safety strap. If you intstall it correctly, you can still access the metal hook on the back of your Garmin and run a safety strap through it and around your handlebars. The only "real" issue is trying to touch that tiny button on the GPS while doing 80 mph (not recommended).
