Small handy bike mount to avoid that ATV twisting of the wrist does not come accidentally press the buttons on your Garmin. (Enough infuriating to see that your system has been halted in the middle)
In addition to playing in front of you bike on the bike stem is still cooler than letting go of the handlebars to look at his wrist!
A small additional investment vettetites consider for our friends who own the GARMIN FORERUNNER 405.
