Well I did my first ride with the Garmin Montana 650t on the weekend and what a waste of time even taking it on the bike.
The first little bump it went over, it just turned off and re-started again.
This went on for the first 5klm of riding so I turned it off and left it off.
Obviously was not ment for dirt bike riding...maybe smooth dirt roads only. I have not done anything to the unit besides mounting it. I have not modified the battery or anything.
Heres the vid.
