My Garmin 305 just started swithing off when I going over a bump. When I switch it back on than everything is OK again until the next hard bump. Any question on what is the posibility of the problem. Garmin repair are taking about need to change unit.
I tried them all and the only one that I can recommend is the Assos Mille. I wasted a lot of money on Ascent, this is not good not even if you want to go cheap on your ass.
