i use the the nuvi 1250, I mount it on either the windshield or the gas tank using the windshield mount. the only time i ever had an issue was when I pushed the unit out of the mount while trying to turn it on.
one feature the 1250 doesn't have is the ability to pick exactly what route i want to take - i believe that garmin motorcycle specific models allow this and i think the 760 does as well (is that correct?). does anyone know if the 550 allows this? If so it seems like a great choice, you can buy one for less tahn $200 delivered on ebay, it's waterproof, and it's solid state.
i checked the website, but i'm still not positive if it does this or not.
thanks - sean
