First of all, you are about to get about 7,000 emails telling you that there have already been 7,000 threads covering this exact topic. I don't know much about the 2610.
Try calling Cycoactive (see cycoactive.com) they sell garmin products, and offer several motorcycle specific packages to suit you needs. I just got done using my 276c to go down to California and back, and I love the thing.
