I have become spoiled over the years having a GPS in my car. I'm considering buying an aftermarket mount to put my Nuvi on my handlebars. The only thing that's stopping me is knowing that it's just one more distraction that takes your eyes off the road, even if only for a few seconds. Knowing that, I have also considered adding a tank pouch and sliding it in there so if necessary, I can just pull over and check my route from time to time while stopped. Any opinions on GPS... good or bad idea ?
