When I said 550 I meant to say 590. The 550 is really old. Unfortunately the options come with the well built models. You could go with a much less expensive non motorcycle Nuvi. You can find some good comparison charts on line of what the diff models offer. I think the 590s are going for just over 7 on e-bay or Amazon, the other one much less. You will also need two tire monitor sensors if you want that and it is good to know your pressures.
