Rainmaker, I have a motorcycle mount for a NUVI that you can have. It has the industrial clamp for the GPS and the standard RAM ball on it. You will need a handlebar mount or other type and a short RAM clamp. It's yours if you will PM me your address. I will send it off in the mail on Monday. I will be out of town this weekend, my son is graduating from Stephen F. Austin this Saturday!!!
P.S. I don't need this any longer as I found a steal of a deal on a Zumo 550. A guy at a ham radio swap meet had a box full of Garmins for $50 and this Zumo was in there with them. I asked him how much for the old bigger unit. He said $60..... I hem and hawed around for 10 minutes or so, then gave him the money.
Ride Safe out there,
Hay
