So I'm getting ready for a 5 day, 4 night trip.  Picked up a few goodies.  1st, I got a RAM gps mount for my Garmin Nuvi 260W.  Solid piece of equipment.  Only one negative feedback.  I had to cut this plastic piece that got in the way of the mini-USB plug. Cable that came with the GPS had a right angle mini-USB connector.  If it had a straight out mini-USB connector, it would not have been a problem.

Besides that, the mount is solid.  I tried it out on my 30mi commute to work today.  Averaged 85mph.  Nothing moved or shifted.  No vibration.  If I was planning to use the GPS more often, I might have opted to go with the more expensive handle bar clamp mount (that's the one that mounts to the existing handlebar clamp hole).  Since I was only planning on using it for this one trip, I opted to get the cheaper option which just wraps around the handle bar.  Total price: $25

More expensive handle bar clamp option (replaces one of the clamp screws)

2nd thing I picked up was the Nelson-Rigg CL-1030 tank bag.  With the bag extended/enlarged, I was able to fit my 15" macbook pro at an angle.  Fitment is great.  Contours nicely to the sloping tank.  The bag is connected by two straps and 4 buckles.  One around the front of the frame and one under the seat.  Getting gas means taking off two of the buckles and lifting the bag out of the way.  I could have gone with a more expensive option of a bag that mounts to a bike specific gas cap adapter.  But that would be $300+ where I only paid $100 for this bag.  Tested it on my commute to work.  Fits great, doesn't block the gauges at all.  Overall I am very happy with my two purchases.

Oh, the GPS is powered by the battery tender using this

				     Thanks for posting this info. It so happens that I'll be heading on a 7 day trip from San Fran up the coast to Canada and this helps me to decide on what i need in terms of GPS set ups.  [thumbsup]
			
			
			
				And here's a cheap way to keep your GPS dry.

				LOL.  I laugh now.  I'm sure once it rains, I'll stop by the nearest convenience store and pick up a pack of condoms. haha.
