Look what I did...
(it actually sits right under the gauges, even thought it looks like its up high)
(with the gps removed)
Im really happy with the way my idea came out. I used a garmin nuvi 1300 with ram mounts and an extra power cable. So while finishing my valve service I ran a power cable up to the handlebars, and installed a handlebar mount for the garmin.
The nice feature of the ram mount is its twist lock, so when your off the bike its a quick removal and you can put the whole thing in your pocket and all that is left on the bike is a small plastic piece.The install took about 5 mins and the mount only cost 20 bucks.
