I have been thinking of upgrading my Garmin Nuvi 1300. It is very nice and I like the features it gives me but I think I would like to program routes. The 1300 only allows waypoints and not routes. When you program a destination, you can either choose between the fastest route or the most direct. All of the other information is just amazing but I think the Garmin Zumo 665 is the way to go......just awsome. It is intended for Motorcycles and is waterproof. You can also buy an XM radio subscription with it and get 170 digital radio channels to listen to while you ride. The mount is already compatable with my mount for the 1300 so I should be able to switch over easily. I power my Nuvi 1300 with an external battery which is equiped with a USB port and I can power my GPS for up to 14 hours. The battery is an Energizer 8000 mA Lithium Polymer battery. They also make a 16,000 mA version. Here are some links and pictures. For now I am happy with the 1300 and haven't decided to fork out the $800 for the Zumo but it's at the back of my mind and I know its the way to go.......in style.
