I have the GARMIN Nuvi 360, (which isn't available anymore) and I like it. I built a USB power supply for it to operate from while on the bike, and had a little trouble finding a suitable plug with a 90* bend in it so I could put it under the clear window on my tank bag. The newer NUVI models have much wider screens than mine, and I wish now that I had waited a while before buyin mine. Oh well, you never know what's on the horizon. I also like that I can plug in an earphone, and wear it under the helmet for turn-by-turn navigation without having to look at the screen. Programming destinations is a breeze if you know the address, otherwise, you can program intersections within a city. As with all newer GPS units, software upgrades are available from the GARMIN website, and the unit just plugs into your computer. Comes with software CD, cables, cig lighter plug and windshield mount too.
