I own a Garmin Nuvi 200. It's a low end unit that I got free for opening a discover card account (this was several years ago). Anyway, I don't use it while I'm riding. I pull over and fire it up and then get my bearings. Mostly I use it when I've gotten myself lost in the middle of farm country and I'm low on fuel (bike food or people food). It's great for finding the nearest fuel stop. And now that I've wondered off the point let me try to get back to it....
You should think about how you want to use the unit. Here's some things to think about.
1) Do you want bluetooth? I would probably use my unit more if I could leave it on and have it talk to a bluetooth earpiece. Even in the car I usually listen to it more than look at it. With the helmet, motor and wind sounds you can't hear the gps without an earpiece
2) I plan most of my trips on google maps because it allows me to avoid roads I don't like (interstates, roads with bridge construction, roads that I know have lots of lights, etc). My garmin unit will not allow me to upload my google map with it's waypoints. So my point is... if you like using some piece of software to map out your routes, make sure it's compatable with your GPS.
One idea for mounting the unit is to get a tank bag with a clear plastic pouch on top. Usually used to hold a map. The gps will slip in there. It's also nice because most tank bags have a strap or a handle so when you get off the bike you just grab the bag and you got your gps, cell phone, wallet, etc
For power, on my 2003 one of the previous owners popped out the reflector on the right side by the tank and installed a cigarette lighter. I use it to charge my cell phone in the tank bag but it can also be used to power a gps.
just my 2 cents.
