Noticed there are a few threads on people looking at setting up a GPS unit. Thought I'd just put up what solution I went with...if it helps ya, great.
Since I wanted a touring screen for the GPS, I went with the Zero Gravity 23-910...

I bought a car GPS, the TomTom XL Australia model. I got this one because a mate I went on tour with uses one all the time and it works great and costs one third the price of the bike version.
So, did not want to strip wires or get into the headlight wiring...basically did not want to bugger around with anything other that connecting into the battery or power socket. So I went with the powerlet USB harness to the battery...

Plugged into the battery and ran around side fairing. To avoid unscrewing panels and such, I used a thin wire to route around and in some clips that were already supporting other wires under the fairing up and around the RG slider bracket and around to under the seat and onto the battery....hooked on the usb wiring and pulled it through.
The TomTom XL uses a suction cup mounting bracket...seems to work ok. (The guy I went on tour with used it for 3000km on his touring screen and it held fast...in all sorts of road conditions...was very impressed)
Here is a view with the ZG tourning screen.
So....with the Powerlet connector it was a quick and easy install and while I was under the seat, I chucked in a battery trickle charger.
Have a great new year all...hope its a good one.
