I owned this a few years ago, and when I sold my F800GS I sold the NAV to a mate who had a F800GT.
He barely used it and now has a NAV6 on his 1200RS - he's now emigrating to Spain!
So it's for sale!
I have loaded the latest MAPS on it, and all works as it should
Please note that this has a small memory, so only holds NW EU maps at one time (UK, Germany, France, Spain etc).
My understanding is that there IS a way to put all maps at once on an SD card, but you would have to verify for yourself.
