Newbie MC Navigation.. Need Help..

[mnm2008]

I have a FJR that iam starting to use more.. Never had a NAVI on my MC.
Wanted to get Zumo, But i could not convince myself yet to shed those $'s
I recently acquired RX-Q with a Sena SMH10; so Bluetooth is Important feature to have.
I would like to use NAVI for palnning routes with GPX files..

Having said that - Does anyone have a NUVI unit with a good mount and weatherproofing or could recommend?
Just to put things in perspective - I ride 1K~2K Miles every year :); But would like to start taking some weekend trips soon and put more on the odo.

NUVI/ZUMO or something else..
