As I have a car sat nav I couldn't justify buying one for the motorbike too so thought I would give this waterproof holder/mount/case a try. I also bought a waterproof power socket to run the sat nav from the bike's battery. It was straight forward and quick to fit on my FZ6 Fazer, the only issue is that I won't be able to use it if I have my tank bag in place as I have had to position the unit to one side of the handlebar and it therefore hits the tank bag. Definitely worth considering though, as a cheap option if you already have a car sat nav. I found that I could still operate the unit screen through the plastic cover which I wasn't expecting!
