iNav Boss V2 iPod controller on the Versys
I attached my Boss V2 to the Versys this evening and used it riding for the 1st time.
The steering wheel mount is attached to the bars as shown and I attached it to the clutch lever with a cable tie so it can't rotate forward.
I may tether the actual unit so it can't bounce out of the cradle, but it's light and securely snapped in place so that seems unlikely. I'd tether it with a spare Contour video camera tether, which has a quick disconnect.
It's easy to operate on the bike when you can see it. I even used it at night. Might be harder at night if there were no other cars or streetlights. The white unit I have doesn't need a lot of light to see it, but with none, you might have to feel around to operate it.
