I have one already, haven't mounted or wired it yet though. The construction leads me to believe it is water proof. The flexible screen that you operate the touch screen through probably does reduce sensitivity (ha!) but I'm not planning on using this as my main gps. Secondary gps, phone and music (maybe). Hoping for reduced need to interact with it. With my phone plugged in the full power screen is pretty bright so I think I will be able to see it. Have to see if I just end up confirming TG's findings.
