I'm leaving on my first trip of the season Saturday morning and was planning to use a borrowed bluetooth dongle to listen to tunes on my Sena headset. As it appears all or most of the trip will be in rain (possibly heavy) does anyone know if I can use the hardwire from the Zumo to the Sena in the rain? Or do I risk damaging one or both units? I'm riding an RT with good wind protection but nevertheless it's going to be wet!
