Just 6 on the ago I bought this Garmin unit and before buying my C600. Now I come to mount it and set up power side. Mmmmm - I will use the RAM brake reservoir mount and am not unhappy about that. My challenge comes on the power side. I was hoping to just use the accessory socket when I was on a longer trip rather than the provided hard wire cabling but there is a problem. The USB port on the back of the Zuma is blocked when you put the unit in the provided motorcycle Zuma mount. Has anyone found a way to power a 390LM with the accessory socket in the left box rather than hard wiring it?
