I have a zumo 550 wired into an autocom easi-plus 150 duo. I took the bike down to the lake district at the weekend and got absolutely soaked. i now have a loud crackle coming through the autocom and the voice direction / music is now very low through the zumo. I've unplugged all of the leads and there seems to be no sign of moisture. The main unit seems dry and is under the seat in the tool tray, hard wired into the back of the power socket. I know that it may be best to let the bike sit in the garage all week to dry out, but is there a quick fix or somewhere to look first ? I'm also keen to stop this happening again, as it's bloody annoying. Any thoughts ?
