I think the drying out option is a good idea. If you know what you are doing and not worried about voiding any warrenty which ay still exist on it, take the back off, there are four screws, and just leave it open to dry in a warm place for a day or so. My handset had one button which used to get trapped under the plastic fascia, and effectly trick the mount to think I'd get my finger stuck down on it (I think it was the zero button). Now I know to just make sure I don't apply force at an angle to the keys and push straight down and it no longer gets trapped. Power is the likely error. Does you mount have an LED to suggest when the power is on or not. Watch the LED and fiddle with the mount and leads and see if it flickers; I suspect it will do. There are various fixes, but the cheapest and easiest is to tape the power lead at a couple of non-moving places to remove any slack so the power socket doesn't wiggle in the mount. If that solves the issue, get something like this to clamp onto the lead to remove the slack: http://images.cableorganizer.com//panduit/high-bond-adhesive-cord-clip/heat-stabilized-nylon-cord-clip_sm.jpg James
