I have a Zumo 660 which is hard wired to an Autocom SPA. It was working fine until today when I went out on a run. It powers up OK when on the bike mount, but the sound comes from the built in speaker rather than through the autocom. I have checked the connections which seem OK. The autocom appears fine and works with the bike to bike radios. This leads me to think there is a fault with the mount or the unit itself. Anyone else had this problem or any ideas on how to solve it?
