I moved my Zumo 550 and Autocom L-1 Logic from my RT to my new GS and everything went well except I no longer have voice output over the phone. I can hear the phone just fine, and the intercom feedback of my voice is loud and clear. I looked at the tank bag on the old RT and there were two holes for wires from the Autocom to the Zumo, but now I'm down to one. I'm assuming there is a wire missing from the mic input on the GPS to the Autocom. I've looked everywhere on both bikes and it's lost. In looking at both manuals this option is of coarse missing. Does it plug into Aux 3 port on the Autocom. If anyone else has this same set-up please confirm I've not really lost my mind. If there is still the part number tag on the wire that would be great as well.
