Picked up a 2003 1800 about a month ago with about 21k on the odometer. I noticed where the PO had installed a CB in the trunk. On my 1500, my wife and I had used the intercom from time to time, but always liked the Sena Q3. I decided to try out the intercom on the 1800 and nothing works. I know the headsets work, tried them both on the 1500 & they're fine. I've checked the settings on the bike for intercom and it's all set right. On intercom, we have nothing...no intercom, radio, CB...nada. It all works when in regular mode. Is there something under the seat I need to be looking for that might have accidentally been left unplugged?
