My K1200LT (03) is at the dealers (for two weeks). I had the com system added about two years ago and after some frustrating false starts and help from J&M it has worked well until recently. I broke the electrical connection on the antena, didn't realize that I had to undo the allen screw on the base. The dealership installed a new antena and at the first opportunity to use the CB on a ride with my brother on his RT, he could hear me but I couldn't hear him. I can hear, in my helmet, my Garmin 2730, the com system radio and ipod. The tech at my dealership is frustrated and told me that they don't get training on CB's. I called Sierra of Ohio and the tech their suggested that it might be my brother's CB not transmitting, but the local tech ruled that out using a CB in the shop. J&M has not responded this time to several e-mails sent by the dealership. I have read on this forum that CB antenas have to be tuned. Should I have the dealership put it back together and bring it to a CB professional? I also have an 06 R1200GS with a J&M CB which is fine. Thanks.
