I'm sorry if this is posted in the wrong spot but was unsure where to post it. I am aware this is not actually radio specific but figured if anyone would know that someone on here would. I have a 1986 honda goldwing with driver to passenger intercom and Am/FM cassette radio and 40 channel cb that I am working on for my boss and it has an intercom system on it that uses 5 pin din style connectors. He is wanting me to wire in a 3.5mm 4 conductor jack to be able to connect to a droid cell phone so he can use the helmet mounted headset/mic to answer and talk on his cell phone so he doesn't have to stop and pull off his helmet to recieve a call as he is a business owner. The helmet set is a J&M and has a dynamic mic. I have wiring diagrams for the phone and helmet mic along with motorcycle factory wiring diagram. Here's the catch no matter what I do the mic won't work, I get sound from the phone to the helmet speakers but the phone mic is the only one picking up sound and not the helmet mic. I have been dealing with this for a few days and can't figure it out.:headbang Any ideas are welcomed.op:
