I am writing this post for Brian, but others may benefit from some of the information…..so why not make a post out of it.
Brian had a question about which intercom system was installed in his 2000 LTC. We met at the RTE in Centerville, Texas today and I was able to identify it as the J&M built BC3 Comm System. This post will apply to that system.
Brian was looking for an audio output from the intercom to use for some earphone speakers. After I left him I thought of one other way that he can accomplish that if he does not need a microphone…other than that he will need headsets. The option is to use this adapter from CycleGadgets and connect it to the headset jack on the left front panel.

If he wishes to go the headset route, Sierra Electronics is a dealer for J&M and has a couple different quality headsets to offer. Their headsets come with an upper 8 pin cord that is universal and will allow you to connect many different bikes by using a specific lower cord for that bike. In the case of the LT, it would be for a 6 pin system. The available headsets and cords also depend on the style of helmet that they are to be installed. Here is a link to the many options:

I use an open face helmet with the economy headset and lower cord…this one:

using the cord option of JM-HC PWY
That combination costs $90 for the headset and $21.50 for the lower cord
The difference between this and the BMW headset and cord is the length of the rider cord and shape of it. If the jack on the bike is located on the left front panel next to the Bike Computer, the cord needs to be longer and not coiled at that end. It then drapes over or under the handlebars so as not to interfere with them. I cured this problem by making a 16 inch extension cord with normal 6 pin din jacks and plugs bought at Radio Shack. I have this attached by an Adel clamp to the left bar. A Photo is attached. A better way to cure this would be to relocate the jack from next to the Bike Computer to the flat black horizontal panel under the left handlebar…I have seen some in that position on newer bikes.
Brian’s next question was about the CB radio. His LT has everything already installed, however the CB itself is missing. There were 2 different Midland CB’s that were used in that time period. One was the 75-830 and the other was the 75-820. Brian’s appeared to have the base that uses the 75-820. The 75-820 and the 75-822 are interchangeable. This one is still available online from a few places. Here is a link:

The link below will probably do more good than any of my help. It will take you to the pdf file that is the Comm System Manual.

I hope this has helped clear up things….if you have any questions please just ask.
