I finally bought the JMCB2003-DU.
I have the BMW badged version on my '04 and run it through the BMW badged J&M comm system (commonly referred to as the BC3). I broke it into two tasks and approached them separately. Start to finish for each is a couple of hours or less.
If yours is similar to this arrangement, and since you bought it through BMW I suspect it is, then it shouldn't be too tough. The directions should confirm the below outline.
I did mine in two steps; the CB and the antenna.
For the CB:
1- remove the left handlebar cover
2- remove the left side-panel
After mounting the CB, run the cables down the handlebar cable guides. The hardest part of the whole thing is getting the relatively large connector ends through the slots at the base of the handlebars. Once you do that it's all down hill from there.
On the J&M comm system you simply plug the matching connectors together with the CB connector (only one connection). The CB had a second connector that does not, at least on my comm system, plug into anything. The last cable is the antenna. Run it in the space between the gas tank and the stingray and then down under the drivers seat and tie wrap it.
For the antenna:
1- remove the pillion
2- remove the top case
3- remove cover under top case
4- if yours is the same as mine, notch the panel for antenna bracket (it's a mirror of the radio antenna pattern and easy to do with a coping saw/dremmel etc.)
5- connect the ground straps
6- mount antenna and tie wrap cable
7- connect the two ends of coax cable toward the front of the driver seat and your done.
When I took the bike in for service I asked them to put an SWR meter on it to confirm it was tuned properly. It was without adjustment.
Good luck.
