Assume we're referring to using Kenwood FRS radios. UBZ-LF14 or LH14, for example.
I've noticed some online dealers seem to be stocking on that cable still, but my local dealers can't seem to order it as it's "no longer available" even though it appears in the catalog. So, snag one if you can. I have some of the other BMW cables; quality is quite good and prices are predictably commensurate.
An option might be to do what I did which is buy the mini and sub-mini male to male pairs in short lengths (6" or 12", for example.) Zip tie them together, and voila, instant cable. I even made a longish one if I want to stash the radio far away from the intercom.
I'm on travel for the next few days, so sorry for no pics to post, but it's a pretty simple concept. I sourced the cables from my local electronics store and I think they were in a Calrad package.
