Yes. I see no reason the Universal unit they have for the 1500 wouldn't work. The only place it plugs into the 1500 system is between the rider headset cable and the rider headset. The owner of J&M told me they are discontinuing it in I think March of 2009 though, so if you want it, get it soon. Here's the part #.Is there anything similar that would work to connect a Bluetooth phone to a Clarion II? I have an 81 GL1100 but am installing an 82 Clarion II with CB, Cassette and Intercom during the rebuild. Being able to use my iPhone also would be great.
