OK. Although this thread is old and everyone probably has this information already, I just thought I would share my experience. At the International Motorcycle Show at the Javits Center in NYC last weekend, Helmetsounds.com, a reseller for Sena, UClear and J&M, provided this solution for me.
SENA SM10 DUAL STREAM BLUETOOTH STEREO TRANSMITTER - Converts the audio signals from the 7-pin DIN into a Bluetooth signal and transmits that to the UClear or Sena Bluetooth helmet setup. With this unit, all sources from the HD Infotainment system (phone, AM/FM, Satellite radio, etc.) will be available in your Bluetooth headset. Not sure about CB, but I don't care. It can charge and run the unit at the same time, so the battery will never go dead on you.
UCLEAR HBC100 PLUS - I chose the UClear Bluetooth helmet system because it doesn't use a boom microphone. It has tiny inline mics that hide under the helmet liner in the front of the helmet. I tested it and it works great. The speaker pads can mount inside a 3/4 or full helmet.
J&M SOLO HEADSET CONNECTION CABLE - Needed if you don't already have the 7-pin DIN connector available (needed for Street Glide or Road Glide). It mates with a radio connector inside the fairing. I drilled a small hole in the back of the left fairing compartment on my Road Glide and have it connected to the SM10 that I keep inside the fairing compartment.
STEREO JACK 7 PIN - 01161 (STEREO JACK 3.5MM TO 7 PIN DIN CABLE needed to connect to the SM10 via the J&M cable)
UNIVERSAL EARBUDS - LONG (from UClear) - I bought these because I have a half helmet with nowhere to mount the included earphone pads.
So, the trick is to pair your phone with the Harley Infotainment system, then pair the HBC100 and SM10 together. I tested the intercom and made several phone calls while riding 65 mph. The people I talked to thought that I was just talking from my car. The UClear system eliminates all wind and ambient noise such as my pipes. The whole set-up cost me $360 bucks but was well worth it. It was a game changer. Looking forward to my next road trip.
