I have a Sena Sm10 bluetooth transmitter for sale. I installed this earlier this year to allow me to listen to the Road Glide's radio and navigation via my Sena Smh10 bluetooth receiver. Included is the cable that attaches to the radio unit and the Sena adapter that connects the 7 pin end to the Sm10. I threaded the cable from behind the fairing to exit next to the head. I mounted the Sena with two sided tape to the inner side of the fairing, next to the storage bin. Everything works great, includes everything in the photos. Some wear on the side of the unit itself, from weather. I paid $135 for the Sena, $25 for adapter cable, and $50 for audio cable itself (Harley part sells for $70). I just bought a new Schuberth helmet which has bluetooth and an Fm radio receiver so I don't need this device.
Yours shipped for $100.
