For some of us who have lost most of their hearing, I have found a way to finally hear the radio on my RT. If you have hearing aids that are Bluetooth capable, I found that using a Sena SM10 unit that can make your Spyder radio wifi with various electronics also will work with bluetooth abled hearing aids. I have Phonak and it was a simple job to "pair" them with the SM10. I can now listned to the radio in clear without background noise. I also had the unit paired with the Sena helmet speakers but the hearing aid hook up is much better........
