Does anyone else have a problem with the sound level of the music through the Sena being too low and then the when the phone rings or calls are answered, the audio levels blow your ears? This happens to mine when I try to play music through the 3.5mm jack and through the bluetooth on my phone. I have to keep the Sena turned to max and my music devices cranked up to near max to be able to "decently" hear music.
I was going to buy a bluetooth dongle for my Nuvi since the Sena won't recognize my Garmin's bluetooth profile, but didn't want to invest anymore money if it was going to still be the horrible audio level. Anyone else use a dongle to pipe in music with good results?
