RE: 20S- Purchased June 21, 2015 Wife and I out for vacation. Bike- BMW LT, Connected to 20s: 1. Garmin 660LM 2. Iphone 6 3. Wife’s SMH10 4. (wish Escort would work!!) COM was really good until- the Garmin came on. It was super loud. Very distorting to the speakers. I turned it WAY down. Then I could not talk to my wife. I had to turn the volume way back up and she would have to hit her Intercom button on the SMH10. They we were fine till the Garmin came back on….VERY LOUD. Painful. I went into the 660LM menu, VOLUME. Garmin Message is to adjust the volume with the connected Bluetooth device, ie. 20S. I then went into Garmin menu to MIXER and adjusted all mixer levels to 10%. This did not help. So, my wife turned off the SMH10 as I could get navigation and talk to her. When the Garmin announced, it was super loud with distorted speakers. Turned down to an acceptable level. The next time it announced, it was again super loud. Turned down again. Repeat- Repeat- Repeat…!!! Useless and painful to the ears. Also, it seems that when in COM with wife, we have Bluetooth un-pairing and she has to re-push the pairing button. Again..aggravating. Last week before we left, I connected both with the SENA software to updated all firmware as this has been an issue. At times, I think we loose power and have to power from bike- even though they just came off the charge less than an hour before. So, what to do????? By the way, I sent request into Sena via their Help Desk and via email. No response for almost a week. Have they gone on vacation?
