    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?

    Hopefully this can help ... I have the Zumo 660 and 20S, along with an SM10, iPhone, iPod and Valentine One. I have a riding buddy with a 20S and we use the intercom function. I ended up configuring my system as follows:
    - iPhone paired to Zumo 660
    - Valentine One and iPod wired into SM10
    - Zumo 660 and SM10 paired to 20S

    Screenshot 2017-06-04 10.56.50.png

    To get the Zumo 660 volume/distortion under control, I had to go to the Zumo audio mixer without the 20S in range (if the Zumo "sees" the 20S, it disables the Master volume control in the mixer). I set the Master - 20%, Navigation - 50%, Media - 50%. I found that without getting into the mixer, adjusting the Master didn't seem to help the distortion or volume from the Zumo. I also had to be sure I was adjusting the Zumo volume while it's transmitting, otherwise it was just turning down the Sena 20S overall volume.

    By the way, I've not been able to get the radar to work w/ SM10. Ipod is OK, but radar is only a click...which is super easy to miss. Sena says the SM10's inpty to headset is lowest priority. It needs to be #1.
    Can't figure why Escort only clicks. It is fine w/o SM10, earphones or via speaker.

    The radar detector audio needs to be plugged into the AUX input on the SM10. An audio signal on that input will mute the AUDIO IN signal. A radar alert from my Valentine One shuts down the music coming in from my iPod on AUDIO IN.

    Did that. Tried in both ports. Sena had no suggestions. I am thinking of wiring a resistor inline to see if the Escort is too hot.

    Interesting, it works as advertised with my Valentine One (Remote Audio Adapter). Does the Escort have a headphone out or is it an external speaker? If it's the latter, you're probably right ... too hot.

    has 3.5mm earphone jack...also internal speaker...
    Fairly loud speaker, but not enough to get thru helmet and earplugs/phones.

    I used the jack to feed Autocom. Also thinking of a Blu-tooth dongle to see how Sena deals w/ that,

    I use a BT xmtr dongle for my escort, made a mono-stereo cable/adapter. (the escort is a mono connection and dongle is stereo, I get the radar audio in both helmet speakers). Use Multi-point-Pairing (A2DP) for the dongle HFP for your phone.
    Im looking at some of these threads again to explore my options and sell my POS Zumo 660!

    I recently bought a like-new 20s and have the 1.7.7 firmware installed. And although I need some additional real world tests I believe it may actually work without having another device (sm10). I mean, if this keeps growing aren't we going to look just like The Borg?

    apparently sena listened (Not Garmin) and the 20s accepts PIN #1234 when pairing as 2nd phone.
