    This isn't what is happening to me. I'm not getting any beeping noise. I'm getting dropped audio. It's definitely not a collar or anything hitting the wheel. Thank you for the suggestion though.

    Done. Thank you.

    If it's only happening when closing your helmet etc.. I wonder if its kicking in voice command mode. I think you can adjust the sensitivity in either the phone app, or on the PC. When it does happen, try turning the volume up and might here it repeating "Say a Command" or just say "Cancel" and see if you get audio back?

    Hope SENA can help you out.

    Good thought. I had the same thought and turned off voice command altogether. No change. Thanks!

    Have you tried turning of the touch commands? And also check if you don't activate the bottom switch. This activates the voice control.

    It is recommended to update the firmware on your 20S / 20S EVO to the latest version if you use an iPhone as this update improves the compatibility of the 20S / 20S EVO with the iPhone version of the Sena Utility App.

    My battery seems to be playing up. Appears to charge ok but dies straight away. Unit runs fine plugged in but the low battery warning starts up straight away and drives me nuts. Now what?

    IIRC, there are videos on youtube about putting in aftermarket batteries. Wait... found one; there are a few out there. Note that I have not done this myself. Text below the video on the youtube page lists the battery type.



    FWIW, I was an early adopter of the 20S and mine continue to soldier along. I just completed an 1171 mile long weekend ride down into PA to ride fun roads and hang out with friends and my 20S worked flawlessly. I used it primarily for radar detector alerts and spoken directions for following backroads routes I made (sometimes muted, sometimes on). I also have it set up to listen to (iPod) music from the same BT transmitter that sends the V-1 signal, but I never turned it on this ride.

    I had a similar problem. Contacted Sena and they replaced the unit for free.

    seems the Sena guys have abandoned support for the SMH10 when using with iOS 13
    quite a long thread on Sena support forum, but crickets from the guys at Sena

    My wife and I both have the dreaded "say a command" prompt on repeat. I've tried turning off voice prompts, updating firmware, turning off/down sensitivity, nothing works. I believe it's not in the unit itself. We both have two helmets with mounts for the S20. It is only on a particular mount that this happens. Essentially, for each unit, it works correctly on one helmet mount and not the other. The defective mount on hers came with the unit and the defective mount on mine was purchased as a lone mount kit.

    The "say a command" prompt only happens when we are not connected to communicate. When our units are connected it goes away.

    Anybody else have this problem and find a solution?

    I get the "say a command" thing when riding in high wind (cross-winds yesterday). It would be nice to turn it off...

    The Voice Command system can be disabled through the Sena Utility App or the Sena Device Manager by changing the Motion Sensor Sensitivity level to "Disable".

    Went to turn on my Sena 20S Evo yesterday: Nothing. No response at all.

    Plugged it into its USB charger (with a verified working cable etc.): Nothing. No Red light, no anything. Left it plugged in for 24 hours "just in case", but this did not seem to do anything.

    Talked to Sena's service people today and they sent me instructions for a "Modified Reset":

    Please find the Modified reset to do and then follow with the Troubleshooting, allow to charge over night and then retest.
    Let me know how you go.

    Modified Reset
    1. Connect your Sena to a power source (that you are know works) using the USB Charging cable provided in the pack.
    2. Using the end of a paperclip, gently press it into the Fault Reset hole, on the rear of the Sena unit, 5 times in quick succession.
    3. Unplug and then replug the device into the power, allow to charge for 15 mins.
    4. Now please power on your Sena by pressing the Jogdial and the Phone button for 1 second.


    Followed the instructions as advised: Nothing. No indication of life at all.

    Followed the instructions again: Nothing. No sign of life.

    Charging overnight and will then retest in the morning; but at this point I have very little belief that it will be anything other than completely dead.

    The unit is about 18 months old, so it still covered by the Sena two year warranty.

    I only use the unit to listen to music and receive voice navigation; both of which are supplied by my Garmin Zumo 590.

    In the lead up to this failure I had noticed two changes in the behaviour of the 20S Evo:
    1. The battery would hold charge for a decreasing amount of time. When originally purchased the unit would hold full charge for several days. After 18 months of ownership if I charged the unit fully upon return from a full day of riding the Charging light would, after a reasonable period of charging, turn from Red to Blue, indicating full charge. However if I checked the unit the next day, or the day after, the battery indicator would only flash 3 Red on activation, sometimes it would only flash twice if I had left it for a few days.
    2. The battery originally lasted all day when purchased. After 18 months I am lucky to get a full day of riding out of it.

    It's been my experience with the Sena units is that they need to be plugged at all times when not in use (at least when possible). Once the battery completely discharges and goes flat, you're pretty much done. While not necessarily recommended by SENA, you can get aftermarket and replace them yourself.

    Hello. Please notify our Customer Service agent in your ticket that these steps did not provide a solution and that you would like to start the warranty replacement process.

    I will be doing exactly that today.

    The service agent requested that the unit be charged overnight after performing the modified reset. I have done as requested and, as expected, the situation is the same.

    It is comforting that Sena stands behind their product and I am very glad this happened within the warranty period.

    Regarding the comment
    what is the Sena view on this?

    Whilst it is good that Sena offer a good warranty service I would like to ensure that I do everything I can to keep the unit in as good condition as possible for as long as possible.

    There is conflicting information about this specific issue ("over-charging" vs. "under-charging") with some users claiming that the lithium co-polymer battery in the unit can be most easily damaged by charging to frequently!

    Any advice from Sena regarding the correct way to maximise the life of the unit would be appreciated :nod
