I tried to install the latest firmware update for my soundtouch 20 series III, but I am not sure if it went to the end, I would need the reference of the update to check it on my system, could not find it on bose website
The latest firmware version for your speaker is 24.0.7 at this time. You can check whether your system is running this version from the speaker itself by following these steps:
You can also do this from the SoundTouch app by opening the menu and navigating to Settings > About > [Your SoundTouch 20].
I hope this helps!
