The 20S is one of the best headsets out there on the market... hence why I purchased it, however when I purchased it, I had (and still have) no intention of ever needing to use the intercom functionality. I simply commute to work and wanted a full featured headset for FM radio/multi devices etc.
However, one thing I thought I could do (and am greatly saddened that I can not) is to overlay for example Stereo Bluetooth Audio and GPS alerts.
I think it would be great to have a firmware update that enables a user to select if they wish to disable intercom functionality and then allowed them to pair say the secondary bluetooth audio device they would like to overlay to the old intercom bluetooth module.
This would really be the icing on the cake to make the 20S a truly perfect device for the sole commuter :)
