The entire Bluetooth intercom function of the Sena 30K is fraught with problems.
You can't have intercom and any other audio input from GPS, music, phone etc. The multitasking function does not work.
If you try to listen to music with Bluetooth intercom on and then toggle the button to turn the intercom off, then the intercom function won't come back on. You have to power off both headsets and start over.
There is no way I can find to block out wind noise other than turning the intercom on and off, and when you try to use it in that manner, it usually fails to turn back on.
The only way to use an intercom with this unit is through the Mesh system. The bluetooth intercom function on this unit is basically unusable.
