For those that are interested; here is a full demo of the dual purpose climate control, fan control, audio source, track up and track down buttons.
When the audio is muted the source, track up and track down buttons act as fan speed up, fan speed down and on/off/auto for the climate control system. In the video you can see the fan speed change (upper right corner) while on the media page of the infotainment system.
Let us know if there is any feedback for the control strategy that we have implemented. This feature can be toggled on or off for those of us who like to change audio source when the audio is muted
! We have some exciting features that will be coming to fruition in the near future and will keep the forum posted on developments when they are ready.
