Just installed a 650/750 in my Cirrus, remote transponder and remote 35c audio panel. Despite the 8 "synoptic graphical selection" modes, there is no pilot isolate. When flying with wife and kids, I have to group her as a passenger, which eliminates the option of different audio options for her and the kids. Had to dig out a couple of old audio adaptors for the kids and unplug their headsets so they are not forced to listen to the Oprah channel. Reached out to Garmin to see if they were aware of this, and was told to read the manual. Am I missing something, or are Garmin engineers dopes??
