I emailed my revised schematic to Stark Avionics to have John check it for me. He sent an email back saying it was a mess! I took his suggestions and revised my diagram eliminating the two stereo pots while adding the 10K pot recommeded by Dynon to run the HS34 audio through. By eliminating the second pot the GPS496 stereo output went direct to the music input jack which also made the wiring less complex. GPS volume can be set with the software, which I hadn't realized.
The schematic pictures are not that great but you can get some idea of the complexity of the wiring.
