It turned out that the nav section's volume was not completely turned to silent. The volume knob was just a fraction from being closed, so I was very surprised that this fraction totally blocked the COM audio to my headset. Valuable lesson learned. What I would like to do next, is to find a way to minimize this effect. Any ideas?
