OK.

The nav computer does not have a connection to TELON on the harness.
Indeed.

Looking at the wiring diagram, it seems the TV Tuner is also using NAVNF for audio, would I be right in sayng the TV can create audio while you browse the menus?
Yes, I think so, I'd need to double check that.

The TV has it's own audio in to the radio.

In that case maybe it does work on detecting audio, as NAVBUS does seem to bypass the video module.
At a guess, I's say that the nav has a permanent (internal) bridge within the radio and when the nav outputs a signal (a voice command), then its just piggybacks the audio, the amount of "mix" is set-able via the set menu and this must have a similar effect as a reostat on the (mute).

hmmm, just a thought, I wonder if one could pipe an audio source directly using the nav input pins (in the smaller 12 pin block), and see if that piggybacks the normal audio???
