V1 auto mute circuit......anyone??

The audio adapter gets its data from the audio wire; it does not use the CD data wire.

It gets the mute info from the CD data wire doesn't it? It needs to know whether to route the signal through the mute volume ring or not.

Too bad there isn't a sheet like the one you posted earlier for the audio line!

So if my understanding is correct, and the remote audio gets the mute information from the data line, simply interrupting that wire (data wire) between the V1 and Remote audio unit, changing the "Loud" bit to 1 (for "Soft") after a set amount of time, and sending that to the audio unit on the data wire should do the trick....

You don't need a sheet since the audio line doesn't carry data, it carries the actual audio signals. Connect it to an amplifier and speaker and you can hear the alerts. The complexity of a remote audio adapter is in handling muting.
