It's missing one optocoupler, but will be done by Fri hopefully.
The pic shows the coiled cord that will plug into the armrest. The left circuit is the new board that has the following on it:
Performs the mute function
Can adjust to balance mic input from the Audi
resettable fuse to protect the board and car. IF it trips, it will reset in about a minute, without having to be replaced.
Uses an optocoupler to completely isolate the grounding feature from the handsfree, for further protection.
Will fit in a project box that will go in the trunk - no need to route any wires, or remove any panels/trim. It simply plugs into the DB25 that's in the trunk area.

Here's a closer shot of the circuit board

I hope you where just joking ;) You know that you do not have to drille the glass for the external
antena. I sticks on via the double sided tape and so does the reciever on the inside of the glass. The signal is sent through the glass from the antena to the reciever.

Nice looking board Ed...if you wanna test that w/o having the opto-coupler you can...
Just stick an LED into the Opto-Position...the Cathode of the LED should face the Collector of the transistor...the Anode end of the LED should connect to the Current Limiting Resistor...
Plug it in and observe if the LED lights when you have a call and goes out when the call is dropped. I don't remember what value I picked for the current limiting resistor...but if it's low enough this should work.
