But it looks like each switch has the same number of pins where the module gets plugged in. So there must be some momentary break on one of the wires that triggers the audio and video off. Without a wiring diagram, it's beyond my skills. But I bet it would be pretty easy.
Yes, all to save $100, but I like tilting at windmills.

Highly likely it's more complicated that that. All the switches and buttons are communicating over a com bus of some kind, from CAN thought to 100Mb Ethernet, depending upon the component. Yes, the cars have Ethernet.
