I am very interested in knowing how you went about this. I have a friend who's got a Dodge truck with radio buttons built into the steering wheel, and we also envisioned controlling the Empeg via its serial plug in the same way you did.

My friend doesn't have an Empeg yet (he intends to buy a Mark 2 when they become available), but he wants the steering-wheel-button functionality when he does.

He works at a high-tech company that manufactures RS-232 and -485 controlled audio routers, so he has access to any necessary parts/expertise.

What can you tell me about the project?
