Unhappy Programming help

Due to a water leak in the rear driver's side quarter (thanks sunroof) I lost all MMI operation. I replaced the SATELLITE RADIO RECEIVER / TUNER 4G00350828 unit with a used one and everything is working fine except for certain radio functions - one of which is volume control so I got nothing. I am told it needs to be programmed. My Audi guy and my local dealer won't touch it. Any ideas? Is there anything I could do myself? Anyone near MD/DC/VA on east coast USA that can help?

MY12, tuner unit in the left rear, so we're to assume this is an MMI 3G vehicle. 4G0 035 082 x (x being whatever revision letter), so the US spec radio unit with integrated sat tuner. But if you do not have B&O, then this is also the amplifier.

There's no excuse for a dealership not just doing the replace function on the replacement unit to program it for your VIN and clear the component protection. If your dealership is a tool, then find an Audi familiar indy shop to do it. Half hour labor, done.

One of the programming bits is whether you have an outboard B&O amp or not. If it came from a vehicle that did and you don't, then it's coded wrong and you won't get any audio since the internal amp is disabled at the moment. But even coded correctly, you won't get entertainment audio without the component protection (CP) reset. And that requires ODIS with a live subscription to the Audi overlords.
