You're going to have to eBay it, check with a dismantler (like car-part.com), or go with a factory/oem new replacement.

The iDrive controller snaps into the center console and has a dedicated connector, so you're good there. The rest of the center console should be fine (but note they all share one connection - ie shifter and all buttons).

Removal is easy. Move front seats all the way back. *Disco the batteries!* pull off two side carpeted panels. There are two or three star/hex screws on each side. Once removed, use a soft tool to gently pry up the entire center console, it's one big piece including wood trim. Disconnect two light bars, the center connector, and then the iDrive connector. From there you have a few screws for iDrive and then pop it out.

Wow. I really wish there was an undo button in life. Before I do the eBay route, do you think I can get away with it if I put everything back the way it was and bring it to the dealership to say it's not working?
I think you're better off dealing with the issue and buying a replacement controller. Most likely the car has logged errors from the controller going on and offline or generating errors, and if they look at it and see you've touched it, you're SOL. Gone are the days of "this wire goes here and does this." The vehicle has multiple networks, everything is a module and has logging.

Similar to my situation of not unplugging the battery, you have to pay to play, even when it sucks. Better to fix it and learn the lesson, that's the best route to go.
Thank you. I think I found a good priced unit on eBay. I'll be ordering it and attempt to install it myself.
Good luck!
