Got the OEM parts on ebay for $235, from Fast Wholesale Parts.
Using this video

The hardest part was separating the controller blank from the module. Take care not to break the channel on the bottom that connects it to the rest of the module.

I got wrapped up in the install and pulled the head unit section from the dash without thinking to protect the giant screen and scratched it.

One dealer quoted $310 for programming. Even with that and the cost of the part the end cost will be half of what that same dealer quoted for the part, install and programming.
 
Be cheaper to get the alfaobd setup and program it yourself, plus have future ability to add/program changes without paying the dealer's bloated fees.
