Need some help with broken MMI

[million__52]

My MMI from my Audi A5 2013 is completely unresponsive. We have tried to press power button but nothing appeared on the screen. The garage switched MMI of other car to try if the screen is working and it worked. We assume that the problem is solely from MMI itself. Another problem is broken purple port at the back from UPS shipment. So i come up with 2 questions in mind

 

1. Where can i find a used MMI ? (Part No.: 8 R2 035 670 C)
2. Is it possible to fix it?

Best place is eBay in my opinion. I buy most things on eBay.
