Find a module from a 2011-2014 Edge or 2011 to 2016 Explorer as I know they had Sync 2. Your SEL has nav so you need one with NAV otherwise you'll have to patch it with the navpatch to get the license on it. Try a junk yard otherwise your into a few hundred bucks at least. You will need to program it if the replacement has different options than your car. If you can find something from a 2011-2014 Edge SEL you may not need any tweaking at all.
My replacement came from a Lincolnn MKX so I had to reprogram to get rid of the heated/cool seats, steering wheel etc.
If you look on car-part.com its listed under TV Screen or GPS Screen. If you DM me your zipcode I can help you find a replacement.
