Replaced the monitor display, entire unit?

Hi, I replaced the monitor display, entire unit, on my car listed above. Now, some functions work, others don't. The controls for a/c, heat, radio work. However, there's no GPS/maps, no back up camera, etc. I've read that when these are replaced, they need to be "reprogrammed" for the sync 2 system to work.

Is this true? If so, is there a DIY way of doing it without taking it to the dealer, and spending an arm and leg? Of not, any idea price?

Also, I now have some dash lights on that weren't before. Airbag. Traction. Hill assist. Could these be related to the monitor, or perhaps I have an issue with the dash connectors? Thanks!
