Hard to say what was damaged if anything....
But one thing you can try..Is to disconnect the battery for about 10 minutes then reconnect.
It is pretty easy to do..you have to remove the ECM that is mounted on top of the Battery..The ECM cover just clips on and slides to your right and then there is one Phillips head screw holding the ECM in position...then you'll need a 10MM socket to loosen the battery cable...NEG cable is all you need to remove.
But while you're waiting, look at all the fuses related to the Nav Screen/radio
