Well on the radio side, you mentioned you checked all the fuses.
Assuming you just didnt pull out and looked at the fuses and used a test light or some sort to check if you actually got power flowing to those fuses with the key ON.
Next is to check if you have power going into the radio.
The multi screen display gets its power from the radio.
No power to the radio = no screen display.
Also check grounds as well.
Without ground, the radio will not work either.
Temp gauge and/or AC might be on a different circuit but im not 100% sure.

2 fuses you need to check for the Nav screen.
10 amp dome
7.5 amp Radio no.2
If those 2 fuses are good, your mechanic needs to check if there is power flowing to the nav unit.
He needs a wiring diagram to pin point which power wire it is to the nav connector.
This would be my next step if it was me.

To clarify, when you say the mechanic changed the screen out, do you mean he changed out the actual LCD screen or the whole assembly unit?

Default Radio and ac. Door locks not working!

checked all fuses and are ok. Went to dealer and found out it was a ground wire that was the problem. Said it was water on it . $500 repair and all is ok. In case anyone has the same problem
