my audio and my navigation stop working.when i press button climate and back up kamera it work.when i press the map.they show blank.i bring to dealer and they said it because of my remoted starter and they have to take out whole dash to see whats going on with my navigation.my car still under warranty but dealer always claim it because after martket remote starter.they tell me it cost 650$ for 5 hours to take out the dash.i can take out my navigation but i dont know what to look for.anyone know are there any fuse related to audio or navigation?i check all fuse from passenger side and driver side under hook.which no help.i also disconnect battery but no luck.are there any fuse box behind the glove box?

 

There aren't any fuse box behind the glove box that I know of. There is one in the engine compartment, but that's more for outside engine stuff. If the screen and climate it's working it's probably not a fuse. Is the radio and other things work? (if those work too, then it's definitely not the fuse) You can try updating the nav software ...

 

the radio did not work.everything work except the radio and when i press the map and the menu button .they show blank.is there any way to eject map disc without go to menu button?
