Hi, my 2014 F150 has one of the small 3 inch (I think it’s that size). It has a backup cam and controls the radio options. The screen has gone white and I can’t use the above items. The speakers also are on the fritz and I believe they are all connected some how. I want to try to fix this issue myself without having to take to the dealership.
I have checked all of the connectors to the screen and speakers- all good. I have removed the battery terminals and let the computer reset and nothing has helped. Please any guidance would be appreciated. I am a new user so sorry if I posted in the wrong page.
