2010 ford focus radio

mdb98, -Battery: I would disconnect the battery for a minute then reconnect, making sure the terminals are clean and cables are on tight. A weak battery can also cause malfunctions. A place like Auto Zone can check the condition of your battery and alternator for free. -Fuses: Are you sure you checked all fuses? They can be under-hood and in the dash as well. Also, fuses don't have to be blown to be bad, they can be loose or dirty. Check for dirt or moisture in the plastic area, replace if dirty or wet. If the metal prongs are dirty they can be cleaned with a pencil eraser. Make sure all fuses are fully inserted. -Wiring: If things still aren't working, then maybe a wire was knocked loose from a wiring harness. Checking something like that would require opening the dash and/or pulling out the radio and/or screen. Remember to start with the simple solution (battery) and work your way to more complex.
