With this and every other model, Ford has done their level best to integrate, (more like metastasize) their abominable radios into every facet of the cabin. This makes them discouraging and sometimes expensive to remove and install an aftermarket unit. When the head unit in mine finally called it quits, I was left with four options.
One was to leave the old unit in place, use my phone and a bluetooth speaker for music. This was probably the most awkward and mean loosing some seat space. Another was to buy a new unit from the Ford dealer at $350 plus installation. Thirdly was having an installer put in something comparable and spending over $500 for the stereo, parts and labor. The fourth option is to do this myself as cheaply and professionally as possible. When I get done, there will be no SYNC or steering wheel controls. The display at the top of the dash will also have to be disabled.
