I just bought a 2012 Edge and am wanting to upgrade from a 4in to 8in. Is this an easy swap and what all do I need? Can I use one from an MKX and where is the best and cheapest place to get one. If I just changed the bezel to the 8in one and put in the 8in touch screen would it plug into my existing unit or do I need to replace the radio unit also?
