Help with factory ford HU
I am replacing a friends factory head unit in a 2006 Ford Fusion with another factory HU. Does anyone know if I can plug and play newer year HUs? I'm trying to add an aux port. Also will steering wheel controls still work? I have heard that new HUs will have to be programmed. I can work on my truck with my aftermarket HU all day, but a replacing a HU with another factory one has me stumped.
