Prospective Focus owner. Is it feasible to remove MFT and the Sony control panel and replace it with a DIN (or double) aftermarket head? Many sources (Metra, Crutchfield, etc.) seem to rule this out without a detailed explanation. I'm fine with losing every MFT feature I'm aware of. I would just use the physical climate controls, adapt the steering wheel controls and reverse camera to the new head, etc. Am I missing something? Thanks.
