I have 2009 FX4 with sync but not nav. Does anyone know whether there is an aftermarket rearview that has the carmera screen along with the microphone buitl in it? My truck has the revear view mirror with the mic built in for the sync and was wondering if industry has come up with duplicate of it with a camera screen yet? I would love to have a back up camera but I don't want another screen/gadget stinking to the windshield. Does anyone know of anything out there?
