Not sure that there is any indication that the 21' Mustang will even have Sync 4. Right now it is just the Mach-E and the F150. That said it will most likely be more than the just APIM. The screen will be different as well. But if there is a way to do, I'm sure someone will figure out how. Kind of like Sync 2 to Sync 3. All we can do is wait and see.I'm sure it will be expensive, until we start getting enough wrecks on the market. From what I've seen the software is really nice. Is there a portrait 10 inch option on the 21s? The eye line is already low to begin with.
Ford is lagging the competition in tech, so it could be a good sales boost for them to add options for the remaining S550s.
