Actually 1 of 3 submittals.

Pretty safe to assume that there’s no way to go from 3.4 to 4.x with 3.4 compatible HW, right ?

Sync 4 APIM may work in Syn3 cars but there won’t be a UPDATE to make Sync3 be Sync4

Not Optimistic. The hardware is completely different, including the interface to the vehicle.

Again, not optimistic. It will take some work to do it and I think it can be done, but is it worth it to hack up the car for this…time will tell.

I reckon it will work, the only interesting thing of note is the module makes use of ethernet for communication with other modules rather than solely relying on hscan. I have seen that sync 4 will be fitted to the Focus mk4 which is only hscan, so it should in theory work OK on modern fords.

Pretty confident that C1MCA (focus mk3, kuga/escape etc) will NOT work though.


Does C1MCA include a Transit Connect?

Yep it does: Ford Global C-car Platform - Wikipedia

Thanks @louage. Does anyone know what these ports are? When Mitchell from Town & Country TV opened the glove box, he found this. He said it was a pre production vehicle, so something will look out of the ordinary. It might be ports to access different modules and update their firmware?

Interesting, obviously a breakout box for something. There is a gateway module breakout box for current vehicles available so could be an alternative to this:


Yep. Seen this arrangement quite a bit when I was doing camera safety systems, like the HUD’s and stuff, for military vehicles years ago. Usually there is an extender box that ties into the vehicle networks. This allows the engineers to readily connect to the vehicle without having to compete for ports.
