This is fantastic news! I have a 2016 MKX with the old 3G modem that is being put out of service. According to the Ford documentation, the C-Max and MKX share a common 4G upgrade kit - AMMU7J A00A25 AA.
I haven't called around to see if a dealership will sell me just the retrofit kit, but it's not showing up in any of the online Ford parts dealerships. The instructions reference IDS, so I was worried about the dealership having to activate the kit.
I've started working my way through the 80 page F-150 forum thread, lots of into there.
If I wanted to try to retrofit a module from another Ford vehicle, is there a specific reason you went for the Escape unit, or could any 2018+ unit work for me?
Do you think there's some kind of initial setup the dealership would have to do on a brand new modem that you didn't have to do on an already-activated used one?
