We got our C-Max last Tuesday and love it so far! Loaded with every option Ford lets you check off, mainly because it was the only one our dealer could get us within 400 miles as nobody wants to trade them or has pending sales due to the insane lease rebate going right now.
Anyway, I have been trying since then to set up MFM. I was so close, got the first activation message, hit accept, and 24 hours later my wife went to take the C-Max and unfortunately hit the Decline button not knowing what it was. Since then, I have restarted the process several times. I canceled the authentication, re-added the car, got the first request, hit accept, waited 48 hours and never got another one.
So I did a system reset on Sync 3, which removed the authentication request from the MFM app automatically, I added the radio ESN, and got the first authentication request immediately, hit Accept, and it has now been about 48 hours again and no second authentication request.
Our 2G coverage in Indy still looks fine, and the fact that I have every time gotten the first request almost instantly makes me thing the radio and service isn't an issue. I am hoping the MFM system on the back end doesn't for some reason get hung up if it ever gets a decline instead of approve, really sucks not being able to use this service to its full abilities.
Any other ideas are greatly appreciated!
