@bozack, I get it. I thought I would just use the nav on my phone, but I have found myself in areas without cell service where the vehicle nav system came in handy. It will also help with the trade-in/resale value of the vehicle. There are pros and cons for each option.
That should not be a problem. I did just that when I ordered my Mach 1. I initially ordered without the Nav, then asked if I could add it. They added it without any issues. If you ordered a 22, it really should not be a problem since HP cars will build in early spring.
I ordered a 22 Mach 1 700A HP through my dealer, after my 21 got canceled. The order is confirmed and I have the DORA. I was told that Ford will begin building the HPs in March or April.
