Adding Navigation if not factory equipped? I purchased a 2011 XLT with MFT for my wife back in April. The vehicle didn't have navigation enabled from the factory, but the salesman said it could be added just by purchasing the card. The parts counter said that someone had attempted this, but it ended up not working. Now, we see that while it is possible to purchase the card, the system must be enabled from the factory to allow navigation to work. I've seen a couple posts where people had their system flashed (I guess a complete reinstall?) Is it possible during this flash to enable the navigation component of MFT?
