Navigational (global Positioning System) Gps problems of the 2011 Ford Edge

While conducting an at-home sync2 software update to version 3. 10 via a properly formatted usb flash drive, the component that failed was the accessory protocol interface module (apim) resulting in the vehicle's entire infotainment software, the back-up camera, gps, bluetooth, radio, climate controls, essentially all functions through the center touch screen to completely stop functioning. Roughly half way through the sync2 update which consisted of having the vehicle in an engine-on idle-state as required by Ford, the center touch screen displaying the update progress bar faded to black and ambient lights were lost. Ford claims that this at-home update could take anywhere from 45-60 minutes. I allotted 90 minutes for the update to complete its processes thinking the screen going black was normal during this update. After realizing the screen didn't come back on after a long while, I knew a bigger problem existed. The vehicle has been inspected by technicians at a local Ford dealership and their conclusion was to spend $1,888 plus labor and taxes to replace the apim. I do not agree with Ford and their conclusion on this incident given that I had shared the reason as to how this occurred in the first place. No warning was given or error code provided during the day of the incident. I followed Ford's directions for an at-home update and now as a result, my vehicle is not fully functional and Ford is making me pay for it.

Ford sync system has been freezing, back up camera blacking out, gps stalling. Car has been returned to dealer 3 times for a reboot system. Dealer said it has to do with the new system and there being bugs.
