I updated my Sync 3 navigation system from version 3.4 19101 to version 3.4 26057, but a problem occurs as soon as I turn on the car’s ignition: the display brightness drops and becomes almost unreadable—as if it were dimming. Does anyone know a fix? I would be very grateful for any help. Thanks.

Drop your build to 3.4.23188, it doesn’t require reformat.

3.4.26057 isnt really a general release, right now Ford has it as a dealer only install.
