The data comes from the same source. Why Ford disables the Message Center's display of the info, if you have the NAV radio, is up for just speculation. However, both still have access to the data.
There is no "jumper" that enables/disables the Message Center's display of the info. So, yes, it must be in the vehicle's unique configuration file, loaded on the assembly line. I have never found anyone, with access to those or knowledge on how to set/reset features within them.
