Well that's certainly quite strange but I know for sure that having my D7 beacon over to my D700 and changing the position results in the nP display and/or the full display (depending on my settings for how to display data).  Both of my radios are much newer with the D7 being less than five years old and the D700 is less than three.  I transmit the same status message at all times, too, so it's detecting the change in the position in my case.
