The Integrated Display shall only be presented in the head-up orientation.

In the GPS settings setting the to 'Heading Up 3d' does not seem to always stick – the GPS randomly reverts to the factory default of 'Heading North Up'.

In navigation mode the radar image shall have the highest display priority and it is only allowed to be presented in the relative motion, head-up mode.

This means that regardless if North Up or Heading Up is selected the aircrafts position will always be relative to the navigational facility.

When Heading Up is selected, even though it may seem that the aircraft rotates around the navigational facility, the aircraft remains in the same position when changing heading.
