2016 HUD Navigation Info missing???

[PGLex]

Hi All, Quick bit of advise please.     2016 car with HUD.     HUD is working fine, but fo some reason the navigation directions have stopped popping up on the HUD even though it is switched on??   I have searched owners manuals etc and played with all settings, but cannot seem to get the navigation to function correctly on the HUD anymore?    Any suggestions?

 

Thanks. Paul

I believe there is a way to disable/enable the nav guidance. Try press and holding the DISP button

Thanks Colin.   There is a setting for Driver assistance and i have the Nav function on, but the navigation directions no longer appear on the HUD?     Speed, Lane assist, Compass, Tachometer etc all work fine.  Just the nav instructions have gone. They used to appear just before junctions, and then fade out again.?
