Garmin G900X Pilot's Manual page 303

The G900X SBAS GPS allows for flying LNAV, LNAV/VNAV, and LPV approaches according to the published
chart. LNAV+V is a standard LNAV approach with advisory vertical guidance provided for assistance in
maintaining a constant vertical glidepath similar to an ILS glideslope on approach. This guidance is displayed
on the G900X PFD in the same location as the ILS glideslope using a magenta diamond. In all cases where
LNAV+V is indicated by the system during an approach, LNAV minima are used. The active approach type
is annunciated on the HSI as shown in the following table:
