In the title box, the fix type is displayed at the right end. Here, you will see
either 3D or 2D characters. The 2D mode is a two-dimensional position fix
mode that will not factor the calculated altitude (antenna height) into the L/L
position solution. AUTO mode calculates altitude. Generally, the 2D mode
works the best for marine navigation.
The Status display also includes readouts of your estimated position, local
date and time, and antenna height.
There are two softkeys on the GPS Status screen. Thmsoftkey accesses
the GPS sensor Initialization sequence. Thm softkey permits special setups
