What does the CDI show me?....
The CDI gives a graphical representation of your boat's course. This 'rolling road' format represents
a width of sea equal to the Cross Track Error (XTE) limits that you have specified in the Setup menu.
As you travel towards the target waypoint, the checkered pattern moves down the screen to
simulate movement at a rate proportional to your boat's speed.
