Garmin GPSMAP 130 - Manual (Page 22)

A B
Now that we’re navigating to an actual destination, let’s move on to the next
page of the GPSMAP 130 system, the navigation page:
1. Press the J key.
The navigation page provides graphic steering guidance to your destination.
The bearing (BRG) and distance (DIS) to the destination, with your current
course (COG) and speed over ground (SOG), are displayed at the top of the
page, along with a graphic compass to indicate your cardinal heading. The
esti-
mated time enroute (ETE) and velocity made good (VMG, or the rate you are
closing in on your destination) are displayed at the bottom of the page.
As you head toward the destination, the middle section of the page gives you
visual guidance to your waypoint on a graphic highway, which displays the
route and nearby waypoints on screen. The moving arrow below the highway
always points to the destination waypoint relative to the direction you’re moving.
The line down the center of the highway represents your desired track, while the
bottom of the page provides a graphic indication of your crosstrack error (the
distance and direction you are off course) according to the scale at the bottom
right of the page.
