By default, this receiver shows the map with north always at the top of 

the screen (North Up). This is the way most maps and charts are 

printed on paper. You, however, can change the map orientation to 

Track Up, Course Up or Heading Up, if you switch to Advanced Mode. 
 

   

 

The default North Up setting is fine if you are always traveling north. 

What you see to your left corresponds to the left side of the map and 

what you see to your right is shown on the right side of the map as long 

as you keep heading north. But if you travel any other direction, the 

map will not line up with your view of the world. 
If you want the map to match up with your view of the world when 

traveling in other directions, use Track-up mode, which rotates the 

map as you turn. That way, what you see on the left side of the screen 

will always be to your left and what you see on the right side of the 

screen will always be on your right. 
Another option is course-up mode, which keeps the map at the same 

orientation as the initial bearing to the waypoint. With the fourth op-

tion, heading up, the map rotates to keep your heading at the top of the 

screen. When track-up, course-up or heading-up mode is on, an "N" 

shows on the map screen to help you see which direction is north. 
Depending on the circumstances, you can benefit from switching back 

and forth between North Up and Track Up settings. If you are in an 

area you know fairly well, run the unit in North Up. But when you are 

in unfamiliar territory and want to instantly coordinate your surround-

ings with what is displayed on the screen, switch to Track Up. Try all 

three modes to find what works best for you.
