8/11/2004

I added an update to both texts.  When creating a route using the map display on the Legend C, Vista C, 60C, and 76C there is an extra little trick.  If you press ENTER at a point where there is no map information you will be prompted to create a new waypoint.  You will then come to a new waypoint screen.  To get back to the route that you are creating, press the QUIT key instead of selecting any of the buttons at the bottom of the page.
