	Page 63: Orientation	The map page is a visual representation of your current position in relation to the other waypoints stored in the receiver. If the receiver does not have a base map (eTrex, eTrex Summit, eTrex Cammo), the only objects that appear on the screen are your current position and any waypoints you have previously stored in memory. If the receiver has built-in base maps (eTrex Legend, eTrex Vista, eTrex Venture), the map page shows your current position, all previously marked waypoints in a addition to your location on the map. A receiver that supports maps is like having a paper map in your had that automatically tells you where you. GPS Made Easy explains the several ways to orient the map page regardless of whether the unit has a base map or not.
Map Screen	Page 64: Track, rings, scale	GPS Made Easy also explains how track lines can be used to mark the path of your travels, how rings can help measure distance between objects and how to keep the screen uncluttered when the scale is really small.
	Page 48: Goto Function	The Goto function allows the user to select a destination and the receiver guides the user from their current location to the destination. It is the most important capability of a receiver. GPS Made Easy describes the importance of the Goto function. The use of the Goto capability is shown through out the book. All of the steering screens, navigation statistics and example trips in the chapters use the Goto function. Goto is also the foundation of routes.

The sequence of screens below shown how the Map Screen looks when the user selects a destination to 'Goto'.

	Map Screen The Map Screen shows the user is headed to some destination that is not shown on the screen. The direction is shown along with the scale of the map at the bottom. There is no base map. GPS Made Easy: Page 63 - 64: Map Screen		Review Waypoint Screen From the waypoint screen, select the waypoint you want as a destination. Select the Goto function as shown. The receiver will now guide you to the waypoint 'HOME' from your current position. Goto is a very powerful feature. GPS Made Easy: Page 48: Goto Function. Page 62 - 63: Steering Screens. Chapters 5 - 11: Use of the Goto function in navigation.

	Map Screen The screen shows the direction from the users current location to the destination 'HOME'. The Map Screen is oriented so that the destination is at the top of the screen. GPS Made Easy: Page 63 - 64: Map Screen		Pointer Page The pointer page has been discussed in the its own section, but here it shows that the user is 17.5 miles from 'HOME' and it will take 53 minutes, 17 seconds to get there at the current speed. The user is heading at a bearing of 248 degrees. Note that the arrow is straight up, which means the user is going in the right direction to get to the destination. GPS Made Easy: Page 51: Bearing (Azimuth). Page 57: Direction Indicators. Page 62: Steering Screens.

	Pointer Page Now the user is only 16.7 miles from the destination 'HOME' and will get there in 51 minutes and 18 seconds. The user should travel at a heading of 250 degrees to be headed directly towards the destination. The two degree difference between the heading and the bearing means that user is not headed directly towards the destination. As the user gets closer to the destination, the difference between the heading and bearing will increase and the arrow will no longer point up. At that point, the user will know that a course correction needs to be made in order to get 'HOME'. GPS Made Easy: Page 51: Bearing (Azimuth). Page 57: Direction Indicators.
