Garmin eTrex 20 User manual
Getting started with an eTrex 20 29/12/2015
When you first switch on your eTrex you’ll get the Main menu screen appearing after a short time.
From here you can move around the screen using the thumbstick (also called the joystick or toggle)
Toggling - moving the thumbstic up or down or left or right - will highlight a different submenu . Initially
the one in the top left-hand corner is highlighted – in this case Ma
Clicking – pressing the thumbstic down gently – will bring up the submenu.
Pressing the menu button will bring up a list of options for the menu visible on the screen.
The zoom in/out buttons are only used to alter the image size when a map is shown
Since it is often easiest to navigate around by first returning to the main menu it is important to now that:

if at any stage you are in a submenu and wish to return to the Main menu just
press the menu button twice [occasionally you may need to press the back button
first]
The main menu has 25 submenus of which only 6 can be seen on the
screen at any one time.
These submenus “wrap around” so that from Ma to Adventures you
can toogle down 12 times or, more simply, up once
Many of these submenus are not of immediate interest to a hill wal er
and can be removed from the main menu – they can be restored very
quic ly should they become of interest.
Example:
If the main menu is reduced to the 9 submenus above
and arranged as shown then, whenever you return to
the main menu, Ma is highlighted and the three most
commonly used submenus can be selected very quic ly.
