Magellan Meridian FAQ – Version 2.0

27) What are all of these secret menus?
Magellan built a bunch of secret menus into the GPS. These are supposedly for testing and to try out new
functionality.
There are two ways to access the hidden menus:
§ If your Meridian is turned off, hold down GOTO and NAV and tap the PWR button. In a couple of
seconds you should see a box pop up with "00" inside of it. At this point, release GOTO and NAV. Use
the direction pad to change the "00" to the number of the menu that you want, and then press ENTER.
§ If your Meridian is already powered on, press the MENU button. Then press and release LEFT, RIGHT,
LEFT, RIGHT, and LEFT again. The secret menu box will pop up.
In some cases your Meridian may become "stuck" and need the "three finger salute." Hold down GOTO, ESC, and
ENTER. This will immediately shut the Meridian down.
NOTE: Do NOT use any of these secret menus unless told to do so elsewhere in this document. Some of these
may erase the memory of your unit or do other nasty things, which will cause your unit to not work. They
are included simply to make this FAQ a complete reference. PLEASE, PLEASE, PLEASE do NOT use the
following table unless you know exactly what you are doing.
Thanks to ClayJar, luis_scsc, Daniel de Wildt & Ed Maurer for information in the following table.
