Warning
These commands are not documented by Magellan for a reason - you can "break" your unit using them, requiring a service repair to recover. These repairs may not be covered by warranty, so proceed at your own risk.
If the unit is powered off, the following commands may be helpful:
- IN + PWR - Full selftest of unit including screen test, keypad test, NMEA test.
- OUT + PWR - Serial port test
- ESC + PWR - Burn-in process
- LIGHT + ENTER + PWR - Upload of new firmware
- NAV + PWR - Service Function window
- NAV + MENU + PWR - Force power off
- GOTO + OUT + POWER - clear memory and set all settings as default.
While unit is powered off, press and hold the NAV key then press the PWR key. If the unit is already on, press MENU key then press right-left-right-left arrows. In the center of the screen, the service function window with text "00" will appear. Using the arrows, change "00" to the number of any service function listed below, then press ENTER.
