Messages and Unit Settings
The GPS 150XL' s M key provides access to system messages and allows you to
customize the unit to your own preferences through a settings submenu. Whenever the
GPS 150XL needs to alert you to a navigation or system message, the annunciator light
(U) next to the M key will flash. Some messages are advisory in nature (e.g., the arrival
and countdown alarms), while others may require your immediate attention (e.g., poor
GPS coverage). For a complete list of GPS 150XL messages, please see Appendix D.
To view a message, press M. Press M again to return to the previous page.
The GPS 150XL' s settings submenu is also accessed from the M key.
