The GPS tab provides a visual reference of satellite acquisition,
receiver status, and accuracy. The sky view and signal strength bars
give an indication of what satellites are visible to the receiver and
whether they are being tracked. For more information about GPS,

Weather Tab
Use the Weather tab on the Main Menu to view individual weather
features without turning all other weather features on or off. For

the Map window that appears on the Weather tab. When you close
the Main Menu and return to the Map Page, all of your previously
selected weather features still appear on the Map Page.
