Garmin gxm 31 manual

Do not apply cleaner to the electrical contacts on the front of the unit. Storage - Do not store the GXM 30 where exposure to temperature extremes may occur, as permanent damage may result. This can be on the outside of the vehicle or behind the windscreen of the vehicle. Place the GXM 30 where is has a clear view of the sky and turn on the Garmin unit. This automatically turns on the GXM When the Garmin unit is turned on or when a new feature is selected, the GXM 30 has to receive new data before it can be shown.

You may experience a delay before weather data or a new feature appears on the map. Page Satellite Mosaic Satellite Mosaic Satellite Mosaic displays infared composite images of cloud cover taken by geostationary weather satellites. The Satellite Mosaic provides up to seven levels of cloud cover.

Page Lightning Lightning strikes are represented by lightning bolt icons, as shown in the images below. Lightning appears on the map if strikes were detected within the last seven minutes. The ground-based lightning detection network only detects cloud-to-ground lightning.

Lightning bolts indicate a cloud-to-ground lightning strike. Page Storm Cells Aviation units show the direction of the storm with an arrow. The tip of the arrow indicates where the storm should be in 15 minutes. Critical information about the storm cell can be viewed by selecting the storm cell with the map pointer. Page Hurricanes indicated by a red line. The darkened squares that appear along the red line display the projected locations received from the National Hurricane Center.

Page Winds Aloft Aviation units display winds aloft using wind barbs or a wind streamline depending on the zoom range of the map. Similar to Marine and Automotive units, the wind barbs indicate wind speed and direction. The wind streamline indicates wind direction with arrows. Page Surface Pressure Strong pressure gradients are associated with areas of stronger winds. Page Fronts Moving away from a High Pressure Center in any horizontal direction results in decreased pressure.

Page Visibility In the example below, visibility ranges from 1 miles to 4. Displaying multiple features may help to provide a clearer picture of the weather conditions in the area. Page County Warnings To view information about the warning, select the county with the map pointer.

The temperature breaks are indicated by isotherm between successive waves. The wave wave is moving, as indicated by the direction of the red arrow. Page Marine Warnings When a Marine Warning is issued, the area for the warning is highlighted in red.

To view information about the warning, select the warning area with the map pointer. Page Buoy Reports Report readings are taken from buoys and coastal observation stations. Sustained surface winds of 30 knots or more at the surface. Freezing levels. Page Sigmet 3, square miles. Page Tfr Red active or Yellow not yet active.

Echo Tops can be helpful in determining the severity of thunderstorms. The and are used to control what you listen to but cannot reproduce music to listen to via the Garmin chartplotter. Here's video that shows the relationship between the Garmin , GXM 31 Smart Antenna, and your installed stereo radio.

A radio receiver captures and amplifies radio signals, then it demodulates them into baseband signals like audio. It is a good thing we have Tom here to explain their product line for them. One other question: Is the reason the XM option does not appear under the config. Perhaps the receiver is really in the Garmin s and the presence of the GXM 31 just unlocks that little secret.

During the XM activation process the smart antenna id number is validated by XM's equipment.
