The following GPS functionality is currently supported by the 900 Series™ Chartplotter when it is connected to the included GPS receiver:

View current position

View current track (breadcrumb trail)

View precision speed and heading from your GPS receiver

Save tracks, waypoints and routes

Travel a route and navigate from one waypoint to the next.

Your 900 Series™ supports Navionics® Gold, HotMaps™ and HotMaps™ Premium on MMC or SD card media.

NOTE: Your 900 Series™ does not support Navionics® Classic Charts, only Navionics® Gold, HotMaps™, and HotMaps™ Premium.

Your unit also comes with a built-in UniMap™ with a more detailed map of North America (Domestic models) or a more detailed map of Europe and Southeast Asia, including Australia and New Zealand (International models).

Your 900 Series™ uses the GPS Receiver to determine the position of the boat automatically, and uses the zoom level settings on a particular view to select the best chart to display. See Viewing Cartography for more information.

Multi-Media Card

(MMC)/SD Slot

Your 900 Series™ Chartplotter also has a multi-media card (MMC)/SD slot that is used to insert optional-purchase cards containing additional detailed maps. If you insert an MMC/SD that contains a more detailed chart for a particular location, your 900 Series™ Chartplotter will retrieve that chart and display it automatically. Use the

illustration to locate the position of the MMC/SD slot cover, remove the MMC/SD slot cover, then insert the MMC/SD into the slot. The label on the MMC/SD should face toward the left side of the unit. Press down on the card until it clicks into place and replace the slot cover. Then, replace and tighten snugly - do NOT overtighten, as this will not improve water resistance, and may damage the cover.

Software Updates

Use the MMC/SD slot to update the software version of your control head. To update the software in your control head, plug in the appropriate MMC/SD card that contains a software update file; the unit will recognize it, will tell you what software version your control head is currently running, and will ask you if you want to update the software in the unit to match that on the MMC/SD card. You can obtain software updates from the www.humminbird.com website.
