Humminbird 898 SI Cartography

I installed a new 898 SI unit on the front of my boat and a 788 DI unit at the console. My 788 DI is working like a dream ,But the 898 SI unit does not give me the option for a chart view. It is seeing the GPS puck and the 788 unit. Any help would be appreciated on how to get to the chart view.

Under the "Views" tab in the Main Menu System should be several different options of chart views....

Each chart view setting will either be set to "Visable" or "Hidden"...

Are any of these chart view selections showing up under the "Views" tab...??
