To record sonar readings on an SD card using the Humminbird 1158c Combo, follow these steps:

1. Install an SD Memory Card: Ensure that an optional-purchase SD memory card is installed in the slot of the device.

2. Access the Main Menu: Press the MENU key twice to open the Main Menu.

3. Navigate to the Navigation Tab: Use the RIGHT Cursor key to select the Navigation tab.

4. Export Navigation Data: Highlight "Export All Nav Data" and press the RIGHT Cursor key. A confirmation dialog box will appear.

5. Confirm Export: Press the RIGHT Cursor key again to confirm the export. If you want to cancel the export, press the LEFT Cursor key.

Note: If no SD memory card is installed, an error message will be displayed. Insert the SD memory card and try again.
