    PROCEDURES NECESSARY WHEN BATTERY TERMINAL IS DISCONNECTED/RECONNECTED

    Note

    After the engine switch is turned off, the navigation system requires approximately a minute to record various types of memory and settings. As a result, after turning the engine switch off, wait a minute or more before disconnecting the cable from the negative (-) battery terminal.
