    Note


    • Navigation System

      After the ignition switch is turned off, the navigation receiver assembly records various types of memory and settings. As a result, after turning the ignition switch off, make sure to wait at least 60 seconds before disconnecting the cable from the negative (-) battery terminal.

    • Audio and Visual System (w/ DVD Player)

      After the ignition switch is turned off, the radio and display receiver assembly records various types of memory and settings. As a result, after turning the ignition switch off, make sure to wait at least 90 seconds before disconnecting the cable from the negative (-) battery terminal.

    • Audio and Visual System (w/o DVD Player)

      After the ignition switch is turned off, the radio and display receiver assembly records various types of memory and settings. As a result, after turning the ignition switch off, make sure to wait at least 80*1 or 90*2 seconds before disconnecting the cable from the negative (-) battery terminal.
