    Note


    • After the power switch is turned off, the radio and display receiver assembly records various types of memory and settings. As a result, after turning the power switch off, make sure to wait at least 120 seconds before disconnecting the cable from the negative (-) auxiliary battery terminal (for Audio and Visual System).

    • After the power switch is turned off, the radio and display receiver assembly records various types of memory and settings. As a result, after turning the power switch off, make sure to wait at least 120 seconds before disconnecting the cable from the negative (-) auxiliary battery terminal (for Navigation System (for Radio and Display Type)).
