NOTICE:

  • 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 85 seconds before disconnecting the cable from the negative (-) battery terminal. (for Audio and Visual System (for Gasoline Model))
  • After the engine switch is turned off, the radio and display receiver assembly records various types of memory and settings. As a result, after turning the engine switch off, make sure to wait at least 85 seconds before disconnecting the cable from the negative (-) battery terminal. (for Navigation System)
