NAVIGATION SYSTEM (for HDD): Precaution

WARNING: This page is about a different car, the 2008 Lexus LS 600hL. However, it is still accessible from the selected car via links, so may be relevant.

HINT:

After the power switch is turned OFF, the HDD navigation system requires approximately 6 minutes to record various types of memory and settings. As a result, after turning the power switch OFF, wait 6 minutes or more before disconnecting the cable from the negative (-) battery terminal.

  1. NOTICE FOR DISPLAY AND NAVIGATION ASSEMBLY REPLACEMENT 

    Before replacing the display and navigation assembly, perform the SMART Test (see DIAGNOSIS DISPLAY DETAILED DESCRIPTION  ) When the SMART Test result is OK, the HDD memory can be copied. Therefore, copy the HDD memory to the new HDD.
