An error occurred while formatting.
When you keep encountering an SD card error when you are at the start or in the middle of downloading a file/app from Navigation Updater, you can take the following measures.

If the SD card error occurs as follows, please check your SD card or card reader first:
  • Symptom: Fail to format a removable storage device, “An error occurred while formatting”
  • Cause/Measures to take
  1. The error happens when an SD is not available for reading or writing.
    First, check the location of a Lock switch on the left side of the SD card. If the switch is in the right place, check if it is formatted on a PC.


    If your SD card is damaged, you have to replace the SD card with a new one.
    In some cases, it might be a problem with an SD card reader or SD card slot embedded in a PC.
    Thus, it would be better to try with another SD card reader (or other USB port) if you have one before replacing the SD card in question.

  2. If the SD card is damaged, you have to replace it with a new SD card.

※ Reference: When you remove an SD card from the PC, you should select a safe eject method for prolonged use of the SD card.
