■ Update Procedure

1. Check the version before updating in the settings.

3. Add the update data alone to the microSD card (a microSD card formatted with KDR-D21) while files for the Smart Record Display remain on it.
4. Turn on the Smart Record Display.
5. Once it boots up and reaches the home screen (the screen showing front and rear camera footage), insert the microSD card with the added update data.
6. When you insert the microSD card, you will be prompted to confirm the update. Select "Update."
7. Please wait a few minutes for the update to complete.
8. After restarting, you will be asked to confirm the update again. Select "Cancel" and perform a format from the settings.
9. If it then operates normally and the version is confirmed as updated in the settings, the process is complete.

■ Precautions

1. Update operations cannot be performed on MacOS PCs.

2. If the microSD card does not contain KDR-D21 files (i.e., not formatted with KDR-D21), the update will not start.

3. You must decompress the ZIP file and add only the update data within the file to the microSD card. If you add the ZIP file as is to the microSD card, the update will not start.
4. Previous driving data will be erased with the format after the update. Please move any necessary driving data to another storage medium beforehand, or use a different microSD card for the update.
5. After the update, product settings, pairing information, etc., will be initialized. (SD card data will not be deleted.)
