If you have a mac, the option may appear if you were to right-click on the file. If you are unable to extract the firmware files, then look to wards using a file unarchiver program.

4. Transfer the new files to the Dash cam:

Put the card back into the camera, start your car, and plug the camera back in. If the firmware files were copied properly, the LEDs on the underside of the camera should light up and the red/green lights should flash. If the firmware update is completed successfully, the camera should start recording which is indicated by the solid red light.

Do note that It can take more than 5-10 minutes so please be patient.


5. You can verify that the upgrade was completed by looking at the smartphone app under "Information" or using the Blacksys Desktop Viewer program. 

*Note: If the firmware update fails, format the card again and repeat the steps.
