The solutions when the rearview of the dash cam does not display are: 1. Remove the wiring and check if the rear camera wiring is damaged or aged; 2. Replace the dash cam or camera; 3. Check if the plug is loose; 4. Check if there is an issue with the memory card. Reasons why the rearview of the dash cam does not display: 1. Loose plug, as the dash cam vibrates and shakes during vehicle movement, it may cause the plug to loosen; 2. The camera wiring is damaged or aged; 3. There is an issue with the camera or dash cam itself; 4. The memory card is too full.
When the rearview of the dash cam doesn't display, I first check if the rear camera connection is loose, as this is the most common issue. Take out the dash cam main unit and gently tug the cable to see if there's poor contact. Also, check if the power supply is functioning properly, such as issues with the cigarette lighter socket or fuse. If all these are normal, try restarting the device—turn off the dash cam and power it back on, waiting a few minutes. If it still doesn't work, access the settings menu to toggle the rearview mode, as accidental touches might disable it. A dirty lens can also cause a black screen, so wiping it with a soft cloth may help. Finally, it's advisable to regularly check for cable aging to avoid sudden failures that could affect reversing safety. These simple steps can often resolve the issue without the need to rush to a shop and spend money.
