BlackVue Troubleshooting Guide

Are you experiencing problems with your BlackVue dash cam? There’s often a very simple fix for most problems. Have a look at our handy troubleshooting guide below for solutions to some of the most common issues.

If you’re still experiencing problems after referring to the guide, simply bring your dash cam back into a store where one of our expert colleagues will be more than happy to look at it and hopefully resolve the issue.

SD Cards

My BlackVue camera is giving "check SD Card'voice alerts.

  1. Check that the SD card is correctly inserted into the dash cam.
  2. Reformat the SD card. The simplest way to do this is to load the BlackVue Viewer application for PC or Mac, then click the SD card icon and select "format". The formatting process will begin and take a matter of seconds. We recommend formatting the SD card every couple of months to maintain the best possible performance.
  3. Make sure that you're using a BlackVue SD card. BlackVue doesn't recommend the use of any third-party SD cards with their products. If you are using a non-compatible SD card (i.e. one that wasn't designed for use in high-performance dash cam), you'll likely experience problems. 

Dash cams are really tough on SD cards, constantly writing and rewriting large chunks of video to the card for long periods of time and, in doing so, inflicting damage on the card's memory cells. BlackVue high-performance SD cards are specifically designed for use in BlackVue dash cams. They include wear levelling control technology and bespoke error correction code to minimise cell damage and guarantee long life, even under prolonged and heavy use. 


My camera is not powering up.

  • Check that the power cable is fully inserted into the 12V socket in your car.
  • Check that the fuse (contained in the cap at the end of the power cord) hasn’t blown.

If you’re powering your BlackVue using the Power Magic Pro or Conecta OBD Parking Mode accessory, and your car hasn’t been driven in over 24 hours, allow the engine to run for several minutes so that the battery can reach its peak voltage. The camera will then power up normally.

If you’re powering your BlackVue from a battery pack such as the B-124X Ultra Battery, check that the battery power LED is illuminated and that the battery is charging.



My smartphone can’t find the BlackVue when I look for it on Wi-Fi.

Press the Wi-Fi button on the right-hand side of the BlackVue. The camera will audibly confirm ‘Wi-Fi on’.

My BlackVue camera won’t connect to Wi-Fi.

Double-check that the correct password is being entered. The password for your BlackVue can be found by removing the camera from its windscreen mount and looking for the silver label on the body of the camera.

Check that your smartphone is connected to the ‘BlackVue’ network. On certain Android phones, Flight Mode may have to be enabled to allow the BlackVue camera and app to communicate with each other.
