Firmware Upgrade Guide

​[Why upgrade your dashcam’s firmware?]
Firmware upgrades may add functionalities to your dashcam, and/or improve its performance.

[How to upgrade?]
  • Using an iOS or Android device: download the BlackVue App and upgrade the firmware using Firmware Over The Air Feature (FOTA). Find out more here. 
  • Using a Windows or Mac OS computer: follow the steps below.

[Step-by-step instructions]
1. Access the BlackVue download page (www.blackvue.com.sg/download) from your computer browser.
2. Go to "Download Firmware" section and search for the correct firmware for the BlackVue model that you're using and download to your PC.
    (If you're not sure of the model, you can check out here.)
3. Unzip the downloaded firmware (Zip file).
4. Insert the BlackVue SD card in your computer using the USB reader provided with your dashcam.
5. Format the microSD card using the BlackVue Viewer software. Procedure can be found here. 
6. Copy the BlackVue folder to the SD card.
7. Insert the SD card in your BlackVue dashcam and turn the power on to apply the upgrade.
8. The dashcam will reboot automatically after applying the upgrade, and start recording.
IMPORTANT

​1. Please backup all necessary files before formatting the SD card.
2. The SD card must be formatted in FAT32 format. If you format the card from the BlackVue Viewer, it will be formatted automatically in FAT32.
3. After the firmware upgrade, please use the latest version of the BlackVue Viewer and/or App.
4. After firmware upgrade Wi-Fi login information will be reinitialized. To connect using the BlackVue App, use the default password “blackvue“.
Note: the DR590, DR750S and DR900S Series models have a unique password included in the box and on the camera’s serial no. sticker (you can unmount the front camera to reveal it). These models also reapplies your settings upon upgrade so you do not have to update your password or settings.
5. MicroSD Card support: DR900S, DR750S, DR650S, DR650GW, DR590, DR490, DR490L, DR470, DR450, DR430 Series models support up to 128GB cards.
Note: compatibility is guaranteed only with the official BlackVue microSD cards.
About MicroSD card

​1) Note that we recommend using BlackVue microSD cards for optimal performance.
2) The reason is that dashcams put microSD cards under higher stress than most electronic products such as action cameras or DSLRs due to their constant loop recording. We test our cards extensively before selecting them for inclusion in our products, to make sure that their performance is good and degrades as little as possible over time.
3) Using third party microSD cards can affect dashcams’ performance and in some cases, force the dashcam to reboot randomly during recording. Although the basic requirement of the microSD cards for BlackVue dashcams is Class 10 or U1 and that the SD card should be formatted as FAT32 [Windows] or MS-DOS (FAT) [Mac OS], we cannot guarantee the perfect performance of cards from other manufacturers, as even cards with same specifications may vary from batch to batch.
4) Every BlackVue dashcam comes with an original BlackVue microSD card. In case it is missing or replaced by a third-party microSD card at the time of purchase, please contact the seller to make sure you get a genuine BlackVue microSD card.
Download Firmware
IMPORTANT

​1) The firmware is only compatible with specific model of BlackVue dash cam. 
2) Please ensure you download the correct firmware for your BlackVue dash cam. 
3) If you are just replacing the memory card, you can just insert the formatted memory card (FAT32) to the BlackVue without any firmware. This is exception for DR300/ DR350/ DR300G model.
