The official viewer is the primary tool for managing these files. It allows you to view front and rear camera footage simultaneously and export them as standard video files.
If you’ve pulled the SD card from your or GNET dash cam and found a bunch of files with the .jdr extension, you’ve likely realized they won't play in standard apps like VLC or Windows Media Player.
Insert your SD card into your computer and open the PC Viewer . It should automatically detect the JDR files.
