It took me 1 hr to figure out how to change the 590X dashcam’s time stamp. The instructions to use the BlackVue Windows app was misleading at best or just outright wrong. Feels like it was coded in the late-90’s. Eventually, after rebooting the firmware, the app allowed me to change the time stamp but it will be 3mins slower because it needs to reboot which is an annoyance. The app will never auto-detect the dashcam over wifi, and you will need to key in username and password EVERY time you want to access camera. Buy at your own risk.
