I own a Garmin Dash Cam, and one of the features is red light and speed cameras alerts, however this feature is hidden behind a subscription, the camera doesn’t require internet connection all the time, so theoretically the files could be reverse engineered. I tried to do a quick google search but got nothing, does anybody know if this feature has been cracked?

That means your footage would have invalid date/time stamps, making it useless when you need it for its intended purpose.
