re: Are dash cams worthwhile?

I got a Garmin Mini, installs behind the rear view mirror and I bought the dongle that it powers from the rear view mirror, so no cords to route.

Only close calls so far. The Garmin networks to your phone, and footage is downloaded easily directly to your phone, with no wires.

Buddy at work has used his 3 times successfully to get out of "no fault" wrecks or a pile up where he was in the middle and they weren't sure who hit first.

It has saved him thousands of $.
