You might want to check just so you know what your limit (of minutes or hours is).

Also, few weeks ago wife tells me, "I finally agree with you about having DashCam. I was driving and this person almost hit me....".
So naturally I go and grab the memory card.
SHIT! the memory card is corrupted and needs formatting. Last event recorded was December 17th.
So much for evidence.
Come to think, I should check to make sure it's recording OK now.

Is it a micro SD card? If so, did you try a different micro SD to normal SD card? It shall be a simple contact to wire to contact on a larger scale. But sh** happens.

KOT

I had the opposite I parked my van in front of my house on Friday afternoon. Monday morning go out to my van and there is a huge dent. I don't move the van go grab a cup of coffee call the cops. Cop get there show him the dent and a dent in my neighbors car that matches my dent perfectly. Cop agrees that was the cars dent matches up perfectly. Nothing happens because I didn see it happen.

They can't do anything just denie it.

I can not just deny it. I am the first to tell someone to f off. It has been sent to collections where the problem lies. Our agent inspected vehicle yesterday. No damage found.

Challenge it with credit bureau. It's a fairly simple process.
