I'm currently using a unit I purchased at Amazon that I read up about on line.
Cost me approx. $115 including the 32 GB Samsung data card.
Look up A1080pgs801. It a unit purchased directly from China from company called E-Prance. What ever, it has a small screen and seems to work fine. Documents constantly and turns on automatically with power, easy to aim with the little screen. It functions as a true dash cam in small file segments that you choose the length of and lock the file automatically via "g's" or manually if you hit a button should something happen. You can have full GPS data also or not. I ordered not for less cost but they sent the full GPS, which you can turn off.
Others on the forum use a "mobius" unit and like it. That unit is slightly smaller but no screen. About the same or a little more cost actually.
Think I'm going to get a second unit for my other work car. Cabling is always the biggest challenge, I've revised mine some now, If I was to do again, I'd add a 12vdc to 5vdc mini-usb (also cheap on amazon) and figure out the power so its not in the cigarette plug. Thats a near future project. Think this will be fun for track days also vs. go-pro. The video is great to my eyes.
