Forward looking rear view camera

I use a COBRA dash cam in mine it works really well, the colors are right on, it catches about 180 degrees of the forward view. It has sound or you can turn the sound off. The resolution on the Cobra is very good. I had two cheaper models before the Cobra and was not happy with them at all. I use a 32 GB san disc in mine for long recordings, however it will automatically re-write if you want it to. It will also take stop action shots w/the press of a button and hold them even though you may decide to re-write or format. It will hold those stop action shots in the event of an accident or some such.
