Hey gents... I wanted to input into this thread as well... As some of you know, I've recently started driving for Uber on occasion in my M3, and as a result, I'm installing a dash cam as soon as I'm home. I'll be installing the Blackvue DR650S-2CH as well. It isn't cheap, but the quality of the equipment and the features appear to be the best. I did a weeks worth of reading on the Dash Cam forum and most agree that the Korean manufactured cams are the best. Heat is the biggest issue, so steering clear of battery cams is wise as already mentioned.
Good luck, looking to see what others install...
