BlackVue DR750-2CH,
I love this camera, yup, connects to my phone, small in form and a rear looking camera (2 CH) Its HD which is very important, if you get a hit and run, you will need to zoom in and read the plate that is why HD is very important!
This unit has wifi direct to your phone so you can actually view the videos live or scroll over past videos and watch them.
The unit has GPS so there is no question of where and when.
Another feature I like is the parking mode, it records while parked, I travel and stay in hotels so when I get in the truck in the morning it will alert me that there was an impact etc. The video will also be highlighted so I do not have to watch video after video trying to figure out which one has had the alert
I have a HD BlauPunkt in my Marauder, its just basic, works great but you have to remove the SD card to view the vids.
