I have the thinkware u1000 duo although I kind of wish I went with the blackvue. Over all it's not bad, it's just big and bulky. Also there doesn't seem to be a way to disable the audio recording. And the lights on it are kind of annoying. I basically have to set my phone as a wifi hot spot to connect to it
It was very easy to run the cables for it using the head liner, really didn't take much time at all. I did not have to take off the a pillar panel
To mount the rear camera I cut out a small piece of sheet metal, made a small hole in it and it's being held up by those light grey head liner pin things, but if you want to make it really easy just go buy like a small sign that they would use on a restroom door and cut that up.
