I have a Blackvue DR300G (probably a newer version is now available) which I have used for a number of years and moved over to my Mini when I got it last year.
It is mounted to the screen beside the mirror using an adhesive pad and is unobtrusive and has worked flawlessly. Easily removed with the push of one release button.
It is powered from the 12v socket and the cable is easily led round the windscreen behind the trim up to where the camera is.
A very useful piece of kit, should it be necessary for insurance or legal reasons.
