I'll do some piccies in the morning as the light is going now. Regards mounting on the dash in the middle - you can to an extent - you'd still have to use the suction cup, but have the camera upside down and then in the settings tell it that (so it took pictures the right way up), however IMO, not a good place to have a dash cam, as you cut too much off at the bottom. The ideal place is up by the interior mirror. And actually that's not too bad, as there is a gap between the headlining and the windscreen, so the cable "tucks" away behind it (I've taken mine down the passenger side); on the "A" pillar, you can gently prise out the covering over the screws to get the cover off and get the cable behind there (actually mind pushed behind no worries so I found out later), you then get a short piece of about 6" showing as it goes across from the bottom corner of the "A" pillar (where it meets the dash) to the door, where again, it pushes back behind the side of the dash, and then underneath, you can just pull the carpet back to get it behind the panelling, behind the glove box and up to the ciggie lighter vicinity. So all in all, realistically, I only have the bit of cable between the windscreen and the door, and a bit of cable where it plugs into the ciggie lighter showing.
As I say I'll do a series of pictures in the morning and post them up, did try but they were coming out too dark to make anything out (trouble when you have a black cable on black headlining and dash!
The thing you can't get away from though (sorry) is the suction cup on the window. But it does hide behind the mirror!
