I got the concealed display and ran the cord along the top of the windshield and tucked it in with a dull plastic spatula. I used the seam at the corner of the windshield where the top of the airbag cover is and got the cord to the door. I pulled the weatherstripping and ran the wire down the door until I got to the access opening.
I tapped into the cigarette lighter and put my concealed display in the ashtray.
When I get out of the car I just close the ashtray.
