I have a alpine dvd player. Question is does anybody know the little trick to play a dvd while the vehicle is in gear. On mine you have to push and the hold the break on then push the parking brake on, off, and then leave on and the dvd will play. I can put the parking brake on just on click but when I start moving, the parking brake light flashes and gives that awful dinging noise. I know there is a way to do it but haven't had time yet and just thought I would get some quick info. Thanks.
