I want to install a dvd headunit in my 1998 Jeep Grand Cherokee but with the lip above the opening I don't know if its possible. Will some of you guys who are installers chime in and tell me if you have done this and if there were any modifications involved. I have seen people on cardomain who have them installed int he dash but the screen doest go completely up due to the lip. If thats the only possible way I will just change my mind and find a new headunit. Thanks In Advance.
