Thanks everyone for all the info,,,,,,, do I read that right above,the flip down gm screen is $50 ? So the dvd itself is not in the overhead unit on roof,it’s somewhere in the front ? Is that why I see the cost additional for a DVD player in front ? Is there anyone in the Dallas Fort Worth area that has this done that I could meet you somewhere and look at so I know what to expect and have a good idea of how my install is going to go ? Thanks everyone
