I have a 2008 Ford Expedition EB with the factory installed Sirius satellite and Rear Entertainment system. All systems were working fine. The menu on my radio said DVD Menu (meaning the movie had finished) so I decided to change out the movie for my granddaughter. The disc ejected and I put another in and nothing! It will eject and load and the lights will come on while doing so then again...nothing. There is no FORD screen saver on it at anytime now either. Then I tried to go to my satellite radio and no satellite. I do have functioning AM-FM-CD. When I hit Aux it goes to line-in, Sat1, Sat2, Sat3......no longer shows DVD function at all. I checked the fuses under the dash (passenger side) and also under the hood. All seem to be fine............HELP PLEASE. Did I hit something to lock it all out? Is there a reset/reboot button I can hit. Can't really afford to take it to the Ford dealership for them to fudge with for 4-5 hours. Any suggestions? Thanks...
