I am trading in my 2006 F150 and getting an 2005 excursion due to the additions to the family. I currently have a Avic-Z1 in my truck, and Im hoping it will fit in the excursion....Is the excursion dash similar to other ford dashes? I tried to find a good excursion web forum, but nothing comparable to all the help I have recieved on this site, so figured I would see what you guys know...Also will the factory overhead dvd player still be compatible with my Z1?...Thanks
