Hello we just pruchased a used 2008 4.7l aspen....Just wondering what is the best way to get dvd in there....It has a after market Kenwood Nav system for a stereo...has the output for dvd....but i Also have a VES system out of a 07 mega cab wondering what it would take to install? Does the aspen with dvd have a different headliner or do i just need the mounting bracket and cut the headliner?

Thanks
