Ok, I ran into the same problem with my 03 EB. Didnt come with the OEM DVD , but I went out and got the orig OEM DVD player. I was told by the dealer that if it didnt come with it originally, then forget it. Because u need the DVD controls on the factory radio to control it, not to mention the harness.So if ur head unit doesnt have the DVD controls then forget it, u cant install an OEM DVD player. So I decided to go with an aftermarket DVD all-in-one system. 1- U can get a bigger screen than the OEM DVD player and 2- easier to install. Hope this helps ! ! ! !!
