a friend just bought a 380 and was wondering if anyone had tried to put in a roof mounted dvd screen into the vehicle ?

seeing it has no middle interior light is there still a mount in the middle of the roof ?

The 380 DOES have a mid-roof interior light. I'd try sticking some screens on the back of the front seat head rests.

The vehicle definitely has a middle interior light, as well as the two map readers at the front.
