That looks like a good one, but is it safe to have a DVD player in your dashboard? Not trying to be a buzzkill, but... I am
Most if not all indash DVD players have a mechanism that only allows them to play video (other than navigation) when the parking brake is on. It can be bypassed, but it's a DIY job that might earn you a ticket if you're caught using it while driving.
Don't believe everything on the Interwebz! A duck's quack DOES echo!
