My friend has an 07 infiniti g35 sedan with the GPS/DVD system and it will play dvd's but only when the vehicle is in park.
Some car owners believe that a car DVD player is a pure waste for them and it is also illegal to drive a car while watching the DVD player. However, things are different if they drive a car with other passengers. They can easily get their passengers entertained if they have a car DVD player. Also they can let their car DVD player carry the GPS Navigation system which is indispensable for modern society.
