I just read a number that there are 22 million DVD systems in cars worldwide, and I'm curious to know how many of them are in the US, how many are built-in vs. aftermarket, etc.
So, let's do an informal poll.
1) Do you have an entertainement system in your vehicle?
2) If so, what do you have? Factory or aftermarket? Installed or portable?
3) Do you use it? How often? How important of an option is it overall?
