When I was a teenager the coolest tech you could have in your car was a CD player—and these things skipped half the time.

Back to a couple of years ago, the coolest tech you could have in your car was a CD player.
Nowadays, of course, things are different.
Many cars come with Android car radio that you can connect your smartphone.
These android head unit allow you not only to play your music from your smartphone,
but also install other application for news, maps, media, movies, and even games.

For those cars which were made decades ago, things like native Bluetooth is not optional.
Fortunately, almost all of the car has the one-din or double-din standard for the head unit.
The car-parts companies could provide the universal Android head unit for the cars according to the standard, make sure that the owners could install the unit in the cars.
So those who running the old cars could buy the suitable Android touchscreen units, and install in their cars by themselves(you can find the tutorial on the Internet).It could be very cool that you integrate the modern type of driving into your old-style car.
