Adding an iPod to your vehicle is really easy and there are many options to do it.
You can either add on an iPod controller or a P.I.E. interface to your vehicle. An iPod controller adds an external LCD screen and joystick controller that allows you full control over your iPod while your iPod remains hidden and it also charges the iPod. The P.I.E. interface connects to the CD changer or satellite port and plays the music through your car speakers but doesn't control or display the songs.
