Aux input ?????
I have recently purchased a used 2005 Jeep Grand Cherokee Laredo. It is equipped with almost every option available. It has a factory installed stereo w/ a single cd player. No navigation or satelite radio, just regular. My question is it has a plug area about the size used for headphones and it says Aux above it. What exactly is this used for and are there other uses for this? Can I use it to play an MP3 player, DVD player, and do I need some special cord or plug to use this? I know it sounds like crazy questions, but this is all new to me. Thanks for any help!!
