Can someone please help me. This is probably a very stupid question, but I honestly do not know. How does the MP3 player work? I've been told by the folks at Best Buy, there are two types of MP3 players in a car. One is a CD that accepts MP3 format and will burn approximately 120 songs. The second, you plug in an MP3 player such as an iPod. Which does the Sky use? I would really appreciate anyone who can answer this for me. Thank you!
