My mom just bought a new car which is a Toyota camry I believe it is a 2009 version or somewhere along that year. The car salesmen who sold it to her said that in the car is an mp3 hookup however my mom and. I have yet to discover how to use this? Do we need to buy something in order to use the mp3 in the car or does the car have something already that I can just plug my iPod in and it's ready to go? Thank you!
