Is it included with every MCS Hot Chili? I had a spec sheet given to me before buying my car and it says it is included but my car doesn't have it. I already asked my dealer and obviously they have no idea what it is and if it is included or not. I even showed them a picture of it sitting in the glovebox but still they give me absurd answers. I don't think I need it but if I pay for it, I want it!has anyone configured the 6-disk DVD changer? if so how does it work. Does the f56 play DVDs or is it just formatted that way so we can use DVDs to store more audio files compared to a regular CD?
