I asked this question before but I didn't ask enough questions. But I was going to buy the factory navigation system for my mustang but I was wondering if there is a antenna and if so where does it go? Ive seen a few mustangs with a little black "tear drop" looking thing on the rear deck lid, is this it? Also is the navigation service free or do I have to pay Ford for a subscription or what. Any one with a 2007 up mustang with this option please tell me about it.
Thanks
