I am looking to get a new cd deck, to replace my JVC, and i have seen some that come bluetooth compatible. Now i want a cd deck that is USB ready, because i hear those are the best decks to get for your ipod. I have found that some of the decks are bluetooth compatible, and i don't understand that. Does this have more to do with your cell phone? What does this feature have to do with a cd deck? Also, can you charge your cell phone through your usb port on your deck with a usb cord instead of using the car cigarette lighter?
