This is a great idea in theory. Unfortunately it doesn't completely work as stated. Everything works fine except for one flaw that makes it an annoyance. There's no problem when I connect my iPOD through the connector and the user interface is pretty straight forward. The problem lies in the quality of the sound that comes out. I haven't tried using the FM transmitter so I cannot comment on that aspect. I do have an auxiliary jack in my car which produces crystal like sound when directly connected to my iPOD. Now when I connect the auxiliary cord from the car to the module that relays all the information from your iPOD it produces a static sound that is very noticeable and progressively gets worse as the iPOD remains connected. I contacted Harman Kardon to see if there was anything they could do and I have yet to hear back from them. Therefore I cannot recommend this product to anyone. Poor customer service and a shabby product to boot.
