When I ordered the desion Gateway light (not Amazon), for me was not evident that a further cable is needed to connect the iPhone, which has very annoyed. . Bin with this product but very satisfied but, even if the cable still at least 30 cm longer could have been; Gateway is me behind the radio and this Dock Cable is passed from there in the center console, on shifter, handbrake in the armrest and there connected to the phone. Since it is a bit too short in my opinion, I have an iphone extension cord or ordered. It is important that of course, the audio signal is transmitted !!!
