I have a 2010 GL550 with the 30 pin iPod connector in the glovebox. It recognizes some of the older 30 pin iPods (Nano & iPhone 4) but will not recognize a 30 pin iPod Classic (6th gen / 160GB). The message is "no device connected." Any idea why? Is there anything I can do to get this large capacity music library to connect with the car? Any and all help MUCH appreciated!
