I recently replaced (by myself w/ help from a friend) a Phase Linear deck to a Sony MEX-BT2700. The thing is that I am getting sound to the tuner but none from the CD player or BT device. I have the Motorola Droid and the deck used to be in my truck so I know the device is compatible w/ the deck. The deck is connected to a 5-channel amp. I am completely stumped at the problem. Please help if possible. Thanks.
