I am going to be buying a new head unit soon and I have a question. The receiver has an Ipod and usb input. Will my epic play music and Pandora through the receiver? If so, what is needed? Will I use the USB cable or buy an Ipod type aux. cable to plug into the headphone jack? I have plugged my epic into another car with an Ipod cable and it plays Pandora however with the volume up I can barely hear anything through the car speakers. Please help. Thanks.
