You can use the phone for everything , or use your IPod for music, and leave your phone out for calls only. It's your choice. Both will hook up through the Y cable that plugs inside the armrest. Both will also charge when plugged in. Sometimes I use my IPhone for everything, and other times I use the phone. It's your choice. Hope that helps.
