If you are purely looking to play music, then their auxiliary input adapter ($60) will work work fine. But I have to admit that having a hands free call function is very convenient. The work involved with installing any device is pretty much the same. I have the whole shabang including the bluetooth adapter which ended up costing around $200. If you buy from IPD, then it is a little cheaper. If I had to do it again, then I would have just bought the Bluetooth Hands Free Car Adapter Kit which is about $135. I never use the wired connection in my car and the charging is done through the cigarette lighter usb plug.
