i dont know if you got my message or not, yea, this will play your iphone, just not charge it. i know this because i have two ipods, an older nano and a 3rd gen touch, nano plays and charges, touch just plays. The adapter is the CeNET EA1251...can be used for a cd changer, bluetooth, ipod, etc. yes, very easy install, no harness needed, just an antenna adapter
