My stero in my car has a USB slot in front so you can who Ipod/Iphone up and play it on the system. I was able to even play my older ScanDisk MP3 player on it as well. So I hooked up my Captivate and never would work. I turn on the player like I have seen my daughter do on her Iphone still, it does not regonize the player. I guess it is all in the USB setting? I have tryed all and still no luck, will this thing not output to stero? I noticed through Kies it will let me play music on my captivate through my PC. Thanks, David H.
