Use this intelligent adapter to connect your iPhone 5 or 5s, iPod touch (5th generation), or iPod nano (7th generation) featuring the Lightning connector to many of your 30-pin accessories. The 0.2m-long cable provides extra length to connect to 30-pin accessories.
It's as described. I have a dock connection cable for my car stereo. The adapter keeps all the functionality I had before (charge, transfer audio out from ipod or pandora). Some have complained that the lightning connection on this adapter is larger than the standard issue usb cable that comes with new iphone/ipod. This is true. I have a speck candyshell style case and have NO issues with the larger connection, but I can see where this could cause a problem with some cases. The cable itself is only about 8 inches long. So if you're thinking this cable adapter is going to substitute as an extension as well you will most likely be disappointed. The description under specs says that the cable doesn't support ipod out. I'm not sure exactly what this means. As stated before my music app on my phone functions as normal with this adapter. So I'm thinking ipod out function must be specific to ipods. The price could be more reasonable, but I had enough rewardzone points saved up to cover the purchase so it didn't sting quite as bad.
