Did not work for my needs
Crutchfield Customer Review (What's this?)
These cables were recommended by Crutchfield as a replacement for an iPhone 4 connector on my older Alpine iDA-X305, which i also purchased from Crutchfield originally. They do not work as connectors and produce a "USB Device Error". I am sure they work fine for other things, but not for my car audio connection. I'm bummed, as I'd love to use my perfectly functional car stereo, but can't find a replacement cable.
