Nicely made cable.
Crutchfield Customer Review (What's this?)
It is a nicely made cable, however you do need to remember to plug the USB connector into the USB on the back of the CarShow UN1170 unit otherwise the HU will not see the iPod. Tested it with a couple of 6th gen Nano's running 1.2 and a 4th gen Touch running 6.1 with no issues.
Pros: Nicely made.
Cons: No instructions.
