USA Spec CB-PA105A iPod® Cable
Crutchfield Customer Review (What's this?)
My old cable had a lose connection at the ipod (which is common with this make after a few years) so that the left speakers would not play unless you jiggled the cable. Well not I get both sides of speakers and solved a second problem of the ipod constantly beeping and having the light go off and then on. The price from Crutchfield is the best I found.
