Griffin Noise-reducing Audio Cable

Griffin's Noise-reducing Audio Cable features an inline transformer to reduce the interference from a car's electrical system. The 6' male-to-male mini-stero cable works as advertised, and still manages to be less expensive than a Monster Cable. Using it to connect a TomTom car kit for iPhone with the Subaru's aux input jack. The only nit is that Amazon's merchant shipped the gray color instead of black, but it cost only $7.50 at the time so no big.
