Beware- I bought a 3 foot extension for the Aux audio cable and all it did was blare RPM whine in my ears. Then I bought a plug and play 3 foot extension, thinking that a cable hooked up to the harness would work. Nope, once the engine hit 1500 RPM the whine was there. Not as bad as the extension, but still worthless for listening.
