i was gonna say if you need just aux, theres a tutorial on the interwebs that tells you how to make it out of computer wire.. took me all of 10 minutes to do, and i didnt have to spend any money.. i was looking at the rb10 though
i needed the cd-rb10, but you dont have to solder the wires like everyone says... if you have computer wires(ones inside of computer with black connectors) you can take the wires out of the black connectors and they fit perfectly on the pins
