Eric you guys with your technologically advanced sporty cars. I plugged my iPod into the battery and all I heard was music by sparks.
Actually Double D Mods (hope I don't break the rules with that) sells an adapter to allow a stock C5 radio to use an iPod and the aux button on the radio. There are actually two versions of it one for in dash CD and the other for the type that Fatboy999 has in the trunk. Slick little unit that ends up with the plug in terminal in the arm rest storage compartment, I may get one. You do have to take a good part of the dash apart to get access but it might be worth it.
