just bought an auvio audio cable wtih car charger

How exactly does it work with an android phone to play your music. I have both a cd and cassette play. how does it work when you plug it into the car charger to play music you have on your phone.
What does Audiogon "The High End Audio Community" have to do with playing music on your phone? Maybe you should try the Radio Shack where you bought your Auvio cable.
