When you use the Soundgate interface to play your non-Ipod MP3 back through the stereo, what sort of controls do you have? Do you need to load a play list from the player first? If so, then can you go track to track using the controls on the stereo? Is there more functionality there? I soo dont want to buy an Ipod since I have another nice player, but would hate having to do all navigation through the player itself. But I'm having trouble knowing how the device could control the player at all via the headphone jack. Maybe I answered my own question, or maybe there is a USB type connector/adapter that can do this. Otherwise its off to the store for an Ipod, and the factory interface. BTW its an '06 S2k with the standard stereo.

Thanks for any input.
