I've got a Creative Zen, and I'm seeking a new head unit specifically to allow direct connectivity to the player. My backup option is standard auxiliary port, but I'm wondering if there are additional possibilities that would allow greater functionality.

for example, if I used a head unit with a USB port and connected the mp3 player to that, could I use the stereo to navigate the Zen like a SD memory card?

There is also a connector on the ZEn that matches the standard connector on the iPod. Is it feasible that I could connect an iPod cable to this connection and get any additional functionality.



Are there any non-ipod users out there who have tried either of these methods of connecting (or any others, for that matter)?
