OK I just got a Panasonic CD/MP3/WMA player to replace the stock radio in my gen 1 HCH. The new MP3 player is disk based but has a cool option to hook up to an iPod with an adapter. I understand that this adapter charges the iPod and also displays iPod info on the radio and even allows the radio to control the iPod. This all sounds very cool and I'd like to set my car up with a such a system.

Now the tricky part:

I don't have an iPod but I do have a 8GB Creative ZEN MP3 player. Can I use the ZEN instead of an iPod? If so please link to the seller of such an adapter....

Part 2:

I've heard that iPods are restricted in what you can put on (or perhaps take off of)them. With an iPod can you rip your own CDs to MP3 and put them on the iPod or do they only take iTunes? Can an iPod play wma or ogg files?
