Hi, I'm picking up the AVIC-Z1 in a couple of weeks. I've been reading everything about hacking the hd which was the first thing I wanted to do so I can swap it for a much bigger one to be able to store more music in it, but from what I read so far it's not lookng too promising, and I hear the Ipod interface is sluggish. I was wondering will the Z1 read MP3s burned on a DVD? especially a dual layered DVD.

No it can not. You can make audio DVD's but not a DVD of MP3's.

Dang it! thank you for the quick response though.
