you should buy the avic-z1 from etronics.com (where i got my Pioneer AVIC-D1 in my SI and my Pioneer AVH-P6400CD which i had in my old civic). They offer it for $1700 (about wholesale) with 1 year warranty from Pioneer. It has a built in DVD player that plays DVD-R/RW and MP3's and sh*t and the navi is read off the 30 GB hard drive.
Here's a link to the page.
