Here is what I found for my Sony. Judging by the lack of responses I got I'm guessing that there are not too many Sony car stereo/iPod owners out there.

Anyways, if you are one...

I purchased the Sony XA-300 through a friend who works at a stereo store. Got it for $75.00, listed at Crutchfield for $99.00. It's a 5"x7"x1" box with all sorts of RCA ins and outs, headphone jack (with volume) and USB. Find an appropriate spot for install and hook up connections. Works great.

Plus or minus (depending on your thinking). No extra screw holes or tabs to make mount permanent. You get some velcro to attach. Sony recommends under the passenger seat. I slid it under the cup holders in my Caravan. A permanent hookup would be nice to deter thieves, but then again if they really want it they are going to get it. So I may just pull it out and pop it in at will. We'll see. Actually with cup holders extended the unit is pretty obscured.

If anybody has any ideas how to make a better hookup let me know.
