iPod Compatible Car Audio?

I’ve been thinking for a while that I should get a cheap car audio system that includes an aux-in jack so that I could use my iPod to play music in my car (FM transmitters are just too unreliable for city driving and I don’t have a tape deck, only a CD player). Reading this article though makes me wonder if I can just get a car audio system that’s specifically designed for the iPod.

There are a ton of FM transmitters around, a couple of systems that plug into CD changers etc but none that I can find that replace the entire audio unit (since as far as I know mine doesn’t include any pluggable options).

Ideally what I want is a car audio unit that just lets me slide my iPod into a slot when I get in the car and it plays music through my car’s speakers – no cables required.  If it also charged my iPod while it’s there that’d be a bonus.  It appears I’m asking too much at the moment though.

Anyone know of something that does this?
