At the moment I'm using one of those cheap FM transmitters that plugs in the cig lighter to listen to my iPod. It's not very good for many reasons! I have a 2003 Chev Impala and I'd like to leave the factory stereo in, but add a iPod controller of some type so that I can control my iPod without looking down at the little screen. Not only that, but my iPod's LCD screen is messed up and very hard to read, but it's still got the nice big 80gb HDD with my music collection on it. Would be nice to have it wired up and leave it in the glove box or wherever.

From a quick search online I found THIS (http://www.amazon.com/Harman-Interface-Controller-Transmitter-DPFMT1US/dp/B0029XPWE0) which I think it basically I'd be looking for. Does anyone else have one? Any suggestions for make/model or where I could buy one at a store?
