I came across this on Crutchfield.com and it's also available at bestbuy.com which is the only place I shop for electronics, but anyways...

Basically this unit is FM modulated and comes with a remote control, but the cool thing about it is that if your stereo has RDS then the artist, album and other data can be displayed on the factory stereo display.

This unit has 2 AUX inputs (for MP3 players and such), 1 USB input and also has inputs for Sirius and HD radio tuners. All for only $199!

I don't know about you guys, but this is the way I'm going with my system. This way I don't have to give up the six disc changer, and most importantly the Bluetooth integration!
