Summary: I've installed this stereo in my wife's 1998 Camry. The sound quality is great, with a major Bluetooth caveat. Pairing a phone for the first time is easy enough, and goes pretty well. However, with an iPhone 4 or 4S (not tried with any other models), the stereo will NOT auto-pair on power up, which is just MADDENING. You have to go into Bluetooth settings on your iPhone EVERY time, and click on the stereo name to re-connect.
