JVC KW-R900BT Double Din In-Dash CD/MP3/USB Receiver With Built-in Bluetooth And iPhone Pandora Control
Works pretty flawlessly.  The Bluetooth/phone integration is awesome, I've had no issues making calls.  Getting to play all my music from my iPhone means I can leave all my CDs at home.  The unit seems not to like .WAV files, but it plays MP3s and WMAs.  This stereo is much louder that the stocks stereo in my truck.  My only issue is setting the EQ...I can't seem to get the user EQs to match the presets.
