JVC KWAVX640 Double DIN DVD / CD / USB Receiver with Proximity Sensor and 6.1 Inch Widescreen Touch Panel
This unit has several great features and is relative priced, compared to others on the market.  The only issues that I have w/ this unit is the response time when using the a Ipod is slow.  Also, sometime it's hard to make selection on the touch screen.  You got to press one button and actually select something completely different.  This is my first double-din receiver, so this may be common.
