Panasonic CQ-RX400U

The Panasonic CQ-RX400U is an in-dash receiver that supports AAC, MP3, WMA, and CD-R/RW playback.  The receiver features a bright white-on-black LED display with a dimmer and detachable faceplate for security.

  It has a built-in MOSFET amplifier that provides a total of 72 watts of RMS power handling as well as MOSFET output stage for accurate sound reproduction.  The CQ-RX400U includes an AM/FM tuner, CD changer control, as well as both AUX and USB inputs on the front panel allowing the user to play audio directly from their iPod or MP3 player.  It is also compatible with an optional expansion module which allows connection to a satellite radio receiver or Bluetooth handsfree kit.  The receiver comes with a wireless remote control and a 1 year limited warranty.  The CQ-RX400U is an upgrade to the CQ-RX200U since it includes AAC compatibility, a front-panel USB input, and MOSFET output stage which the CQ-RX200U lacks.
