29. Now it's time for the head unit. The DEH-P5800MP features 50 watts of clean MOSFET power, deep-blue OEL display with screensavers, and background videos. Playback includes MP3, WMA, and normal CD format, plus it's ready for Satellite Radio (XM or Sirius)-we chose Sirius. Because this unit will play MP3 format discs, we can have one CD with about a 150 songs on it. The unit also has BMX (Bit Media eXpander) Digital Enhancement to take that compressed music and adjust it to sound much fuller. All in all, this is a very nice head unit.
