Features Specifications

Versatile front USB 1-wire input2

Convenient front panel design

The easy-to-read single line LCD display shows source information, clock, station ID and track data when playing back digital files from the external USB devices. Front auxiliary input lets you connect almost any portable audio device to your car's sound system.

Powerful in-dash amplification

The redesigned, internal Dynamic Reality Amp circuitry boasts 47% lower internal resistance compared to conventional receivers, delivering 55 watts x 4 to your interior speakers. This allows you to crank up the volume while maintaining low distortion, low noise levels and smooth frequency response. Your music isn’t just louder, its clearer too.

Customize the sound using the built-in EQ3, 3-band, graphic equalizer. Adjust the mix at 60 Hz, 1000 Hz and 10,000 Hz in 1 dB steps from -10 dB to +10 dB for a dynamic sound experience.

Intuitive music search features

Use Quick-BrowZer® to find music by artist, album, genre, song or playlist. Jump Mode allows you to fast forward through a category in 10% increments to help you find a specific song.

Passenger Control for iPod®3

Let your passengers play DJ and control your iPod®3 directly from the device while it’s still connected to the receiver. Simply hold the MODE button during playback to enter and exit Passenger Control playback mode.
