A convenient 3.5 mm stereo input jack is also available for any audio device with a headphone jack or other type of AUX output.

FL Display - The bright 1-line display makes it easy to see the text information when navigating the menu, your iPod or music content.   
 Variable Color Illumination – This allows the user to match the Kenwood unit’s illumination with the vehicle dashboard lights from the wide pallet of available colors.

Single Pre-out with Low-Pass Filter - A low-pass filter allows the outgoing signal to a connected amplifier to filter out midrange and high frequencies. This is useful for amplifiers powering subwoofers as it keeps damaging mid and high frequencies from being amplified and passed through to a speaker designed to handle only low frequencies.

 Remote Control - This wireless remote control easily control volume levels, switch music sources or select your favorite tracks with the numeric access keys.
