Want to beef up your mobile audio system without dropping a lot of cash? The KD-G420 CD player from JVC has you covered. This versatile stereo plays all your discs, even those loaded with MP3 and WMA files. Its powerful amplifier combines with a premium digital-to-analog converter for outstanding reproduction of all your discs.

Two sets of preamp outputs make it easy to add an external amp or sub to your system. And you can customize the sound using cEQ's six preset tone curves — each of which can be tweaked individually. A loudness control ensures rich, full sound.

Need more entertainment options? The KD-G420 will control an optional JVC satellite radio, or you can use the front-panel auxiliary input to connect a portable MP3 player or DVD player. If you have an iPod, use JVC's optional iPod controller to manage all of your playback functions right from the KD-G420.

Features

MP3/WMA Playback: The KD-G420 can play MP3/WMA files that have been recorded on CD-R and CD-RW discs. The disc must be recorded in one of the following formats: ISO 9660 Level 1/Level 2, Joliet or Romeo. You can directly access folders numbered 01-12 (they must be assigned two-digit numbers when recorded). Each disc can have a maximum of 8 folder hierarchies, 200 folders, and no more than a total of 512 files and/or folders on each disc.

Satellite Radio Ready: You can connect a satellite radio tuner to the KD-G420 in a couple of ways. The unit is directly compatible with the SIRIUS SIR-JVC1 Satellite Tuner for JVC (item # 607SIRJVC1). The Terk XMDirect universal XM Satellite Radio tuner (209XMD1000) can be connected to and controlled by the head unit when used with the XMDirect Smart Adapter for JVC (209XMDJVC1).

Note: In addition to the optional satellite tuner, you will also need the proper antenna and a subscription to SIRIUS or XM Satellite Radio.

Custom Equalizer (cEQ): In addition to manual bass and treble settings (-6dB to +6dB @ 100Hz and 10kHz), this unit also has six selectable preset tone control and loudness setting combinations. Each of the sound modes may be adjusted to your preference and stored in memory. The preset Custom Equalizer modes are:

  • Rock: Bass = +3, Treble = +1, Loudness = On
  • Classic: Bass = +1, Treble = -2, Loudness = Off
  • Pops: Bass = +4, Treble = +1, Loudness = Off
  • Hip Hop: Bass = +2, Treble = 0, Loudness = On
  • Jazz: Bass = +2, Treble = +3, Loudness = Off
  • User: Bass = 0, Treble = 0, Loudness = Off

Amplifier Gain Control: When you are using the KD-G420 with factory speakers (or those rated to less than 50 watts peak), the Amplifier Gain Control can limit the amount of power being sent to those speakers. When the Amp Gain Control is set to "low," the volume control ranges from 0 (minimum) to 30 (maximum). When using speakers rated higher than 50 watts peak, you can set the Amp Gain Control to "high," and the volume control will range from 0 to 50.

Preferred Setting Mode: By activating the Preferred Setting Mode (PSM), you can set the clock, choose the time zone, select the dimmer mode, select the external component type (changer or line input), turn on/off ID3 Tag display, switch between US standard and European tuning spacing, and set the Amplifier Gain control (high/low).

Source Naming: The KD-G420 allows you to assign names of up to 8 characters for AM and FM stations (30 station maximum). You can also assign names of up to 32 characters for CDs (including a connected CD changer, but not MP3/WMA or CD Text discs--30 disc maximum). 

Direct Track Access: You can directly access CD tracks 1-12 by pressing the station preset buttons. If a preset button is pressed for less than 1 second, the track corresponding to the number on the preset button is selected (for tracks 1-6). When a preset button is pressed for more than 1 second, the track corresponding to the number above the preset button is accessed (for tracks 7-12).

Front Panel Auxiliary Input: A front panel stereo minijack is provided to allow the connection of a portable audio source. Just connect your portable cassette, MD or MP3 player to this unit, and you can listen to the audio from the portable player through the speakers in your mobile audio system. The input level of the auxiliary input can be adjusted from 0 to 5.

Clock Display: While playing a CD, you can switch between the clock display and the CD elapsed time display (the track number always appears). While listening to the radio you can switch between the clock display and the station frequency display. When you press the Display button during power off, the unit will turn on, display the clock for 5 seconds, then shut off. This can be done with the ignition on or off.

Dimmer: This unit is equipped with a wire that JVC calls an illumination lead, however, it acts as a dimmer lead. The dimmer can be set to Off (normal brightness at all times), Auto (display window automatically dims when your car head lights are turned on), or On (display is always dimmed). Note that the amount of dimming is fixed, it cannot be adjusted, and the illumination wire must be connected for Auto operation.

Optional Interface Adapter for iPod: The optional KS-PD100 adapter allows an iPod digital music player with a dock connector to be hooked up to and controlled by the KD-G420. You'll be able to scroll through all your playlists, albums, artists, genres, and composers directly from the head unit. Song titles and other file information show up right on the head unit display. The iPod is also charged while it is connected to the KD-G420.

Optional Wireless Remote Control: The KD-G420 can be controlled by the following optional wireless remotes: RM-RK50 or RM-RK60.

Changer Controls

Compatibility: This unit is equipped with JVC's "J-Link" CD changer control system. It is fully compatible with JVC's CD/MP3 changer (257CHX1500). Other JVC CH-X series CD changers (except CH-X99 and CH-X100) can be controlled directly by this head unit, however, they are not compatible with MP3 discs. You cannot use the KD-MK series CD changers with this unit, even with an adapter.

Compatibility with Optional Input Adapter: An optional JVC Line Input Adapter (item # 105KSU57) or Aux Input Adapter (item # 105KSU58) may be used to provide an additional auxiliary input on this unit. This feature allows you to connect a portable audio player, such as a portable MP3 player, to this unit as an additional audio source. The adapter connects to the CD changer input on this unit. When the adapter is connected to this unit, a CD changer cannot be connected.
