Why replace your factory radio?

Two good reasons - sound quality and cool features. A new car stereo offers power that's superior to most factory radios, along with more sophisticated tone controls. And most car stereos offer built-in or optional features that add safety and fun to life in your car, including inputs for your iPod or MP3 player, Bluetooth connectivity for hands-free cell phone calls, satellite radio or HD Radio reception, and connections for building an audio system in your car.

Lasting Value

Written by: mmmmna from New England, USA on July 25, 2009

I have owned the KD-G820 for 2 years, I am transferring it to my next car. I do not own any iPod, and I never tried using the Sansa into the USB port but I will try.

Pros: Yes, it definitely DOES read cheap USB flash drives, I use a 4 Gig and have used lower capacity Cruzrs. Flexible equalizer and decent preset tone settings. Display color reaches a respectable white level, uses individual R-G-B color controls to set the display color.

Cons: Only ONE color at a time on the display (lots of hues available, but only one at a time), the subwoofer output is not very user configurable; not easy to transfer the deck to a new car since the required installation sleeves were being closed out fall 2008 and you are expected to bend the sleeve tabs when you use the one sleeve it ships with. Limited depth of 'folder' access on USB devices. Very limited font options (2), none of which are noted for extreme readability. Display could be larger (height); the "eye candy" (the graphic displays) are very limited but considering the era, this is not unexpected; 4 Gb USB devices are the maximum.

Note: I discovered by accident that my KD-G820 deck seems to have VERY limited support for Ogg Vorbis encoded files.

All in all, a very good 'early' product for its genre and its price.

Asking for 64 Gb Flash support, OLED displays and DVD+/-RW support for the next generation.



Packed with features and aggrivation.

Written by: Bin_jammin from Connecticut on September 28, 2007

I'd like to think I'm up to snuff on electronics, but this thing is ridiculous. It has every feature I could hope for, but I need to drive around with the manual in the glovebox. This is the first stereo in this price bracket I've owned in quite some time, and I COULD be happier. Also purchased KS-PS100 Ipod adapter, and let me say, searching through my ipod is terrible.

In order to safely find a song while driving I'd have to pull over to search, because of the time it takes to scroll through my library. Also it would be nice to have the song info, artist info, and album info all on the screen at once, but JVC decided it's more important to keep the input source on the display at all times. Menu layout is terrible, the scroll wheel could be much better implemented than as a volume knob.

This is basic interface stuff JVC. I know children that could figure this stuff out, why can't you?

Audio quality is great, no qualms with that, but it takes so LOOOOONG to get there with adjustment... this is in a project car, you have a USB interface, why can't I save my preferences to a USB stick? I lose everything every time the battery is disconnected.

I think I'll sell this unit and find something that makes me smile every time I use it, rather than make me want to rip the steering wheel from the car and smash it through my head unit.

Crutchfield Customer Review (What's this?)

After reading all the reviews... I went with this one for the USB support and got a lot more. The USB technology is in its infancy, some mp3 players work and some dont. Some flash drives work (CF Reader with 1gb card) and some dont (cheap usb thumb drives). But what most people fail to mention is the awesome equalizer included in this deck. You can control frequency range in the high, mids, and lows as well as the Q! Most people dont even know what the Q represents in a parametric equalizer...great system!

long story short, this is very difficult to use. didn't like the eq setup, you can't just adjust bass & treble offhand. you have to go into menus and set personal eq's. alot of the icons on the screen were rather small and hard to see. would not recommend for the first time user. would be uneasy recommending to the experienced user as well. usb port and sound quality were great, i will say that.

2003 Saturn ION 3
Crutchfield Customer Review (What's this?)

I put this into a Saturn ION that had the factory amp and component speakers. The audio quality is a step up from the factory radio, which was already pretty good.

Used the iPod adapter and routed the cable so my iPod can sit in the glove box. Wow! Better than expected.

One downside is that you can't control how much the display dims at night. The default is fine for city driving, but out in the country where there are less road lights, it gets distracting. Of course, it is a really nice display to be distracted by!

It is lame that you can only load images and animations from a CD and not the USB port.

FM reception is better than the stock radio.

The iPod interface works great, but it shows you the album name followed by the artist and usually the screen only has room for the album. Weak.

Overall, the controls for the audio and radio are fine, but loading images or changing the colors on the screen takes way too long and it is easy to screw up and have to start over.

Crutchfield Customer Review (What's this?)

This is a great unit! My wife wanted an in-dash stereo with Sirius with at least 2 lines of display. I bought this unit and the SIR-JVC1 tuner; the installation was a snap.

Her car is a 2002 Forester and there was plenty of room to put the Sirius Tuner behind the dash. Running the antenna from the roof of the car to the dash was also very easy.

Pros: Great SQ; picks of FM and AM stations well (however, with Sirius, why would you EVER listen to regular radio!); Front-USB

Cons: You can't directly access a Sirius Channel (you have to go channel by channel or switch to a category); The remote is pretty much useless (I would only give the remote a 1 star ranking. I really don't like it and it doesn't work well with Sirius).

Even with the cons, I still get this unit 5 stars! She doesn't use the remote and you can program the Sirius channels you like into the 18 Sirius presets. I like this unit so much, I may have to buy it for my car.



Very good receiver, could be better

Written by: Mark from Burtonsville, MD on September 15, 2006

Pros: Sounds great, clear display even in bright sunlight, looks excellent at night. The full time clock on the display is nice, especially given that the factory radio in my car had the original clock. The USB port is why I bought this receiver and that works as well as could be expected. I am using a very small 2GB flash drive that holds enough music that I don't get tired of the repitition.

Cons: The biggest downside for me that led to a lost star is the inefficient use of the otherwise excellent display. I don't care one bit if it can display graphics. I would like to use the full width of the display for the artist/album/title information. I also really think that a player in this price range should have a pause button. And, I would like to see a mode where the music is off but the clock is displayed. Too many of these vendors are going for glitz versus functionality.

When you use the USB port, it takes a few seconds to start up. With my 2GB stick it seems to take about 4 seconds. Flipping through folders with the up and down arrows is not zippy, but not horrible either. As for comments about not starting in the middle of a song, if you leave the USB stick in the receiver or you plug it into the receiver before turning it on, it will start at the song where you left off. However, if you turn the receiver off, remove the stick, turn the receiver on, and then reinsert the stick it will go to the first song in the first folder.

In general, I am totally satisfied with the purchase, and of course Crutchfield is great. This was my 4th CD receiver purchase from them.

2000 Toyota 4Runner
Crutchfield Customer Review (What's this?)

I purchased this unit in a 4runner after a Pioneer 3700 and mp80. My main reason for buying was the usb interface and the three outputs plus 4 volts out. I have had the deck for a week and ready to return.

Pro's Cost, USB, Outputs, Volts

Con's, FM reception (very weak), use of functions, manual, unable to see display easily during the day.

Overall for the price not a bad unit. I decide to buy a Kenwood DPX-501 as it has a USB output, but superior fm reception.

Once again Crutchfield helped me with my purchase. Highly recommend to buy from this site.



Just what I needed!!

Written by: Kevin from Little Rock, AR on September 14, 2006

Crutchfield Customer Review (What's this?)

So I was looking for a car stereo that would play mp3's from CD or USB flash drive and this was it! It sounds great, it reads all my homemade CD's perfectly and the USB is simple. Just plug in the stick and it plays.

Yes, you may have to look throught the manual a time or two for some of the more advanced functions, but once you see how it's done it makes sense and you most likely won't need the manual again for the most common functions.

In fact, my wife (who hates technology) was so impressed with this stereo that I had to get one for her car, as well. She especially liked the ability to display your own pictures on the LCD screen.

So if you're wanting to know "would I buy this model again if I had the choice?" the answer is I would and I did.

I was also just as impressed with the documentation Crutchfield sent along with the unit. The instructions were simple to follow, and everything worked out just like it was supposed to. And that's why in addition to buying a second CD player, I also made sure to buy it once again from Crutchfield!



Great, affordable deck!

Crutchfield Customer Review (What's this?)

This is a great deck! I was looking for something for Sirius radio that had a great display like the PNPs do. After a lot of hunting around I found this one which seemed to fit the bill. I was a little hesitant because most decks don't provide good Sirius displays but I decided to go for it!

I was not disappointed! It's got a great read out! It shows the artist, the song, the's pefect! And it scrolls the songs that are long (most HUs in this price range don't).

It's got some great colors to pick from. After I read the manual and played around with it a little (it took a little time) everything was pretty easy to come by.

It also makes my factory speakers sound really good which is amazing! I was going to replace them...but not now. They definitely don't sound stock anymore!

I haven't tried the imaging yet but plan to soon. I think it will all turn out great! If you're hesitating - don't! This is a steal for the price!

I was looking for a deck with GREAT SOUND and FRONT aux input. I have been using this for a week now and I am so pleased with the sound quality. Navigation on my flash drive is easy. My MP3s sound better than on my daughter's IPOD. I don't need to get an MP3 player now!I simply download from the internet and play immediately in my car. If it is sound quality you are after, this is the deck! a bonus you get some really cool features for a very affordable price. Excellent deck by JVC! Installation instructions were customized to my car. Thanks Crutchfield!



very nice for the price

Crutchfield Customer Review (What's this?)

Overall , this is a very nice unit (much better than the sony's i've had). A few points: 1. The sound is very good with mp3s/cds, not quite as good but still very nice with sirius. 2.There is no fm reception issue, it pulls in more stations than most other models. The only issue I have is that the unit is not user friendly. Most adjustments have to be made while stopped and with manual in hand. I believe it shouldn't be so hard to simply turn the sub up or down. Still , a very nice unit for the price.



great stereo - you will not be disappointed

Crutchfield Customer Review (What's this?)

I have had the JVC KD-G820 for two weeks now and love it. The ability to play MP3s and WMA files off any USB stick was the key selling point for me and the feature works great. When you insert a flash stick, the unit reads the flash stick within a few seconds and displays the total number of folders and tracks found. Then it immediately starts playing the first folder and track. The multiple line display shows the folder name and the name of the track. Some reviewer said that the stereo does not resume from USB, but they were wrong. It resumes playing from the exact same spot in a song after you turn off the stereo or turn off your car. Another reviewer said it has poor FM reception, but this could not be further from the truth. My FM reception increased dramatically. I can now listen clearly to stations that I used to not pick up unless I was at least 40 miles closer to the station. I also found the controls - both on the head unit and on the remote - to be extremely easy to learn to operate. I didn't have to crack the manual at all - it was very intuitive. Overall experience with Crutchfield was excellent. I will definitely be a repeat customer.



Great sound - hard to navigate USB

Crutchfield Customer Review (What's this?)

I own a recording studio and I am a music producer. My car is the first place I test my mixes to see if it translates well in the real world.

Its the best sounding "average priced" unit Ive owned. It should make any average priced speakers sound great with ample power. Of course if you like to bleed your ears, use external amps and sub.

I dont own an MP3/WMA player, so the front USB input to use USB flash drives is the main reason for selecting this unit. This USB port is mainly for jump drives. Pluging in "players" may create software conflicts. Players should be plugged into the rear "i-pod" input or use the "external in" from headphone outs.

"Direct access" is limited to folders numbered 01 thru 12 only, too bad. Direct access does not recognize folders that contain other folders. Its normal to have "artist folders" and "album folders" in them. You can sequentially move from folder to folder one at a time or in increments of 10. Therefore flash drives with more than 2GB in size becomes difficult to navigate through. For me, a couple of 2GB sticks are enough for a long trip. Ill copy over what I want to take with me before leaving. No CD case full of CDs !!

FM reception is fine for my area. CD player is great with audio CD or MP3/WMA CDs.

Why 4 stars:
The Graphics when all said is USELESS. The 64X64 pixel image can only be displayed from MP3/WMA CD only, NOT THRU USB PORT! I thought Id use album cover as graphics. Most images were unrecognizable!!

Navigation is not user friendly. YOU WILL HAVE TO READ THE MANUAL! Its a unit that TAKES SOME GETTING USED TO!

Thumbs up, IT SOUNDS SO GOOD, & thats what counts!



USB playback

Crutchfield Customer Review (What's this?)

First off this is alot of cd player for the money. i would def recommend it. i bought this unit mainly for the usb feature, hoping it could read external hard drives. i hooked one up to it in my garage, even hooked it up to a power outlet so it had proper power and the unit did not read the hard drive. the message displayed "read failed". the unit was made for ipod type hard drives and not mass storage hard drives.
although it put a damper on the reason i bought the unit, i am still satisfied with all of the other features it comes with.



Not to be too opposite

Crutchfield Customer Review (What's this?)

I don't understand how some are claiming this has bad reception. I get excellent reception and the radio even has ways to increase station reception if you read the manual. Must be an antenna compatibility problem.

Also, this unit DOES support harddrives with greater than 4GBs. I know because I hooked up a 40gig and was able to read ALL OF THE SONGS. However, a harddrive is rather impracticle as I found out, and really isn't the way to go. The unit does not put out a solid 5V DC, and as a result it took a bit of wiring to get the harddrive to function properly. So, don't expect your harddrive to work by just plugging it in.

I'm very satisfied with the unit, it does all that it said it would. However, if I had known then what I know now, I would have gone with a cheaper unit without all the bells and whistles, like screensavers. They are just useless. I'm not holding that against the unit itself though, it's wonderful if it's what you are looking for. The sound is awesome.

USB support is not all it's made out to be.

Written by: Tommyj from Minneapolis, MN on April 19, 2006

2001 Mitsubishi Galant

I've had this deck for about two weeks and it is going back as soon as my new deck shows up. I bought it almost exclusively for the front USB input, which I had planned to use to connect my 20GB iRiver and 60GB portable hard drive. A couple things that you should aware of before purchasing this deck for the USB are that it only supports a 4GB partition, which eliminates most hard drive players. The deck will also only read 2500 tracks and a smaller number of directories. The deck also appears to have corrupted the filesystem on my iRiver when I tried plugging it in.

The deck does have undocumented support for vorbis .ogg files, but this is limited to usb connected devices, not CDs. The vorbis support also seems to be poor, I experienced a lot of skipping on normally perfect files.

Another issue I encountered was the clock display freezing. During the first 20 minutes of a drive, my clock read 8:16. I turned the deck off and back on and it displayed (and promptly froze again) 8:34.

IMHO, this deck has some serious issues and any one who is remotely picky about their electronics will be ultimately disappointed.

I purchased this CD player after owning the JVC Digifine player for about 4 years. I started looking for a new player last year and was dissapointed with most of the units that I saw, until I recently found this one. The tuner is very strong compared to most that I have seen. The screen is one of the prettiest with the rolling colors and positive/negative polarity colors that it displays. MP3 CD player is quick and sounds great. This unit has many quality features and is highly recommended. You won't be dissapointed




Written by: Adrian from Dayton, OH on February 21, 2006

Crutchfield Customer Review (What's this?)

I liked this unit a lot and here's why:

1. USB plug allows you to connect a USB stick, or even a hard drive based MP3 player (such as my archos player) through USB. This allows navigation of the music folders on the hard disk from your headunit.
2. Radio reception is great (definitely better than my stock headunit)
3. Regarding Ipod compatibility: I have not tested this feature because I do not have an Ipod but here it goes: If you want to use your Ipod with this player, you will need a special adapter that plugs into the back of the unit. Why? Because the people at apple, in all their unmeasurable wisdom, decided to lock down the Ipod with DRM. You can put mp3 songs on your Ipod as "data" and play them though the usb on the front of this unit (but then you can't play them from your Ipod)......Bottom Line: buy the adapter if you want to use an ipod.
3. The screen is beautiful
4. The pre-amp outputs work very well

1. There is no "resume" feature for USB
2. A big portion of the screen is wasted and cannot be used to display song titles. There is no option that I can find which will allow me to display song information across the whole screen.
3. This player does not have Radio Data Service (RDS). Unfortunatelly, there are almost no aftermaket receivers on the market today that have RDS (at least not under $500). This is the only feature that was on my factory radio that I wish I still had.


I'm verry happy with this player.

Crutchfield Customer Review (What's this?)

A couple of things attracted me to this unit - the USB port and Ipod compatibility. That said, the basics:
- Radio reception is ok, however my factory radio produced better
- The menu system and ability to configure the radio was somewhat cryptic and required reading the manual to understand
- The manual was/is virtually useless at explaining anything in detail
- The variable color display isn't worth the extra money
- Audio quality is good
- Plays MP3 and regular CD's well
- Navigation of the folder for MP3 CD's and devices is difficult and complicated
- I expected the radio to have FM tags to include song title and station ID like other's in the price range and it did not, disappointed.

My major gripe is with the front USB port. The ads and manual say it's ipod compatible - technically true. However, it lists folders from the raw Ipod storage format - 00 - 99. Making it impossible to play specific songs or playlists/albums/genres etc. It may work better with the $100 ipod interface. So don't expect to control your ipod from the front USB.

Windows based MP3 players intergrate far greater than the ipod via the USB. My memory stick MP3 player plugs right in and works well.

Variable-Color 3D Graphics: This unit features a full-motion 3D graphics display with variable color backlighting. Using the palette of 12 preset colors and adjustable red, green and blue levels, you can customize the display background with one of 1,728 possible color variations. The following colors are stored in memory: Aqua, Sky, Sea, Leaves, Grass, Apple, Rose, Amber, Honey, Violet, Grape, and Pale. You can choose Every (the color changes to a preset color every 2 seconds) or User (created by your own levels of red, green and blue between 0 and 11). You can select a different color for each source, or a single color for all sources. In addition, you can select one "user color" for daytime use and another for nighttime use (when headlights are on).

Personalized Image Capture Technology (PICT): Using the supplied Image Converter software, you can produce custom images to display on the KD-G820's screen. Not only can you display still images, but you can modify images so that they in effect become a mini-animated movie. Customizing the images is simple and straight forward. First, you need to capture images by downloading them from the Internet or recording them with digital equipment, like a camcorder or camera. Next, using the Image Converter software, you can edit the images and convert them to PICT-compatible graphic data. Image Converter generates a new file suitable for the head unit's display without changing the source image. After the editing has been completed, the images can then be burned onto a CD-R or CD-RW disc. Finally, the images can be transferred to the head unit from the CD-R/CD-RW disc. (See below for minimum computer requirements for the Image Converter Software)

Still Images: Pictures can be created and downloaded into the receiver and used for the graphic screen. A total of 30 large still images or 30 small still images can be shown one at a time as a static image or in a slide show fashion.

Animations: Animations can be created and downloaded into the receiver and used for the graphic screen. The graphic screen animation can contain a maximum of 60 frames for a small size animation or 60 frames for a large size animation.

Image Link: When an MP3/WMA folder includes an image file edited by Image Converter, you can show the image on the display while the tracks in the folder are played back.

USB Port: The front-panel USB port allows you to play USB flash drives loaded with MP3 and WMA files. MP3 files with a bit rate from 8-320 kbps and WMA files with a bit rate from 5-320 kbps are supported.

MP3/WMA Playback: The KD-G820 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-G820 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.

Intelligent EQ (3-Band iEQ): This model has Hard Rock, R&B, Pop, Jazz, Dance, Country, Reggae, Classic, User 1, User 2, User 3, and Flat preset EQ curves. User 1, User 2, and User 3 presets can be adjusted to your preference and stored in memory. For each preset, you can independently adjust the following:

  • Low Level: -06 to +06
  • Low Frequency: 60Hz, 80Hz, 100Hz, or 120Hz
  • Low Width: Q1.0, Q1.25, Q1.5, or Q2.0
  • Mid Level: -06 to +06
  • Mid Frequency: 500Hz, 1kHz, 1.5kHz, or 2.5kHz
  • Mid Width: Q0.5, Q0.75, Q1.0, or Q1.25
  • High Level: -06 to +06
  • High Frequency: 10kHz, 12.5kHz, 15kHz, or 17.5kHz

Amplifier Gain Control: When you are using the KD-G820 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.

Source Naming: The KD-G820 allows you to assign names of up to 10 characters for AM and FM stations (30 station maximum), and a name up to 8 characters for a connected external component. You can also assign names of up to 32 characters for CDs (including a connected CD changer, but not MP3/WMA/USB or CD Text discs--30 disc maximum).

Subwoofer Output: In addition to the 4V front and rear preamp outputs, this unit has a set of 2V subwoofer preamp outputs. The subwoofer output has independent level control, adjustable from 01 to 08, and a selectable low-pass crossover. You can select a cutoff frequency of 80, 120, or 160Hz.

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-G820. 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-G820.

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.

Clock 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). Also, this unit has a timer that allows you to turn the dimmer on for a period of time each day. The timer allows you to select a start time and an end time for the dimmer.

Note: The amount of dimming is fixed, it cannot be adjusted, and the illumination wire must be connected for Auto operation.

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.
