Kenwood DNX8120

Intro
This is Kenwood's top of the line Excelon model for 2008. It is a double DIN unit that features a 6.95" touch screen lcd, builtin bluetooth, builtin Garmin navigation, 5volt preouts, iPod and USB inputs, satellite radio ready, and remote. It carries a 2 year warranty if purchased from an authorized dealer.

**Update: There was a recall on these unit right before they were suppose to ship to consumers. Apparently there was a bug in the firmware. All updated units through Kenwood will have a round green sticker on the box saying Certified Upgrade.

Installation
Installation is pretty much straight forward if you’ve done car stereo installations before. It is a D-DIN unit so you’ll need a dash opening to support that size. I installed mine in a Lexus GS using an OEM kit to fit D-DIN size units. Using the predrilled holes on the bracket, the unit sticks out about ½”. I had to drill my own holes to get the unit flushed. You’ll also want to make sure you have plenty of depth because there are a crap load of wires in the back. Good thing they have it where you can disconnect wires you don’t need (A/V inputs and ouputs, relay wires…). Video and nav bypass is simply grounding the parking brake wire. There is no speedometer wire to connect but the speed reading in nav mode is quite accurate.

Screen
The screen is not quite 7” but very close at 6.95”. You probably can’t tell the difference anyways. I don’t know the exact resolution but from the text and layout it’s more than sharp enough. DVD videos are nice and clear as well. I don’t own a iPod so I can’t test the audio or video (iPod video) quality. Touch response is good but there were a few times where I had to press 2-3 times for the screen to detect the push. A tactical feedback feature similar to Alpine’s PulseTouch would be very nice so you’ll know when the unit has acknowledge the command.

**Update: There's also numerous screen angles you can set it to. There's even a reverse angle where the screen angles down instead of up. What's neat is that there's a memory setting so everytime it starts up it will move to that angle.

User Interface
I haven’t owned any previous Kenwood units before so I can’t really say how much of an improvement there is but I can compare to other brands that I’ve own in the past. From my experience Alpine and Eclipse have a much simpler and easier to use UI. But I do understand that this unit packs a lot of features and settings so it’s going to be tough trying to make the UI as simple and easy to use as possible. I think Kenwood did the best they can given all the features and settings that are required. I also noticed that the UI is a bit slow at times to respond, probably due to the complexity of all the menus. This is just for the buttons on the screen; the physical buttons at the bottom responds instantaneously when pressed. With the Alpine and Eclipse, the UI responds instantly whether it’s a physical button or not. Another small quirk I have is that the physical buttons at the bottom are a bit too small and at times have had trouble finding the right one. The buttons on the screen however are nicely sized and easy to read.

SQ and Sound Processing
I have not tried listening to a store bought CD yet (haven’t bought CDs for awhile) but I have tried MP3s ripped at various bitrates. Usually files 192kbps and up sound excellent to me. 128kbps still sounds great and is a good compromise between file size and SQ. I do notice there’s quite a bit of background noise when switching between MP3 files and folders regardless of bitrate. Seems the unit does not use any type of muting when switching between files/folders. I don’t know if this occurs with CDs or DVD-Audio discs (supported) though.

**Update: I tried it with CDs and there's little to no gap between switching songs. I didn't notice any noise between skipping tracks either.

This unit is just packed with various sound processing features. I won’t go into detail of them all but I’ll list what I can remember. There’s a 13 band equalizer that you can set separately for the front and rear speakers. There a couple of presets and 1 custom available. There’s full time alignment for all speakers as well as front/rear speaker sizing with adjustable crossover points and octave slopes. There’s also SRS WoW surround sound settings. All sound processing can be bypassed.

Navigation
The navigation is based on Garmin software and maps. The map data are stored on a removeable SD memory card. It can be remove whenever there are updates available on the web. Initially I thought the UI and map looked a bit cartoon-ish but have grown to appreciate the simplicity and ease of use. Accuracy is spot on and all directions are given in a clear and understandable female voice. Freeways, streets, and locations are pronounced but pronounciation can be off some times. Routing and re-routing is very quick at about 5 seconds. It is capable of multi-tasking (nav while listening to music or watching a video/movie).

**Update: So far it has failed me twice. Once I tried searching for Beverages and More and no matter how I tried spelling it, it couldn't find any at all. The other time I planned the route while the car wasn't started and after I started the car it got all confused. Even though the destination was still in memory the directions were all off and it had to reroute me numerous times.


Bluetooth
Setup was quick and painless. Got my phone connected and phonebook synched in about 5 minutes. You can record a name for each entry in the phonebook for voice recognition. It doesn’t automatically dail the number, just pulls it from the phonebook. To make the call you’ll have to press the Call icon button. My phone has voice activated dialing but I don’t believe the headunit supports this. On my previous pioneer with BT that supported voice activated dialing I just press a button and say “Call *****” and the phone would automatically call that person. I don’t believe this Kenwood has this feature.

As for the SQ, the other person’s voice came through loud and clear. You can set it to come only from the front right, both or front left speaker. I have the mic on the top of the pillar and the other party says they hear me just fine.

**Update: Also supports bluetooth audio so you can connect a bluetooth device (phone..ect) and play music from it. SQ isn't that great with my phone but it may be better for others because it most likely depends on your source file and the device. You will have to manually connect the BT audio every time but the phone functions will synch automatically once the unit is turned on and your phone is within range.

USB
I told myself this was going to be a necessity on my next headunit. I bought a 1.8” laptop hard drive just for this. USB input is still quite new in the car stereo world so I was a bit skeptical on the performance. Unfortunately I was spoiled by the USB performance on the Pioneer so I was a bit disappointed with the USB on the Kenwood. Scanning took about 30 seconds on the Kenwood but the Pioneer was way faster at 5-10 seconds (depending if I unplugged the drive or not). Add on the ~30 second bootup time on the Kenwood and it’s about a minute from the time you start the car to when it starts playing. In less than 15 seconds the Pioneer starts playing already. That minute seems like an eternity compared to 15 seconds. I was hoping file/folder changing was going to improve once it scans the drive but was disappointed as well. File/folder changes took 3 seconds and during that time no more further inputs are detected. For example if you want to skip 3 songs forward you’ll have to press >>, wait 3 seconds, press >>, wait 3 seconds, press >>. Changing folders was just as frustrating. File/folder changes on the Pioneer was instantaneous; skipping 3 songs or 3 folders required only >>,>>,>> in successions with no waiting in between. Although this definitely needs improvement it’s still tolerable but I would have expected better performance from a $1000+ unit.

**Update: Apparently the usb port only supports audio. I have not been able to get it to read anything in the Video folder (grayed out). Same files in the folder burned onto a CD or DVD plays fine.

Other A/V inputs and outputs
I have currently have no external devices so I didn’t even bother connecting the A/V wires to the back of the unit. If in the future I decide to connect any a/v device I’ll give an update on the performance. It does however have 2 video inputs, 1 video output, and 2 switched power outputs (to control fans, motorized amp racks…ect) controllable from the headunit.

Remote
This thing looks like it can control your whole home theater system and more. Probably a good 30-40 buttons and many of them have several commands if you slide the switch on the side (DVD, NAV, CD...). Definitely going to take awhile to learn the remote by touch. Range and angle are very good though.

I tried spelling it completely out. I tried it as BevMo, Bev Mo, "Bev". Still no go. Maybe I need to update the map/data?

I believe it does scan at every start up. If you have a CD playing before shutoff, it will start playing the CD again before it completely boots up. If it's the HD as the last source, it boots up, goes to USB as the source and scans about 15-20 seconds before playing. If you unplug the HD and make any changes, when you plug it back in it will prompt you to update the database and won't play anything until you do so. So basically it takes about 45 seconds to start playing from USB from start up.

I have the previous generation Garmin one (that I'm selling), and I just typed in "beverages" and a bunch of beverages and more popped up. Granted, I was north of Fresno at that point, but unless its less than a year old, it should pop up.

In trying and failing to get pics on my 8120 to use as custom backgrounds, I found that the usb can be used to load them as it let me pull out and store in memory a cd cover that can then be used as a background.

So the usb can do audio and pics so far so I'm assuming eventually I can do movies or other video off of it as well.

^^ You know the 505 doesn't come with navi? you either have to get the blackbird 2 to utilize the built in dock or you can get the external navi the nve-872a that integrates with most alpine screens. Just from reviews, the blackbird 2 isn't worth close to its msrp. I was thinking of the w205/bb2 but refused to pay that much for a portable navi where it got some horrible reviews. I'm not positive, but i don't believe the 505 comes with bluetooth as well. The kenwood on the other hand has navi and bluetooth built in.

Others can chime in on the other things like display (seems that the 505 has great resolution) and such.

I you want to go pretty in depth with your sound then I would say the 505 because you can easily run a processor with it while on the other hand...

the 8120 would be your choice if you really want the navi which so far hasnt failed me and comes with built in bluetooth that also has worked well for me so far, while the hd radio portion of things is an option for both but I havent been able to actually find one in stock anywhere yet. That might be because Pioneer came out with theirs and it was terrible I heard, or at least the ones people tried to use with their pioneer radios.

You can also get the excelon x4r kenwood amp that has dsp on it if you want to run a set of 2 way components actively up front.

Both can be used effectively with an ipod, I checked out the kenwood's ipod interface on youtube, where a demonstration from CES was posted by Kenwood so you can check it out there, and there probably is one with the w505 as well.

So if your looking more for those features then I would say Kenwood, as it doesnt sound like you want to run a processor with active 3 way fronts etc.

I've owned a 3 Kenwood DDs and 3 Alpine DDs so I'm pretty well versed in them. Simply, the HORRIBLE control routines alone would keep me from buying another one. Yes, the Kenwood is BY FAR a better value but when you want to rip it out of your dash and chuck it down the road every time you get into your car it won't matter, will it? :D
I would consider a Kenwood again if they totally revamped their UI, even though they don't sound as good as the Alpines.

Thanks guys for the responses. I didn't want to get crazy with a new system, but wanted a high quality unit with easy use, good clarity and be able to have quality interface for iphone, ipod, HD, and sat radio (sirius).
It's just hard to tell on the limited info on each on which is a better choice.
Any other advice from you guys would be really appreciated!!!!
Thanks again for helping!!!!!

so basically check it out first to see if you like it, I like the ui on the 8120, especially the navi which is miles ahead of the alpine one and easier to use at least when I tried it out.

as far as sound the alpine probably only has a real advantage if you want to run an involved active crossover, the kenwood still does fine with the dsp on its excelon amp with a tweeter and woofer setup.

but yeah try them both out to see which one you like, somebody should have either one on display near you, and know what features you want to place emphasis on while taking into account each units focus.

I have been trying to research this as much as I can so I don't get any surprises.
Any of you use an iphone? Any issues with the operation or using the address book. Also I want to get a new ipod and want to be able to use the album art and song videos. Does this support the new ipods? Does anyone know where to find a video of the nav system and does it have the zagot reviews?
This is a great forum and you guys have been great. Thanks!!!

Yeah, the control routines BLOW. Too many button presses to get things done, confusing menus and sub menus, and when you put in a DVD you have to manually cycle the video even though the audio switches to DVD automatically.
The GUI is very pretty though.
I'll agree the Garmin on the Kenwood is better than the Alpine BBII but the external navi unit is hands down the best navi on the market IMO.

The new kenwood supports video with a 30 dollar adapter which I bought but the with the stock connector it comes with you can only do audio.

I'm almost positive the w505 also does video from the ipod as well, but you might check that thread for specifics on what it can do as bikini punks thread on the w505 review has a lot to read.

Video is available of those features in you tube in a video made at the electronics show by Kenwood. Just search and you'll find it along with a few other videos people have posted with the 8120.

:changed my mind here it is, you can look for others as well

I have used most of the portable nav units and the garmin is by far my favorite. not that it is the best at everything but works very well for everything, no real weak spots like most of the other units
 
#19 ·
Hey Quality,
Sounds like you have a great knowledge base here, thanks!
Good video thanks for the link.......do you know of where I can look at one on the nav unit? Haven't been able to find one on my searches.
The UI is much better in your opinion w/ the Alpine unit?
Thanks again for your help.

I've had my 8120 for a few weeks and so far I love it, except for the faint background noise/hiss that HMoob seems to be hearing. I hear it in between songs on the ipod and most of the time while Sirius is on. I gotta figure out whats causing that.

I love the UI of the Garmin, very simple and intuitive. So far the mapping is spot on. The UI of the unit itself is simple to browse around in once I figured out the lay out. I like to push buttons first, then read the directions later. I had it pretty much figured out in about 20 mins. without the book. I needed the book later to figure out the sound settings, but the basic functions were fairly simple to get the hang of. The graphics are nice and the layout is simple.

I have the ipod cable and it allows me to use my 5G ipod video very easily. I play movies off of it and the album art work is a nice bonus. It scrolls thru songs pretty quick.

Other than the annoying hiss, the unit hasnt given me any problems. It was a "certified upgrade" unit when it arrived. I havent played with the Bluetooth yet, but everything else works fine. I had originally thought the hiss was a grounding problem or something in my amps, but I'm glad (more relieved) to hear that someone else has it too.
