I'm very happy with Kenwood DNX6140, works as it supposed to I didn't have any problems at all, the sound is perfect, the directions with GPS are great, the bluetooth works perfect with my cell, I recomend this product. Sonic customer service is great to help you with everything you need. Thank you.

Overall the Kenwood DNX6140 is an outstanding product. There are two things I find a bit annoying. When connected to an ipod if you select a playlist with just a few songs, it will play them over and over ...

Second, the volume level for audible instructions is quite loud and as far as I can tell is not adjustable.

Product arrived and functioned as expected. Nav is excellent as well as the bluetooth. I really enjoy putting my music on thumb drives. Still finding new features on this unit. Ver satisfied with the purchase.

Review written by James from Clint, TX

I liked this nav unit so much (over the competition) that I've installed 3 of them so far. You get the best of all worlds: Kenwood for great sound; Parrot for cutting-edge Bluetooth technology; and Garmin for GPS. Rather than trying to re-invent the wheel Kenwood wisely let each of these three features be designed by the three best companies in each category and seamlessly integrated all three modules into a robust, easy-to-use and fully-compatible product. I can't say enough good things about this unit. After a couple of years messing with the competition the first install of the DNX-6140 was an "Ahhhhh" moment.

Let me tell u, I made the SMARTEST decision picking this headunit over the F90 from pioneer. The #1 reason? LAG AND BOOT UP TIME!! Here are some specs i have on my kenwood:

Startup time: AMAZINGLY FAST for basically a computer loading up. I have music playing in about 10 seconds (hooked up to an ipod, dvd, radio, or aux port in front) and the gps is ready to go in about 23 seconds.

Bluetooth sync up: about 10 seconds, i'm ready to make phone calls. I can even send TEXTS!! Yeah u heard me, i can read and send texts through my headunit!! It's the bombest stuff. However since my phone is older (samsung sync) i have some trouble with it, but i don't text while i drive anyways so i don't use the function much.

DVD playback: I did the ebrake mod. All i did is when ur wiring up the pin harness to the radio harness, u gotta ground the light green wire that's for the ebrake. Now i can drive and watch dvd's and also use the navi to type in a location.

Ipod connection: The ipod hookup is literally instantly. 10 seconds and it's playing music. I have only 2 MINOR downfalls to the unit. The navigating through the headunig is extremely fast and quick to find songs or playlists, there is NO lag!! One of them is that the headunit has a memory function. Let's say ur listning to ur playlist and ur on a song and u plug it in to the car, the headunit will continue to play where u left off. Very awesome featuer. HOWEVER, if u turn off the car with the ipod plugged in and turn the car back on, u will clear out the memory and ur music will start from the first song (so mine is ABC123 by the jackson 5 [RIP MICHAEL JACKSON U WERE THE GREATEST!!!]) so i'd have to go back and find the song. Not a huge hassle but it does get annoying if u don't disconnect ur ipod.

Another minor thingie. I keep music videos, cartoon episodes (mainly family guy, simpsons and spongebob) and LOTS of movies on my ipod. When i watch them using the ipod dock connector, for some reason the picture gets stretched and i lose about 3/4 inches of the picture on both sides. I thought it was zoomed in but it's not. Nothing huge but u lose a little bit cut off the sides. THIS DOES NOT DO IT WITH DVD'S. U see dvd's perfectly, only when i watch movies/music videos/cartoons through my ipod. Maybe i'll figure it out, but i got over it (and i'm a perfectionist!)

DVD playback: I watch dvd's while i drive, so? I listen to it it's funny listening to spongebob going to work. The navigation is very simple. You touch a portion of the screen and it allows you to highlight the dvd title screen or functions. Super clear and crisp video while watchin dvd's! Amazing quality!!

GPS: Okay this was a dealbreaker for me for sure. I LOVE the navi on this thing! It's powered by garmin and so it ALWAYS has reception and it's PINPOINT accurate! The instructions states that you have to mount the gps antenna on the outside of the car, but behind the headunit there is a long metal rebar. I just stuck it to that (magnetized) and hoped it would work through the plastic of our dash. I have ALWAYS full reception all the time!

Sync up time to a satellite, literally seconds. Re-routing is also very fast, taking only about 4-5 seconds on how to get back on track. The screen is also very crisp and clear and is easily readible.

Radio: right now i'm using just the regular tuner, but i'm gonna get an HD tuner very soon. The radio however is very strong and comes in clear, a LOT clearer then the oem headunit. I also love it cuz u can customize the radio station settings. It also picks up the data from the radio (like on KISSFM it will tell me what song is playing and by who).

Equilizer and settings: There are LOTS of settings for this unit. No joke, there is a crap load. I'm still getting used to it and still learning about new functions. The equilizer is a bit hard to understand and a little difficult to find that sweet spot where the sound is always clear, but i'm almost there. I've only had it for a week, GOSH! lol.

Design: Definitely a HUGE decision maker between this and the F90 because both of them have rotary volume knobs. I HATE button volumes and prefer rotarys. One reason why i picked the kenwood over the pioneer is because you actually have something to grab onto. The wheel sticks out about 3/4 inches thick and it's fully rubber, so grabbing it is no problem. The pioneer is only about 2mm thick and might be a bit to grab on, especialy because the rotary also has buttons (u can push it up, down, left right). The kenwood only goes in for the att function for quick volume dimming (po-po).

The buttons on the side has quick access to GPS, telephone, rear view camera, and turning off the unit. The display also has a million colors to choose from so u will find that perfect color to match ur interior or any color u desire.

All in all, i made a GREAT deicision picking the kenwood dnx-6140 over the pioneer f90BT because of all the facts above. Would i buy it all over again? HELL YEAH!!

I bought this unit after having purchased a Pioneer AVIC-F90BT that turned into a brick in a week. So far I love it. It is simple, yet well laid out. Great resolution from any angle (I have an older 4Runner where the stereo is mounted low). Loads fast (usb, iPod and DVD's). Great on screen controls with easy to follow sub-menus. I only have 2 complaints:
1) Either rear output or Sub output, not both (which I've gotten over).
2) Garmin map is a little cheesy (cartoonish).

Overall I'm very happy with this deck as well as the great price and customer service I received from Sonic. I would recommend this deck to anyone looking for a reasonably priced NAV/DVD Stereo.

This is the unit to get if you are looking to get if you want an all in one ! the GPS is great, the bluetooth is a great feature, and the screen quality is excellent when watching a DVD. It was well worth the price, and of course you won't be sorry with the Kenwood name. A great deal from Sonic.....
