User Reviews about JVC KW-NT1 Double-DIN Navigation with 6.4-Inch Widescreen Receiver with Detachable Touch-Panel Monitor - DVD CD USB SD Card - iPod iPhone USB 2.0 Bluetooth

Bought the JVC KW-NT1 for my H3 Hummer and added a rear license plate back-up camara and JVC compatible Sirius radio adapter/interface to it. Also had the DVD/parking park setup disabled so it plays while in drive (illegal in most states so check). We drove to Montreal from CT the day after it was installed so I had plenty of time to fool with it. The Navigation system was easy to use and spot on. At one point I thought it was wrong as it instructed us to turn left at 300' when we could plainly see the Richelieu river on our left! Well, guess what? We turned left at 300' and there was a ferry waiting for us! After that I learned to trust the GPS. The video controls are touchscreen and easy to navigate and eject a CD/DVD. Bluetooth was easy to setup. In fact, once I set it up, it automatically connected to my phone everytime I got in the H3. Voice connection via bluetooth is clear and problem free. IPOD hookup was easy to use. Just plug it in the front jack and push play. I also like the feature that lets you put in a greet and exit voice for when you turn it on and off. I put in, "Hello Handsome" to my wife's chargrine! Having a detactable plate is a great option because of the theft of GPSs in our Mall parking lots (stop being lazy and put them away or you will find your window smashed when you return to your car!) The only gripe I have with the unit is there is no 'OFF' button. It only turns off when you turn the car off and open the door. All in all I am happy with the JVC system and would recommend it to my friends. -- JVC KW-NT1 Double-DIN Navigation

I have owned this unit for a few months now. This is a very solid unit. I haven't experienced any glitchy behavior like lock ups and everything works pretty much the way it should. I have a 16GB SD card loaded into the unit that is filled with MP3s (JVC does not list the unit as SDHC compliant but it is). It is a no frills unit though. Screens cannot be customized and look very plain when you are just using the AUX input. No Bluetooth audio streaming, no upgrade path to HD Radio (if that matters to you), and DVD playback is stereo only. DVDs look and play just fine, though I rarely use that function. The unit loads up very quickly though, routes are calculated very fast, and the everything is laid out so simple there is really no need to even read the manual. No problems with Bluetooth; people I talk to report they can hear me just fine. I just have to figure out how (if possible) to get the unit to display the caller's name. Right now it only displays the incoming phone number. Since I don't memorize all of my contacts' numbers, I may not know who is calling. And yes, I did transfer my contacts to the unit. I wish the built in crossover had a little more flexibility, but that is to be expected for a unit like this. It powered my factory speakers just fine (much better than the factory unit), but I eventually disabled the built in amp when I upgraded speakers and added an external amp. Make sure you ground the parking brake wire to get full functionality when driving. This head unit has a detachable face. Not too many double DIN Nav units like this have it and it is one of the reasons I went with this unit. The only real shortcoming I feel this unit has is the volume control. It is touch sensitive and the area where you control up and down is really small. It will not work if you are wearing gloves. It will take time to get used to it while driving (trying to keep eyes on the road) as you initially fumble around trying to find it. It is further obstructed if you plug in a USB flash drive. I eventually ditched my drive and went with a SD card. I'm okay with the volume now. Lastly, you can use any composite video source with the front A/V input. Just buy a cheap iPod or Zune A/V cable with a 1/8" minijack. Next spring I am going to add a back up camera. Overall, I like this unit a lot and really have no major complaints. -- Well implemented functionality. No frills.

I have had the JVC stereo for about a month. Installed it myself in a Ford truck. All that was needed was a wiring harness (recommended) and a dash kit. Bought both of them at alocal electronics store for about $40. Took about an hour to wire everything and about an hour to install in the dash, run the GPS and Bluetooth cables. EASY! Unit fired right up and works like a charm. GPS is better than in my Lincoln! Love the DVD player. All features can be used while driving if you ground the emergency brake wire coming from the unit, however illegal in places. Haven't noticed a volume control problem like I read about in other reviews. Only wish it had a remote control. -- Love the stereo

I have an iPhone and therefore no phonebook in the kw-nt1. The kw-nt1 will not download a phonebook via bluetooth. The phonebook needs to be uploaded which is something the iPhone does not do. I didn't have this problem with previous radios. This would not be so bad if I could manually add phonebook entries into the kw-nt1 but there is no option for that. So basically, I have no idea who is calling unless I know the number and unless I know the number I can not call anyone. I have to make calls with the iPhone and then choose the kw-nt1 as the output. The microphone is a disappointment. My calls are short because no one wants listen to the echo or my voice clipping in and out. I've had much better mics in the past.

There are no Nav map updates. Crazy. There are 6 million POIs but the ones I'm looking for are not in there. I use my iPhone Where app to find the address and then plug the address into the kw-nt1. Disappointing. You can add new POI with the Street Director Assistant. This is a horrible application. Search for the same thing twice and you get different results. I was also surprised to find that NY State only has 10 bars. I thought there would have been more. Use it and you'll see. If you do find your POI, you can add it to the SD card (only up to 99 POIs on the card). You then need to put the card into the kw-nt1 and leave it there. It does not copy the new POIs over. Disappointing. Also logistically, it's kind of silly. How do I know what POI needs to be added to the card until I already need it? Maybe I just need to browse through the 6 million to see if everything I want is there. Disappointing.

Playing music for my iPhone is ok. The interface is a little clunky (compared to the iPhone) but very usable. My only complaint is it takes 5 seconds to load the album art. During which time, you can not move to another song. And it does this for ever song even if it is in the same album and already has the art work.

It does not offer HD radio.

The button colors are blue and do not change to match your dash. Disappointing.

With all this said, it's still one of the best options out there (sadly). I haven't found any truly spectacular radio. They all have major flaws. It so happens that I can live with the kw-nt1s flaws balanced by it's pluses (detachable face, fast route calculation, iPhone music control, bluetooth and nav are integrated, steering wheel controls module, fast boot speed). Most of the flaws can probably be fixed in firmware updates. JVC does not list any future firmware release dates so who knows. It would be great if they made it open source. Then we could fix it all ourselves.

One last thing, the firmware version that came with the radio did not work with the iPhone. I had to upgrade to the latest version before I could play music. -- it's ok if you forget how much you paid
