Pioneer DMH-W4660NEX Review 

Got this radio today by accident, all I wanted was the ability to play my hi-res flac files and got a full feature upgrade lol

Hey FYI, Time Alignment is how you adjust the delay for the sound to your ear based on location and distance. It is a key feature to getting your soundstage setup correctly, a very very important feature.

FINALLY! The video I was looking for! Was debating between the 4660 and one other. And now I know which way to go! Great video. Thank you!

I just got this unit and this by far was the best review thank you sir.

I do appreciate this video since I bought this radio and am about to install it. Fyi, 'that crossover thing' is quite important to have decent radio music quality.

getting this installed sometime soon, just picked it up waiting on my wiring harnesses for my 2014 rav4

Perfect review, really informative and succinct. I have a '13 Toyota Sequoia and I just put this in. Doing so, seemed to knock my Boyo backup camera offline. :0( Crutchfield is sending me a new one. Anyway, my main question is this has video out does it not? I want to put in a 43" TV in the back for the 3rd row so when we go camping we have a rolling entertainment center. This has HDMI I do believe, could I run a power inverter, the TV with FireTV on this beast, connected to mobile hotspot? I am thinking about just getting a separate always on mobile hotspot it'd only be like $25-50 a month to add to my bill. I have 2 12" JL Audio W1 300W Subs mounted in a powerwedge box in the very back & a 1000 Watt Crunch amp driving them. My main question though is about the setup for the TV. How will that work? If it will work? A lot to unpack there but just need some advice.

Best review I found so far, thanks. How much did you pay for this unit? and is it easy to install?

When i connected my harness i had no where to put the parking brake wire. Because its an old car. Is there a way i cam trick the system into thinking i have it connected? Also lots of my features are not working on the unit i got. Android auto icon is not on home screen. Date amd time are not working. Wont let me set. Did i get a broken unit or what is going on?

great video did you have to buy a aftermarket back up camera or did it work with your original stock back up camera? I have an frs and want to this because of apple car play thanks in advanced !

Great video! I have a BRZ and I'm looking into buying this HU, did you have to buy another rear view camera? or does this works with the OEM one?

Great review! Question, I know the 2660 has weblink which this unit doesnt show as having on Pioneers site - is there a way to access RU-vid, etc like the 2660? Thanks!

My I ask what is the lowest subwoofer frequency? On this model?

Hello Demon, Is there a way to do the mirroring option wirelessly in order to watch videos from youtube or any other app? Thank you for the review.

I just bought this today android auto is not working. And the time is not working lots of settings are greyed out. What did i do wrong? Also i do not have the android auto app available. Its not showing up.

This is quite useful - thanks. I installed my unit over the weekend. I really like this unit. I have a couple problems I hope someone can help with. #1: For some reason, the unit is asking that I attach the speed sensor. I don't see a speed sensor in the box. What am I missing? #2: I have not been able to update the software via CarAVAssist. It would not connect, then today, all I get is "download failed."

What was the thing you used to get the gauges to show called?

Whats the difference between this and the 2660?

I know its kind of a random question, but do you notice that the backup camera picture on this head unit seems a little bit faded compared to other head units?

Can this be installed in a 2011 Hyundai Sonata gls?

I really appreciate the video I just got this radio put in yesterday and could not figure out how to connect to Wi-Fi but your video helped me with that. The only other thing is I cannot figure out how to accept the internet communication service terms an agreement. It will not allow me to use Alexa. The agreement came up once when I connected via hotspot and when I tried to click on accept it wouldn't accept it. Do you have any idea what's going on here? Thanks

Great video. Do you have to push the button for google or can you just say "ok/hey google"

How does the screen handle glare out here in the Vegas sun? I want to put one in my F-150, but the glare out here gets to be absolutely insnane.

My maps stopped working properly, do you know how to fix it?

Great video my friend. Excellent walk through of features. Could you do one on screen mirroring. I was told that I can mirror my phone screen wirelessly to the unit. However, I can't figure out how to do it. I'm using a Samsung Note S10. I would appreciate any guidance you have. Thanks

Were you able to use factory mic or you has to use a new one that come with radio

Can you watch RU-vid music videos while the car is in drive?

Does the wireless Apple CarPlay/Android Auto only use Bluetooth to connect or need some type of Wi-Fi or hotspot connection?

I don't like that I'd have to use my phone's Hotspot. Any way to know which radios I'd have to use that feature?

I love this review! I went out and bought the 4660 and use this review as a guide to learn how to use all the features! So thank you! But I do need help! HOW DO I SET THE CLOCK?! I went into clock settings and I see everything but a way to change the actual clock settings! Help!

By the way I can see why you like Android Auto better than Alexa. With Alexa you have to constantly be connected to your Pixel 4 via hotspot. Not good if you're limited on hotspot data. Isn't there a way to use the Pixel's wifi without using hotspot? Just like the Amazon Echo Auto does?

What’s the difference between this model and the Pioneer AVH-W4500NEX model?

Does this model have wireless screen mirroring for IPhone?

I just got this head unit but i cant find a firmware update if there even is one pioneers website dont even have a listing for the dmh 2660!

While using CarPlay and trying to change the channels using the steering wheel controls the radio will start to channel surf and doesn’t stop. Anyone else have this issue? This unit was installed on a Toyota FJ.

Is this on a BRZ? It looks like my dash and cluster. That way I know it’s compatible with my car all the gauges and tire pressure features

Hello an good evening. Excellent video, very informative. I was just wondering if I have Alexa is it possible for me to set my alarm as you did with your Google Home?? Thank you for your timely response

Can the GPS be used without the phone. Other words is the GPS built into the unit? Thank you

hey i oredered 4600 model but they sent me 4660 model i was wondering whats really the difference between the two models? big thanks man

good vid!

Just curious, what car did you install it in??

Great review its 2021 how is it working now

What’s the difference between this and the 4600NEX?

How can I mirror my android (Samsung note 20) to this radio? What is the HDMI port for?

Will installing one of these mess up my car warranty?

Man, you are missing out on some serious features with your sound quality! The time alignment and your crossover slopes are huge!! I have the model under this one and they don’t have either one. I’ll trade you. Lol!

I'm having issues updating the firmware on mine. I've tried two different usb drives that were the correct format. I keep getting an error notification.

I just put this in today and lost steering wheel controls. Volume works, but I can't skip songs forward or back, can only seek in the current song. Crutchfield seems to know about this issue, but doesn't have a solution. Did you have the same issue or did you find a workaround?

Just got this unit. I don't have an android auto button. How do I make this show up?

Trying to use RU-vid it’s not letting me . It’s telling me to accept internet communication service but it’s not letting me accept it . Can some one help

My original USB port isn’t working anymore after installing the stereo! Any idea why?

What app do you download?

I just got this radio today and don't understand how it works and how to work it. I bought it from Best Buy and had them put it in. He wasn't very knowledgeable about telling me how to work it from my Samsung Note 10 + he has an Apple phone. Can you please help me to understand this radio? I'm ready to return it. Also, for some reason it won't let me update it either.... Please Help me to watch RU-vid videos and to work the system all together.

which is better? the 4660 or the 4600?

This has integrated GPS. Why would you still need your phone?

hi, can you play youtube on your unit?

SCREEN SIZE ?

this stereo plays youtube videos or no

I am not sure what is going on here, but either people are getting paid for positive reviews or something has drastically changed between when videos like this were made and now. As a result, I feel the need to let people know a real (and current) review of current Pioneer NEX radios. About a month ago (Jan. 2023) I purchased and installed a Pioneer DMH-W4660NEX stereo for my truck. Before installing I bench tested the unit. While Bluetooth, Wi-Fi and WIRED AppleCar Play worked right out the gate, WIRELESS CarPlay was giving me one hell of a time. The thing just didn’t want to connect wirelessly no matter how many times and ways I tried. I finally got it to connect by deleting all the Bluetooth, Wi-Fi and CarPlay connections from both the phone and head unit then connect the phone via USB. Once I did that it asked if I wanted to connect wirelessly to CarPlay. After saying yes, it worked MOST of the time. I would still need to reset tethering each time I wanted to connect to the unit, but I could force it to connect that way MOST of the time. I then decided to install the stereo in my truck, well since then it has NEVER connected to CarPlay wirelessly. Again, wired is fine, but wireless was not. I wish I could say that is where the problem ends, but the unit actually gets worse the more you use it. I also need to add that I have the lates iOS installed as of 1 Feb 2023 (16.3) and the lates firmware on the stereo (version 3). I should also add that I have two other people that work with me that recently installed NEX radios as well and they ALL have the exact same problems as well. We have tested on both iPhone (12 and 13 Pro), Android, and on two different stereos (DMH-WC5700NEX and DMH-4660NEX), so you cannot say it is an Apple or Android problem alone. Below are the current problems with NEX stereos: 1.) Will not connect to wireless CarPlay and Android Auto 2.) Unit pops up a message saying connection problem, yet unit shows a Bluetooth and Wi-Fi connection to phone. 3.) When clicking on the phone icon on the stereo it is not showing a connection to phone. If you look at your phone it will say connected, but if you tap the already connected Bluetooth connection on your phone it will now display on the head unit. 4.) If you shut off your car you will need to turn off tethering and back on before it will connect. Sometimes more than once. 5.) The Pioneer “CarAVAssist” program launches itself every time you are in the car with the stereo on. The freaky part is no matter how many times you close it the program will keep launching itself as long as the stereo is on. The only way to stop it is to delete the app. 6.) Stereo keeps dropping and reconnecting the Wi-Fi connection when driving. 7.) Stereo sometimes starts up to a black screen that won’t go away and no sound. Only way to fix it is to turn the vehicle back off and on. As stated at the start, not all these problems you will see at once, but within a couple of weeks you will see them, and these problems don’t seem to go away. The problem exists with both Android and Apple devices and across multiple NEX units. I have already contracted Pioneer, but they will not respond. Best advice I can give is to buy any other stereo that doesn’t say Pioneer. I am sure Pioneer know of the problems plaguing NEX units and needs to release a firmware update to fix all these issues now or I will be installing a new unit that says “Kenwood” on it and never turn back.

Did he say “mass air pressure” lmfaooo! I could’ve swore mass air flow was MAF not MAP lol

Can you watch RU-vid music videos ??

I do music so I must have THAT CD quality sound there is no sustitute for that cristal clear sound when you have a custom sound system .there is nothing like that cd sliding thru the slot

Can you watch RU-vid videos on the screen man

Nice flag 😎

Slooooow down! All I saw after a few minutes of fingers bouncing around the screen with babbling in the background. Not at all helpful.

Somehow you think waving your finger in front of the radio means something or points to something. It doesn't.

how do you watch RU-vid with this unit?
