Ok , This Post is for information and help for other people on this forum.

I purchase this Head Unit and I found that it is ok BUT I still have to test the reverse camera, the front camera and all the other features. But lets start with the first step, The sound quality. I was trying to get it sound right , but it just cant.

I have an aftermarket Amp ( Kenwood X801-5 ) and a sub Audison and a pair of Blam 165.100. And i can say that i try everything to make it sound good on the head unit. Until we swap it for a Pionner, then i saw that It is the Machine the problem. It cannot deliver a nice powerfull warm tight punchy sound.

So instead of selling it right away, I am currently doing the DAC route. I just brought a Audioquest Dragonfly Red and a Clarion EQS 755. I am pretty confident this will make the difference and that it will be at least as good as a Normal pionner or kenwood head units.

I will install it today , will keep you updated.

And then we will see what we can do with the rest of this Head units.

Have a good day everyone !

Iv just realised that the HU isnt saving my station presets. I know its a wiring issue. I believe I need to swap the red + yellow wires around. Does anyone have a pic of the wires that need to be swapped? Thanks
[MTCD Android Head Units General] RogerClark:
When you turn off your ignition, if the unit does not stay on for about 1 sec and then display a message for about 1 sec, saying its shutting down... You have wired it wrong.

I think the wire that goes through the inline fuse is the one which goes to Accessory power , which is only on when you have the key in the ignition turned at least one click (assuming you have a old style ignition key)
[MTCD Android Head Units General] kPATm:
It does do that. I swapped red and yellow over to test and it completely restarts when turned back on so the way I had it seems correct. Its just not saving stations?
[MTCD Android Head Units General] TrevSP:
OK , Installation is done ---

I can say that it does the job. Total investment is at 275 $ US dollar plus installation just to have a good sound quality.

And for the bluetooth and all the rest that cannot be route in the DAC for now , I simply put an RCA cable from the head unit to the Clarion EQS 755 , And at the press of a button on the EQS i can switch from the dac to the Head unit as my main source.

Hope this will help !!

Have a good day everyone.

Install JetAudio Pro player. It has a heap of custom sound settings. Here it is on Google Play, and of course the full version costs money. Oh, and your head unit plays FLAC, so if you're trying to get the best sound don't use low quality MP3's that are anything but 48000Hz 320kbps VBR tracks.

[MTCD Android Head Units General] TrevSP:
Second update.

Thanks DJSHOOTY for the update on your side , i will investigate the Program your sharing. But the Sound quality is just not enough on the head unit to keep it. Now i got another problem. The USB DAC is pooping crackling when I use the device at the same time that I am listening to music. I will have to investigate on that too because it is anoying !

The sound is great now at least !

have a good day everyone.
[MTCD Android Head Units General] djshotty:
How can you possibly claim to know anything about sound quality when

(a) digital to analogue converters don't cause "pooping" or "crackling",

(b) you don't understand that the best way to use the unit is to copy FLAC files from a USB drive into the unit's internal storage NAND and configure the third party music player you install to play those files from the NAND,

and

(c) you not only haven't read my Signature, you can't even spell my name right?
[MTCD Android Head Units General] TrevSP:
Ok ill check this tomorrow! But the Crackling pooping is really happening and its only when I am browsing from the head units and Utilizing my USB DAC. Maybe my Head Unit is Defective.

And right now I am using USB AUDIO PLAYER PRO from EXTREAM SOFTWARE DEVELOPMENT , as recommended by AUDIOQUEST

Sorry About your name, DJ HOTTY ;)

have a good day !
[MTCD Android Head Units General] djshotty:
Add an inability to both read and comprehend the English language to your list of flaws, because you obviously took no notice whatsoever of the comment in my previous post...

Get some music tracks that are in FLAC format, copy them to the unit's internal storage, disconnect the USB flash drive from the unit, install from Google Play Store a much better player than what you're using - preferably VLC Player, MX Player Pro or JetAudio because they're the top three - and play those FLAC files directly from the unit.

Um, no you're not.
[MTCD Android Head Units General] TrevSP:
I will send a video , you will see what i am talking about !

ON it for tomorrow !

have a good day :)
[MTCD Android Head Units General] djshotty:
A digital to analogue converter does not, I repeat DOES NOT cause crackling or "pooping" (the word is 'POPPING') sounds to be heard over the top of music. There is either an electrical issue with how you have installed the unit, or the music files you're using are of poor quality. Please accept my advice as correct, seeming though I've not only been installing car entertainment systems for over twenty five years, but been a nightclub deejay since 1987 and know more about music quality than you know about any subject!
[MTCD Android Head Units General] skezza:
What about if there is a driver bug? A buffer underflow? That would cause it. Not saying it's that, in fact it's almost 100% unlikely but just saying. Play devils advocate.
[MTCD Android Head Units General] djshotty:
You're right about those explanations you've given being, as you put it, "100% unlikely", which is why I posted the information that I have in an attempt to satisfy a member's call for help. What I'd like to know is, when one single member with just a small handful of posts declares he or she has an issue with a product, then another member responds with the correct solution, why is it that the respondent gets lambasted and critiqued? I myself have not experienced the issue which TrevSP has described, but only because

(a) I installed the unit into my vehicle as per manufacturer's directives,

(b) I play only the very highest quality copy of each music track I like,

(c) I use only the latest and best Android music player app. available, and

(d) the rest of the hardware installed in my vehicle (speakers, amplifier, wiring etc.) have been re-checked so as to provide an ideal and problem free listening experience.

In closing, if TrevSP doesn't want to follow my advice, then I wish him the best of luck in finding a solution to his "pooping" problem.
[MTCD Android Head Units General] TrevSP:
I am sorry that you have encountered a lot of bad people. But I am following trying to follow your advice. I download VLC and JETSTREAM and I found that JETSTREAM is a good player but I cannot find a way to send the signal to my USB DAC.

After some testing, I found the quality of the units better ( because I pass through the CLARION EQ and it got 8V output to get a Stronger and louder signal ) but still lacking in sound quality compare when the sound is processed by the Audioquest DragonFly Red.

Like I say , I have invested around 1000$ US ( A PAIR OF BLAM AUDIO 165.100 ( no rear speaker ) with a AUDISON PRIMA APBX 10 DS and a KENWOOD EXCELLON X801-5 ) in gear , install at a professional shop. ( I put 2 layer of Noico 80 mil 36 sqft car Sound deadening and a 10mm Heat Shield Thermal Sound Insulation in the front doors ) planning to install in on the first third of the floor in the van too.

For the kind of distortion in the DAC output that i can hear when i am Browsing in the unit. I am still trying to figure it out and I will find the problem.

I may be new here , but I am not that average joe :P

EDIT ,

I just Create 4 video we can access them here : https://drive.google.com/open?id=1LEBDARV6GRV_wF3pInB1fgjwm4Aw8Gbf

Clic while moving: is showing the pooping, but not all of it, sometimes I have other special artifacts

Head unit no clipping is showing us that it is ok with the head unit only, start at 1:15.

Head unit vs DAC show the improvement in Sound quality with the DAC - It is less audible on my phone but the BASS and Clarity is just better and the sound can go a lot Louder.

LAVALIER HEAD UNIT VS DAC: HEAD UNIT FIRST at 1:54 its the DAC, The lavalier mic pick up too much bass so we get distortions. ( I am going to try to get a better video ) ENJOY

I just add 4 more videos, 2 with my phone mic and 2 with the lavalier but with no sub. Its hard to pick up the sound on my phone, and the volume was so much louder when I listen to it ( almost blow my ears ) :)

hope this will help

I am doing all this to be able to really judge what is the best way to get the Highest sound Quality in a car audio system for an affordable price.

( i will change DAC for a better one in the FUTURE to test DSD and Sound quality )

The big point to get now, How to remove the poping and How can I get the DAC to work under other VIDEO and AUDIO APPLICATION.

thanks in advance.

EDIT : POPPING PROBLEM is hardware related , i am pretty sure now , I was able to recreate it while uploading stuff from a USB stick to the INTERNAL DRIVE.

I send a message to the place I brought the Unit to see what they have to say about that.

have a good day!
[MTCD Android Head Units General] djshotty:
In all seriousness, if you haven't simply plugged into the rear of the unit the harness of female RCA plugs, then connected your amplifier to that harness, then the amp to the speakers, you've installed everything the wrong way. Why you're using an external digital-to-analog converter is beyond my reasoning, as you're only adding into your audio's electrical path between the player and the speakers something it does not need.

Unless you're an audiophile, simplicity is often the best solution, instead of throwing a heap of money at something you don't understand.

Wow! If that's not a clear cut case of More Dollars Than Sense, I'm yet to see one!

Connect the unit directly to the amp, and do all your soundfield processing in the unit. Use at least 48000Hz 24bit 2channel stereo FLAC files to test, and decent music from groups like The Eagles, Fleetwood Mac, Genesis, artists like Peter Gabriel, Howard Jones and Sting who put the engineering of what they record in studio at the top of their priority list. You'll find that if you tune your soundfield using music from those artists, instead of pumping out rap crap subwoofer R&B nonsense that's been engineered by mindless simpletons sitting in a fog of crack smoke, it won't matter what genre of music you like it will sound great to your ears.

Well it sure seems that you are an "Average Joe", considering your posts above have proven that you're too incompetent to recognise

(a) the thoroughly useless and unnecessary "USB DAC" hardware component you've installed is causing the issues you're having,

(b) troubleshooting is a series of moves where removal of components piece by piece often uncovers the problem,

(c) sound reproduction is an art form best left to those who believe only the highest quality component at every point will suffice,

(d) the sound you hear is directly relative to the quality of the source of that sound, and

(e) my name is not anything else other than SHOTTY.

Oh, and for the last time, it's

P-O-P-P-I-N-G​

and NOT, as you keep on incorrectly claiming it to be, "POOPING"!!!
[MTCD Android Head Units General] TrevSP:
After I read your reply , I know you know a lot but Can we have more detail instructions , I am trying to figure out a way to have a better Sound quality because the HEAD UNIT with RCA Plug into it just cannot deliver it, And yes Those files I put in the videos are FLAC.

( I did everything you ask ) and still it's not as good as the DAC in Sound quality and DECIBEL ! the unit is just not at that level yet ( i want at least like a pioneer or Kenwood head unit sound representation )

My goal now is to get the DAC running like a champ on this head unit. Do you have any experience on how to make this happen? Like how I can get the USB DAC running under the 3 programs you refer to me?

Thanks for your help and I hope you have a great day. And Do not forget to smile
[MTCD Android Head Units General] djshotty:
Again, you're trying to put into the soundscape a piece of equipment that is simply NOT NECESSARY! If you have a top quality FLAC piece of music, speakers from brands such as Alpine or Clarion, a good 4 channel amp from Rockford Fosgate or JL Audio and a monoblock (for a minimum 12 inch subwoofer) from a brand like Fusion or Kicker, your head unit and a player like JetAudio has more than enough capability to produce awesome sound if it's installed correctly. Please take it from me and get this into your thick head: you DO NOT NEED your USB DAC, so throw the bloody thing into the garbage bin. Surely by now you realise that IT is the problem in the system?

Go through the settings of the unit thoroughly, and tweak them in different ways to get the sound you want. The standard equalizer app. has got a LOUDNESS switch that I bet you didn't know about. Next, take a look inside the unit's Factory Settings section, where there's tweaks for the inbuilt amp which add a bit more power to the output. Also, in JetAudio Pro there's a veritable smorgasbord of audio enhancers (such as DFX HD) which make your stupid USB DAC box completely worthless and totally obsolete. Then it's a simple case of setting the unit's volume to around 14, and moving onto the 4ch amp to tweak what it sends to the speakers. Lastly, play around with the low frequency settings on the monoblock to get the subwoofer sounding sweet.

Please do not bother me further for advice, because if you can't get a decent sound from your system after all that, then you're best off pouring a drum of petrol into the cabin of your car and and burning it to the ground.
[MTCD Android Head Units General] TrevSP:
ok thanks Shotty for all your advice. I am going to USE them all to see if it sound better than the DAC or a Stock AMERICAN brand HEAD UNIT.

About the Gear, I try it at the store and I like the sound of the BLAM more than FOCAL and HERTZ.

What matter is the Clearness and punchiness of the system

My FLAC are from CD that I personally convert with the best program available.

EDIT

After Having a Private Message from Mister Shotty, I remove all post or line that want to have a more detail opinion.

Sorry for your time and have a good journey.

------------

So now lets go with people that actually want to have the best sound quality possible with any Unit available on the market.

After I try using multiple settings in my head units, My DAC Still sounds better. I am using with he head unit the jet audio plus pro ( paid version ) with the onboard EQ,the 30 day demo of the Special EQ that goes with the speaker you have( can't remember the name ) , Head unit at 15 volume, my AMP volume crank up and my preamp volume crank up to help.

I will do more investigation into this and I will post all my advancement to help other people on this subject matter.

And If someone already has Knowledge about external DAC, I will be happy to hear from you!

EDIT

After a lot of tuning, I prefer by far the sound that is coming out of the DAC !

So I will put all my time and effort into this now !

Will keep you guys in touch with people that are willing to go that route !

EDIT 15 August 2018

I put an amazon basic usb 2.0 hub ( AmazonBasics 4-Port USB 2.0 Ultra-Mini Hub ) on the line and the POPPING problem is now gone! I am so happy! Still we got a little fuzzy sound that I need to figure out where it comes from.

I will buy an AudioQuest Jitterbug too to see if the sound is better with it too

All I can say, If you have the 300 to 600 $ to put in ( depending on what DAC your getting ) It definitely worth it!

have a good day everyone !
[MTCD Android Head Units General] TrevSP:
Another problem ,

I just brought a 128 gig SD card and When I put it in the head Unit ,I can see that their is something in from the top of the unit but It will not show in the file management.

Is their something we have to do first ?

My card

SanDisk Ultra 128GB microSDXC UHS-I Card with Adapter(SDSQUAR-128G-GN6MA)

I try to format it to NTFS and it did not work.

I retry the NTFS format but this time with 8192 bytes selected.

I put 1 video in it and I open good map too.

It works !
[MTCD Android Head Units General] djshotty:
Ah well, stupid is as stupid does...
[MTCD Android Head Units General] TrevSP:
You are a funny man Shotty !

Have a good day every one !

:cool::angel:
[MTCD Android Head Units General] Flemischguy:
You have to format with FAT32!

And check if your unit is capable to cope 128gb micro sd card otherwise you got to use 64 gb micro sd card
[MTCD Android Head Units General] velocity4:
I have successfully used fat32format (https://en.softonic.com/download/fat32-format/windows) program to format 256GB SD cards (and large hard drives too) in all my units. No problems even if they say they only support 32GB cards.

Try it its great:)

It's better, but I'm having issues with call waiting. People are getting busy signal while connected to Bluetooth.

If you can double check that you get call waiting while on a call.

I'm trying to narrow down the problem.

Video through video outputs

Has anyone been able to get this unit to play video through output one or two? I'm trying to play USB videos, or mirror the screen to my rear DVD player. It would be great to play Plex/Netflix/Hulu in the back for the kiddos.
[MTCD Android Head Units General] Rhoobarb2005:
Can anyone confirm the screen brightness levels are significantly improved from the older gen MTCB units? I currently have a generic 1GB/16GB RK3188 HU installed at the moment, which is very hard to see, even on an overcast day. If it is bright sunshine you can forget it. I really need something that will be comfortably visible in daylight.

If not this one, perhaps someone can recommend a 4GB/32GB 7"+ Octacore unit that is nice and bright?
[MTCD Android Head Units General] jamies22:
To me it appears your the one that cant comprehend

What he is trying to say is the internal DAC and audio circuitry sounds **** ( and it most likely does being a chinese head unit) it likely lacks dynamic range, clarity etc

and that when he uses an external DAC it sounds much better (ie like a higher end head unit)

yet you refuse to accept this and spin **** about no need for external dac, use flac audio etc. perhaps you need to take the time to comprehend better, and also accept that there may be some language barriers with people from all parts of the world
[MTCD Android Head Units General] djshotty:
When there's a veritable smorgasbord of sound-altering plugins for many of the better music playing apps, there's no need for an external digital to analog converter, simply because that external device is doing the same task twice, which is why the guy's having issues.

His external DAC might just sound better to HIS ears, and may have worked well in his other system which had need for one, but to an experienced audio technician most likely the setup he's running would sound awful.

When the simplest methods of sound reproduction have, over the last thirty five years I've been in the music industry proven to give the best results, I beg to differ. All I tried to do was help someone who clearly showed by both his original post and responses to my suggestions that he has close to zero knowledge about sound reproduction, simply by his insistence on connecting to his system an item which in all seriousness has no place in the scheme of things. Here endeth the lesson...

Finally pulled the trigger and bought this. I'm putting it in a Jeep Liberty (Cherokee in the non-US world), so I bought Metra 95-6524B Double DIN Dash Kit. As others have noted, this radio is just slightly larger than this opening, so I have to figure out exactly what to dremel off. Fortunately for me, with this trim kit, the HU itself is mounted directly in the vehicle, and the trim is just that; trim. It doesn't hold the radio in place at all. So today's project - Trim the bezel :)

I'd also be interested in comments regarding screen brightness. I have a drop top and my current unit is not hardly visible at all during the day.
