If your HU doesn't kick over to the view(even empty) then you could just use the reverse wire from your harness to you reverse switch on the car harness. Usually this is part of the wiring diagram, but it's usually the green wire.

If the HU is kicking over but you have no video then yes you probably need to send a signal to your mirror OR you have the wrong RCA jack
[FYT Android Head Units] xdamember2:
If connected to av plug you should see rear view when run the Aux app. There may be another yellow jack or it may be hardwired to the harness. Check the connector diagram.

Recall on my old Intel Sophia HU, there was a setting with regards to speed volume compensation - basically volume increasing automatically based on speed.

On the JY-UQD10N4G-R, I cannot for the life of me find any such setting. I want the volume to remain consistent, regardless of speed. The problem is when I have the volume set to say 7 and my speed reaches 60ish, the volume increases substantially, almost like it's at 20.

Any help is appreciated.
[FYT Android Head Units] xdamember2:
On mine it's settings - device - sound - speed compensated volume.

I have a 10 inch model of the uis based unit. How is optical implementation done, is it via dac or coming from adc. I will have to open up mine to check which is already installed. Just wanted to check . Also can anyone tell if they are planning to put in usb drivers so that we can use a usb dac
[FYT Android Head Units] xdamember2:
I have not tried rooting, I have however played with modifying the update package and I think that would be the way to go.

hi guys, the firmware for July 5th has been released.

[FYT Android Head Units] Blaze Falconburger:
Hi all, I am thinking of purchasing one of these units (https://www.joyingauto.com/joying-9...-android-10-0-car-autoradio-ips-1280x720.html or https://www.joyingauto.com/joying-10-5-inch-bmw-e46-android-10-0-car-radio-ips-1280x720.html) to replace my old sofia unit in my old E46. Which worked well, albeit very slowly now, and with some quirks, and I just wondered:

- Does Viper audio work with this unit? Is root needed?

- Is there still a bluetooth bug with syncing contacts? I remember it would randomly delete all my google contacts before which was highly annoying

- Is sound quality the same or any improvement over the sofia FYT5009 units?

- Are there any custom roms for this unit, or are there likely to be? I am out of touch with the MTCx units for the last few years

- Does music properly pause/resume on power off - this is something that really bugged me on the previous unit as I couldn't get it work properly - it would keep restarting at the beginning of an mp3, making it difficult to listen to long tracks, such as audio books.

I mostly use it for stored mp3s on an ssd drive via USB, playing via foobar and streaming - Spotify/soundcloud and Google Maps via mobile tethering

Joying have offered me a 5% discount for a repeat customer, always worth asking..

Thanks all

I'd suggest if wanting carplay or Android auto, these Chinese knock offs are not for you. They're not certified as or cp, they are after all a modified Android with a screen mirroring app that is known for bugs.

its not important for me, but since they have everything in place already it would be a plus to have it. I know they arent certified either.

[FYT Android Head Units] techy101:
Wow, I'm surprised that any shipping happened over the holiday. Chinese New Year is the most difficult from a logistics standpoint; the whole country gets 7 days off and some get more. Working at an electronics manufacturer we have to plan around it. Do you know if it's coming DHL or FedEx? Both are fast once it leaves the country.
[FYT Android Head Units] :
It was picked up on the 29th so i guess right before they went on holiday
[FYT Android Head Units] ArmchairA:
Anyway to resize the screen on these newer Joying units? I'm ordering the JY-HQS01N4G-1 (which is one of their newer Android 10/ARM units), but the left/ride sides of the visible screen are slightly larger than the opening in my car's dash (and it's pretty much the only Android head unit that will get very close to fitting due to the odd opening size on my car).

If rooting is the only option to do this; how long until we think these are rootable?

Thanks all for the info provided so far.
[FYT Android Head Units] techy101:
I got curious and *tried* to take some measurements of the differences between the OEM system in my 2009 BMW 335i Coupe (E92). It's been a while since I've done this but it's at least something. The OEM head unit and Joying head unit look surprisingly similar when both are set to flat outputs, though there is an audible improvement with the Joying one. The big changes came when I enabled time correction. I only used the default settings so I imagine this could be improved significantly with more accurate settings, however it's still in a car and will never be good.

The measurements were taken with the windows up using Rational Acoustics SMAART V8 with a simple (aka low end) Behringer EMC8000 measurement microphone (these have a linear frequency response) running through a Focusrite 18i20 Gen 2 audio interface.

The biggest difference I saw was, unsurprisingly, the time correction results. There was a significant phase improvement, especially in the 125Hz to 1kHz range, with a noticeable reduction in the comb filtering.

It isn't all that telling, but I thought it was still neat to see. If I have time I may also measure the optical and/or SPDIF outputs to see how much the head unit messes with the audio and how much propagation delay there is in the system. I'm also interested in seeing if I can catch the slight hiss that these units put out when they're not muted.

Please, could I asjk you to make pictures of the bestycar Head Unit you picked up? Rear connectors of the HU, harnesses...

And maybe you can write some info on how their Interface is, thigs that work well, things that doesent... If the HU has bugs and alike?

By the way - did you picked the HDMI option (as the 1-DIN unit might look different from the 2-DIN flat version )

I've also found them for my car, but their shop is relatevely new... so any feedback would be great. :)

[FYT Android Head Units] r.onic:
Great - exactly the configuration i'm looking for. If it's a "longer" HU - better cooling might be provided with an additional fan (I've seen ways to mount on 3D print frame ;))

the store was actually unable to write if this HDMI port ist actually an OUT only or can be used as Input :)))

So your report would be very helpfiul ;)

Anyone know what 4G LTE GSM bands the Joying 11" headunits have (running Android 10)

And do you all feel this is the best android headunit to buy compared to the others?
[FYT Android Head Units] sdugoten:
It seems I am having issue on a UIS7862 headunit with bluetooth. Whenever I use my iphone 12 Pro max connect to the headunit via bluetooth, from time to time Youtube will randomly skip to next/previous track. It doesn't happen all the time, but it is very annoying. Moreover, I found that it not only affects Youtube, any music or video player in IOS would have the same random behavior.

I was trying to get into the developer options to change the AVRCP version to something lower and see if that would help, and then I found out I don't have the password to get into the developer options.

Does anyone got that password or experience the same issue and got a fix? Thanks.

What I wish to know if new joying 11" Headunit is best Chinese Android based headunit available currently?
[FYT Android Head Units] gottahavit:
No one here can tell you if it's "the best". Joying is one of the more "reputable" distributors, but it is going to depend a lot on your car, how you plan to connect it, and which Joying model you are looking at. I have both a Joying and an IDoing(Sam FYT base system), but the "best" for my WRX was the IDoing as they offered a Canbus that worked with my factory HK audio system. The Joying was "the best" for my corvette because it has the form factor and features I wanted as well as digital out for future expansion.

This is excellent info. Thank you for sharing.

I just purchased joying 6GB ram / 128GB storage 11.2" screen head unit for my 2018 Jeep Wrangler.

On their website they claim:

-1080x1920

-5.0 Bluetooth

-PnP harness for the vehicle

-Built in GPS

I hope it's all true.
[FYT Android Head Units] Bob_Sanders:
I depends on what you think "best" is. One of the first things I do with a head unit is turn it around and look at the back side because that will tell you what the machine is all about and what it can do. Machines with a lot of input/output ability are what I tend to go for.

While other machines tend to rely on the more universal USB connection (and there are only 3 on most of these machines), Dasaita on top of the 3 usb connects, it also has

separate

inputs for:

TV

Rear cam

Front cam

Video record (dash cam)

TPMS

Secondary HDMI screen output

Separate card slot

And it also has not one, but TWO sub outputs.

I believe Dasaita also comes with more software loaded... TV app, Dash cam app, TPMS app... etc

Anyway... you can connect all of these things and STILL have 3 empty usb slots to work with. That's worth a fair bit in my book.

Now Dasaita does not have the digital output, but I have read that the digital output is a bit restrictive in its bandwidth so it's not really worth it anyway.
[FYT Android Head Units] CCJ22:
@Bob_Sanders it's so good to see you on here. I am the guy that invited you to Jscan facebook group.

I read the Joying unit I bought (11.6" screen seen HERE ) locks down the Bluetooth which is a shame for you and I since we use Jscan. Does Dasaita also lock the bluetooth down? Is there a way to unlock bluetooth on the 11.6" Joying?

I decided on the Joying because it has a bigger screen and looks like it has true 1080p HD as well. I also notice on the Dasaita website they have no more products for Jeep / Chrysler vehicles. Which was off putting.

@warata @RealZac

hi, I did succeed enabling dark theme in google maps. you need to set your screen DPI lower (like a phone DPI instead of a tablet DPI) before opening google maps, this way you'll trigger google maps "Theme" feature in its settings. After that, you can revert back to the default tablet DPI.

To change the screen DPI, go to developer options (enter password, I think "3368")

Scroll down until you find "Smallest width", change it to 411 dp.

Then open google maps, and you'll get the "Themes" feature

[[ Memorize the default DPI to revert back later ]]

if you want to enable "System-wide dark theme" on whole android 10. you need ADB & usb cable. I used this app "

Automatic Dark Theme for Android 10" from playstore​

Well, I'm not sure about Joying but Dasaita does allow me to run the icar vagate elm327 adapter so I do run jscan on the Dasaita without too much issue... although it is a pain in the azz sometimes to get the bluetooth to cooperate.

I would be very surprised if the Joying doesn't let you!?!

I would love it if jscan would make their app usb compatible. I have torque pro on the Dasaita too but I have it connected through usb (OBDLink SX USB) and it is supper fast... MUCH faster than the bluetooth elm327... and much more dependable a connection too.

Torque Pro through usb:

You will have to post a "Jeeper's review" on that Joying when you get it installed!

I just picked up this head unit. So much potential...so many flaws.

The primary problem I’m having is with the implementation of CarPlay. Does anyone know of a method to disable wireless CarPlay? I’m having a lot of issues with flakey audio streaming when connected via WiFi, which aren’t present when connected via USB. The stereo establishes a wireless session immediately, and even if I plug in, the connection remains wireless unless I turn off WiFi. I always plug in anyway, to charge my battery, so wireless CarPlay that’s flakey is a burden.

Second, is there any way to get an app like Spotify to resume what was playing in the last CarPlay session? It’s super annoying that no audio ever starts when I get in the car.

Anyone else have these same issues?
[FYT Android Head Units] CCJ22:
Agreed on all counts!
[FYT Android Head Units] warata:
Hello guys, I would like to use this Read It on the 7682, but currently it is not available because the assistant cannot read the screen. I think this function is very convenient because we can't read characters while driving. Please let me know if you have any ideas for making this feature work.
[FYT Android Head Units] RealZac:
That doesn't work for me. Set dpi to 411 - no theme settings in GMaps. I even tried 400.

But: I set dpi to 480 (instead of 600) and the launcher and Sygic, even Spotify are looking good. Think I'll test this a few days.

Update:

After I changed to 480 dpi, the GMaps theme settings appeared. I changed to dark and switched back to 600 dpi. 480 was too "big". ;)

Thank you, @vipsms

So after contacting Joying for help with this and exchanging a lot of emails with them, they finally told me to swap the power and acc wire as some cars have them the other way around...

After swapping the wires around the head unit boots instantly after turning the key! So sleep mode wasn't working for me before because the unit would do a full boot each time it turned the key.

Finally solved the problem, I hope this helps if anyone else has the problem I had 😉
[FYT Android Head Units] CCJ22:
Will you please tell your contact at Joying that many of us would like to see the following changes on next iteration. We are happy to pay more money for these features:

-High definition LED screen w/ 500 or more nits of brightness

-Matte screen because the reflection is horrible on this unit they currently sell

-A true amp turn on lead from back of headunit. Currently, amp is always on even if we are just using screen and not using speakers.

-Please remove the chrome trim around the headunit. It does nothing but blind driver during certain times of the day

-The bluetooth sync is deleting all google contacts from peoples phones, been doing this since 2019 and they still haven't fixed it.

Thank you for reviewing these units for us. We do wonder if they send you a great unit then water down units to the rest of us.

My unit I got today has dust in the screen. I sent photo and video to joying. They replied back telling me to open the panel from the side screws and clean it myself. I thought that was laughable. While I'm at it, I might as well paint the trim cause the chrome is HORRIBLE in my Jeep wrangler during certain angles it will blind the driver.

Video may be seen here
[FYT Android Head Units] Bob_Sanders:
That kind of sucks.

It shouldn't be too hard to open up though.

I remember when my Dasaita arrived..... shipping damage... the 720p screen was cracked. They sent me a new screen but I had to install myself. No big deal... I enjoy doing that kind of crap but you really don't plan on having to do your own warranty repairs... and it kind of takes you by surprise the first time around.

[FYT Android Head Units] piyush7243:
It doesnt work. they dont have a usb audio driver
[FYT Android Head Units] Allan_Hun:
USB audio player pro does not need any driver. Attached photo shows my 7862 streaming 88khz bit perfect mqa audio to my usb connected DSP.
[FYT Android Head Units] piyush7243:
Are you sure it's the same model as this thread. My usb dac don't get detected in the headunit and I have tried many. Any different you are doing?
[FYT Android Head Units] Allan_Hun:
I think there is an option in factory setting to swap the power wires.
[FYT Android Head Units] Allan_Hun:
My unit is branded as mekede, but it's same hardware, same software and same bugs.

You wrote that you have tried many. Many DACs, many Head units, many apps or many settings?

I'm sure some usb DACs will work on your joying with USB audio player pro -but I'm not sure any usb DAC will work.

USB audio player pro is a brilliant app used by many headfi enthusiasts. But it does have some limitations: It will only play local files, network folders, tidal and Qubuz. So it won't play FM radio, BT and such. And software volume control does not work in bit perfect mode. But software volume control also degrades soundquality, so hardware volume control is superior.

Lucky my DSP automatically switch between RCA, optical and usb sources. I also have remote volume control so I use usb when I want optimal sound quality (tidal hifi) and optical for anything else.
[FYT Android Head Units] piyush7243:
Thanks a lot for the response. I have 2 headunit 1 Joying nad 2nd one I don't know the make. From the sound of it u have a Helix dsp pro or above. I have tried quite a lot of dac I have. Also I have been using usb audio player Pro for many years now. Not sure why it doesn't work in both. Can you send me a screenshot of usb settings under developer options. Also does dac works on all usb ports?
[FYT Android Head Units] Allan_Hun:
I'm using helix mini DSP (Brilliant device worth every penny!) with URC.3 controll unit and HEC USB input extension module.

Works fine in usb high speed mode without changing any settings.

I don't know if all 3 usb ports works for this, but USB initializing was a little unstable when I also had my OBD reader connected through usb. I don't use my OBD reader much so I just routed one usb port to a USB port flush mounted in my console -so I can easily plug my OBD reader in if I need to.

Searched around and cannot find any answers. Bought this unit and I am very pleased with it. However, I cannot get apps such as Youtube TV and ESPN to stream. Netflix and Youtube work fine.
