Any new feedback about these units? For example:

1. How is the in call quality?

2. What about boot time comapred to the lder gen?

3. Are these confirmed FYT?
[FYT Android Head Units] Matt Devo:
Mekede M7Plus - UIS7870

1) untested

2) faster by about 5s? it's noticeable. reverse switching faster too

3) yes, get GetInfo tool reports a bunch of FYT params. And I've already started to tweak mine (bootsplash, animation, config file)
[FYT Android Head Units] tids2k:
1. Can the USB C port on the back of the headunit support external displays. This would allow bigger screens to be attached to the headunit without modifying the display drivers or firmware on the device.

2. What was recieved in the packaging ? Were the 360° cameras included. Is the 360° chip built in ?

3. Which previous device was used to compare the percormance with 5sec improvement ?
[FYT Android Head Units] j0hn83:
The question was asked based on the previous generation, which is the Mekede M6 Pro.
[FYT Android Head Units] Matt Devo:
1) no idea. I don't have a small portable USB-C monitor to test with

2) I bought the HU itself bare, so it only included the non-vehicle specific wiring. 360 cameras and hardware support are still a separate option AFAICT

3) M6Pro w/UIS7862s, running the latest kernel (20231205) and AllAppUpdate.bin (20231009)

the boot time improvement was so noticable that I had to modify my bootanimaton to hold on the last frame for a half second or so just to be able to see the end, whereas on the M6 it would hold for a few seconds while the device finished booting.

one annoyance on the M7 vs M6ProPlus is that there is no bottom navbar with volume controls, and if you add it back in via config.txt it screws up the sizing and layout of all the FYT apps (including the launcher, radio, etc). I'm not sure how you're supposed to adjust the volume from the unit itself. using the slider in the notification tray is not a viable option when driving

To all my "Chinese/Asian " friends, give me your thoughts on this one :

I tried to purchase it on taobao but have been told that they cannot ship overseas. Is there any other way to ship it outside China, the device looks very promising.

https://item.taobao.com/item.htm?id=654252946462&spm=a21m98.27004841
[FYT Android Head Units] W.West:
You may consider using a freight forwarder that has a warehouse in China and ships to your country, if you want to try it.

As for the device, what I know is that its operating system is called Dudu OS. There is a beta channel for fyt 7862 users and it seems to have a good reputation. However, since it's for Chinese domestic use, some services won't be supported. I heard that there would be an international version later. Also, the motherboard for that device is l888(the high-end model, and Dudu OS won't be supported on l880(the one currently being sold widely).
[FYT Android Head Units] tids2k:
" Also, the motherboard is l888(the high-end model, and l880(the one currently being sold widely) won't be supported. " - sorry could you please elaborate. Are you saying the one listed above is with the I888 motherboard ? And what we will recieve once available will be with I880 motherboard.
[FYT Android Head Units] W.West:
There are two motherboards for 7870, which are YL880 and YL888. Basically, there are differences on the parts used.

For 880 model, it uses AKM7738 for DSP, TDA7851 for amp, RTL8761BTV for bluetooth, and 6,800uF capacitor

For 888 model, it uses AKM7739 for DSP, TDA7803 for amp, Qualcomm 3031 chip for bluetooth, and 10,000uF capacitor

I think it can be seen as similar to the difference between a regular 7862 device and the M6 series.
[FYT Android Head Units] tids2k:
For the DUDU OS, if you have a Mekede M6 Pro FYT YL850/YL860.

Test version for Dudu OS Link :

https://disk.yandex.ru/d/PIFOK3SXOxwiWQ
[FYT Android Head Units] W.West:
From what I heard, yes, it's l888. Also, other users asked the developer about the availablity of DUDU OS on l880 and he said there are no plans for it.
[FYT Android Head Units] W.West:
Looks like Mekede updated the M7. Looking at the differences from what I have, the logo and product name have been added to the back plate, the Mekede boot animation has been applied, and the menu button on the top bar appears to have been changed to the same one found on the M6.
[FYT Android Head Units] tids2k:
Yes, I had a play around with the Launcher yesterday both the International (Global ) and the Chinese version. It appears the navigation functions are fixed for eg. for Chinese version you only use AMAP and most of the functions might not work as there is no support for external maps ( for eg. it would show my location map in Australia with street names and actual drawing of the streets are restricted or incomplete.

Then again with both the versions it seems that you need a WeChat/QQ account. For now it would let you register as a user with an external email however the inbuilt activites require a WeChat or a QQ account. Overall this is a great launcher and regular updates on Telegram Channel , the development is on par. I hope the development will be later picked by our devs on XDA.
[FYT Android Head Units] W.West:
Yes, even though Dudu OS won't be supported on l880, I hope to see the dudu launcher supported on 7870. The current Mekede launcher is generally good, too. But we want better of them, don't we?
[FYT Android Head Units] laoyang88:
TDA7803(y)(y)(y)digital input for direct connection to I2S(y)(y)(y)(y)
[FYT Android Head Units] W.West:
I honestly like the external mic input on the back. It's a shame that it's only in the 888 model.

By the way, the latest system file date is 2023-12-20. It was included in the IYING firmware I recently got.
[FYT Android Head Units] tids2k:
So even IYing is using Dudu OS then ? Could you post the link if allowed for the system file ?

I would assume as all other Chinese.OS updated there would be two separate firmware for the MCU flash and the system data file. Future development would help in creating a frankestien build with the I888 MCU and global rom firmware.
[FYT Android Head Units] W.West:
No, I was just expressing my own thoughts about the backplate and talked about what the latest system date was. IYING does not use Dudu OS, but the general firmware with its own launcher. Sorry to make you misunderstand.
[FYT Android Head Units] lowridincrew,:
It's a big discount on one of the 7870 Units bringing it to below $250 for me. I'm debating on grabbing it but it's so new, I'm kinda scared. I'll be throwing it into my project car if I do.
[FYT Android Head Units] anginx:
Hello guys,

I’m trying to make up my mind between the Mekede M7 plus and the IYING that was shared in this thread.

I can close an order for the M7 plus, I ordered on Aliexepress for around 250 euros.

My dilemma is between buying a less recognized brand like IYING vs Mekede, plus the seller from LEROAADZ is kind of pushy, the HU from LEROAADZ are out of stock and he wants me to extend the delivery for 1 month while Mekede HU can be delivered within 5-7 days.

Judging so far, communication is far better with Mekede.

What I cannot judge is the quality of the HUs in comparison, price wise LEROAADZ with discount plus shipping is way more cheaper.

What would you recommend?
[FYT Android Head Units] gordgelin:
since these devices are quite new you will probably have some questions so i'd stick to seller with better support
[FYT Android Head Units] anginx:
Kind of what I was thinking, I will cancel my order fro LEROAADZ and get the M7 Plus directly from Mekede.

Thanks @gordgelin.
[FYT Android Head Units] halloj:
Do you have a link to M7 plus. Can't find any link on Ali or Mekede. Thanks
[FYT Android Head Units] anginx:
No, you have to contact them directly.

If you look on Youtube the video promos in the comments section there is a representative from Mekede, he can put you in contact with the right person.
[FYT Android Head Units] j0hn83:
The M7 won't be on Ali for a while yet.

Direct contact and through resellers only currently.
[FYT Android Head Units] halloj:
Which reseller(s) for Mekede and M7 Plus right now? Any link to a reseller? Thanks.
[FYT Android Head Units] j0hn83:
I mean resellers who buy in bulk from Mekede and then sell to their own clients.

I don't know any online resellers who sell it.

I can only find the M7 online from 2 places. A Russian site that will ship to Russian addresses only, and if you contact Mekede direct and ask.
[FYT Android Head Units] halloj:
OK, thanks. I will then wait for the official release.
[FYT Android Head Units] anginx:
This is the video promo that I got the contact from @mekede-ceo.
[FYT Android Head Units] j0hn83:
To save anyone additional steps, they basically give you Mekede's official WhatsApp.

[FYT Android Head Units] lowridincrew,:
What was the price through Mekede?
[FYT Android Head Units] tids2k:
Whoever is wanting to buy the new devices, I would suggest you to wait and do not jump the gun. There are a lot of devices that I am seeing on TaoBao with 13" screen going for the $500-$600 AUD with Standard Accessories ( no Canbus or 3D Cameras ) . You should search and follow the Dudo OS on Telegram if you are interested in where the market will be heading and for different UI experience. Aliexpress they are all retailers for the 7870 devices. And not all the devices with other manufacturers with 7870 chip are currently listed. They will slowly bring the devices in the market as there is still a lot of 7862 & 7862S stock. Look or search for compaines like Caska, Lianshan. I will wait until the device from Lianshan is released for international market. They are the best selling brand that I can see in China and will be releasing the devices soon in coming months. https://m.intl.taobao.com/detail/de...3578523007.27.63081cecAVpVwQ&id=654252946462& not sure if the link would work but this listing is from TaoBao. Look at the videos and the photos posted in the review section.

There is a Youtube link for thier UI and have a look beats every other manufacturer device UI. Also they are a new brand and would make sure that the customer experience is on par with other devices.

DONT SETTLE FOR ANYTHING LESS THAN A 13 INCH SCREEN.

A listing on Aliexpress for 13 inch screen : https://www.aliexpress.com/item/1005006403826808.html . For AUD $648 plus free shipping.

If I was desperate and wanted to buy one right now. The above would be my ideal choice.

Also to be careful when purchasing the device is the comm outputs on the back of the head unit. For eg. Langshan has a USB 3 and a MIC IO connector at the back of the head unit, which is extremely handy as per the image posted above a few posts.
[FYT Android Head Units] gedster314:
I'm quite happy with a UIS8581 too but I haven't tried the other one and am very new to the scene. I would love a cell radio with more bands though.
[FYT Android Head Units] meremortal70:
Quite happy with the stability of our Google Pixel Phones thank you
[FYT Android Head Units] meremortal70:
Do you have separate power to the rear camera, if it only uses power from reversing light then the camera will only work when you select reverse.
[FYT Android Head Units] W.West:
I am using the genuine rear camera right now so there's no seperate power right now. To explain in more details about the problem, when changing gear to reverse, the rear view should be normally shown on the display according to the signal the system interpreted. When I enter the camera app that independently works manually in the reverse gear, the rear view is shown correctly, which means that the rear camera line works normally. However when I enable the option to show the rear view automatically, the rear view video becomes black at that time.
[FYT Android Head Units] halloj:
Thanks a lot for the information. Do you have a link for "Langshan"?
[FYT Android Head Units] tids2k:
If you are asking for 'overseas' model that can work outside China currently not available, The Chinese version link is in my post. The TaoBao link.
[FYT Android Head Units] tids2k:
You can ask @Yaoxl and @gordgelin for more info :)
[FYT Android Head Units] j0hn83:
You couldn't pay me to put a 13" screen in my car.

My fascia fits a 9"/9.5" screen and that's what I want.
[FYT Android Head Units] tids2k:
Haha. It depends. It is very aubjective.
[FYT Android Head Units] W.West:
New promotional image of Mekede M7 came out. I captured this from the youtube shorts video of the Mekede official channel.
[FYT Android Head Units] W.West:
There are some new firmwares.

1: https://drive.google.com/file/d/1ET81KFTNzoaotby8nMoP9ZtY2sLR-M9N/view?usp=drivesdk (Mekede)

2. https://drive.google.com/file/d/18nbXHZ3ceTlSYeJwbumIfJpwKuGHjN3n/view (IYING)

First one is Mekede, and second one is IYING.

I only tested the Mekede firmware, but it has a critical problem with enabling gboard from play store. I also tried Microsoft Swift keyboard, but the result was the same.
[FYT Android Head Units] W.West:
I tried the IYING one. The latest system date is 2024-01-06. The problem with keyboard enabling did not happen with this one.
[FYT Android Head Units] lowridincrew,:
Just ordered mines for LEROAADZ for $220.36 USD out the door shipped. I'll just have to keep up with the firmware which I don't mind.
[FYT Android Head Units] j0hn83:
I assume not all have these identical specs?

I see some YL880 models come with Qualcomm QCC 3083 Bluetooth chips.

Do the YL880 models have the issue with internal mic always being on?
[FYT Android Head Units] gordgelin:
yes L880 can have any of realtek or qualcomm. my l880 have qualcomm
[FYT Android Head Units] gordgelin:
7870 firmwares are not very stable yet so it will take some time to address all issues
[FYT Android Head Units] W.West:
Well, most of the 880 models I've come across are Mekede or Iying related, but the specs seem to vary depending on the seller.

As for the mic issue, switching between internal mic and external mic seemed to work well initially, but I haven't checked after I replaced the display which doesn't have the internal mic since I removed it.
[FYT Android Head Units] j0hn83:
It was IYING I was referring to.

All the Mekede units say Bluetooth 5.0 with realtek chip but all the IYING units I've seen all say Bluetooth 5.1 with QCC 3083
[FYT Android Head Units] j0hn83:
Thank you

On the previous generation the mic issue was a hardware problem was it not?

Can your internal mic be turned off?
[FYT Android Head Units] W.West:
I see what you mean. I saw the product image right now and saw that part. But the specification table still says 5.0 so maybe I only remebered that part.

Then again, the bluetooth type in the config works when I installed the IYING firmware on Mekede device. The type number was 0 in the firmware, and for Qualcomm chip, the number is probably 7 in the config. I tried that number and bluetooth wasn't working on mine which uses the Realtek chip.

Edit) I checked the other sellers. Like you said, they say Qualcomm chip with 5.1, but it looks like some of them use the image without modifying it with the correct information. I guess checking with the seller would be accurate.
[FYT Android Head Units] j0hn83:
It likely worked because Type 0 is the built in SoC Bluetooth and should work on any device (on the previous generation at least).

Realtek was type 1 and qualcomm type 7.
[FYT Android Head Units] W.West:
Yes, from what I experienced, looks like the type number also applies to 7870 like 7862.

I don't have a lot of information on the 7870 as opposed to the 7862, so I feel like I'm arbitrarily confirming what I know when sharing the experience of using it.
[FYT Android Head Units] tids2k:
Were you able to run Dudu Launcher on the device ?
[FYT Android Head Units] W.West:
I haven't tried it yet. I think I'll try after I install the next version of Mekede firmware.
[FYT Android Head Units] tids2k:
Mekede M7 Plus Review ( Russian ) use can use English Captions.
[FYT Android Head Units] tids2k:
Did the latest Iying firmware fixed this issue fo you ?
[FYT Android Head Units] W.West:
No, the problem still persist but I'm getting closer to the reason. I was using stock rear camera, and in addition to this, I installed front camera that I bought from Aliexpress.

I think the signal from front camera is somehow interfering with the rear camera signal when I enable the local radar option. With camera app, I can still see the rear view but I don't see the front view so this would be front camera problem. The problem persisted even with changing firmware so I think disconnecting front camera would be the best option.

I'm going back to the store that installed front camera to disconnect the front camera again and modify the external microphone this friday.
[FYT Android Head Units] W.West:
Mekede started providing firmware download link for M7 7870 from their site. (The lowest, rightmost one in the image)

https://www.mekede.com/SoftwareAddress1/
[FYT Android Head Units] j0hn83:
Cheers.

I had to clear my cache for the Mekede site as it was still showing me the old page with old dead links to the nutstore.

I just downloaded the M500s firmware and they are now faking it as Android 13 😂 Good old Mekede.
[FYT Android Head Units] marjanoos:
Funny thing they have downgraded Fakra connectors for 4G and GPS to SMA. Also there's no direct 3,5mm jack mic input at the back side of the device.
[FYT Android Head Units] gordgelin:
that is for L880 version probably, L888 has FAKRA and mic plug. At least my device has but i'm 99% sure it is common for all
[FYT Android Head Units] marjanoos:
Good job Mekede with making nomenclature even more confusing.
[FYT Android Head Units] W.West:
Removing the connection of front camera helped. The rear view works now with local radar option on. 😀

Looks like it was interfering with the video signal or it was connected to the wrong input.

Now I have to try reinstalling the system file to make it possible to enable the keyboard apps again.
[FYT Android Head Units] tids2k:
On AliExpress I can only see these outputs for Navifly's 7862S Offerings for the 3D Model. Is this the updated 7870 headunit from Mekede ? Looks like the HDMI port has been replaced with the USB C port. Per my chat with the NaviFly (Mekede ) rep. The L880 specification per attached. The M7 is based on this motherboard L880
[FYT Android Head Units] j0hn83:
Definitely not.

The 7862 came in a couple motherboard/platform options.

The older, more basic option with no fakra connectors, 6800µF capacitor, no dedicated mic port.

Sold by Mekede as M500s, M600s, M700s, etc.

Mekede then released devices on the newer 7862 platform(YL850) with fakra, 10,000µF capacitor, dedicated mic port.

Mekede sold this as M6 Pro or Pro Plus with 2k screen.

It had the option of an HDMI IN port but this meant no 360 camera was possible.

The M6 3D is 100% identical in every way to the M6 Pro. Just a different name and different UI.

The same above goes for the 7870 chipset. There are 2 motherboard/platform options.

There is the cheaper option, no fakra, 6800µF capacitor, no mic port. This is the YL880 platform and it is what Mekede are selling as the M7

There's the more expensive 7870 chipset option the YL888 platform with fakra, 10,000µF capacitor, dedicated mic port.

Both the YL880 AND YL888 have USB-C added.

Mekede are currently not selling the YL888 that I can see and I have seen it on Aliexpress either.
[FYT Android Head Units] tids2k:
Thank you for your clarification. The above picture posted by @gordgelin implies then for the YL888 device and not the YL880.
[FYT Android Head Units] j0hn83:
It was mentioned Mekede downgraded from fakra connections.

@gordgelin just pointed out that no fakra connections on 7870 wasn't a downgrade, he's just explaining there are 2 options of platform.

He's posted pics of both YL880 and YL888 in the last few days.

I think neither were Mekede's.

Mekede will probably replace something like the "M8" for the "YL888" with fakra etc
[FYT Android Head Units] gordgelin:
probably it will be M7 Pro )
[FYT Android Head Units] j0hn83:
Very confusing naming.

On the M6 range the Pro was 720p while Plus was "2k"

I would have guessed the M7 Pro would be the M7 Plus with 1280x720 screen.

Then again, they haven't done sensible naming before. So you're probably right.
[FYT Android Head Units] gordgelin:
My yl880 device labeled as m7 plus on the box ) so yl888 should be pro or pro plus or something
[FYT Android Head Units] j0hn83:
You have a Mekede M7 with a Qualcomm Bluetooth chipset? Or is that a different YL880 you own😂

You have so many units!
[FYT Android Head Units] surfer63:
If Mekede is just as "flexible" in naming their products as they are with their Android levels, you can expect any Mx number ;), but at least higher.
[FYT Android Head Units] gordgelin:
yes my M7 Plus device has YL880 board with qualcomm bluetooth module :)

also a few days ago i've received yl888 device (not mekede)
[FYT Android Head Units] tids2k:
The YL888 device is it from DUDU Auto ? @gordgelin
[FYT Android Head Units] highlandsun:
When I ordered before, 12GB RAM units were out of stock, but I got a msg today saying they're in stock now. I've already got an 8GB unit being delivered soon so I won't be getting the 12GB.
[FYT Android Head Units] W.West:
I tested several firmwares to solve the keyboard app enabling problem. So far IYING one with 20240108 date only works for me.
[FYT Android Head Units] tids2k:
Thats good to know. Im so inclined towards purchasing the IYING one now but also looking at the UI experience of DUDU OS . To wait or not to wait ?
[FYT Android Head Units] W.West:
If you're eager to use DUDU OS, wating would be the option. But since there's little problem from my current experience using the latest IYING firm, it seems good to purchase IYING considering the time cost.

The problem that I have right now is that I don't like the UI of IYING's default launcher, so I'm using Car Launcher Pro. 😅
[FYT Android Head Units] W.West:
I tried that and it gets installed on 7870. However when I set the protocol to fyt and set a map app on pip, the app launches in full screen but not in pip.

When I try to go home, the app restarts in full screen again, which I think it's because of pip.
[FYT Android Head Units] tids2k:
I think there was a change to the most recent launcher. There were two links provided , PIP should work with older versions , if you dont have the apk's I can attach. The newer version does not support PIP.
[FYT Android Head Units] tids2k:
Anyways for IYING firmware, the secret code for entering factory mode :

<action android:name="android.telephony.action.SECRET_CODE"/>
<data android:host="4636" android:scheme="android_secret_code"/>
</intent-filter>
[FYT Android Head Units] W.West:
Looks like I tried the newest one. Can you attach the older version of the apk please?
