Hi all, from 2 weeks i am also owner of M500S UIS7862 4G 64G for my Peugeot 308 2015

I also bought the rear camera and the software navifly to use wit vocal commands. At fisrt installation all worked fine, but after i modified differents setups, i encountered fisrt problem:

When i put reverse gear, i don't ear the sounds when there is an obstacle near my car . I asked at chineese seller, but translation italian/china is much difficult to understand (for the chineese man obviously).

So i decided to make an hard reset from user menù.

But now i have 2 problems:

1. Parking sounds during reverse gear stills not working

2. The Navifly software was disappear and i don't find the apk it into the folders of device to reinstall it.

I'm waiting response from seller but, it's difficult comunicate with him to obtain fastly response. I must to wait one day for suggestions when i contact him for help.

Can anyone help me? Thanks.

EDIT: Seller sent me 3 apk files to reinstall TXZ, NEXAI+ and NEXAI Voice. This problem is solved.

But the big problem now is this:

When i put the revere gear, as well as not hearing the assisted parking sounds, the radar of vehicle in the display, it's not animated, then not change colors (green, yellow and red) when my car nearing obstacles.

Hi guys, I have a navifly uis7862 on golf 7, I have a really uncomfortable problem.

For an indefinite time (which I don't know how to quantify) I realized when I needed to change the settings in the canbus app of the auto settings that the app is read only :O Let me explain better, I can see all the settings, but if I try to change them nothing happens, the status doesn't change, it doesn't overwrite the change.

I have tried them all, I have tried to connect the original radio and it works (change the settings), I have reinstalled the firmware el mcu, I have changed the canbus decoder, I have checked the connections of the connectors and cables, I have done a vcds diagnosis and that's all in the norna, but the problem still exists.

Guys can you advise me something to be able to solve? What happened?

Thank you all
[FYT Android Head Units] marchnz:
Is it an FYT device. Post details with questions for best result.
[FYT Android Head Units] Matt89s:
Sure it's a fyt device, I'm in the correct post. It is a navifly uis7862 fyt = 1 6gb ram 128gb.

By opening the app for changing the car settings (canbus protocol) it is not possible for me to change any value.

I can see all the current values of the settings but if I try to change them nothing happens.

It is sure that the car communicates with the canbus because in addition to seeing all the settings without being able to modify them, the car correctly sends the status of the doors, the external temperature, the fuel consumption values, but does not allow me to change the settings of the headlights for example and everything in between

I have never had this problem, having owned the head unit for almost a year, the canbus app had always worked.

I wrote above that I did all the tests that came to my mind to solve the problem, but without success.

Sorry for my bad english, thanks for the support.
[FYT Android Head Units] surfer63:
Did you recently do a firmware upgrade?

Did you add some mod?

Changed some files (config.txt, fyt.prop)?
[FYT Android Head Units] Matt89s:
I flashed several oem apps like carlink android auto wireless and flying app a few times and edited config.txt file and nothing abnormal happened. Lately I modified the skipkillallapp.prop file by adding the parameters of one of the apps to not turn off the sleep mode by giving the value - 14. But then since the modification was not successful I had brought the file back to the original. But honestly since then I don't think I've noticed if the canbus app worked properly. could it be that? Maybe I have set the wrong read / write values? I believe I have set 644 as values on skipkillallapp.prop
[FYT Android Head Units] surfer63:
644 is fine.

I asked the obvious things, but actually I don't know either.

What is that "flying app"?

And as a side note: Starting with the sc9853i and later, a new file was introduced inside the com.syu.ms being the the unkill_app.txt. I never tried this myself, as I don't care for nokill features, but I also mentioned that I think this is the new way of FYT to not kill apps. I "tempted" other users to try this.
[FYT Android Head Units] Matt89s:
In the past I tried to install the teyes steer button learning apk, but it did not save the values and then I had successfully restored it to the original in its correct folder.

The canbus app has nothing to do with this mod because I'm sure it worked after that too.

I am aware of the unkill_app.txt in ms.apk but I wanted to try on the skipkillallapp.prop before going to create a mod that has to take into account the password and repackaging the apk in a correct way to make it work.

Honestly, I am amazed by this unusual problem
[FYT Android Head Units] Matt89s:
PROBLEM SOLVED. a cable was simply detached from a junction of a cable to the canbus decoder that I had repaired some time ago that was inside a heat sheath. Alas it was interrupted, good for me, thanks to all, always
[FYT Android Head Units] Frenz75:
Anyone can help me to understand why sounds and color radar stopped working in reverse gear? :(
[FYT Android Head Units] surfer63:
Did you check your wiring?

Do you have the correct CANbus protocol?

The car should still "beep" when getting close to an obstacle.

And do you also have forward sound collision warning? So when your front of the car gets close to something, does your car also beep? And if so: does that still work?
[FYT Android Head Units] Frenz75:
Wirings ok, CANbus protocol too. So this morning i disassembled navifly device and reinstalled the original SMEG+. I see in the menu that the parking assistant it was OFF. So i set it to ON and reinstalled the Navifly device to check if it works. When i attached the machine battery i heard an error sound from car and when i tried the parking assistant it was OFF again. So i decided to not unplug the battery car, reinstalled SMEG+ to activate the parking assistant again, disassembled it and reinstalled Navifly without unplug battery. When i powered ON i see that parking assistant works perfectly with sounds ans color radar. I don't understand because i can't set ON parking assistant from Navifly. So from now all works perfectly.

Hi, I just got my Navifly 7862 ordered for Dacia Duster 2019, which will replace my (slow) Xtrons PSA80DCRL (image below).

On the advice of @WaterworthCC I also bought new frame for the 9 inch Navifly (not arrived yet).

In the 7862 package I found a canbus that I don't know about, this one.

In the package there was also a leaflet with some instructions, this one

On the FAQ page for the 7862, there are six types of canbus listed as an example, but not the one that came to me (let alone).

Now the one million dollar questions:

1) Since the canbus that I currently have installed on the Xtrons has allowed me to recover all the car's functions (steering wheel controls, telephone, etc.), can I leave it?

2) Does anyone know how to adapt the new canbus to my 2019 Dacia Duster? The flyer in fact, in relation to the 7862 does not say much. Thank you.

Now I also realize that they sent me a 7862 with the wrong measurements !!! I had ordered a 9 "instead I got a 10" (22.1 x 12.4 cm). :mad:
[FYT Android Head Units] surfer63:
That NaviFly page also has an SS Canbus. I assume that stands for "Simple Soft", but just a different sticker.

Ask NaviFly.
[FYT Android Head Units] Surfer2019:
I confirm @surfer63 , the canbus (as in the photo) is Simple Soft, so the settings should be those shown on the FAQ page, right?

As for the wrong size, I went to my installer and he showed me that the arrived device actually has a removable outer bezel (which I didn't notice) which should fit nicely into the dashboard of my 2019 Dacia Duster (it has the same joints of the current frame). Let's hope so.

I just received my Navifly 7862 for a 21 Toyota RAV4. After install it changed my vehicle to show kmh instead of mph. When I try to change it to mph in the vehicle settings it won't stick and just goes back to kmh. I can't find a setting to change it on the head unit. Does anyone know how to change to mph?

Fixed - I unplugged the canbus box and was able to set to mph in my cars settings. Plugged back in canbus and mph has stuck so hopefully it's good now

Does anyone know how to set APN on these head units? I put in my visible card to test it out before buying another account but I got all bars no internet. When i download a random apn helper from the store everything was fine till I sent it to save the apn settings and it said this user is not able to. :( My guess is I have to do it in another place?
[FYT Android Head Units] Surfer2019:
Hello @surfer63 , I managed to install my Navifly 7862 on my Dacia Duster 2019, everything works (even the 4 cameras), but I sent the manufacturer a message telling him to update the firmware because by selecting the canbus XP, as they wrote to me, to make the buttons on the steering wheel work I had to select Renault>Clio; there is no Dacia brand and not even the Duster option.

Does anyone know if there is a way to "enable networking" for Bluetooth so I can Bluetooth wifi share from my iPhone to this unit?

How does one change the Launcher? I've installed 2 and when I hit home I don't get asked as I would on my tablet what launcher I want to make default.
[FYT Android Head Units] Surfer2019:
Hi, I've been using my new Navifly 7862 device for a few days now, and it's fantastic.

However, I have encountered a couple of problems which I hope you will help me solve.

Reading the external USB and app permissions

I downloaded the Total Commander app to see if I could read the contents of my external USB (music and video). As soon as I tried to open my external USB this screen came out (I translate it from Italian to English):

On Android >=5, the external SD card is write protected. It is necessary to choose the directory from a special Android dialog to give Total Commander write rights. In the next dialog box, go to the root of the external SD card and click on the 'Select' button at the bottom.

The next window is in English and warns me that an app called com.android.documentsui is missing.

After some internet research I found an APK that installed this missing app for me and finally Total Commander was able to access the contents of my external USB.

Problems solved then? No way!

I tried to install VLC (but the same goes for other apps installed). As you can see from the following images, some apps need to have some permissions to work but the system does not allow you to add other permissions to those that it independently decides to give.

I can only see screenshots that indicate the status of the permissions allowed or denied to a particular app, but I absolutely cannot change them.

I have searched through the various options (the three dots at the top right) but all the permissions that could be granted to the apps are listed, but there is no way to select them.

Can someone help me?

Navradio + problem for @KoTiX2

In your video, at this point, you show the procedure for changing the radio station logo. I also perform the same procedure (with Total Commander), but instead of opening the page with the list of logos, the root of the device opens. Why?

Side button lighting

They keep changing color, does anyone know if there is an option to manage the lighting of them? I have not found it.

Thanks
[FYT Android Head Units] KoTiX2:
I was working on this the last week... ;)

During this weekend I'll release an update that include:

1. An advise that say that documentsUI is missing and i suggest to install the filemanager "material files" from PlayStore to select the logos.

This file manager have a search function like the documentsUI app that is useful to search the logo by name.

2. Set the intent to start the file browsing from the RadioLogos folder so it doesn't start from SD root.
[FYT Android Head Units] Surfer2019:
Thanks @KoTiX2
[FYT Android Head Units] DreadfulDrummer:
On the head unit, using an app like Activity Launcher, you can search for and open the Bluetooth 2 activity, pair your phone and enable Internet access in the device specific settings there. You may need to edit sys.fyt.bluetooth_type in your config.txt to make this smoother; more info can be found in this thread by @surfer63 (You might be able to find info on changing the launcher there too)

On my Android phone, I need to enable Bluetooth tethering in the system settings and also check internet access in the Bluetooth settings for the connected head unit.

It's not the most elegant process and I can't say it's worth it or if it will even work with an iThing so best of luck! 🤞
[FYT Android Head Units] surfer63:
That will only work if they have updated the Canbus app as well and added the Dacia. Please ask for that.
[FYT Android Head Units] surfer63:
That's a common issue. You need the documentsui.apk. See "Questions & Answers" Q20 of my "General FYT based Spreadtrum uis7862 (unisoc ums512) - Q&A, Mods, tips, firmware" thread

No. He was on-topic as his question is for his current unit, which is a FYT unit. Not an MTCx unit.

Hi

I bought Navilfy 6GB/128GB ROM QLED 1280*720 BT5.0 headunit for 2006 Suzuki Swift.

Does anybody know how to add launcher themes?

How can i replace radio app. It sucks. It does supprot RDS but RDS text is so small in the corner and radio frequencies are huge.

How can i change settings for steering wheel button that i mapped to src? It does cycle through radio, video, bluetooth and so on, everything. I would like to only use radio and one app (Headunit reloded).

Thanks in advance
[FYT Android Head Units] surfer63:
See for mods. I made many of them for older units. It is not so difficult.

Or look at https://udteam.ru/

I explained that Yesterday here: https://xdaforums.com/t/teyes-cc3.4189041/page-40#post-85131585
[FYT Android Head Units] GlenSony:
Thanks, will check these out.
[FYT Android Head Units] ziddey:
Got the Navifly unit in the mail today! Came with a premade harness for a 2011 Mazda2. There's a canbus decoder, but my steering wheel control is the old style resistor network. I don't believe there's any canbus at all going to the radio harness, but I'll have to double check. I assume once I redo the harness to hook up key1 directly, swc will work.

I did run into an issue with the pre outs, specifically the sub out. Is the gain extremely low on these units? I have it set to passthrough (handling lpf on the sub amp itself), the subwoofer volume maxed out at 10, the amp's gain completely maxed out as well, and yet the output is still extremely low. Connecting a phone directly to the amp, I can get the expected output no problem with phone volume and amp gain both halfway. Is there any setting I'm not seeing? I've tried just hooking the sub out to the amp's left input as well as using a y-splitter. Also tried hooking up the left/right outs to the amp instead of sub out. All produced about the same output.

Also, is there any way to add Widevine support to Chrome or any browser? I'd be happy with just L3.

Does Navifly also block bluetooth devices like Joying? I have a Viecar elm327 clone that shows up on scan but fails to pair. Works fine on my phone.

Thanks

Update: Took a look at the car harness and as suspected, the canbus pins are unpopulated. Cut the sw1 wire and spliced it with key1. Didn't need to set the headunit car configuration to null/null/null; the swc learning immediately worked.

Any idea why I'm not able to control when the headunit turns off? It seems to be ~15s after acc is cut. I found an on/off toggle for setting sleep on ACC, as well as a duration setting under user. Played with both, but neither seem to have any effect. The 3s setting doesn't work but would be ideal.

Edit: Found that the sleep setting is sleep vs powering down. Not sure why the other setting isn't taking.
[FYT Android Head Units] ludditefornow:
I have a generic ELM327 low profile on my car and the Navifly picks it up. No idea on your other points. Good luck with it.
[FYT Android Head Units] ziddey:
Is the single usb plug power only? There are wires for data, and they measure fine with an ohmmeter, but I can only charge. Meanwhile, both ports work fine for data with the 2 usb cable.
[FYT Android Head Units] surfer63:
What do you want to use it for?

USB stick should work and any OBD key with "OBD*" in it's system name. For the rest nothing will work. Hardcoded in the Android code.

Hola Familia .....

Alguien a probado esta Rom en Navifly 7862 qled 1280x720

También me gustaría como poder cambiar la apk de radio, es muy fea la que lleva de origen ..

he probado estos MOD https://udteam.ru/radio/ pero no funcionan, aplicacion no instalada.
[FYT Android Head Units] surfer63:
In English please!

They do not work on the uis7862. Their page specifically mentions for CC2, which is a sc9853i.

There have been some minor changes in the radio app, intents and activiteis when going from the sc9853i to the uis7862.

But I still wonder why they do not repat their work for the CC3. The changes are not that big and can "easily" be done for the CC3.

(That is also why my FytHWOneKey does not work with with the uis7862 radio app and I did not feel the urge to change that yet, having a sc9853i. Also because I switched completely to DAB+).

Can Joying 7862 firmware be installed on Navi Fly 7862?
[FYT Android Head Units] rjsmith2007:
My unit came with no instructions or paperwork. Can someone guide me a bit with connecting the canbus decoder on these units?

I ordered this one from aliexpress: https://www.aliexpress.com/item/1005002308935398.html

In the device info menu it shows the canbus protocol as unknown. I tried selecting the canbus type from the factory menu, but all of the options looked unfamiliar. The canbus box it came with is a Raise branded decoder. But the menu didn't show that as an option. However I clicked through them all and there was only one that listed my car specifically, so I went with that one. Though the issue didn't change, before or after fiddling here.

The product page mentions connecting some pins for the canbus, but I cannot make it out. The image is too small (at the bottom middle of this image).

The larger white connector on the right connects clearly to the canbus decoder. The small black connector plugs into the black port on the back of the unit.

The small white connector with 2 wires on it doesn't fit on any of the ports.

The "audio out" connector fits in that port that references the canbus with the red arrow. That connector has white/red rca cables, and 2 wires labeled TX and RX. Am I supposed to do something with the TX and RX cables?

Really appreciate your help. Googling for this topic and reviewing videos has yielded surprisingly little information. And without any instruction manual I'm afraid to randomly start connecting wires up.
[FYT Android Head Units] surfer63:
You see the small canbus contact on the back at the bottom ("if your car need canbus..").

And you have the harness with on one end the ISO plug and on the other end two plugs: the small white is the canbus plug.

So not the small white with 2 wires, but the small white with many wires.

Hello,

I have some question about the 16/32 band EQ of the 7862 units.

Are the frequencies and the Q factor adjustable by the user?

Picture of the EQ and I have marked the fields on it

Thank you
[FYT Android Head Units] ziddey:
@extremedaneben just checked and it looks like the q factor is adjustable, but not the frequencies.

Also figured out how to get the subwoofer lpf/hpf working. The controls from the equalizer app are broken, but setting the values from settings>devices>subwoofer works.

results in this:
[FYT Android Head Units] extremedaneben:
@ziddey Thank you for your reply.

If it's so, then I might just order a TS10 unit from another company with that 48 band EQ.

Or are these TS10 units with 7862 much more worse then the FYT units?
[FYT Android Head Units] Surfer2019:
In fact, as I wrote before, even though everything is working now, I sent them a notice to update their canbus.
[FYT Android Head Units] Surfer2019:
Thanks @surfer63 ,I downloaded DocumentsUI-10.apk, but I wanted to ask you one thing: looking at the info on my device today, it says it's an Android 11 (not 10). Is it a fake, how did you write here?
[FYT Android Head Units] surfer63:
Don worry about that that. Even though your unit says it is Android 11, it is still Android 10. Read Q1 from the "Questions & Answers".

(Actually: read them all. then you would have known already and did not need to ask).
[FYT Android Head Units] Surfer2019:
Yes, I read everything, thanks for your kindness @surfer63 (if 63 is your birth year then we are the same age) :) . For now I am struggling with the Chinese seller because, despite having purchased the optional voice control for € 17.01 (which I discovered is called NexAi +), I discovered that it is the "Basic" version that does not allow you to interact with the phone, as the "Standard" version does.
[FYT Android Head Units] surfer63:
When I search on Aliexpress for Nexai, there are many suppliers of a license, but they all nicely separate them by basic, standard, pro. The costs for the same license sometimes differ per seller.

I would contact the sller and try to change your basic license for a standard one, of course with a little uplift in price.

And I am afraid you will not be succesful but you can always try.

I got the Mekede M500s unit from Mekede Official on AX. Does anyone know what canbus type I should set for Renault Megane 2 or where I could find this information?

The provided instructions say the type is printed on the sticker but I don't see anything, here is the photo:
[FYT Android Head Units] WaterworthCC:
I think the canbus decoders in the transparent orange case are normally SS/XP?
[FYT Android Head Units] surfer63:
Ask Mekede. They will answer.
[FYT Android Head Units] Hiro0111:
I bought the mekede M700 last week.

The operation was very smooth and there was no freeze.

I turned off the engine, touched the navigation with ACC, shut it down once, and when I came back after 15 minutes of shopping, the navigation was initialized at the factory.

Is this common?
[FYT Android Head Units] surfer63:
I do not completely understand you.

You swithed off ACC and thereby the unit.

When you came back and restarted it, was it really back at factory settings?

Or do you mean it did a cold boot?
