The wifi in these devices are really weird! Yesterday i came back from a vacation (Slovenia) and we drove with my car. So good time to see how the radio works with google maps all the way from NL to Slovenia. First i need to mention: The hotspot had problems on my motorola phone, and changing it to 5GHZ only was the solution. But before the vacation my bank card was not working anymore so i tried NFC on the motorola but hardware seems broken. So the phone is going back for repair (still warranty on it) i changed to a Oneplus 8 and changed hotspot to 5GHZ only. And it worked fine for a long time but when i stopped the car (after like 1000kms) for a short break the radio was again not able to find the hotspot :/ i tried everything! But nope not listed anymore. So i changed hotspot to 2.4GHZ and it directly was connected. So we drove all the vacation with the hotspot @ 2.4GHZ and no problems. Sometimes it dropped but it auto reconnected.

So i really dont know how this is possible? When i parked the car close to my house the radio connected to my home wifi (5GHZ) and works fine.. So what the??

damn, I debating to get this or teyes for my sister's truck. I have a teyes cc3 and am nervous if this head unit will work okay for her instead of teyes . Also, i can get it delivered sooner than the teyes unit so that's a plus. Just worried if it'll have more bugs than teyes.I also didn't like how teyes lock down the firmware. I also noticed the problem with the rear camera did u fix that?
[FYT Android Head Units] marchnz:
They are all FYT units. Don't be fooled by a fake brand name
[FYT Android Head Units] DexterMorganNL:
Sorry to hear this :( I tried Google Maps Cross-Border as well, because Android Auto isn't reliable then. But I had no issues at all with the WiFi hotspot set at 5Ghz.

The only reason my hotspot disconnected, was because I still had a limit set. So could there be something in your hotspot settings not correct?

Still waiting on the Ferrite rings to arrive: I have ordered those, and a DC to DC step down converter. If it's really high frequency noise causing this interference, than I think the Ferrite rings could work.

I'm planning to put one at both ends of the RCA cable: one near the headunit, and one near the reverse light. Although I think it's unlikely, that it's picking up high frequency from there. I guess it comes from the engine, as it only happens when the engine is running.
[FYT Android Head Units] Tweak-NL:
Nope, hotspot settings are fine. I think it is because there is so many different phones and hardware?

But that does not explain why it worked fine for 1000kms on 5GHZ. Just found out Medeke has newer firmware on the website? I think i got this file name 7862-A11-wbt-7-8.zip and the new one is: 7862-A11-wbt-9-10.zip

Maybe there are some bug fixes in it? to bad there is no changelog. I already found out they made some changes in the config.txt
[FYT Android Head Units] DexterMorganNL:
You could try so? In the general thread of UIS 7862 there is a Mekede firmware version, that has the fake Android version removed. But personally I don't care so much about updating the device.

I can't imagine it will bring much improvement: in worse case, it might even become worse. So I'm sticking with what ever firmware is running on my unit. Just want to replace the Car Launcher sometime.

Perhaps this one? It's the only Car Launcher on Mario Dantes collection, that is label for API Level 29. And don't have this FrontApp, but what that car in the middle does do? I'm just a bit lazy, to plug in the USB stick and install it.

Because I'm not using the car a lot on the moment, that's why my unit would switch itself completely off after 3 or 4 days.
[FYT Android Head Units] surfer63:
No. 7-8 is for 7" and 8" units. 9-10 is for 9" and 10" units. And then there is a multi-launcher version as well.

You simply need to download the correct one and check every x weeks to see if that same firmware has been updated. This requires your to unpack it.

And after it didn't work: Did you reboot your device? That can be very important. On every new connection the unit uses a new MAC-address and therefore gets a new ip-address.

If your hotspot on your phone is limited to max 8 ip-addresses (quite common default; check that on your phone) or even less and you had a few stops or interruptions, your hotspot can't hand out more ip-addresses. When you switched to 2.4 GHz the DHCP-pool had to be renewed giving again 4-8 free ip-addresses.

Please check that.

And otherwise: switch off the random MAC-addresses in your unit.

Newer firmware is not a solution here.

Edit: And if your wife, 5 children and 3 dogs each using their own phone on your hotspot, your DHCP-pool is even faster depeleted :D
[FYT Android Head Units] Tweak-NL:
Oh but i downloaded the firmware for the M300S this one is 8 inch. And now when i download i get the 9-10 zip. See the attachement wich radio i got. -> http://www.mekede.com/Software Download Address1/

You already explained about the ip adresses in a other topic, and i also said there that is not the problem.

When a DHCP table is full the phone cannot give anymore ip adresses. That has nothing todo with finding the hotspot in the wifi list, it should be there.

When the radio is off (bluetooth will disconnect) then also my hotspot will be turned off. So when you turn it back on all the leases are gone. And yes, after that 1000kms of driving i rebooted the radio and turned hotspot off and on but nope not listed. i even restarted the phone. And like i said when i came home from the vacation it still does not work. But it can find my home wifi @ 5GHZ and works fine.

This is really a weird problem. So i hoped maybe with new firmware that problem will be solved.

Edit: and on the radio i cannot find the settings to turn random mac adresses off.
[FYT Android Head Units] DexterMorganNL:
I finally received the Ferrite Beads, and already attached them to both ends of the RCA cable. The 3.5mm fits perfectly on the RCA wire, and its easy to put them on.

The photo isn't really sharp, but here is where I put Ferrite Bead just behind the RCA connector. Also I attached one, close to where the reverse light is located. Because I'm not sure where the "high frequency" noise/interference is coming from.

Not sure though if it works, because I'm stubborn and don't wanna start the engine unless I'm really going go for a drive. But I think these Ferrite Beads are my biggest chance, because I don't believe the voltage needs to be turned down.

If I'm not mistaken: these reverse camera's should be totally capable, to function with either 12V when ignition is on ON. Or 14V when, the engine is running. But I wasted some extra money for supporting China's economy, by ordering stuff I ain't going use.....

€ 2,41 53%OFF | 10pcs 2pin Quick Pluggable Splice Electrical Cable Wire Connector Crimp Terminals for 22-20AWG LED strip Car Wiring Connectors

https://a.aliexpress.com/_EwMjYER

Like these connectors, to put on wire's you wanna connect with each other. I decided not to use them, because it doesn't look reliable to me.
[FYT Android Head Units] DexterMorganNL:
Doesn't work, only thing left to try is the DC to DC step down converter that I ordered. But I'm getting tired of trying to solve this interference.

Have you ordered a DC to DC step down converter as well? The idea was, to convert the voltage from 14V down to 12V.
[FYT Android Head Units] surfer63:
Sorry. Either I only saw it just now (after your edit) or I forgot to answer this one. I can't remember.

In your WiFi settings you have your connections (the SSIDs of the WiFi networks).

Say you are connected to "My_HotSpot".

Click Settings behind the SSID (the little "gear" wheel)

Go to Advanced => Go to privacy => Select "use MAC address of this device"
[FYT Android Head Units] roti86:
Hi,

No, have not ordered anything, not even the ferrite beads, I wanted to wait for your feedback, but looks like it does not work. Please let me know if DC to DC converter helps, but my interference is negligible.

Thanks for your feedback, appreciated.
[FYT Android Head Units] DexterMorganNL:
None of it works, I'm going keep it the way it is. Could be totally the 12v which it gets from the reverse light, but I couldn't measure the voltage when the engine was running.

I tested it three times: also one time without the reverse camera connected to the power, but the trigger wire still connected. No interference in that case, but no video either ofcourse.

So I have given up: I ain't going run another cable all the way from the headunit, to the reverse in order to power it from the headunit. Assuming the A5 wire provides 12v, but in any case with non canbus you need to have the trigger from the reverse light still.

@roti86 if you have any idea? Let me know? I think any "noise" filter related, won't help. But if it's related to the power connection, than perhaps you could try powering it directly.

For me I think that's to much trouble to go through, so I won't bother. But it could be the actual solution.
[FYT Android Head Units] DexterMorganNL:
Android Auto disconnecting when crossing borders still continues, even though my Xiaomi phone had a update recently. So it turns out this is issue within Xiaomi phones....

Because Germany is like a third world country in terms of mobile network coverage, that means every once in a while the phone will change network during roaming. Result another disconnect, so for international travel using Google Maps on the headunit is more reliable than Android Auto. But I still prefer Android Auto, because it's convenient to use when you drive short distances within the country.

Battery consumption on Android Auto is quite high, it drained my phone for more than 20% while driving 1.5 hours.
[FYT Android Head Units] adioperator:
Hi guys,

Does anyone know where in the menu I can make this "snowflake" button bigger? I remember that I found it once but now I don't know where.

One more thing: can the font size be increased?

Thanks!
[FYT Android Head Units] leo06:
It’s an app, touch assistant or something similar. You can found it in apps
[FYT Android Head Units] DexterMorganNL:
Me trying to solve the interference of the reverse camera, has led me to a new project: I'm retrofitting almost all my light bulbs. I started with the headlight's, using a in Germany road legal Philips H4-LED.

Then I finally changed the reverse light to LED, by which I kinda forgot already why I wanted to do it in the first place. To see if it could help with the interference, but it didn't sadly.

And after that I got the idea, to also do the taillights and domelight. For the taillights I used Osram LEDriving.

The domelight was the cheapest, and actually the LED light I was most surprised by.

I still have ordered more: some indicators, brighter reverse light. And LEDs for the license lights. But I still haven't solved the issue with interference, which I'm going give a last try before or after my holiday. ( I'm actually going to Hongkong China, to visit my parents in law. But order stuff from AliExpress is easier, and more convenient than searching for it in Hongkong )

I have ordered a 5m power cable, a relay and cable which allows me to tap into the fuse box and get a clean 12v. But before I will pull another wire through the car: I will first test my theory, by hooking the reverse camera up to a small 12v battery and then run the engine. When the interference is gone, than it's definitely an issue with power coming from the reverse light. If the interference stays, than it must be EMI interference.

Other than this, the headunit is working like a dream. Once you get used to the silly bugs, it's actually isn't bad at all.
[FYT Android Head Units] leo06:
If with battery camera is working fine then maybe is easier to run a single cable from headunit camera power to the back of the car.

For the headlights I tried the led bulbs but I wasn’t satisfied with the result and finally changed the headlights with projectors and xenon hid. Way better results
[FYT Android Head Units] DexterMorganNL:
Actually it isn't easier: it's difficult to reach that headunit wire, without taking loose the headunit. Running a wire from the fuse box to the back, would most likely be easier.

I already have the wire of the reverse camera, lying below the floor of the trunk for easy access. As I was getting tired, having to pull loose these panels to get to the wire.

Because of the long shipping times from AliExpress, I basically ordered everything already I might need. And looked up where this fuse box is located.
[FYT Android Head Units] DexterMorganNL:
I finally solved the interference: it was the ground wire, it wasn't grounded properly. During my holiday in Hongkong i figured out the wiring diagram of the right rearlight unit, and it turned out there was only one ground wire.

So I tapped the reverse camera ground wire inside there, put a tape to keep it on it place. And finally after trying many possible solutions, it worked. Didn't need the relay in the end.
[FYT Android Head Units] ale_rx:
hi dexter, on the first page you said you bought your headunit from poland, could you tell me where exactly did you got it from?

i'm looking for a m700s shipped from eu... so if you have a seller with eu warehouse please pm the link
[FYT Android Head Units] DexterMorganNL:
I bought it from Xi Jinping, and he has a warehouse in Poland: so just look at AlliExpress, and see if they can ship from a warehouse from Europe.
[FYT Android Head Units] surfer63:
Really ??? :D

You bought it directly from the president of China?
[FYT Android Head Units] DexterMorganNL:
Actually I bought it from Winnie the Pooh, who happens to be the President of China: lucky I'm back in the Netherlands, because a few weeks ago I was still in Hongkong China....

But no I was joking: I just think, it shouldn't be so difficult to find Mekede on AliExpress and see what the shipping options are.
[FYT Android Head Units] DexterMorganNL:
I solved the interference already: it was a ground issue, the reverse camera wasn't properly grounded. I'm guessing the interference you talk about, is just because an analog signal isnt 100% free of interference. So I have very little interference as well when reversing, but not as bad as before. So i'm very satisfied about the AHD reverse camera now.
[FYT Android Head Units] roti86:
Glad you found the issue, sorry for the late answer, I have been only read-only mode lately. I also checked the connections and cables especially the ground cable, I even tried the camera without the bulb as mine is grounded directly to the cable, but the small interference was there when engine was running.I could not eliminate this small interference so I will live with it, it is not that distracting.
[FYT Android Head Units] DexterMorganNL:
Analog signals are quite sensitive for all kind of interference, so it's difficult to get rid of it 100% totally. I just wonder sometimes, why it's still analog anno 2023 and not digital .
[FYT Android Head Units] DexterMorganNL:
I have been messing around with FYT Launchers, and this one I found on @mariodantas collection of Launchers. The funny thing here is, that this launcher didn't show before.

It's launcher 29 and I already had a preinstalled launcher, with number 29 and because I didn't remove the preinstalled one. This one didn't show in factory settings....

But I guess somehow, it has overwritten the other launcher with 29 as number. Only this happened, after restoring the FM Radio app. Because after I removed it, as it conflicts with NavRadio+ from @KoTiX2

After that my Launcher became crippled.... clicking the radio button in the launcher, would ask me which app to use. And if you pick the app, it would crash and the default launcher would show again.

So I have restored the original FM Radio app because of this, because I don't like a crippled launcher.
[FYT Android Head Units] DexterMorganNL:
I have turned in my Suzuki Celerio for a Nissan Leaf Tekna of build year 2019, so that sadly means I won't be able to make any contributions anymore to this FYT unit. But actually I'm happy that I ain't going have a crippled headunit anymore, as AF wasn't working properly and I had issues getting the reverse camera to work properly. I just hope it aint going be an old couple, buying the car and then don't understand how the headunit works hehe.
[FYT Android Head Units] surfer63:
Good for you. Integrated head units always work better.
[FYT Android Head Units] DexterMorganNL:
Yes, and I even though the builtin navigation wasn't half so bad: but the best thing, I have 360 camera and not just a reverse camera. Android Auto is also included and perhaps I will finally find out, if my issues with Android auto would have been related to the headunit?

Just its not wireless: so perhaps still order such a carlink dongle, to make it wireless.
[FYT Android Head Units] marchnz:
Yes your android auto issues were related to the head unit. These Chinese knock offs are not sanctioned android auto.

No I don't want a sourshiz account.
[FYT Android Head Units] DexterMorganNL:
I don't know, it was working fine before.... but I have a suspicion, that Google might have changed things that it stopped working properly?

But anyway, I still have the car until 12 april: just I won't bother doing any modifications anymore.
[FYT Android Head Units] marchnz:
Sorry to see you go....
[FYT Android Head Units] DexterMorganNL:
Well I really wanted to drive an electric car, and now you still get subsidie and no need to pay roadtax. And still some possibilities to charge for free.
[FYT Android Head Units] Minisonny:
Hi, when I use my phone to share a 5GHz wifi hotspot, the head unit cannot find the access point. But if I switch to 2.4GHz, the head unit can find the wifi. If I understand correctly, m500s should be able to receive 5GHz wifi. What should I do to check and enable the 5GHz capability?

Thanks!
[FYT Android Head Units] j0hn83:
The FYT units cannot see high numbered 5GHz channels, such as 149+.

These channels tend only to be used in parts of Asia and are actually banned in many countries.

You must use a lower numbered 5GHz WiFi channel.

With Xiaomi phones they automatically want to use channels 149+.

The only way I can get my Xiaomi (Poco) phone to use a low 5GHz channel is to be connected to a WiFi channel when I start my hotspot.

It will then use the existing WiFi channel I was already connected to.

So if I am connected to my home WiFi on my phone in my driveway (5GHz channel 36) then I open hotspot on my phone it will use channel 36 and the heat unit sees it.

However if I am away from home and open hotspot it uses channel 149 automatically and my head unit cannot see it.

For this reason I must use 2.4GHz WiFi until I get a new (non Xiaomi) mobile phone.
[FYT Android Head Units] DexterMorganNL:
Android Auto in mine Nissan Leaf from 2019 is working perfectly, even though only wired. Now I realise, how bad the whole after market system was.

The only thing better was the screen resolution, because there is where Nissan saves money. But other then that: I can easily tell Google assistant, to play a certain song. Without having to repeat it 10 times or speak super loud.

Hello. I bought a Mekede m600s radio for a Mercedes A-Class vehicle. Radio works fine, so does carplay, but I'm having trouble with things like temperature, adaptive dimming, tank level, etc. The can-bus profile is HIWORLD and it offers (among other things) only B200 or Old Compatible. Is it possible to somehow add a profile for the W169 vehicle to the radio, thanks to which it would be possible to read and set things like the outside temperature, lights on, tank status, etc.?
[FYT Android Head Units] marchnz:
Hello.

This is a common question from new members.

What does the seller suggest and what has been tried. What were the results of your trying.

What posts have you read from this subforum that help. Have they been tried.
[FYT Android Head Units] rotujicikedluben:
Informace o rádiu:

I got a HIWORLD canbus decoder for the radio.

In the settings, I can choose between B200 and OLD (open door information also works here).

I would like this information to work:

The seller advised me to use B200 and now he is silent.
[FYT Android Head Units] mastrv:
First thing, if your car did not have or show this information before, chances are that the information is not available on the canbus.

Second, these canbus modules are not 100%. It's hit and/or miss. There's the module itself and then the software on the head unit that uses or works with the module to interpret the data coming from the canbus module. So if it's a popular car or the developers own the same car as you, it might work because they would have spent more time on it and could also test it.

Third, that application and the information displayed are not that useful and are usually available elsewhere on your dashboard. Usually, most people will be driving with a navigation app running and possibly the radio or a music app.

Lastly, just because you only see two possible options doesn't mean you can't try other models. In fact, you might want to try Chrysler models as Mercedes was working with Chrysler for a while so they might share canbus codes. When selecting the car model, you are telling the head unit which code to use to interpret the canbus data. I'm pretty sure no damage will happen if you try other car models.

In any case, I wouldn't lose sleep over this and just go on your way if it doesn't work.
[FYT Android Head Units] rotujicikedluben:
Of course I tried all possible settings and different canbus profiles. Of course, I could do without a lot of information, but I would appreciate at least auto dimming because it was on the original Audio 20 radio.

The question was whether it is possible (how and with what) to update the canbus, radio or mcu (or something else) that could help.
[FYT Android Head Units] j0hn83:
The auto dimming is controlled by the Illumination/Light wire.

Your cars Light wire should be connected to pin 4 of the power port on the rear of the Mekede.

This makes the unit dim when lights are turned on and the side buttons light up.

The other info is usually only available if the original radio showed it.

You cannot make your car send fuel level/temperature/voltage info over wires that never carried that info originally.

Some cars do have that info on the Can L/H wires despite never showing it on the original radio but most don't.

My car only shows this kind info on the instrument cluster and it isn't possible to send it to the heat unit.

Almost all canbus boxes can't be updated despite there being a menu for doing just that.

That menu is more for custom canbus boxes made by some sellers.

I've never seen a Hiworld, Raize or Simple Soft XP canbus box updated, or even an update file.

The only thing that can be tried is using different vehicle profiles in the canbus menu, or trying a whole new canbus box as some boxes work better than others.

Most of the time the seller sends the best box for your vehicle (but not always).
[FYT Android Head Units] surfer63:
Update the MCU does nothing for your CANbus.

Updating the CANbus decoder/firmware is not possible.

Your only small chance is to update your application layer as it will contain a newer CANbus apk which might contain new/enhanced/extended functions.. It is from November 2021. The latest ones are from May 2023. And while your at it: Also update your kernel (base Android layer) as also the latest kernels are from May 2023.

So what is your reseller, your fyt manufacturer id, bluetooth sys setting, etcetera.?
