Could you also share the HDMI360 apk they sent you in case anyone needs it in future?

If it were me I would be tempted to try a (very) temporary fix (not with solder) to check if bridging those 2 sets of pins fixes the issue. If it does give audio then I'd hand my unit in to a local repair shop that I'm familiar with as that's too small a fix for my DIY soldering kit and my skills.

It's a dedicated apk for playing the HDMI in source. They finally sent him it (he confirms a few posts ago). You can see in the video the app is named HDMI1.
[FYT Android Head Units] surfer63:
I am sorry :)

I only watched the first part of the hardware modification. The rest I skipped.

But it seems they also installed another com.syu.ms?
[FYT Android Head Units] DJBBOX:
Does anybody have a working link to this file 7862-A12-wbt-9-10.rar I think this is the latest update to the FYT 116 6315 units or if anybody has the latest firmware please share, all the links I found even at the manf site are dead end
[FYT Android Head Units] j0hn83:
Edit: correct link: https://drive.google.com/file/d/137ZFT1jonAPdiVJHheveaGG0Anwgrv8G/view?usp=drivesdk
[FYT Android Head Units] Dudgeware:
I don't think so (No expert either), it's an app on screen that simply allows you to switch the unit to the HDMI Input. Will be posting what they sent in a moment...
[FYT Android Head Units] DJBBOX:
sir you are gentleman and a scholar thank you
[FYT Android Head Units] Dudgeware:
Sure... They sent me two APK files, I'll attach them here. The first one wouldn't install because it was already on the system, the actual HDMI APK did install & works fine for video, but no audio.

I suppose I could try connecting all the essentials on my workbench & try crossing the contacts to see if the fix actually works, will let you know the results later. Have to take it out the car again, been out earlier with the kids so had to plumb it back in.

Not that I should have to (it should work out the box) but I'm willing to go to reasonable lengths to try getting it working, but before I do I need to be assured that if anything goes wrong they'll still cover it under warranty. If some bloke at the local phone shop can do it for under 30 quid, great, in my eyes that's covered by the refund for the Fake Android 12 issue. I'm still sure it could be fixed with software though, as I would definitely have noticed no audio when I initially tested it. The box model label says "+HDMI" and the unit itself says "+HDMI" so any mod needed should have already been done.

Aliexpress have also refused my appeal on the missing item (HDMI Output), even though it's clear in my unboxing video that it wasn't there, they say I've not provided enough evidence. I've filed a claim with paypal.
[FYT Android Head Units] Dudgeware:
They did. On my unit, it refused to install because it was already there.
[FYT Android Head Units] j0hn83:
You can force it to install as a flashable zip. Perhaps someone will download the com.syu.ms and make it in to a flashable zip for you or I could do it later this evening.

Thanks for sharing the files and so quickly.
[FYT Android Head Units] DJBBOX:
I got an error SIGBUS
[FYT Android Head Units] j0hn83:
That's not an error I've ever seen before.

I shared exactly what Mekede uploaded to the nutstore.

Perhaps try copying the files again or use another sd card?
[FYT Android Head Units] Dudgeware:
Ok, yet another couple of hours spent taking my dash apart & fiddling with this Mekede unit. I can confirm the mod does actually work... 90% ish....

I set it up on my bench & got my hoppo to use a tiny screwdriver to cross each pair of contacts while I operated the front of the unit. Very damn fiddly. He's got good eyesight & still needed to borrow my glasses to see what he was doing :)

It seems each pair is for one channel of audio, so crossing both gives stereo. No sparks, it still works, so all good. The reason I say 90%ish is because I decided to check everything while it was out of the car, and I found it doesn't work as it should with the built in spatializer, as in the balance to left or right, front to rear. All other apps do (radio, stock music, musicolet, vlc), this just gives stereo sound balanced all round regardless of other settings, so the mod still isn't perfect.

I'd be happy with it, and may now take it to someone with the capability to get it done, provided their insurance will cover the unit if they f it up. Would also be nice if Mekede would cover the cost, but as I said previously, they already kinda have with the refund for their fake Android 12 claim.
[FYT Android Head Units] j0hn83:
Great result! I'm glad you're on your way to getting the HDMI input working.

I'm sure sharing an the details will help others in the future.
[FYT Android Head Units] Dudgeware:
Would that be needed though? I don't know whether it's an update to the existing one on the system, but now that I've confirmed the mod they show in the video does actually work, unless it fixes the spacializer issue I don't think it's worth messing with any further.
[FYT Android Head Units] Dudgeware:
That's why I'm posting in detail & providing what files I can. So far after a week on google & this forum, it seems I'm the only one who's had this issue. All was fine until the factory reset, why it now needs a hardware mod is beyond me.

On one hand, Mekede have been a pain in the ass to deal with. Once response a day, usually without understanding the issue, it seems they use a cheat sheet for standard responses in English for common problems. They didn't get to grips with this until it went through the Dispute stage with Aliexpress. On the other hand, since then they have provided a working fix with clear video instructions, even though your average Joe would have no chance of doing it, and in all honesty, shouldn't need to for something they've paid for that should work out the box.

It's a bank holiday, may have a few drinks to steady the hands, put three pairs of glasses on and have a go meself later :)

Next post could be full of tears :(
[FYT Android Head Units] j0hn83:
Not now no. It would only have been worth updating if you weren't going to try the mod or the mod didn't work.
[FYT Android Head Units] DJBBOX:
Yes sir. That did the trick and happy to report all issues are solved execpt for a minor annoyance, the video displayed from the video app looks like if it was zoomed but there is no settings to change withing the video app
[FYT Android Head Units] babkha:
hi all! . Does anyone know where in Europe to buy a head unit MEKEDE/Navifly UIC7862 for Honda Jazz 2003? maybe someone knows the links to the EU Warehouses of aliexpress. I don’t want to buy in China, because I pay a lot for customs clearance. Thank you
[FYT Android Head Units] surfer63:
Watch the other thread where you asked the same question. That has already the answer.
[FYT Android Head Units] bdnstn:
Hi guys,

I have gone through the whole thread hoping to fine answer to my question but it seems I am o my own.

I bought the Navifly M500S 4G 64G with the ADAS DVR front and rear double recording camera. Unfortunately, it arrived with no manual or instruction. As this will be my second HU and camera installation, I felt it will be as straightforward as my first. I was wrong!

Everything seems to work fine after installation. The front and back camera are recording okay when viewed the HD DVR app is opened. However the reverse camera does not come up on screen when gear is moved to reverse. But when I hook up the red CAM 12V wire with the brown BACK wire, the reverse camera displays even in packed mode and will not allow you to do anything else on the HU. Nothing happens when the red wire on the RCA cable is connected to the red CAM 12V or the brown BACK wire.

With my limited knowledge, I am thinking this may have to do with the wire connection required since the DVR front and rear recording camera are kind on linked together before going into the HU. I may be wrong but having asked for help from the customer support since a month now with no real help forthcoming, other than willingness to reply every message and repeating obvious opinions, I found myself here.

I just need help in knowing how to connect the reverse camera so that it displays on the HU when the gear is shifted to reverse.

Thanks in advance.

Yay! I did a thing!

With a bit of dutch courage, I had a go at the modification & although it was a right bugger to do, I got there in the end. I made a video for others to see, I've set it as unlisted on youtube for now because I noticed an error I appear to have made twice. I said earlier that the spacializer didn't work & I was wrong. I only noticed when I watched the video I made that when I tested the HDMI I used the "surround" option in the mixer. For the other apps I used the "field "option. I must have made the same mistake when I tested on my workbench, because I've been & checked & when using the "field" option it works fine. So, mod works 100% as far as I know.

Here's the vid for those who are interested:
[FYT Android Head Units] Dudgeware:
Hope this helps....
[FYT Android Head Units] bdnstn:
I have seen this in some responses but not sure it helps, Below is the camera I got from Navifly and the wiring seems to be a bit different from just a single rear camera.
[FYT Android Head Units] Dudgeware:
Looks like the same kit that I got. You say that both cams are working and that the problem is when you go into reverse, so it's either a problem with the reversing wiring or a setting in the options. From memory, the rear cam has a main lead that connects to the front cam, there's a black that goes to ground and a red that connects to the reversing light. At the front, there's a usb connection, I think there's an rca for the rear view connection & another wire that connects to the reversing light lead. There's also an option in settings to enable the rear view on reverse. I'll have a look tomorrow when I get the chance.
[FYT Android Head Units] surfer63:
Nice you fixed it.

However, being Dutch I always feel slightly insulted ;) when someone mentions "Dutch courage".

So here a little history why Dutch courage is actually "English calm down and reduce fear for".

And why the English should be thankful for their gin.

I just installed a M700 (7862, 8Gb) and am having issues with both USB and Wi-Fi tethering through a Pixel 7. Both options are unusably slow. I've tested the hotspot with other devices and have no issues, just issues with this headunit. Mekede support is no help so far, anyone have suggestions?
[FYT Android Head Units] louforgiveno:
What speed tethering does your cell plan include? Are your speeds looking like 3g speeds?

Also if you haven't yet, set your phone's tethering to use 5ghz instead of 2.4ghz
[FYT Android Head Units] surfer63:
To add to both of @louforgiveno 's questions: What is unusably slow? What are your down/upload speeds? "unusable" is a very subjective statement.
[FYT Android Head Units] bdnstn:
Thanks @Dudgeware This is now resolved. It never crossed my mind to test if the red wire on the RCA actually had power. Apparently, the connection on the reverse bulb didn't make good contact and was the reason it wasn't switching when in reverse mode.

Do you know the pass code to enter factory settings? I need to switch between PAL and NTSC cos I can only see grey picture in reverse mode.
[FYT Android Head Units] Dudgeware:
3368 should do the trick.
[FYT Android Head Units] j0hn83:
The pass is 3368 for Factory Settings (168 On Teyes).

These units support both PAL and NTSC with no toggle to switch between.

There is a toggle to switch between AHD or TVI/CVBS reverse cameras.

Anyone encountered a problem with START STOP car function not working after replacing stock navi with M500S? Nothing has changed on my car except this unit. As far as power connections are made everything looks ok. Unit powers off with car (standby) and after 48h it goes into full shutdown.

I've checked my car manual and none of conditions mentioned in manual are met for start stop to stop functioning. There is no warning on dashboard that function is malfunctioning.

I saw one option in navi factory settings "Automatic start stop" and I tried with ON and OFF, nothing changes. Car is Suzuki Vitara manual.
[FYT Android Head Units] matic7:
Maybe you have some battery issue. START STOP often stops working when battery voltage drops under 60% or lower, depend from a car. I'm guessing you spent quite a bit of time in a car with not running engine while you were installing and testing the radio. If the voltage drops below a certain level, the car starts to turn off the consumers of electricity, but the car continues to start normally. I assume you have an AGM or EFB battery in your car. At least it should have it according to the START STOP function.
[FYT Android Head Units] Racker_CRO:
Yes I was a long time in car setting the radio. Tested my my car battery and it reported ok. I tried to play with car settings and once I set start stop option to economy it started to work. I set it back to standard and again it worked. So either this option change helped or battery was charged in last two days of driving to work and back home. So for now I've solved all issues with this device.
[FYT Android Head Units] nkbyrr:
Thanks for the responses. I was getting around .08 Mbps down, .5 up. I ended up doing a reset on the headunit and it works much better now.

Hello friends, do you know how to increase the volume gain of this Mekede m6 pro plus radio, it is close to my old M700s and too weak in gain, its maximum volume is half..
[FYT Android Head Units] Somgeym:
Hello;

I don’t know if this can help, but when I use the Youtube app, the sound is low and of average quality, but when I use the Bluetooth or the Youtube music app, the sound quality and volume is much better.

I have a Navi fly.
[FYT Android Head Units] arca114@gmail.com:
It has the general volume setting there you can adjust the types of volumes like GPS, radio, Bluetooth etc. I just can't tell you how to access this setting because I'm at work right now.
[FYT Android Head Units] Somgeym:
OK !
[FYT Android Head Units] surfer63:
And there is in the Settings app: Device -> Sound -> Power Conditioning (absolute output volume from 0 to 60, all other audio settings are relative; if you think your audio is already too loud at position 5 (or so), you can decrease the absolute volume output here which means that Volume 5 is now lower ))

Read thread "General FYT based Spreadtrum uis7862 (unisoc ums512) - Q&A, Mods, tips, firmware" post #1, "FYT settings explained"
[FYT Android Head Units] Somgeym:
yes ! i will test
[FYT Android Head Units] arca114@gmail.com:
So friend of this radio and different and is not 60 the maximum, see the attached image. The volume is still weak..
[FYT Android Head Units] Johnny#C#:
I have found a solution with my microphone that worked very weak after the 2022 update on my 2021 7862 unit. I couldn't go back to the older update that worked, it needed an lsec6315update file newer than 7/2022. So I made tests with my older (11/2021) AllAppUpdate.bin. I ended up with a .bin file tha uses all newer apps together with a few old vital-apps that make my microphone work as it did.

Neither the switch in Factory settings nor the config.txt settings change anything, except this hack.

The issue now is on my Bluetooth Speaker volume, when making calls it comes very weak. All other volumes use a global level and equalizer setting, when making calls it uses it's own settings. In order to hear normally I need to have it in high levels, almost 30. Before all those 2022 updates I used the same calls speaker level to 10-13.

I have noticed that all music is a bit lower than 11/2021 update, but this is not a problem because music and navi comes almost at same levels, something that wouldn't happen before (navi was lower than music, although I had it set in loud mode). I also notice that in factory settings there are Volume Balance options but none of these do nothing except Music. All other levels change nothing. Trying to increase persist.btspk.gain=7 in config.txt changes nothing.

Any ideas on this? Is there a way to enable Volume Balance Settings or set speaker gain in a file?

Thanks
[FYT Android Head Units] surfer63:
What CANbus setting do you use. Some come with a HI and LO version, where the only difference is really the audio output.

Now that these power conditioning is in the Settings, these Hi/LO CANbus configs are disappearing, but you might still try.

Few questions about M500s:

- radio volume doesn't lower when navigation is speaking although I have enabled "GPS Mix" and set Sound mixing scale to max 20; I've also set Volume balance settings and set radio to 0 there and all others to max; I'm using Waze as my navi app; navi sound is just played over radio a bit louder; using stock radio app

- is there a way to sort contacts once synced from mobile phone? They are sorted ok on my mobile phone but on head unit they are not (we are using diacritic letters)

- how can I check which version of FW I'm using and if there is a newer one? I'm guessing I should look HERE and select 7862/9" 10" ; I tried to sign up for download but I keep getting strange error

- I also noticed every time I start my car, radio is playing and that's ok but I can't change radio stations using my steering wheel buttons UNLESS I first open radio app. If I set radio app as start up app it will start in full screen and I don't want that
[FYT Android Head Units] surfer63:
Have you set your navigation app in your Settings (Navi app). That's how the unit know when you navigation is "speaking" and all the rest should be lowered.

No

Simply via the Settings device info.

The radio module is a piece of hardware that starts playing as soon as your unit wakes up (unless you disable this). So it starts playing before or without your app being active. That's why you can't change it. You use the SWC buttons to change for the active audio app.
[FYT Android Head Units] Racker_CRO:
Yes waze is selected as main navi app.

EDIT: solved! Sound mixing scale needs to be LOWERED. I set it to 3 and it works like a charm.

Well sometimes radio doesn't start up automatically and I think it's when radio wakes up from complete shutdown (car not started in 48h hours ). What do you mean "use the SWC buttons"? I did configure my steering wheel buttons and they do work but only when I open radio app after boot. After that I can go back to launcher main screen or any other app and buttons will work for radio station change.

Thank you for your answers 👍.
[FYT Android Head Units] Spark972:
I never dealt with any of these update as I'm a new comer (unit bought in December) but since the beginning my BT volume is lower than anything else, I need to crank the unit to level 30 (max volume) when on call to hear the caller.

Also the incoming calls melody is way louder than anything when I'm listening to usb/streaming/youtube, it just blast my hear anytime (can't lower this into the settings).

So when someone call me, I need to lower the volume to avoid that loud melody, check who is calling, then answer (if I wish to), raise the volume to the maximum to hear the caller.

Of course I already played with the mixing board but can't solve this issue.

[FYT Android Head Units] Johnny#C#:
I agree, this happens on my unit too, using update from November 2022. As an older owner I faced the microphone volume issue after the update August 2022. Before that, Bluetooth calls were working properly. I used the older AllAppUpdate.bin and microphone works. As the BT speaker volume worked better in older firmware updates (2021) I suppose something in newer makes it lower, just like the microphone. Maybe a configuration in a file, as none of the settings menu fixes that. Factory settings for volume balance do not work for anything else except music.

I also noticed that music (eg radio) was a little louder with the older 2021 update, than the newer, for the same volume level. This is not an issue as Navi in older update was lower than music and now is better, but I suppose with the same way it was configured from a setting or file, it maybe can fix the BT speaker volume. All gain settings in config.txt failed, nothing made any change. Alternatively if there is a way to activate volume balance settings, it could be a solution to gain the BT speaker.
