CANBUS WORKING intermittently - MTCD Android Head Units Q&A

My Kannor Px5 CANBUS doesn't work sometimes with wheel keys.
It has been working properly around a year. One hot summer day I entered the car and head unit started smelling burned. Since then CANBUS worked intermittently.
I was using Kanor original Rom. I also installed Hal9 rom and update mcu to newer versions but the result is absolutely random, I can't figure out what causes the problem. Even sometimes after a clean rom installation works perfect but then after some days or some launcher installation (FCC launcher) stops working.
By the way, my car is a Nissan Qashqai j10 and I already tried with several canbus options in mcu options with same result.
Any help will be appreciated, it's really uncomfortable driving and using radio at the same time without using wheel buttons.

It's a hardware problem probably a bad connection or solder joint. First check the wiring then open the HU and look around you might see some discoloration on the PCB since you smelled burning. Just redo the solder. If you see nothing just touch up the solder on large pins and be careful not to create a solder bridge and short something out. If it still acts up after that check the CANbus adapter PCB.

@nick2k many thanks for your help.
I followed your instructions. Opened HU to check inside and all was fine there, any burn area or decolored part.
I also checked all junctions and connections.. all of them are correctly connected.
I don't use any canbus adapter so it can't cause the issue..
Could be a software problem between Rom and Mcu? I can't guess what happens here. Other ideas..?

Have you considered tracing the canbus connections following the MTCD schematic to validate that the can bus signals reach the MCU. If this is above your abilities, suggest finding a local repair shop/electronics tech to assist.
Schematic in my signature.

@marchnz , many thanks, you are absolutely right, it's above my possibilities[emoji3526][emoji16]. Unfortunately in this area true are any specialised android head unit service, anyway I'll will continue investigating by myself.

Of course at this point it could be anything but I thought you said you tried CANbus options did you set it back to what it was originally? Your wheel keys must be using the Key1 Key2 wires find out where they are and wiggle them see if that makes the wheel keys start or stop working.

I set canbus option back, even updated mcu with no results, I will try what you recommend me. Thanks

After doing some tests I discovered that when steering wheel is rotated canbus works properly, instead, when you steering wheel is straight wheel buttons don't work, so I guess I must check wheel buttons connection. I will do it and will update you with more news

I have the same problem now nothing work
From wheel key, and the led light on the unit key stop light and no reverse camera work , I think the canbus dead, the car settings fonction work good from the wheel so I think it's canbus problem key,

I would suggest you check your ground and power connections including the connectors.

It's a steering wheel problem, I already checked installation and all is ok, I also installed original car stereo and the problem is the same so he issue must be in the inner part of the steering wheel, technicians will check it soon. I will let you know

After being checked by car service the problem is in the ear bag ring. The price for changing that part plus service is around 400€. So I will live with it.
In order to find a slution, I'm looking for a bluetooth remote control something with same or similar functionality (check picture)

It's likely that you have a broken cable/connection in your clockspring, which is a flexible cable looped around a few times and 'coiled up' which allows the electrical signals to go from the stationary dash, to the rotating steering wheel. You should really get this fixed (or fix it yourself) since it could potentially result in your air bag not working correctly when required.
It's typically quite an easy replacement. You unplug the battery -ve terminal, then start removing things from the steering wheel until you can remove the entire steering wheel. At that point there would be a plastic box with connectors on both the top and bottom of it. You simply disconnect the connectors from the top, remove the old unit, disconnecting the connectors from the bottom whilst you do so.
Then when you install the new clockspring, you make sure it's at the mid-position, connect the bottom connector, screw it in, connect the top connector(s) and then reassemble the steering wheel. There are plenty of youtube videos for it.

Changing the ring ,at least for me, is not a easy issue, and the price of doing it professionally is more than 300€.
Such us airbag is not affected, I decided just to add bluetooth buttons, a cheaper but practice solution. Thanks a lot for all your advices, all of them have been welcome [emoji4]

https://cdn-images.xda-developers.c.../3/Canbus_Decoder_that_came_with_the_Unit.jpg
2. Is possible to use stering wheel in other apps than stock?
im interested in this as well. i have a 2016 mustang with MTCD_JY_V1.49_2 (Joying5.1) and want to do what you are asking. Got it from the US seller from Joying.

Thanks

This depend of your canbus decoder, in head unit factory settings / canbus, you can chose the type of canbus decoder, (this depend of your car model) some even let you control A/C and some setting of the car from the head unit, so the head unit it's capable but depend on the canbus decoder. For example for my VW head unit I can see Speed, RPM, Odometer, outside temp, fuel, battery volt, etc. but I can't control anything.

What car do you have? And what canbus decoder? My unit have the same vehicle info apk and show oil instead of fuel but this is only a translation error of the programmer and should be easy to mode.
Right now I don't have the stock apk I need to check on my home computer for the stock apk science I run a mode apk to match my car.

It's rare that doors info don't work science all other information show correctly maybe a faulty canbus decoder. I upload a picture of my decoder.
For the apk modifications I decompile the apk and mode in android studio. For canbus apk and for Vehicle info apk I made changes direct on the unit with apk editor (you can download from play store).

In the head unit settings do you test other canbus settings? I can't remember exactly how many for VW but I think at least 3 different.

I mode canbus apk and vehicleinfo apk just for the pictures of the car that originally show but the information it's the same from original apps. This apps work with the canbus decoder information received from the car ( in this case from canbus line of VW) I install this unit on a old VW bug and I replicate original messages ( from VW) and send information with teensy 3.1
Can someone please send me the vehicle info apk?

No DAB+ Signal

heyho,
i've bougth a official supported dab+ usb staff antenna for my radio.
after starting the stock dab+ app it says: connecting... now im plugging in the usb antenna it the app is ready (so far it seems the antenna is working).
but now, on the top left there is a signal bar with no green bars.
i've already tried some postions in my car (see photo ) and some other locations which are marked online as very good dab+ area but still no f*** signal.
i've already contacted the erisin support, they want me to send the unit back from china to europa (i have to pay for shipping, hahah...) and they will check the device... realy!?...

Youre sure it's a dab+ antenna ? For me it looks like a dvb-t external antenna.

Same Problem here.
I have the second unit and still the same problem.
I installed the Antenna as discribed in the manual, but it doesn't work.
Erisin said they tested all products bevor shipping, it must be an installation error from my side...
Hi all,
I have the same DAB+ box. It is not only an antenna. For me it looks like a complete receiver box for DAB+. It has to be installed before starting the app. Maybe before booting the head unit. I'm not 100% sure. But not afterwards.
BTW: I'm not happy with this tool. Fo me it doesn't make any sense to have a receiver box with a fixed connected antenna with a magnetic socket. How will you install this in a car? A connection for a separate car antenna would be much more better.
Kind regards

i already installed the antenna fix into my car. still no signal etc.
I have the same problem on two units.
- Erisin ES4046B with RK3188 and Android 5.1.1
- Erisin ES6046B with PX5 and Android 6.0.1
The application works, so the DAB + key is recognized but does not pick up the signal.
Does anyone have a solution to this problem?
Thank you.
im currently out of this issue.. i have sold my antenna..
i will order a 3rd party antenna with android driver.
I will post my feedback later this month

Works fine for me on 2018 Acura. Only issue, as referenced above, is if the notch is hidden, it cuts off the screen on the car's display.
Works fine in my [emoji176]Kia Rio 2018[emoji176]
Had to disable the notch hide... grrrr, works fine, not as snappy as my pixel 2 xl in android auto though, connected to 2018 Jeep
works fine on Chevy Volt 2017.
Yep is fine for me. Was tricky to initially pair but after I changed notch setting it worked. 2017 Mercedes.

Cool! I've never actually used Android Auto. (Mine's a much older system, so too prehistoric to have smart related stuff, but after seeing this, I'm now seriously thinking of upgrading). Does it give you access to all of the stuff on your android phone, or is it just basic stuff like syncing up music, etc?

Its a long-ish answer so just download the Android Auto app on your phone and see it in action. What you see on the phone running the app is what you see in the car (aside from integration with steering wheel buttons etc).
Work fine with Skoda Octavia 2018
It mostly works for me but I have to change the connection mode from USB charging to MPT every time I want to connect to my car. Otherwise, it won't detect the phone.
This is with a Honda Accord 2016. The car connection has the same issue with the OnePlus 3T but not with a Motorola phone that I tested.

Oh Ok, this sort of answers my question anyway. (so basically it's more of an app than a built-in full blown Android OS on a car stereo). In other words, limited features rather than a full OS.. Not alot of point for me then if that's all it does. (Mainly I would have used it for music and gps in the car, but I can already do that from my phone easily enough). But if it had been the whole Android OS that does literally everything my phone does, then that would have been totally worth it!
Thanks for the heads up though! What feature do you use yours for mostly?

Question NaviFly 7862 - Kia Rio 2013 - No Steering wheel control

Hello!
Hopefully someone can help me here.
I installed the NaviFly 7862 in my Rio 2013, and all works fine EXCEPT the steering wheel control.
As far as I know, I dont have a CAN decoder in my car. But whatever I try I cant get the steering wheel controls to work.
I might just be stupid as hell and missed something though.

Sorry my mistake.
It doesn't look like your car uses canbus for swc, and doesn't have canbus wires in the radio harness.
What does the navifly harness have connected to key1?
Kia Rio (2011-2017) MP3/CD Head Unit pinout diagram @ pinoutguide.com
Looks like it should be B4. Then you can map the buttons in the app.
B4Steering Wheel Remote ControlSteering Wheel switch pushed0.5V ~ 3V
https://www.aliexpress.com/item/1005002291499893.html
Assuming that's what you've bought, I wish they had a more detailed picture of the harness.
If B4 is unpopulated, maybe there's a stray/improper connection instead that you can borrow the lead from?
And from the listing:

Thanks for the reply, it is indeed this unit. Just different front.
I've made better pictures of the harness;
That would mean that KEY1 (Black) is connected to Ground.
Ground is spliced to b5. Which, according to the pinout is empty.
ok.. what's your b4 connected to? It looks like b4 is the brown wire, and you've got a black wire for b17 (swc ground).
looks like the navifly listing picture is very incorrect as far as main harness pinout. See this post instead: https://4pda.to/forum/index.php?showtopic=1000996&st=100#entry100193155
Even just comparing the color coding, it looks like navifly screwed up and reversed #7-ant cont and #8-key1.
If so, use a paper clip, thumbtack, pushpin, whatever to release the pin and swap them around. Might as well inspect the rest of the pinning..
Following that blue wire to the car end, it lines up properly with A18 remote power supply for antenna..
Hopefully no damage was done as a result

ok.. what's your b4 connected to? It looks like b4 is the brown wire, and you've got a black wire for b17 (swc ground).
looks like the navifly listing picture is very incorrect as far as main harness pinout. See this post instead: https://4pda.to/forum/index.php?showtopic=1000996&st=100#entry100193155

It indeed looks as of the blue and brown wire are swapped.
I also found the reason why I couldnt figure it out.
This is the image they provided for the pins;
They casually switched KEY1 and KEY2 with Battery GND and Battery 12v...
Gonna try and switch out the two cables later (Ant and Key1)

Thanks a lot, only your diagram is different than the other one. Now im even more in doubt xD Now the problem is that B4 in my car is unpopulated.. So I have no clue as how to connect my steering wheel controls now.
So I'm going to try that later. Hopefully it works.
EDIT: I think I found it. Navifly, and almost all online sources, have the diagram for mp3/radio. My old head unit was a nav screen and has the steering wheel controls at b5 in stead of 4.
I fixed it by moving B4 on the car side to B5. Steering wheel works properly now.
Thanks a lot for the help!

Glad to have been of help! Just curious; Is your audio balance correct? My phonecall audio comes from the back of the car. I'm guessing those cables are wrong on the head heading as well. But it's around freezing here, and to cold to sit on my car without heater hehe

Question Ford C-Max Android Unit - My Feedback and help request

Hi everyone,
so i've bought a new android unit for my car. I have been checking the other posts in this forum but they are kind of "pro level" so i felt the need to clarify some doubts. I know you guys are experts, if you can help be i would be thankful. I'll also provide some feedback that maybe can help people who are considering buying it.
The unit i've bought is this one:

I have a Ford Grand C-Max manufactured 11/2015 (the restyled one), and i thought this radio would be a good fit (i've had other android units in my past cars). I bought the 6G+128GB version (TS6 version), with Android 11. The brand is "Navifly", however i guess this is just another brand variation.
1) Feedback​
Positive​- Fast and fluid Android experience - no lag to complain about.
- Sound Quality - a great improvement over the Ford Sync 2 original radio - better definition, better bass, supports higher volumes without distortion
- Radio has RDS - it actually shows the station name (we don't have DAB in Portugal, it is still FM) and the tuning quality is good
- GPS is ok. Not awesome, but usable. Supposedly, it also gets some Glonass satellites, but as you know Glonass constellation is sparser, so it usually only gets GPS triangulation. I use Waze, sometimes it takes a bit to understand where it is.
Negative​- Quality of design and build of the plastic fairings: the plastic fairings are much lower quality relatively to the Ford ones. They don't precisely fit the car dashboard, by a couple of milimiters. I have it provisionally installed, but i'll have to shave some plastic when i get it definitely installed. Additionaly, the chines fairings don't have the metal clips/retainers that the original plastics have to get it securely in place. I've has to order some to get this sorted out...
- The CANBUS communication:
-> i am not getting any steering wheel communication at all (no volume control, no call pick up. This is the worst part for me
-> the information of the parking sensors is erratic. My car has 6 sensors at the front and 6 at the back (360º coverage) and there is quite an error on the info shown in this android unit, so i am not not trusting it a lot. Besides that, it is slow to react (couple of seconds), and the car should be drawn vertically (you brain needs to rotate the view 90º to get it right).
-> No Park Assist (automated parking) information is shown at the unit, so the Park assist is not currently working
-> I can get reversal signal, climate info (when i change it), and open door information.
- The screen. For its size, its low resolution, not bright enough, and it is very reflective. Not very happy with it.
​2) Help Request​I need help to sort the CANBUS limitations. This is the canbus box they sent me:
I guess this box is not the most adequate for my C-Max. I can't read chinese characters so i really don't know what it says at all. I've tried to get into the canbus box definitions in the settings menu and have tried selecting other canbus choices with no avail: i couldn't get steering wheel info at all. So i've went a bit overkill and ordered two canbus boxes to see if a different canbus box solve my issues. I've ordered these two:
- Another Hiworld box (i guess this is a newer version than the one i have, so i hope they have sorted out the issues) https://www.aliexpress.com/item/1005002718903038.html?spm=a2g0o.9042311.0.0.27424c4dac8EZc
- An XP one: https://www.aliexpress.com/item/1005002327630203.html?spm=a2g0o.9042311.0.0.27424c4dac8EZc
So i now have three questions for you guys:
1) Is this a FYT unit? Or a Mekede?
2) Will any of the new boxes sort out my canbus miscommunication?
3) Is there any place where i can get a firmware update? Or canbus firmware update? This is what the Android System settings show about my unit:
Thank you guys in advance for your help!!
I have tried other two canbus boxes from Hiworld and XP, with no avail. Still no steering wheel controls. Any suggestions?

Hi,
1) Mekede = FYT, not every FYT is a Mekede. But your unit is a Topways built unit sold by reseller TopNavi, so neither a Mekede nor a FYT nor a NaviFly. You are in the wrong sub-forum. Please ask in the general Android Head Units subforum
2) Ask your reseller TopNavi.
3) Please ask your TopNavi reseller or in the general Android Head Units subforum. There your will find the TSx series with firmwares and other information.
And by the way: It is a fake Android 11. It is still Android 10 (Api/SDK 29) as displayed on the web page. One can write a script that will set the "Android level" to any version you like: Android 10, 11, 31, 451, 10961, 4, ..
But it is a nice looking unit compared with the standard Ford units.
EDIT: This seems to be a FYT after all. Sorry for the confusion.
In my signature you find on the 3rd line the "HWGetInfo.apk". Please run it and share the created zip file.
