MTCD KGL PX5 - CanBus problem with VW Golf 6

Hi i've two problem with CanBus on Vw Golf 6.
1. If i open APP for steering weel config i can't see any button and i can't configure anything
2. Doors open/close don't work. I can see Temperature, Oil, RPM but doors doesn't work at all
I've this problem with my actual PX5 KGL and with my old RK3188 unit
Details of my actual unit:
Type KGL
MCU 2.47
ROM Malaysk PX5 2.0

1) car specific headunits which Steering wheel buttons control are based on Canbus Box CAN NOT BE MAPPED by the Steering Wheel APP. They are hardcoded to specific Headunit functions. There is a tool MTCDTools from @f1x that could help you to assign new functionalities to your SWC buttons.
2) I don't know why do you report it as a problem. It was promised to you that Doors Opening/Closing shall be working with the canbus box supplied? Each Can-Bus Box is capable to decode specific features of the car. If that functionality was not present on PX3 or PX5 is due to your can-bus CAN'T DECODE (or has not been programmed to decode) the open/close door system.
The CarSettings app just receive which functions are being decoded by your can-bus and show the decoded information received.

Can you point me to the location of the CarSettings app? I can't find it in my newly installed headunit. I couldn't find any in the Google play store.

I found a fix for you problem, capu81, you need to go to factory settings, Canbus and try to change the can bus setting with some other value. The can bus box has the ability to decode some dozen car types, and it's probably not set for your car properly. When this setting is done right the apps that everyone is looking for, the Car info and Car settings are going to be available and should contain all the old settings that were available on your factory head unit. The default password for accessing factory settings is usually 126.

And if the canbus decoder is not supporting your vw golf 6, then go to roadnavi and buy their CAN-bus Decoder and select the right model. Eg: RN Model: C257 Golf 7

Thank you to all for the answer.
The doors signal is not a big problem, l leave it in this way.
Steering Well remapping: with MTCD Tools i can create custom action. For example: i've button for MUTE. If i remap button with MTCD Tools and assign Vocal Google Search to it the action is fine but MTCD became MUTE. There is a way to disable factory action and use only MTCD Action?

I have this problem too (no mapping option) but my steering wheel works on my Ford Focus. Check your CAN Bus box and make sure the model of it matches what's selected in Factory Settings. My CAN Bus box is a Raise 06, likewise it is selected in Factory Settings to match it.

@capu81 I am having this same issue with my doors on my Erisin ES6405V. Currently emailing with Erisin back and forth trying to get this fixed. If there is ever an outcome, I will let you know.

I have same exact issue. Did you find a solution to it?

Hello, I have the exact same problem only the other way around, my steering wheel buttons are mapped and working, car is showing open/closed doors but for oil, rpm, speed battery nothing. I tryed messing with the canbus setup and change to other setting from VWto maybe get it to work but no luck. Any ideas on how I can solve this? I have a MTCD unit px3 2GB 7.1.2

I have also problem with CANBus decoder. The only problem is that when i drive and change shift activate rearview camera, all the other stuff (swc, door signals and also reverse enable the rear view camera) works fine. There is something like update or a settings that works fine. I have a FIAT Bravo model >2007 and in factory settings seems to be all ok

These are not "problems" - CAN Bus support depends on your car model, the manufacturer of the CAN Bus box and whether MTC/HCT have written the software for these things. If youve played araound with all the CAN Bus settings and not every function works then there is nothing you can do . . . apart from get hold of the CAN Bus protocol for your vehicle,, the MTCD MCU protocl and then write and app for it. There are 1000s and 1000s of cars on the market (and 1000s no longer made) it would be far too costly to make full CAN Bus support for EVERY car on sale, so only the most popular cars are supported and even then not all models and/or all functionality.
@j0nnymoe - dont waste your time contacting Erisin, they are a seller not a manufacturer and theres nothing they will be able to do.

@typos1 do you think maybe it can be fixed if I update the MCU to the latest version? It just seam strage for it to work in open/closed doors but not for the rest, I'm thinking maybe a mismatch of canbus and software and maybe that is why it dose not work. (Just a wild guess)

Updating the MCU may certainly help.

@typos1 that is good to know, I can keep my hopes high for a bit longer but I am sceptic about the MCU update [email protected] gave me.. He did not test it and there is nobody else I could find that updated to the latest version of XRC to confirm it is the right one.

What do you mean "the right one" ?

If you remember on the other thread, he just attached a dmcu file of the latest MCU for my XRC unit and said he did not tested it.

Yea I gave up on that a while ago. I've had a couple of these units before from other sellers (xtrons/eonon) and the canbus on those units worked fine. I suspect the KGL unit's doesn't like my car for some reason. I toyed with the idea of getting another canbus decoder..maybe if I can get one cheap enough I might try it.

I've got an a3 and I'm using a kgl unit and nothing shows on my dis screen on the dash but when I've had a unit from xtrons before that did work.. I'm guessing kgl must use cheaper canbus decoders and I've been thinking like you and we're thinking of buying another decoder from xtrons to try

MFD display in VW-group cars

Question for VW, Skoda and Seat owners: Is there anybody here who is able to get their MTCD unit to show things like radio station frequencies on the build in MFD display? I have a Skoda Yeti (technically similar to Golf VI) and I am not able to make my MTCD unit with Malaysk 4.0 show these things on the MFD. Previously I had a Ownice C500 and that unit was actually able to show a compass on the MFD. I have seen pictures on an russian forum from a guy who could see radio frequncies on his Seat MFD (I think it was from a MTCB unit) . I am looking for a hint as to what settings I need to change in the ECU with my VCDS equipment. Thank you in advance.

Kurt Lund

do you see anything on the MFD when using the original Bolero/Columbus/Amundsen?
If yes, then you don't need VCDS coding, the canbus adapter and MCU should do the job. I didn't try it on mine, i will do so later today and post results.
...and latest Malaysk is 11.5, not 4.0 btw

I never had an original radio which was able to send information to the display. I tried various setiings in VCDS to see if I could enable something, but to no avail. Thank you in advance for looking.

BTW: The latest ROM for MTCD HU with PX5 processor from Malaysk is 4.0. 11.5 is for older type of HU.

I have a SEAT Leon and a MTCD PX5. It only shows the radio station, but not the RDS info. If I use the music app or the bluetooth app the MFD only shows the number of the song but not the tags (name, artist, etc.) As I understand, it is something with the canbus.

a, ok i assumed u had a PX3

I have a 2010 GTI. Replaced the original radio with an MTCD.
Previously, my MFD would show compass direction (N, NE, E, SE, ect) next to the clock and I would also have a radio station section. After installing the MTCD, the compass would turn on, set to North, correct to the actual direction, then turn off again. It was a continuous 5 second cycle of this. I asked around on other forums and finally found that it just wouldn't work. One person just pulled out the compass unit. That's what I ended up doing. It doesn't bother me to not have it there if I'm just going to have navigation on my HU anyway.
For the radio, honestly, I never used the function on the MFD. It was easier to just cycle the presets using the steering wheel controls or pressing the button on the HU instead of changing to the radio function and scrolling through the list.

I agree it is not the worlds most important function, but it irritates me that I cant get it to work anyway. Your GTI from 2010 has exactely the same ECU as my Skoda as far as I know so it ought to work.
What do you mean by "just pulled out the compass unit"? Physically took something out?

Seems like there are always going to be little things you have to ignore when you go with non OEM electronics. I'm pretty picky about stuff, but I can let the radio go.
Yep, the compass module in my car is in the rear headliner. Just Googled it and found this video: https://www.youtube.com/watch?v=mw1T7oqiQsw

@Kurt Lund i checked on mine and in the "audio" menu it shows the FM frequency of the station playing (when in radio mode) and track# and mm:ss (when in default built-in music player mode). If i use poweramp it shows just "Video" input on the MFD, no track or counter info. I don't see a compass on the MFD since i didn't have an OEM navigation setup beforehand.

The compass on mine always showed up as just letters next to the time. So, the very top would have something like "NE 5:34" or "S 6:20". There was also a calibration option in the MFD setup menu. Selecting calibration would require you to drive in a circle. I also didn't have a factory nav unit.

Is there a fix to this yet ? I installed a MTCD unit on my vw touran 2006 and at first (1-2 days) the MFD displayed Audio but no information.. that was not a problem since I could atlist use the buttons on the steering wheel to change the songs anyway.. but afther that the Audio from MFD dissapeared and the onky way I can change the songs are from the HU. (compas also dissapeared).

If anyone is wondering, we can display on MFD using CanBus.
We can find adresses to write on internet: https://docs.google.com/spreadsheets/d/1eirT8LbSRl4j06BpwgsiE4PM_2BGH9UStdWLXwKvHJw
If someone is able to take info from android and send them through canbus you should display everything as original.
Here is a MFD compatible Head unit: http://m.cardvdstereos.com/android-8-0-car-dvd-player-vw-mqb-universal
If you ask for firmware of these unit you should maybe able to look how it works.

I looked at this. I had a windows CE head unit and that could display the MFD compass heading, so I know it should be possible with a non-VAG head unit. Looking at VCDS information it seems that compass information can be put onto canbus by either the head unit or a compass module. Cars without a VAG satnav such as the Columbus, would have a compass module instead, usually fitted in the top of the tailgate/boot/trunk.
So theoretically if you want the MFD compass and your MTCE head unit isn't putting the data on the canbus you could install a VAG compass module to do this. It would require VCDS coding to setup though; to register the compass module.
From what I've read it doesn't seem as if any MTCE head units put this compass data on the canbus; though there seems no reason why they shouldn't be able to do this. I would guess that it wouldn't even need a firmware mod, but could be managed in software.

Interesting links! I'm really looking for something like this as well, but not with Android 8.1
I'm wondering how they've implemented this in the software. Is it like a driver for a system app or just a normal app?
I'm a developer myself and I feel like I can add this myself. I'm not sure though if I can just send whatever data I want over canbus via Android? Would be great to write some software for all of the VAG users here that have an Android unit so their MFD are fully working again.
I'm thinking of: Fully working navigation with the compass and the instructions, full working media display (FM, DAB, BT).

That would be GREAT! I'm not a developer and an app like this would be awesome for me!
When I switched to Andorid unit instead of original unit, I completely lost any info from my unit to MFD: radio, compass, navigation, etc.

I unfortunately no longer have an Android unit in my car, so I would first have to find something for that and start programming on it. Is there any other interest in starting a project like this?

Mcu Problem / steeringwheel controls

Hi All
Thanks for any help you can give with this, i have been unable to find this problem mentioned elsewhere.
I have changed the mcu on my px3 1gb rk3188 head unit as i had been having trouble with the steering wheel controls being intermittent over the canbus.
I am sure my original was a kgl mcu but if i install that one and a few others i get a random beep every few seconds.
I have just tried the newest www and mx mcus and i also get the beep on these
The last mcu i had without the beep i think it was an mx one had no option for disabling the reversing camera
i was hoping to try hals nougat firmware however this requires a newish mcu.
Is there a fairly generic brand mcu which is likely to be a winner for me please or is there anything i can do to stop the random beeping please?
Also is there any way to make my steering wheel controls less intermittent please they will work fine for a while and then stop completely and same in the car diagnostics app so i assume it gets bored listening to the canbus and gives up.
it is a 2011 seat ibiza ecomotive.
Thanks
Kamcel

It could be the spring cable in the steering wheel if I understand correctly. My cable is going/intermittent but reprogrammed the buttons there are 2 sets for each button, I think it's a resistance issue, but it appears to be working for me.

CAN adapter - Help needed (Mercedes)

Hi All,
I need to find some info for the Can adapter so i can fix my issue and help other people with similar problems too .Owner of an MTCD PX5 unit, specific for Mercedes ML (W164) that came with the Can adapter.
From day one the steer wheel buttons worked (vol up/down, phone) and reverse camera out of the box BUT i had no vehicle info at all (door opened, fuel level, temperature, parking sensors etc) as many of the users especially on VW units have. The car is a 2010 model therefore the canbus info should be plenty. Tried all the combinations of CanBus under the extra settings with no luck.
One think i noticed is that i had NO Vehicle.apk or microntek apk and MTCCanbus.apk installed on the unit. I tried to install but installation was failing for both. Even copying to system/app/** didn't worked.
Any idea ?
BTW Anyone knows what is the Knob Mode under extra settings ? Mine is set to : 2 10k/20K ADC Ports
Details:
Unit: MTCD PX5
MCU: MTCE_GS_V3.00_3
ROM: Halk9 Mod 3.1 (Android 8)
Can Adapter : GS 10280514 / HW:V2 SW:V3
Can adapter Setting: 23 Benz_B200(simple)

Hi, i have the same car the same headunit and the same problem.
All is fine but i want to have more can-informations/functions.

Good to know that this is a generic issue and not specific to my unit and car. It seems a lot of people with Mercedes cars have similar problems. I wonder if this is related with the cheap implementation of the Chinese Can adapters or related with the car.
Will keep searching

Another thread is open with more technical details for similar issue, more HW oriented though here > https://forum.xda-developers.com/android-auto/mtcd-discussion-questions-development

I have the same car w164 and px5 android 8
The same problem.
No I have more problems the canbas stop working no reverse camera no Wheel key vol working and no led light on unit key, I think my canbus dead ?

Clock resets in the counter after waking up the radio - Mercedes W639 Viano

I bought an Android 10 4 / 64GB DSP radio, connected it, added cameras and everything works. I coded with Star Diagnose so that it would not take the time from the GPS and the only problem that appeared was the watch in the odometer was set to 01:07 after waking up the radio.
When I unplug the canbus decoder - clock does not reset. But I would like to have a canbus because it shows some extra features
- steering wheel control
- open door signaling
- radio sleep mode
- cameras in reverse gear etc.
I wrote to the seller, but only what the MCU update gave, but it didn't help.
I currently have
MCU version: MTCE_GS_V3.67_1
Build number: RK3368-userdebug 10 QQ2A.200305
I have questions for you and requests for comments
- Has anyone encountered such a problem?
- Is there a new version of the MCU that I can upload if so what?
- Is there a new build version
I'd like to try to update, it probably won't help, but it's always worth a try.
