Hi everybody
Is possible config microphone in hu px3?
In this video:
the user accesses to menu "enginner mode" and config microphone.
Any help please?
Thanks
It's not an MTCD unit in video. Is your unit MTCD type

Hi MTCD community.
Thanks to the time between the years (that's how we call December 27th to 31st in Germany), I had time to upgrade my HU. Up to now I had a RK3188 quad-A9 one (Erisin ES2508B, KGL) that had a proprietary power connector and a external canbus decoder box. (more information here: http://vi.vipr.ebaydesc.com/ws/eBay...descgauge=1&cspheader=1&oneClk=1&secureDesc=0 )
That external canbus decoder of the unit has a few dedicated output pins for illumination, reverse gear and a UART (?) style digital RX/TX connection to send wheel-button key commands. It's a perfect example for a Chinese product. This solution it easy and works - almost:
On Mercedes cars the wheel-buttons are used to steer the so called Kombi (KI). KI and HU are connected via canbus. Key commands are send in one specific can-message. The canbus decoder box is said being made specifically for Mercedes cars. While it correctly decodes button presses it fails to decode the current KI menu. As a result the HU will always interpret the "prev./next" buttons, even when you're not in the KI's Audio menu. As a result you either stop using your KI (bad option) or you disable some keys in the HU (that's what I did). The decoder box is also only reading the canbus and thus not able to send audio titles or the current radio frequency/station name to the KI.
Because of the decoder box sitting between HU and KI I never tried to enhance functionality because that would have ment either connecting another R/W canbus dongle to the HU or replacing the chinese decoder box and reverse engineering the RX/TX communication between decoder box and HU.

The newer PX5 unit that I now own (Erisin ES7689C, KGL?/LM?, http://www.ebay.co.uk/itm/Android-8...s-W203-W209-/123151147422?hash=item1cac61619e ) has a Quadlock connector (that's the correct name for the multi pin connector that became popular on HUs beginning in the early 2000th) and no external canbus decoder box (it is indeed perfectly plug'n'play). It is also able to identify itself to the KI as Radio which means it is also writing to the canbus. Compared to an original OEM HU, information is still extremely limited and it again fails to interpret only wheel-button commands send from the KI's Audio menu. - But, it is able to write to the canbus, so potentially this is a much better starting point for enhancements.
Now the key question: Does anyone know how the HU is communicating with the canbus? Is the decoder box just inside the HU's housing (and again being an extra translation module) or is it a proper canbus device controlled by an app or service from inside the HUs android?
Good piece of info mate. Thanks a lot
Unfortunately i am not able to answer the question due to limited knowledge.
I own a Mercedes w164 and have the same issues and i am keen to find a solution. Open a thread for that too here > https://forum.xda-developers.com/an...t/adapter-help-mercedes-t3903165#post79005544
My MTCD idetails are :

Hi I also have a MB lol, a w203.
I have been through several head units of types makes etc, so know exactly what you mean. Although I never heard of 'ki' before.
My latest unit I have is def very good (best was a pioneer with separate car-pi can decoder) and that is also an erisin.
Great minds an all that eh!
The unit I have is a 4/32gb android 8. MTCE. It was working very well until I developed a problem with my reverse camera signal not getting picked up. Was switching OK but no image??
Anyway I bit the bullet and installed the custom rom by Malaysk which helps the camera but no steering control (for me) on 3rd party apps.
There is some talk about mtce files etc but I couldnt get anything to work until I installed a brilliant prog called mtcdtools (free from github).
Very techy to understand / use but with the info and help from others managed to replicate enough to get the two up/down left buttons working perfectly on all apps. It starts up by itself and stays in background. I'm very pleased with result and sure it could do much more if i only knew how. Def give it a go.
Also the up/downs only while in the audio sub menu and they operate whichever music app is running even while in the background if that makes sense. The right volume buttons always worked anyway, and with the phone.
I think the real challenge now will be getting info in the dash display to correspond with what ever app is on top. Currently mine just says audio off when using dab, but displays station number in radio and time elapsed from music player., but nothing from nav.
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

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 ?
On My Dasaita px6 Max HA2137B head unit
I'd like to bind the BAND button to my DAB+ app instead of the FM radio!
Can anyone please tell me how to do this Please?
Thank's

Hello. I fixed the damaged radio by replacing the PX5 module. The radio has started working, however the sound is only from the radio and bluetooth. No sound from USB, internet, navigation - displaying correct. I don't have an amplifier in my car. The radio comes with a CANBUS but I have a version of the car without CANBUS. Could this cause a problem with the sound? Please help.
You are in the wrong Forum. This is for FYT Head Units and you have an MTCD Head Unit. There is a forum for that where you will find the right people.
But anyway, did your unit used to have a PX5 and you replaced it by another PX5? Audio selection and processing happens a the Motherboard (the MTCD). There, the chip in charge of Sound source selection and processing selects from Bluetooth Chip, Radio Chip, and the PX5 (that generates any App-sourced sound like Navigation and MP3 playing). For some reason either the motherboard does not like your PX5 (faulty?) or there is some misconfiguration at the Android Level and PX5 is not reproducing sounds.
Have you changed anything on the Factory Settings?
But definitely your problem is not at the Canbus, but either at Android Config, PX5, or how the MTCD is communicating with the PX5
Thank you very much for the information, I'm new here so I'm still lost. I will move the topic to the appropriate forum. Thank you.
Hi, post system info, mcu version.

It's not an MTCD unit, search forums for CSN2
Hello all!
I have an Android head unit in front of me.
Unfortunately, the RCA PreOut are broken. That is, one output hums (Sub-PreOut), the others (FL/FR/RR/RL) noise.
With the Sub-PreOut it sounds like a ground loop; but it is not. I can completely rule that out through numerous tests.
Where are the RCAs connected in Android hedunits? I suspect the RCA preamp is broken.
I have a DSP module installed from the factory, which in turn is connected to some sort of switch.
I have already unscrewed the radio and traced the traces, but could not see where exactly the RCA outputs are connected.
Do they connect to the DSP?
The following hardware is installed:
CPU: Rockchip PX6 3399
DSP: "ADAU1401A-6CH-V01 HCT-DSP"
Switch for DSP: "SGM6510 YTS28 1345C"
I hope you guys know a solution
Is it MTCD type device, post MCU version and Android system information
Sorry for the late feedback.
I have only now seen your answer.
The following MCU is installed there:
MCU-Version: "MTCE_TONE_V3.78_3"
Android: "Android 10
CPU: "Rockchip PX6 3399"
