Car malfunction after connecting RK3188 based head unit - MTCB Android Head Units Q&A

i got my new RK3188 based head unit 3 weeks ago (android 5.1), with CANBUS module to display varies car info in the unit and get the steering wheel controls working, last week my car displayed "Error: Transmission" (Skoda Octavia 2014), and my transmission box started to act weird (skipping gears).
First thing i did - was to remove the head unit, but the problem was still there, as my car is still under manufacturer warranty - i took it to repair shop (after installing the original head unit back), and got it back after four days - they said that the transmission computer has malfunctioned and they replaced it.
The nature of the problem (computer malfunction) and timing of it (two weeks after installing a head unit with CANBUS connectivity) got me worried - that maybe something with the head unit caused this problem.
has anyone every encountered this? can it even happen (is there any protection for such issues in the CANBUS protocol?)?

The problem with your transmission computer is completely unrelated.

Thanks!

front panel swap (eonon/kld) to kld2(???) ford to mitsubishi

2 years ago i bought a eonon unit for my ford focus (kd 7018) g616X rk3066 4.2 android. the unit was great and preformed well.
a year ago i bought another android unit but from ebay for mitsubishi outlander rk 3066 4.4. this unit had a faulty radio tuner that was poorly built. also, the reception was awful (on and off reception and need to on off the unit to hear properly)
i sold the ford car and was left with the good ford unit.
today i tried to find a solution for the tuner problem and all over sound problem in the outlander unit. i tried the dab and it worked ok, but i wanted the simplicity of the radio app. after reading a question here about switching screen i just got the outlander unit from the car and started to swap the screens.
i had much luck that the units probably came from the same assembly line but with different qc . so all i needed to do is chang two flat cables and change all the steel case between units.
after i changed the screens (and buttons and facia) it just worked!
i did not change the card with the processor and memory but to make the "face" fit i need to replace cd/case and dismantle all the unit.
weird thing was that the car symbol (ford) and (mitsubishi) "stayed" with the motherboard.
some pics:
You can change the car symbol go to factory settings and code is 126 and u can see car logos menu

BMW E90 Eonon GA7165a PX5 MCU Version MTCD_WWW_V2.58.1 dab interference

Hi,
I have a BMW E90 with a Eonon GA7165a PX5 userdebug 6.0.1 MXC89L with MCU Version MTCD_WWW_V2.58.1
I have the optional dab Adaptor they call V0054, it has a single USB cable out of it that plugs into the rear of the head unit and a DAB ariel that goes to the windscreen
this started back in April when I bought it maybe 50% of the stations had terrible interference and distortion on them no matter where i was whereas the remaining stations, (magic, xradio, chill.... ect were clear)
I logged it as a problem with Eonon support (which is dreadful btw) to which they told me that i needed a stronger active ariel so i left it until i got one in august,
I bought an active ariel and fitted it, and guess what exactly the same only stronger signal.
I have since discovered that the channels are only broken when the car is running and if the car isnt started every single channel is clear, and as soon as you crank the car over it distorts, and soon as you stop it, it clears back up again, below is my video of what happens, ignore the red light on the dash at the time of recording it, I needed new rear pads lol
https://youtu.be/X6GGmsABsfw
I logged it again as a problem and they this time tell me that i need a new dab adaptor and as it is beyond the 60 days warranty i will need to buy another adaptor. I can almost guarantee this isnt the case and its probbabily just interference from somewhere but i cannot eliminate it for love nor money.
any help is greatly appreciated

Help updating and fixing the wifi of a head unit

So i bought a car couple of days ago and the head unit works great except for wifi , it turns on but never finds any network , also the head unit version`s last update was in 2017,
I dont know much about head units but here is what i think can help: px3 , MTCD_WLGK_V2.58_1 , 7.1.2 Android
Any help will be very appreciated
Try to take a peek on the wifi cable connection to the motherboard.
I had a unit where the wifi ground cable was not soldered properly. The wifi range was pretty bad and connection broke after several minutes.
After resoldering it was fixed.

Canbus errors - Should I care ?

Hi Guys,
I have a Seicane PX5 octa core, 4GB RAM/32GB storage unit installed in my Mitsubishi L200 pickup. Had it for over a year now, and has worked perfectly from day 1, steering wheel keys all good, bluetooth calls, navigation, audio (much better than the stock radio), etc. Got a DAB+ box hooked up, reverse camera, etc. Really happy with it, upgraded to Android 10/latest MCU over the last week, again no problems.
So, why the post ?
There is one issue I had initially. The unit came with one of the can bus decoder boxes that connects to the loom at the back of the stereo. Once fitted and I started driving, I started getting all sorts of warning lights flashing on the dashboard - airbag warnings, engine lights, etc. Reading the OBD codes it was complaining about canbus communication errors. I cleared the codes and disconnected the canbus decoder from the loom. Ever since then, no codes, and the unit works perfectly - including things like the steering wheel controls.
So my question is, should I care that the canbus box caused errors ? Does it actually do anything worthwhile ? I guess it might depend on the vehicle it's installed in. Door Open warning maybe ? Speed sensitive volume adjust (although could use GPS for that) ? I'm just wondering if it's worth trying to get a replacement or just forget about it as it doesn't do much anyway.
Thanks.

scottydog, apologies for not replying to this sooner, I never got a notification that someone had replied to this, and I have had cause today to revisit this issue.
The head unit I wrote about was a Seicane unit. Aside from the can bus issue described, the unit has been flawless. My solution was to just omit the can bus box, the unit worked just fine, steering wheel keys, etc al worked perfectly so I just left it.
However, I decided for Christmas to upgrade the unit to a Dasaita PX 6 unit, it will be faster, has higher resolution screen, etc. This unit also came with a can bus decoder as part of the vehicle specific unit. So I fit it, and guess what - exactly the same as with the Seicane unit - weird dashboard warnings all over the place, airbag, traction control, etc.
So, I think, no problem, just ditch the can bus box. But there are two problems this time - (1) unlike the Seicane, the Dasaita unit won't power on unless the can bus box is connected, and (2) the Dasaita unit has an application pre-installed that allows tweaking of a lot of vehicle specific settings (headlamp on time, etc) that you used to be able to set with the factory head unit, and I'm guessing can bus connection will be needed to make those work.
So I would like to get to the bottom of this and get the unit working with the can bus unit in place. I've logged an issue on the Dasaita forum so we'll see what happens there. I don't think it's the can bus decoder, I can't believe two would display the same problem, I'm pretty sure it's the can bus settings in the Factory Settings of the unit - I can certainly make the problem worse by altering those, but I haven't found anything that makes it better !
I've attached an image showing the can bus settings on the device as I installed it. My car is a 2016 L200 UK version right hand drive, it's a Totan model that didn't have sat nav as new but does have steering wheel controls, etc.
Any ideas would be appreciated !
Thanks
hi guys,
I have the same problem with my Mitsubishi Lancer 2009.
I installed a android head unit over a year a go and didn't had any problems until recently when my ABS and ASC light start being on in my dashboard. The lights keep switching on and off at irregular intervals and when i put a car tester on it showed beside the ABS error code (C2116 code) other errors on airbags and engine immobilization, all related with that android unit, errors on car CAN line.
My car has an Rokford Fosgate amplifier from factory and the sound system doesn't work without the Canbus box installed, so ditching the canbus is not an option for me.
I also ordered a new canbus box from China and i will receive the package sometime in January. I'll keep you posted how it works with new one.
If you have any other information on this topic or you find something on line, I'm really interested since the android head unit is a big upgrade for my car and i will hate to come back to original radio.

PX5 Heating problems when canbus adapter is plugged

Hello,
First of all sorry for my bad english.
3 years ago i bought this very head unit https://www.amazon.fr/Wekuo-Android-8-0-Lecteur-2015-2016-2017-Autoradio-Bluetooth/dp/B07GH48P59
It's running latest Hal9K Android 9 version.
Since one year back i started using less times my car but i noticed that after a while of driving the speaker would sound weirdly, some coil whine out of the speakers directly, but i never try to solve the problem...
Some months ago i could only start the car, drive 5minand then a very very lound noise from the speakers...
I changed all 4 speakers to brand new Focal.
What is the problem ?? Actually i was testing everything out of the car using a PSU , even changed the thermal compound and add computer fan to my HU...
At first i wasn't able to start the UH with PSU, then i find out because CANBUS i had to hotwire the ACC wire so the HU will start, and it did...
It runs cold as winter..... (which is perfect, and even pluged some speakers and sound is perfect)
but when i plug it back to the car it gets hot even if nothing is being used... and i mean i only plugged it to car power, even speakers were not connected..
Car battery is brand new, same as the one before, (fiat original parts), car alternator is working fine, also the problem is present with engine off or on.
I really thing this is CANBUS related, but from where ? from the can bus little red box adapter ? something else from the car itself ? ? actually this is my second HU on this car, and the old one i was able to start it with PSU without bypass ACC from CANBUS
It's a Fiat Tipo from 2016, it's original radio was the uconnect 5. Should i try to connect everything together and perform a new proxy alignment using fiat multiecuscan ?
I am getting very angry because this situation, i hate driving and not having music lol
If i can't to anything i thing i will erase the canbus from the HU and just use ACC, but i will lose canbus and steering wheel buttons as well..
PS: i sent message to the HU seller (i don't expect any answer after 3 years) because 2 years ago i chose bad MCU file and had some problems but after hal9K helped me finding the original one (i think) but i had a few bugs at the time i don't remember now, but i don't think this is the problem but if ' could find the original file i could do that aswell..
And actually i want to update to android 10 from hal9K.. but first i need to solve this problem.
Someone already had this king of problem ??
Thank you in advance.
