About AF function in KD MCU - MTCD Android Head Units Q&A

Hello, i have a MTCD head unit with KD MCU version; i noticed AF doesn't work fine: it doesn't search a better frequency of same radio station. Anyone noticed the same problem?

About AF function
Same hardware (KD with vers. 1.81)
It happens Same with RDS.
Does it works for you??

RDS works fine. What's your issue?

Does not change the frecuency of an station while i make long trips (i want to hear allways the same radio station)

Same issue for me; with RDS I can see name station, but don't change frequency in long trips

people says in another post, with the new MCU for Joying devices fixes the RDS issues.
http://forum.xda-developers.com/showpost.php?p=68917375&postcount=434
That MCU is not yet compatible with our hardware (i think), let's wait (and hope) for a new one for our machines...

Very interesting, thanks.
Unfortunately, MCU are not interchangeable. We have to wait for an update

I want to re-up this thread:
My unit doesn't work properly: my HU doesn't change frequency when I make a long trip (so I lost broadcast)
Did anyone with KD MCU notice this AF issue?

Same here, KD MCU v1.82_2. I have the same problem since day one.
I use a double fakra din adapter to connect the radio to my car stock antenna.
The reception is not as good as it was with the stock radio and I experience this horrible AF problem. Whenever I leave town AF goes crazy, when signal gets weak it starts scanning frequencies and takes forever to find back the program or most of the time it keeps scanning and eventually will stop on a totally different radio station.
I want to try a new fakra din adapter, and maybe will try the JY MCU since it has been reported working on KD units.

AF is still not good?

Has anyone a solution ?
End 2020 and stil AF does not function properly, doesn't change frequency when I make a long trip.

Please go to settings 126 OTHER then change value radio from 20db to 40db
This help you after change AF work Perfekt

My AF on my dasaita doesn't work at all, it doesn't matter if I put it to 40db or any other value. Even an antenna amplifier does not help. Someone said that the newer mtce updates provide a fix, I have the newest version but still no AF. The problem seems that it doesn't search for a new frequency when TP is dropped..

seicane unit?

Not many manufacturers make head units to match my car, a 2004 C5, even less with the newer PX5 units. I did find this one,
https://www.seicane.com/android-199...mirror-link-backup-camera-dvr-obd2-dab-s32577
Anyone familiar with this brand? Do they make their own or repackage?
What 2004 C5 is? (I expected a Citroën C5)
the link you provided is for a 2004 Audi Series (A4, A3, A6)
I think the same Audi you linked is on Daasaita (HotAudio):

Audi C5 is the Volkswagon/Audi platform code,
https://en.wikipedia.org/wiki/Audi_A6#C5_.28Typ_4B.2C_1997.E2.80.932004.29
What I need is for the A6 only, not the A3 or the A4. The A3 and A4 both use a different size face plate. I need one for the A6 from those years specifically.
anyone have one of these Seicane units?
is there any reason to think it's any different than the other PX5 units as far as modding and firmware upgrades?
thanks!
Hello, yes I do have a unit bought by Seicane SELLER.
Seicane is just reseller and you will get all sorts of units built buy other MANUFACTURERS if you buy from them.
In my case I bought a unit for Subaru and found it to be an MTCD device built by Klyde (MCU manufacturer code: KLD).
So as of my current knowledge you won't really know what manufacturer built your unit until you check the system about screen for the real manufacturer. And as a result the devices are no different than the ones bought by any other reseller.
Don't buy from them, they have worse to NO service at all!
I have a broken (warranty) seicane unit, i am mailing with them now for 1,5 month to get instruction how to send back.
They give bull**** answers or ask bull**** questions to keep you waiting, after a while they stop responding.....
I advise do absolutely NOT BUY from them, just a worse and also expensive seller....

I know they are sellers and not manufactors, but have no idea who is the manufacturer.
But warranty is given by a seller, not a manufactor, they sell it as there own but give no support what so ever on it.
If you have a problem they simply ignore it and hope you stop complaining and so there problem is gone.
Please make sure if you buy from China that you chose a seller which does give support!
The problem with my unit is it does not turn of anymore.
When plugged in it directly boot up, also when acc is off, when acc is turned on and off agin it should turn off by ACC control through can-bus control.
It seems can-bus is not working properly anymore....
When i asked support i get the most stupid answers such as:
check the 12V acc wire is connected... DUH there is no 12V acc wire in my car, it is fully can-bus, also there is NO 12v acc wire in the connector of the radio!
This then i get 4 times to check!
Now i get 5 weeks (i contact them 3 times a week) that there engineers are checking the software, FIVE WEEKS !!!!!
I am now aprox 9 weeks contacting them how to solve this (the unit was when i first reported it under warranty, now it is out of warranty...)
I never buy/order from them again!
I hope no one does!

I know a lot of sellers have bad support. I m just trying to see if I can help.
The stereo will have pins for ACC even if the loom does not have wires, what ahv eyout ried so far ? Have you asked on here for help ?
The MCU type will tell you who makes your unit.

Yes thx for any help, but the problem is within the canbus decoder i believe.
It is a unit specific for a Mini cooper, it has besides the radio/android part also the dials for fuel, obd and other car control lights etc, these also do not work properly anymore.
This car section is also controlled by the can-bus part of the unit.
The android part itself works fine, it is the can-bus part which is not working properly anymore.
The MCU have the letter KGL in it, i have really no idea who is the 'real' manufactor, but i actually doubt the manufactor will help.

Yes, I know the type, it has a round screen. KGL are the manufacturer - Shenzhen Kai Ge Le.
In factory settings, how many options are there for your car, for Minis ?
You can list CAN Bus decoder by manufacturer, how many many are showing for Mini ?
I ask this because you may be able to sort things out by getting a new CAN Bus decoder.

Seicane = Bad Customer Service + Do nothing for you after the sale.
I purchased a Head Unit from them back in June 2018. The bluetooth module has never worked and after going around with them about it, they sent me a different module, not the Parrot BT module I purchased originally. Replacement of the BT module requires disasembly of the unit, de-solder old BT, solder new one, but the reason the BT did not work was that a few of the SMD resistors were damaged during build or soldering the BT module in. 3 months since purchase and still dont have a working unit. Now they want me to ship the unit back but I know they will void warrentee due to customer opening the unit (not the factory), and will claim I damaged the board attempting replacement. Oh, did I tell you they never told me the BT module was soldered onto the main board?? When they offered to ship a replacement BT I was under the impression it was a snap in module simular to how PC processors or flat cable connectors lock in. They knew, but dont want to deal with problems.
Remeber, they are only resellers, not the manufacturer. They all buy from the same manufacter for the most part. Good luck if you do get one that works as expected from them.

Hi typos1,
The spec for my unit as follows:-
Head Unit: Seicane s081988f
OS: Android 7.1.2 (Nougat)
CPU: Allwinner T8, 8-core Cortex-A7 @ 1.8GHz
Memory: 2GB DDR3 RAM, 16GB EMMC, 2xUSB2
Display: 9", 1024x600 capacitive
MCU Version: T8.3.19-23-10-E43101-171127
System Vers: V9.2.2_20171202.103838_TW2
Linux Kernel: 3.10.65 (20171129)
Security Patch Level: 2017-07-05, 7.1.2 (Nougat)
Issues still unresolved:
Microphone only works for phone calls, no android apps (no OK google)
Screen calibration slightly off by 0.5cm
Audio from AM / FM radio good, but Android apps (google maps, Spotify, youtube etc) audio louder from front left channel than all other channels
no root, unable to add some apps that I would like
Using AM / FM radio and waze, an alert in waze mutes AM / FM radio and it does not return. This doesn't happen in google Maps
When using google maps, something happens to the audio where it sounds like it changes the audio fade to front speakers more than rear speakers but when this happens the balance between left and right seems to be corrected resolving issue 3. System audio preferences for navigation set to use all 4 speakers but doesnt appear to be working
I suspect that there are other issues that I cant recall right now but whats listed above is enough to be unsatisfied with the product. The primary issues that I need resolved are the Microphone and the Audio being all over the place depending on what app is used. It just needs to be consistently balanced left to right, front to back right in the middle for all apps.
I am not against using an updated system ROM or MCU but I am not knowledgeable in this area and despite doing quite a bit of research I still havent figured out if there is a compatible release that I can apply to my unit, and frankly with all the time invested in research, forums, testing and trying to resolve issues with the re-seller I've got more important things to do with my time (work, family, hobbies)
Any assistance that can be provided would be greatly appreciated and rewarded.
cheers

I bought about 9 months ago, directly from Seicane a radio of 9 "android 8 PX5, 8 core 64 bit cortex A53, memory 3891 MB, MCU MTCE HF V2.86 May 28 2018, for a Subaru Forester, the integration and the connectors are excellent but the radio had problems with the bluetooth handled by google and when connecting the cell phone via usb Easyconected, it did not recognize the cell phone, I asked for support but the solution from them was simple, and it was still the same, at the end I found a firmware of Hal9k, I installed to the radio and with this all these problems were solved, the link is "https: //forum.xda -developers.com/android-auto/mtcd-software-development/rom-hal9k-rom-3-mtcd-e-head-units-t3847477 ", Seicane never respond very bad seller.

You have an Allwinner chipset (not Rockchip or Intel Sofia) and "MTCD" or "MTCE" does not appear in your MCU field, so you dont have an MTCD/E unit and are in the wrong forum, try the Android Headunits general forum.

Thanks Migcep !! I think you saved me. So little about the same unit I bought for my Forester. Glad you shared your info.

PX3, PX5 or other?

I have a MTCD GS (Xtrons) unit for my Audi (PF75ATTAR). This is a RK3188 unit with Android 5.1. I have installed Malaysk's latest 12.6 ROM for this however I expect this is the last ROM he will be releasing for this platform.
The unit is a bit slow, however the MicroG version of Malaysk's ROM speeds things up. But I still think its time for a replacement.
I am trying to decide on whether to get a PX3 or a PX5 based unit. Both seem to be popular and Malaysk has current ROMs for both. I like the idea of Android 7.1.
Just wondering whether anyone has had or has both currently and their experience/comparison?
Is it worth just replacing the SoM for a PX5 board since the actual head unit hardware is the same?

I'd say px5 with 4gb ram. If you can't find one then 2gb ram.
Because they are making an Android Oreo build for px5.

Try @Hal9k_'s ROM, use the microG settings, its easily the best and fastest RK3188/PX3 ROM.
Hes even made the Nougat ROM from the RK3188/PX3 Nougat SoMs work on the 1Gb version, although its not as fast as his Lollipop ROM and is just the standard Nougat ROM (rooted), made to work non Lolliop units, he is working on a custom Nougat version that will work on both 1Gb and 2Gb RK3188/PX3 units.
However, you could probably very easily remove gapps and replace with microG yourself to make it faster, theres a guide for doing it (to Lollipop units) in the forum, just removing about 5 apps and installing microG.
Of course a 2 or 4GB RK3368/PX5 will be faster and newer, but @Hal9k_'s ROM will give your old unit a new lease of life.
I can't recommend the px5 for the unstable rom and no improvement in an year.
I haven't tried the others (px3) but even slower hardware is better with stable software.
I'm also disappointed about the functionality in general, you can't set stay on without ignition and go to sleep after half an hour, there is no low voltage shutoff, the device drains the battery well below 10 Volts and goes in an reset loop at low voltages disturbing other can bus devices some till some failure. Switched off by power button still takes nearly full current.
Not a device to put in an car overall.

I decided on a PX5 board with 32GB ROM 2GB RAM which took only a couple of weeks to arrive from China (Witson) and its working fine in my MTCD(now E) GS unit. The hardware behaviour is exactly the same as it was with the PX3 board (which I would expect as I haven't changed the MTCE hardware). The unit powers off with no ignition (as it did previously which I don't see as an issue?) and I don't have battery drain. I can only think you have it wired wrong or you have faulty hardware?
I installed Malaysk's 6.2 ROM and have installed my own apps and its all good. I have issues with the integration with the car (CANBUS) but these are exactly the same as they were with the PX3 - I don't think anything but new firmware for CANBUS decoder will fix these issues.

Here I tend to partially agree. However Android 8 might be available as custom ROM on PX5/2GB/4GB units soon. There are official Android 8 preinstalled PX5/4GB boards available already but it's still not clear whether we can upgrade PX5 2GB SoM and the PX5 4GB SoM which were shipped with Android 6. Probably this will be sorted out soon.
What kind of instabilities are you referring to in particular?
I am asking since my PX5 with stock KLD ROM from November 2017 is quite stable. At least no app crashes and similar issues. Despite the famous Google Maps hanging which seem to be mainly related to Google Maps code itself and there is a work-around for it.

Not sure what would cause this. My unit enters standby immediately after ignition is off. Then it kills all applications to avoid any background process waking the device (which is btw. the root cause for some app issues). In Standby mode my device draws very little power. I didn't have a single issue even after the unit being on standby for more than a week when the car was not in use. If concerned you might connect a battery watchdog in between the unit and the car so when voltage drops below a certain treshold it would cut-off the head unit from power.
If the unit would have such a battery watchdog implemented that would of course be great but I guess the units were built to keep a certain price range and in most cases such a watchdog is not required.
Though I understood that some cars do not have an ignition trigger any more but get their power-on signal on canbus. Here I could imagine that the canbus adapter perhaps need additional power to listen to canbus wakeup events. Not sure about this scenario though as my car has an ignition cable connected to the head unit.
I fully agree to the "unable to turn on when ignition is off" issue. This is usually possible with factory head units but MTCD/MTCE units seem to be mostly unable to be powered on without ignition. The only work-around I can currently imagine is to mount a switch which shorts battery+ to ignition input on the head unit which would allow you to manually power it up. Also such a switch can be combined with a small electronic timer. So it would be medium difficulty to mount a button which pulls on the ignition line on the head unit to 12V for 30 minutes and then resets. Still a pity it's not built in I agree.

You ignition/sleep problems will be down to your car and/or the CAN Bus decoder, not the stereo, as will whether the unit can be powered on or off with the ignition on.
I ve not heard of anyone saying the ROM is "unstable" before. In fact I ve not heard of any of your problems before, only the GPS bug and the BT/mic probs which you dont mention.
It sounds to me like your stereo has not been installed properly.
Many are just lacking deeper technical knowledge to see that problems I have investigated.
Or try to fix it with cooling fans.
I have a original mercedes radio having the missing features it is just a matter of proper engineering.
Yes it is not android computer I would like to have but not crashing every hour and at the end the car distracted by.

Good morning all ,
my px6 car radio continues to have random crashes especially a few minutes after starting the car, the seller does not answer me anymore,
I tried various roms, the problem is still there, suddenly I'm staying on the rom halk 9, I check the wiring, everything is good, after it has frozen 1 or 2 times, I can roll 2 non stop time the problem will reappear only during the next start the next day, my mcu version is (MTCE_MX_v3.41_1 15 nov2019), I can't find anything on a possible update or demotion of this mcu, would you have any tracks to study? thank you

Do you have a hammer. Return under warranty or replace SOM might be the best option.
You're looking for someone reading these forums to guess what the issue is with your unit. It is unlikely a software issue and apparently unable to work at a hardware level.
Had the same issue with mine a PX30 unit with MTCE MCU version.
Turned out that the Canbus is rejecting the unit.
I have a Opel Corsa D. Astra H have the same issue.
If you have steering wheel integration, you have to connect the CanBus Decoder to a seperate 12v connecting like cigarette lighter.
Preferably also the power to the unit itself (not when Canbus Decoder is feeding it).
Both CanBus Decoder and Head unit must be not be powered when carkey is removed.

Did you try pushing the RST button until the panel buttons flash?
If not then do that and as soon they flash, release the button and press it again for a short time.
Then you will be set into the recovery mode. There you can reset the unit. Seems that the bootloader is faulty.

Pumpkin is just a reseller and has different manufacturer. they just stick their label on it.
Each manufaturer has its own way to get into the recovery... if they have one.
You may send us the link to the unit you bought, may be one can determine what unit we are talking about.

This is one of the units, only Pumpkin and the reseller can give further information if you don´t know the MCU version.
If you have it on hand... may be we can find something.
May be... Pumpkin AA0571B-B01 / PX6 - 4GB Ram/64GB Rom / Android 10 / rk3399 MCU MTCE_HT_V3.60_
That means you should post your request in the right forum: https://forum.xda-developers.com/f/mtcd-software-development.7379/
But first... I would contact Pumpkin or the reseller for a firmware.
If that doesn´t help, you may have a look at the Hal9k firmware.

I already reported your thread to get moved into https://forum.xda-developers.com/f/mtcd-software-development.7379/ That´s for sure the better place.

I tried to write them, but they don't respond for me, that's why am looking for help here. And the problem is how to get in the recovery mode or how turn on that thing
If you don´t get response... go the way written in the Hal9k thread I already linked. May be a good start would be to create a bootable SD card with Android 10.... but honestly: This is not the right place here. That´s the reason I reported this thread to be moved into the right place.

Question Which UIS7862 unit should I buy?

Im looking to get a new head unit for my car (Corsa D 1.2 2009), and was planning on getting the Teyes CC3. I then found out through this forum and elsewhere that its essentially just being resold? I then found other units like the Mekede M6 Pro, etc. Im not sure which one to get, does anyone have any suggestions? Or information that can help me decide between all of the UIS7862 out there?
Im leaning towards the Teyes even if it is slightly more expensive, as ive heard good things about their support and firmware updates.
But ive seen units for £180 (6+128gb) with better spec than the teyes at £250 (3+32gb)!
I mainly want good audio (so a good DSP and AMP chip), and i want polished looking software and not having to deal with the android stock menus as much.
For someone in the UK, what are peoples suggestions?
Thanks
Gershy13
Mekede M6 Pro (Youtube, another UK guy like you). Personally I would never buy a T'eyes. Too much closed source and paid software.

Thanks,
Would you be able to tell me what the main differences between going with teyes and their closed apps (some examples of why theyre worse) compared to something that isnt locked down? Like mekede or anything else.
Another one i found is OSSURET? I was thinking of the S8

It seems to have a slightly higher clocked processor too. And for the same price as the mekede i can get maxed storage and ram. Thoughts?
Are you planning to listen to FM radio? If you are I advise you to stay away from any FYT based head unit. If not go ahead.

Curious as to why? But no never planning on using the radio. (Spotify only)
AF function (changing frequency of radio station when signal gets too weak to a stronger signal) doesn't work on FYT head-units. If you're in a country that doesn't use DAB this should be a deal breaker.
Wish I knew that before ordering mine, but I didn't even know it was an FYT head unit. xD
Also be aware that the Bluetooth pairing functionality is quite unintuitive to work if you plan to share data via bluetooth from your smartphone. It does not connect automatically so you need to connect manually every time.

Ahh okay thanks. That's fine I don't mind using WiFi for internet sharing. Or even usb if it's supported.
And yeah no plans to use the radio so we're good.

are you sure about that, have you tried https://forum.xda-developers.com/t/...nd-sc9853i-fyt-devices.4387965/#post-86251871
Also, the BLuetooth on these units, comparatively, is very good, with proper BLE support via dual Bluetooth to support things like radar detectors (Valentine One.)

Yes, I am sure. Go over the thread and Kotix explains it why he can't fix AF.
He made a work around for an user to easily switch between saved frequencies of the same radio station. But this is manual switching that an user needs to do by himself, not automated. This is not optimal when you're driving.

My Bluetooth connects immediately every time I enter the car.
I also find FM radio to be excellent using NavRadio+
AF isn't a deal breaker for me. I only have 1 station that jumps between frequencies occasionally (BBC Radio 2) and Kotix workaround is intuitive and easy to use.
The fact that it doesn't affect doesn't mean the issue isn't there.
Bluetooth works well. Bluetooth 2 doesn't. There's the simple work around of automating an wifi hot spot when your phone connects to Bluetooth.
It's true the NavRadio+ is a big improvement but the AF doesn't work at all.
My bluetooth always connects to phone 1 but if you have phone 2 it will not link to it, you have to pair it manually even if it has been conected previously. That's a shame.

Same here - second phone never connects automatically. Really annoys me because we are two daily users of the car :/
Yeah, I know your pain lol. I suppose the manufacter would need to invest on a better bluetooth chip for two phones to work. I come from a Pioneer with bluetooth from 2008 and it already allowed to pair 2 distint phones at the SAME time!!! And it still works.

A recent thread addressed this and a reseller replied with a config.txt that seemingly results in the Bluetooth trying the last phone used and failing that trying the next phone in the list.
Does Bluetooth only reconnect to the last device used?
My unit allowed me to pair multiple phones (my wife and daughter also drive) but the Bluetooth system would only reconnect to the last phone used. So if I drove the car last, and then my wife drives, it won't connect to her phone without manually...
forum.xda-developers.com
I can see a few lines that might be relevant but I've no idea what the secret sauce is to change the behaviour.
Backup your current config.txt and give a few of them a try if you're confident.
Lines I can see that "might" relate to Bluetooth pairing...
ro.build.go_lasttop=true
sys.fyt.bluetooth_show_voice=true
persist.btpair.ssp=1
persist.fyt.enablebtvoice=true
persist.btautoconnect.count=3

Hum... thats interesting stuff. Thanks. I'll do a little more digging and give it a try if I discard the chance of bricking something.
