Hi all, new guy here with some problems.
I've bought a new headunit to replace my factory Skoda Stream Radio CD.
My car is an Skoda Octavia mk2 vRS year 2007, so any VW headunit should be OK in my car.
New headunit is a Joying Android 4.4.4 RK3188 with latest official firmware (June 2015).
I was trying to install it this morning for the first time and found several problems.
The most important one is the headunit doesn't power off even with my car completely shutdown and closed.
Headunit install instructions state there are two different methods to connect the headunit.
First and preferred one is using CANBUS decoder box, so headunit power is controlled through CANBUS decoder.
But if headunit doesn't power on when you turn on the car (that's happening to mine), you have to use second method: unplug CANBUS decoder box and connect ACC +12V red wires so that headunit gets powered.
With this second method the headunit starts up OK, but when i turn off the engine, take out the key or even close the car with remote control, headunit doesn't power off at all. I even tried to wait for 20 minutes but with no results. So i had to remove new headunit from the car to avoid battery drain...
I have upgraded firmware from Abril to June version so i got a new feature that allows to delay shutdown after ACC is off.
I set it to 30 seconds delay but still nothing. Headunit stays on.
I already asked to seller, and i'm waiting for an answer. But i thought maybe i could get some valuable ideas here at the forum.
Still don't understand why headunit is not powering on with CANBUS decoder connected. My car should support it, my factory Skoda Stream Radio CD is able to show climatronic info on display.
Other problems i found:
- Headunit buttons don't light even if i turn on car headlights. If i set button's colour in Settings\Elements buttons light for a pair of seconds to show new color, but then they go off again.
- I wanted to set Skoda logo at boot at Factory Settings but asks for a pin/password. Thought it was 126 but it isn't. What is the pin for Factory Settings?
- There's a slight buzzing coming from speakers when i turn on car headlights. That buzzing is not there with Skoda factory radio unit.
Long post, thanks in advance for your answers. :good:
Seems to me wrong or defected harness?
Does your car have factory amplifier? I had one that was making lot of issues. I figured out that the harness was the problem because they sent me a harness that is compatible with my factory head unit. But my car was standard trim that didnt include it. I had to cut one wire they told me to cut it. And it worked fine after that.

Thanks for your answer Scorbion,
Seller is going to send me a new Canbus box decoder. We think it must be faulty, that's why headunit doesn't power on or power off with it. Without Canbus box, ACC coming from VW harness is not a real ACC but a +12V to battery, because VW factory radio does all through canbus, and so headunit is always connected and doesn't power off.
Will update info when i get the new canbus box from seller.
Thanks

i have the same problem. can u fix it?
Did you solve this canbus problem?
Yes, new can bus decoder did the trick.
Long time ago though...
Hardware solution trumps everything
Had the same issue. Im also waiting for the supplier to respond. In the meantime, I just pulled the acc pin off the box and connected the radio to cig. lighter possitive. Works.
Hi
My auto radio version is:
px3-userdebug 7.1.2 NHG47L eng.hct20180
MTCE_XRC_V2.80_1
2Gb/ 16Gb
https://es.aliexpress.com/item/Isud...452.html?spm=a2g0s.9042311.0.0.215563c05GDxho
My Car: Alfa Romeo 159
Since a month ago, I´m trying to resolve my problem. Only 50% buttons swc are working:
My android radio has canbus box. I have accessed and configured canbus in "factory settings tap" but my problem continue ( by default canbus wasn´t configured ).
The app to remap the buttons does not detect any button on the steering wheel, it only shows "Reset" and "Save" but I can not do anything with it.
I have reading a lot of post... Is possible that I need to connect wire Key1 and wire Key2? How should I connect "key1" and "key2"? Could it be the solution?
Any kind of help is welcome. Thank you very much

Check that allí connectors from/to canbus and to the headunit are well connected (sometimes they require some force press to really be plugged)
On the link you provided there is a guy that commented that everything worked as expected including the SWC so....if you can't fix it contact your seller for support

On 1st photo the 3 "red" buttons are only working with the "original" factory installed "blue&Me" equipment, no other hardware can use or decode them.
On 2nd photo the 2 "red" button are only working with the original factory installed "blue&Me" equipment ad use to switch information on Factory Magneti Marelli multimedia/navigation unit during calls, with standard "simply" Alfa Romeo car stereo they are only working on charging disc from official CD Charger; no other hardware can use or decode them.
On some cases "non standard hard coded manufacturer swc" have funny responses; in my case Voice command button open the app carousel in my HU and the Open/close a phone call button activate the Mute function.
Check you Alfa Romeo Use and Maintenance Guide and Blue&Me User manual thaere was all the info provided by me.
So the other SWC are working like expected!

On 1st photo: I agree with you. My alfa romeo is a car of 2007 and it hasn´t blue&me installed. I did not know if I could use these buttons with the new radio
On 2nd photo: The buttons were working with my original radio. I could change the memorized radio programs. I've seen in some YouTube video, how this function is still operational with the android radio car and I would like use its.
Thank you very much for your help

Try long pressing the ones for "skip tracks/seek radio stations". My units acts like this. Try also all "Alfa Romes" canbus entries on Factory Settings

Hi!!
My Alfa 159 works like yours, only 4 buttons are working. I had one unit android 5.1 before the 7.1.2 and everything from swc work.
If you have the solution please MP

The seller send me a rom update, but I don´t sure to update the radio... Will it solve the problem or will it further damage it...
I can send you the rom if yo want it

I dont think it will make any difference, there is a way that MTCDTools can remap SWC on cars with CAN Bus, @ikerg can tell you how to do it or what thread its in.

Found said posts and they were for car which communicate with resistive signals via canbus (or something ), so wiring the canbus from car harness directly to key1/2 gives access to the buttons.
If Alfa uses no resistive signals, you wont get away with this.
GM cars like mine have the buttons via hardcoded addresses via canbus and you can only try to find those codes in android or mod MCU profile it seems... too nub to do so in my case.. trying hard

Theyre not the posts I was talking about - pretty certain theres a way to programme CAN Bus SWC.
Alfa 159s have CAN Bus SWC.
I've had a similar problem with my Alfa 159 when I installed a PX3 unit. However, for me all the SWC buttons except the centre button on the left set work (i.e. pic 1) and only the left and right SWC buttons on the right set (i.e. pic 2). It is weird as the buttons that do not work mimic the other buttons for some reason so it's like crossing of signals or decoding it wrong.
As I didn't find anyone else having a problem I assumed it was either the CAN bus decoder (I opened it up and flipped switch 4 which helped I think but maybe it isn't suitable?) or the connection behind the steering wheel is loose. I haven't got round to checking the connection (apparently it's simple to open) as I can still control most things.
BTW, my car had the blue&me installed from factory.
SWC on Alfa Romeo 159
H all, I just installed a new Android head unit in my Alfa Romeo 159 SW (2006) and all the SWC's work and I can map them from the app. Below I will explain how I did it, hope this will help.
My head unit:
Xtrons TE706PL
PX 5 octacore 4GB 32BG Android 8
My car:
Alfa Romeo 159 SW
Upgraded from original radio (so not the navigation unit)
My car did not have Blue&Me
Required hardware:
Dedicated CANBUS adapter
Connect2 (company that make it) CTSAR002.2 (product number)
Patch lead to go with canbus adapter
Connect2 (company that make it) CTMULTILEAD.2 (product number)
I ordered both from Amazon Germany from seller NIQ. The patch lead was included with the CANBUS adapter, just make sure to select the correct one meant for Chinese head units. Price was 60 euros.
Installation
The CANBUS adapter is connected between the original car connections and the head unit. This looks confusing at first (it has connections on three sides), but in the end everything only fits one way. On one side connect the patch lead, on the other side it is connected to the head unit and on the last side it is connected to the original car plugs. All these connections are very simple with plugs that only fit one way. (I did need quite some force to push in the 2 of the 3 original plugs into the CANBUS adapter)
As mentioned, the patch lead is connected to the CANBUS adapter on one side. On the other side you need to connect it to the KEY 1, KEY 2 and GROUND wire coming from the head unit. This was the only connection that is not made with plugs, so either crimp them together (which I did, very simple, but you need a crimping tool), solder them, or make another good wire to wire connection.
Important notes:
The connection need to be made in a specific order!
First connect KEY 1, KEY 2 and GRND wires
Second connect the CANBUS adapter to the head unit
Last step is to connect the CANBUS adapter to the car connections
My car did not have Blue&Me, so I don't know if this changes anything. I think I read somewhere you can just leave it in the car and not connect it. But maybe do a little research.
All this is also specified in the manuals provided with the products. Connects2 has some nice youtube videos on the CANBUS adapters, just google them.
I did quite some research myself before I figured it out, but now all is installed and working perfectly! I reprogrammed all the keys to my own preferences, including google assistant speech activation button.
Hope this helps!

Thanks for the info, but what unit do you have ? - "TE706PL" is a made up name, your MCU will tell us what unit it is, I m guessing a GS ?

I have a PX5 and have the same issue.
I see people talking about their chinesses mtcd/e read all the can protocols (open doors, all the swc, radio info to main pannel...)
Talking to my seller, he told me that may be the can decoder. Offers me a refund but I want one that works 100%.
¿Someone have the full functional decoder?

More likely that its just not supported, some cars have even less support.

That's what Im trying to find, a canbus decoder with more options.
I had the alfa 159 android 5.1 unit and It shows temperature, doors and full keys function. I upgraded to a new unit android 7.1 and now I haven't temperature, doors and only half of keys are working.
I recently installed a Xtrons PQS90MTVL head unit in a skoda superb. I have a couple of questions on how to get it to work correctly when navigating.
1) It seems that you can set the navigation sounds to be a percentage of the radio volume but cannot set it to play at a given volume regardless. The problem is that the radio seems to be constantly on and there is no way to turn it off. The 'on/off' button simply mutes the radio - and the navigation sounds.
Often I am in an area where I cannot pick up a decent radio signal on the programme I want and just get static. In these situations I want to turn the radio off but still hear navigation sounds. I don't want to listen to loud static just so I can have the nav sounds play at a percentage of that static. Is there a way to turn the radio off but still get navigation sounds? (a workaround I have found is to play a media file instead of the radio and then pause playback. The nav sounds are then still a percentage of the - non existent - playback volume. However this should not be necessary)
2) It also seems that a Internet connection is needed for any navigation. even google maps won't do a search without it as it says I am offline. (is this true?)
I have bought the 4G wifi dongle but have a question about its use. Does the HU connect to the dongle, as far as data is concerned, via the USB socket that comes out of the back of the unit or is that socket simply powering the dongle and the HUI is actually connecting to it over wifi using the dongle as a hotspot? If so then I don't have to use the wired usb socket from the unit (which I suspect is underpowered) and can plug the dongle into an ordinary 2A USB socket that I have in the car, positioning the dongle near the roof for a better signal
Incidentally I did try using Android Auto with my phone using wired connection. That seems sort of OK but is not very reliable. Often when starting the car it hangs at the 'connected' screen, or even at the 'trying to connect' screen, although other times it seems OK
3) There is a small socket on the left hand side of the HU that looks like a slot for a small memory card or a sim card. It is labelled 'GPS'. What is that socket used for? it is not mentioned in the manual as far as I can see. - The manual is generally a bit hand waving though, excitedly telling you what you can do but not how to do it.
(I did try the xtrons forum but not only are the last posts there around January 2022 but there seems to be no way to register for it. Hence posting here)

All I know is the model is Xtrons PQS90MTVL so maybe its MTVL (whatever that is) I'm afraid I don't know what mcu means so cannot offer any version for it. Its possible I have posted this in the wrong section and have rep[osted in 'Android Head-Units'. If that is the right place and this is the wrong place, please can you delete this post
