Hi, I have a MTCE unit.
2 days ago it has stopped working. There is no power. This may have been due to me making a bad connection with some cables...
I am trying to work out if it is recoverable e.g. is a replacement board an option rather than buying a new head unit... Or whether it could be fixed!
There are some non-android related buttons on the unit's shroud that have stopped working ie. hazard lights and central locking. So I'm wondering whether a board replacement would help or whether the issue is elsewhere to do with power.
Car fuses seem fine and all other dash functions (not related to head unit) are fine. I'm not sure
I have a multimeter and some coffee... Is anyone able to provide some diagnostic help/steps that can help me decide whether to try a new board or recover the head unit?
Thanks!

Hi!
I'm new here and am wondering if someone could help me out.
I got an Android headunit through a local workshop. I thought it'd be an upgrade, and in some respects it is, but it's been giving me endless problems. I've also eventually come to the realisation that the mechanic is pretty clueless about troubleshooting software issues (I suppose he's more of an installer) so I'm pretty much on my own here. He's talking to his supplier but has been established these Chinese suppliers aren't usually helpful.
There are 2 things which I can't figure out:
1. On day 1, the bluetooth worked. I could pair my iPhone with the headunit through the unit's stock "bluetooth/dialer" app. But the unit wouldn't power back on after it was installed the first time. Mechanic told me the the unit came shipped with a wire switched around and once he corrected that problem, the headunit has been working pretty reliably. Bluetooth stopped working after this, however. I've done a factory reset, tried the RST button upfront but to no avail.
I've go to settings and searched for "bluetooth" (yes, noted that it's hidden on these units!) and made sure it's switched on. Occasionally, I see my phone's name appear on the "settings" page, but I can't pair it with the unit. It remains stuck on "pairing." It still searches endlessly in the bluetooth/dialer app.
Is there anything else I should look into?
2. Can the OS and firmware be upgraded on my unit? I unfortunately, have no idea what brand/model the headunit is. My car's pretty rare in my country (Renault Clio 2015) and the headunits on Aliexpress were for a lower-end version with different connectors. The workshop got a unit for my model through its Chinese contacts, but it came in a non-descript box. Here's the info I've gotten from the Settings screen:
Processor type: QuadCore-T3
Android Version: 7.1.1
MCU version: T5.3.21-63-9B1-C06101-180904
System version: V8.3.2_20180919.193359_ZH5-N
I'll be going through the forum to learn as much about Android headunits but would appreciate any help in the mean time.
Thanks!
Spent some time looking around the forums. Thought I'd log what I've discovered for others who may be searching for similar info.
To recap, I have an Android head unit with no branding. Initially, all I had was the info from the "about device" screen, which provided a bunch of numbers.
I got more information by downloading a hardware info app. There are a few but they generally work the same by providing you with more hardware info (ie. clues).
Discovered I have an Allwinner T3 P3 system. I'm sure I'm lumping several things together but it was enough info to search the forum with.
Discovered this wonderful thread which is generally about Android units based on the above chipset.
Within that thread I came across this one which was extremely helpful. It details how there are 3 types of Allwinner T3 P3 systems which are all different as far as firmware is concerned. Links to their respective firmware are provided, as well as some info on how to reset/recover the system. Glad I found this as I have a better idea how these things work, and more importantly, it cautions against what NOT to do (and risk bricking your headunit).
The the post also links a Russian site that has even more info on my unit from the Allwinner T3 P3 family. Will explore this next (thanks Google translate!).
Will also try to do a factory recover to see if I can fix the bluetooth problem. It worked on Day 1 so at the very least I know the hardware works. That said, who knows if the hardware was fried when the wires were switched around.
Solved the bluetooth problem. Answer was in the Russian thread posted above!
Thank you, just got a unit with same MCU version and your post has helped me identify this thing!
Hi Ultimax,
I have a small question. I have the same car as you ( a 2015 clio 4) and I'm wondering about the Canbus configuration to use to get the steering wheel boutons to work? Looked everywhere and nothing on this topic so I'm really waiting for your directions..

Hey!
Glad to help!
What headunit comes installed in your Clio 4? Is it a R-Link TomTom unit (without the USB port next to the screen) or the more basic MediaNav (with the USB port next to the screen)?
If it's the MediaNav headunit, you're in luck. There are quite a few aftermarket Android headunits which are supposedly plug and play, including steering wheel buttons. At least that's what's claimed. I know Pioneer Europe has a headunit which is a 1 for 1 replacement for the stock unit. It even comes with a new plastic front so it fits perfectly and a new wiring harness.
https://www.pioneer-car.eu/eur/products/sph-evo62dab-clio
If it's the R-Link TomTom unit, then I'm afraid you're out of luck. This is the version of Clio 4 I have unfortunately. I've searched high and low on the internet for a suitable wiring harness+CANBUS which would allow me to use the factory steering wheel buttons but couldn't find any. The closest I came was one I got from China through a local installer, but only the volume and channel up/down buttons worked. The Android headunit itself which came with the CANBUS was sh!t and I was tempted to go back to the factory unit. Only thing keeping me from doing so was I'd already spent too much time and money getting it to work somewhat.
However, I recently installed a new Pioneer headunit. My local installer managed to replace the Android unit with it. He couldn't get the steering buttons to work though. He said he'd have to custom program one which would be pretty costly. So, I've given up on using the factory steering wheel buttons.
A cheap workaround is to use an aftermarket steering wheel control kit. You attach new controls to your steering wheel (either clipped, glued or recessed into new holes drilled into your steering wheel). The controls are powered by a long-life battery. The control unit is paired wirelessly with a receiver which you connect to the your headunit via the KEY1/KEY2 (Pioneer calls them Input 1 and 2), ground and ACC wires. Most headunits have these wires.
This is the option I'm going for. My kit hasn't arrived yet but I'm optimistic it'll work.
FYI, this is the one I bought:
https://www.aliexpress.com/item/4000584816400.html?spm=a2g0s.9042311.0.0.317a4c4dfTx6k3
There are other designs too. Just search the site for "universal steering wheel control radio"
Hope this helps!
So i installed my head unit yesterday in my 2011 BMW 118D MSport i have cut out the original cup holders in order to get the iDrive to fit however it does not work it is 100% connected correctly as the idrive controller is lit up even when the car is locked with engine off which im guessing is a bad thing i have looked all through the settings trying to find if there is a toggle to turn the controller on however i do not see one i have messaged the seller and still no reply i was wondering if anyone on this forum has had this issue and knows how to fix it? im guessing if i had a better flash on the unit its self it may work here is the unit i have bought and the make of the unit is SYU-Android if that makes any difference
Base on what you describe, it's indicating a permanent 12V (from battery) is connected to the "ACC" pin of the Android unit. I would double check the wiring harness with reference to a known good pin assignment diagram for your car model.

Hello,
I am using an android head unit (px30) in a ford Mondeo mk4. Suddenly the screen did not power on and found that the canbus stopped working. I need to buy a replacement one, but I need to ensure that will work in the specific model. I 've tried to ask sellers in aliexpress (dasaita, isudar, etc) but they can't confirm that will work. Should I take the risk and buy one? Is there a way to check and pick the correct one? (Mondeo does not have ACC connection pin to power on red wire coming from iso cable through the harness, it needs canbus and CANL+CANH will tell the unit when to power or not, so i had to modify and connect both red-ACC with yellow-Power cables together but now I have to shut down the unit on my own). So Is there a way to find the correct canbus for ford or does not matter which one to buy and confirm only the car model?
Thanks and Regards,
Tasos
I take it you didn't buy your HU from Aliexpress or you could just ask your original seller to sell you a new one. In theory any Mondeo MK4 CANbus box should work if all you need is to control power and illumination as those are separate wires coming out of the CANbus box. You might get compatibility issues if the new box doesn't translate all the bus messages your HU needs for other features like temperature, open doors...
I would suggest you start by opening the broken box and re-solder all the connector pins and any other pins of roughly the same size you see.
Hi, New to the site and a greyhead who knows nothing about the electronics of these things. I installed a Navitree Y1E Android 11 4core 2+32GB Car DVD player for Ford Focus 2 2004-2011 audio for car video AM FM RDS 4G WIFI BT in my 201 Ford Focus. All appeared well as fitting was easy. All looked great and now I have found there is a constant live feed to the unit that is the possibe cause of a flat battery. My son is a mechanic and accepts he is not electronically knowledgeable, but he tested the wires and found a Yellow wire that was live and for memory, but there was a red wire that was permantly live and should be a switch feed. Can anyone advise if they have had experience with this model (Direct from China) and what is happening? Appreciate any help.

Hi Guys asnyone able to help. No help from supplier and looks like I will have to ditch the headunit..
Why would you ditch the head unit? It needs the permanent power on the yellow wire and a switched feed on the red wire. Your vehicle is currently not providing this so either you have wired the unit to the wrong feed or there currently isn't one so you'd need to find a connection in the vehicle which does switch with the key and run it to the red wire. As the red wire is only a sensing input it doesn't need heavy wiring.
It is not a head unit fault.
Note some vehicles supply the switching information to the stock head unit via the CANbus, yours may be like that and would explain the lack of a switched feed at present but you can easily overcome this.

Mr.TT_NZThanks for replying..appreciate comments..The red wire is going into the canbus via a 20 pin connector if it is cut the problem seems solved, so are you saying that I should have a switch cable run to that? See image for wiring.
Ah so you do have a CANbus module, I believe there are some issues with switching via those modules but I've never had one to play with.
You could try removing the red wire from the CANbus module and connecting a switched feed to it instead (not as well as) so the head unit only gets its switch control from your new wire. Maybe that CANbus module is not exactly correct for your model of car, there are so many variations even within a certain model that it is hard to see how the people who write the software for the modules can keep up with all of them.

Thanks again. I will try this...did a bit off research on the canbus and there is no UK retailer who will sell me a Ford canbus and guarantee it will work! Most said it would be a sale with no return.. Hey Ho..
Hi all,
I bought my first car 2 weeks ago, a Renault Clio 2014.
The first upgrade i wanted to do was a android head unit that supports android auto and apple car play. after some research i ended up with this one:
https://nl.aliexpress.com/item/1005003495893052.html?spm=a2g0o.order_list.0.0.291279d2UtKJ3v&gatewayAdapt=glo2nld
Model: PX9s 64GB 4G
€268,92
I got the radio in and it worked perfect, however i couldn't get the steering wheel volume controls to work.
After connecting the simplesoft box and pressing update on the head unit, the unit turned off and it remained this way... rip.
I think the unit is bricked. Im looking for somone who has the flash files or someone that has made a backup so i can try to restore the head unit
Keep in mind, im new to all of this.
I have found Junsun tech support to be very helpful.
Sorry I can't help any more than that.
Send it back warranty

I just got a t&t for a new unit, however as far as i know i can keep this one, is it possible to backup the new one and flash the old one with it?
Hi,
I'm new here too. I installed a Junsun V1pro HU on a Mégane 3. The canbus decoder is also a simple soft. Steering wheel control didn't work at first. Actually something was wrong in the harness and I had to swap the position of the 2 white wire of the smallest connector linking the canbus decoder to the unit.
I hope this can help.

I actually am getting my new unit in today, Is there someone who can explain how to make a dump so I can try the backup on my other unit?
Is it posible to put a Other car launcher on a Junsun Android radio i have a model 8227L
hi, I have a junsun with fw ts18 2.2, loading another fw I didn't realize it was for vertical system now I can't load the right one, how do I do it.?
Hello, help. The question of such a junsun v1 car radio. The reversing camera failed. Only the black screen is on. The connection was correct. What could be the reason?When you click on the screen, brightness settings appear and nothing else. I connected another camera the same
