New android head unit

Hi guys!
Finally it looks like I'm going to replace my car, and I'm going to take my a amplifier and components to a new car, but not the head unit. I'm seeking to buy a new android head unit, and found this one on eBay:
https://www.ebay.co.uk/itm/25369100...7d776fc1640a9cbe7502037fff88436&ul_noapp=true
The main issue is that unit should fit Volkswagen Jetta and should have pre out, so it will be connected to external amplifier.
What do you think about unit I mentioned above? Any other suggestions?
Thank you

I have one of the smartech ones from ali express which I am impressed with

Thanx for advice!
I see that all these units can be connected with standard connector (i think it calls ISO connector), and also there are RCA outputs. Are these RCA outputs come before the internal amplifier and can be connected to external amplifier?
Thank you

All units can use an external amplifier. all of them have RCA for this.
All the specialised units like volkswagen, mercedes come with Quad lock and not standard ISO tho.

so if i have VW, i must look for the HU compatible specifically with VW?

Hi guys!
I'm waking up my thread. Almost month ago i got this unit https://www.ebay.co.uk/itm/10-2-4G-...e=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649, it should be (according to description) be compatible with my VW Jetta 2015. But once it was installed and connected it behaves little bit strange: all car info (such as doors status for example) and steering wheel control works till the engine starts. When engine was started all these things stopped shown and work. I checked that power cable is not connected, and the seller sent me a new CANBUS, but it still doesn't work. I will appreciate any help on this issue
Thank you

Solved - just used the canbus decoder from previous installed system

Uknown option in my radio

hi there
i have a few options on my radio...but i donw know what they mean
first:
GPS MIX
what can this be?
https://imgur.com/a/NYoeGZt

Antenna normally ON
https://imgur.com/a/RsQS4on
3
activation ..when clicked says
no application
https://imgur.com/a/zX95ylB
4 -
A/C Information On / OFF
if i turn on, the air conditionar image appears when i turn the radio on...but how to send AC signal saying the status to the radio?
anyone knows how to manage this option ? what are they for?
thanks

Don't use imgur.
No way I am going to register and logon (because that is what imgur requires), because someone wants advise.
(or did you "protect" your images?)
Edit: Sorry. Only first image.
1. You have the american GPS system and the Russian Glonass system. GPS mix means that both systems are used which increases accuracy a lot.
2. You have antennas that can extend/retract into the car's bodywork. That is what this is used for but I do not know what ON or OFF means (I do not have such an antenna)
3. Don't know, but I guess it really means that the necessary apk is not in the firmware and therefore not on your unit.
4. ?? What do you mean?

No it doesn't, but on reply the link is displayed.
The CAN bus sends the statuses of the airco to the unit. If you change "something" in the airco settings it will be shortly displayed in an overlay by the CANbus.apk.
In some cars with some CANbus controllers it is even a 2-way functionality: You can change airco settings from the unit.
The door ON/OFF is also controlled via the CANbus. If you open a door it will be shortly displayed in an overlay by the CANbus.apk.

yes the door is working but not AC info...
maybe because i have KEY1 and KEY2 wire not connected ?(i dont know where to connect it)~
@surfer, i have found a few solutions for my head unit, do you think a good idea to start a FAQ thread only with answers for common questions?
i can help but i am not experienced making the thread...if you help, then i can try to feed the thread

key1 and key2 have nothing to do with the door. For the AC you have to ask Joying.
I already created such a Q&A thread, but it already moved to page 5

A/c is for the VW CanBus. If you install the Unit with canbus into a VW. You can control the Hvac system along with a few other features. Also your cars info will display on your radio. Without owning a VW. You would need to add a BT Obd tool. Like $5-$10 on ebay.

Thanks for the reply
regarding Key1 and Key2 can you help?
thanks

In the Joyings you have CANbus models that come standard with a CANbus for the type of car you have. These units also have a CANbus motherboard. These units ONLY read the CANbus whether you have steering wheel keys or not. The key1/key2 cables run via the CANbus and only "understand" the binary CAN pulses because there is a different circuit on the motherboard.
These motherboards can not read resistance over key1/key2.
Other Joyings come with a universal motherboard. These units do not have a CANbus and therefore not a CANbus motherboard. These motherboards only read resistance over key1/key2 because of the other circuit on the motherboard.
Of course it is the cheapest to just produce one motherboard with 2 circuits on it. This means you can modify your universal motherboard to CANbus motherboard, or the other way round, by soldering/replacing some resistors on your motherboard. That is the only direct way.
You have a Joying compatible and you mentioned you have a CANbus. I guess it works 100% the same as on a Joying, so that means that your key1/key2, via the CANbus, can only read CANbus binary pulses.
You will not be able to use resistance based SWCs with your unit without soldering OR you should use the [Joying for VW] Universal steering wheel controls with arduino from @bambapin.

well i have a canbus adapter.
my car is a renault Clio IV
the problem is that the keys are working, but i cannot program them in other way, also if i make canbus info print it is receiving data, but apparently not preocessing it.
maybe i can share photos to explain better the problem?

Did you change settings in " Factory Settings" ?

Did you find any solution?

Hi! I have the same problem with TPMS device USB connectivity with Android multimedia head unit. I tried everything, but so far no result.
Did you find any solution?

Hi! I have exact the same product and i see exact the same pictures, that means I have the same issue on my head unit PX6 with Android 11. I also updated the app to the newer version without any result. Any idea someone?

Hi, I didn't solve the issue. I have tried TPMS on two other car Android multimedia with Android 6 and 7 versions, but without any success.

Do you guys own the TPMS from the head unit seller?
If not there is most probably the issue.
There are wo many aftermarket TPMS... and the head unit supplier just implements their own stuff. Also OEM TPMS are mostly not supported.

TPMS is not from the head unit seller. Supposedly it should work with Android car aftermarket multimedia, but it seems that's not the case.

Exactly!

If I have a look at the provided pictures... It seems to be clear: The TPMS on the wheels are not connected. They need to get activated wheel by wheel.
So go through the settings of this app and try to get them activated. Ask the reseller how to activate if that is not written anywhere. If this is not possible: Send them back and get your money back.

Sorry, byt this is not correct. I 've tried everything, but the problem is not the avtivation of the sensors. The usb receiver can not be recognized by the HU. The app runs, you can choose the wheel sensor to connect, but nothing happens. The power light on the receiver flashes as before, and nothing more. Thanks anyway!

Junsun v1 pro no video plays and no Sound

I have a junsun v1 pro 2GB/32GB and a problem.
I need technical support please.
all videos or YouTube etc. do not work. there is simply no sound and after about half a second every video stops. I can't watch a single one. only the radio makes a sound.
what do I have to set so that I have a sound everywhere with every application? The radio gets the internet from my mobile phone, which is connected via a hotspot. Reception is very good.
I ask for help

Video is forbidden in nearly each single country while driving.
This is no issue, this is expected behavior.
You need to connect the handbrake cable at the cable tree of the radio and if you want to watch videos, you are able to do that when the handbrake is active.
You can workaround that with connecting this brake cable to ground, but as I said... It´s not allowed.

Thanks for the answer.
just for understanding.
With the wiring harness that was supplied, can I connect the cable with the brake to the ground of the same wiring harness? Does that mean then also ground the cable or connect it to what exactly?
that would be great if it worked again. Of course only when I'm not driving

Is this right? Must i connect ACC and BREAK on the same tree to watch videos while driving?
expand...BREAK needs a positive(!) signal so it makes no sense to connect it to GROUND of your car.
If your car doesn't provide a BREAK wire or you want your kids watching videos while driving, you can split ACC and connect ACC (from car) additionally to BREAK of your head unit. Your head unit will get power on BREAK as soon as you turn on ignition.

I don´t know your unit, but all units I have, have a switch somewhere in the settings to activate Video while driving.
You really need to figure that out.
Normally the break-switch in most of the cars is ground switched to light up the warn signal in the instrument cluster and not power switched.
But... If you trust the information you just provided... go for it.

You're right, when I'm stationary and put the handbrake on, the video doesn't stop.
I tried to connect Brake to ACC but I can't find the right cable.
do you have a tip for me?
I also found the setting to interrupt the handbrake. I deactivated this. do I still have to connect the two cables or not?
Or should just changing the setting be enough?
Thank you for the help

Last questions.
how can i find out which model i have? i have a junsun v1 pro. but which one? it doesn't say MTK8259/8257 anywhere?
and how do I get into the secret menu with the special settings that everyone always shows with the whole bar of radio settings and can settings, etc.? I don't see a gear when I go to device in auto settings.
and of course I will report in detail.

Hi.
I switched it in the handbrake break menu (open, closed, speed). when open and at speed, the message while driving appears immediately and so on. when closed, there is no message but again every video stops immediately after one second. so this doesn't help.
What else can I try?
I wanted to do an update but after 50 attempts he showed me for about 10 seconds that he was doing an update something with Ts and then end. were only two lines that were there. then it started again normally with the same version. so it doesn't work either.
I have the feeling that my system is somehow not open to all settings. what else can I do?
I'm going crazy with that part. nothing works.

Perhaps i can go to the Secret menue but i cant find it. Can i try a another Software for this Radio?

I must correct myself. I'm sorry.
actually when standing and with the handbrake on there is a sound and the video runs normally.
how can I still bridge the fact that I can watch videos while driving?

Android radio and problem with central lock after install -Citroen ds5

Hello Everyone. Sorry for my bad english not my native language.
I read all internet and cant find solution to fix my problem.
I buy this Heade Unit - https://pl.aliexpress.com/item/4000...t_main.21.21ef1c24K3NInA&gatewayAdapt=glo2pol
Afrter install everything working fine (steering wheel buttons, 4g, GPS, etc) only one problem with cetral lock. When I turn off the ignition after about 5 minutes, the central locking does not work with the remote control, and when I turn it back on works normally. Funny thing is that 2 people bought this radio but with android 10 (i have 11) and they all work.
I check canbus setting in the herad unit option and i have RZC >Peugeot/Citroen>ALL. The name of canbus is Raise but i dont have on the list that name. I can change RZC to ALLWORLD>Peugeot/Citroen?DS5 but what I wouldn't choose the door functions,sensors etc - not working. Only RZC >Peugeot/Citroen>ALL. have correct setting, but what about cetral lock? how to fix that -it looks like the radio puts the key module to sleep. in the settings I have something like lock control but some pin wants:

You really should contact the seller.
As you did not show MCU and Android version, no one would be able to help here.
On top: The French cars are some sort of difficult and b i t c h y, when it comes to CAN connection and providing car functionality. May be you got the wrong CAN adapter.

Spoiler: photo about device
Seller send me canbus Raise like one the pictures
Spoiler: CanBus
tell me what to do?
And last thing he send me RAISE can bus and when i check in the settings i don't have that Can BOX TYPE, and must use like on pictures - because it's the only one that works (steering wheel buttons) but no central lock
Spoiler: CAN BUX TYPE
but i can update this:
Spoiler: UPDATE CAN BOX
can a bad canbox setting cause this problem?

serenity15 said:

Click to expand...
Click to collapse
Yes sure. Even if you chose the wrong type (low, mid, high)
Remarks:
That the door lock is not working anymore with connected radio, that tells me that there is a mismatching CAN box setting. Seems to deactivate the central locking mechanism, there is an interference in the CAN signals.
That should throw an error message in the OBD for sure. You need to get in contact with the seller again and tell him that there is an error which deactivates the central lock.
Ask the seller which CAN box settings to use. If the sell units for your car, they should know which version to use to get at least most things working as expected... But you should know: There is only a minimal set of functionality available for most cars. Mostly they are providing Clamp 30, Clamp 15, RVC and light.
If your car is not listed in the CAN settings, you should not count on any further functionality.
You can update the CAN box, if you have the right file for it. Did the seller send one to you?

I checked all settings. I can mark my car on the list but if i do this steering wheel buttons not working (only on that HIGH). I Update canbox but its nothing change (no new funcion, settings etc) work like basic.
maybe some settings of the radio cause the BSI to go to sleep. some function consumes energy and bsi sleeps to save energy.

Just to drop here some info that may be useful to someone. I had precisely the same issue with the central locking system on a Citroen C4 II e-HDI, basically same stuff as DS4. The problem was the canbus decoder (Raise). I was sent another one from simple soft (XP type) and it works perfectly. maybe it's helpful for someone else. regards

Sorry to resume an old post but I've finally managed to solve this issue without external players.
Basically, what happens is that the ****ty Canbus BOX "raise" it's like always connected and draining energy.
You can lost a lot of time talking to the chinese seller, OR (if you have a bit of DIY skills) you can simply connect the RED wire of the canbus box to any power source that goes on when ignition is on (for example any led or the lighter 12v).
After that you'll enjoy a car without any chinese headunit added issue!! Cost of this? 0 euros!
