Joying 5.1 HU, USB connections

Re Post from MTCB forum,
Just installed a Joying:
. SKU: JY-UL124 . Quad Core Android 5.1.1 Lollipop OS Capacitive 7" High Definition for Universal Double Din . CPU: RK3188 1.6GHz Cortex A9 Quad Core, Resolution 1024*600. RAM：DDR3 1G, 16 GB memory
To my 2014 Australian Hyundai Elantra.
I waited to get the latest HU from Joying that has an unrated mother board and USB/ Comms board. With Lollipop 5.1.1. the unit performs very well with none of the problem previously mentioned on these pages. The internal and external mics are clear and the Bluetooth systems are perfect. Unit has been rooted and I don't seem to need for apps so I won't changed the software now.
The dimming for the button and the screen to follow the vehicles rheostat was fixed by making a circuit to invert and amplify the rheostat output to the HU ill line. Work's well, Kudos to the guys at the Subaru forums.
I had one bug fixed by Joying when the GPS nav was muted whenever I plugged in the DVR front camera. Joying quickly sent me a link to re flash my firmware and the problem was fixed. I have them currently looking into a bug when I view the DVR input shown on the HU I get lots of flashing to the screen in all pixel settings. I have been told this will be fixed in the next firmware update soon.
One problem that I can't solve is when I try to use my vehicles Multimedia Jack located in my center console. There is a Aux and USB jack there. All wiring from console to HU is complete. If I connect a USB stick to the Jack in the console then then HU struggles to connect and gives up. If I interrupt the USB plug and socket behind the HU then I am able to use the USB correctly. Looking at the car wiring diagrams there is a amplifier cct behind the Multimedia Jack supposedly to amp up the USB to HU. Doesn't seem to work?
Any ideas appreciated.

i have nothing to add, other than interested to see what the result is. Are you saying that your car comes with a built in hub in the console, and you are trying to make that USB port in the console work to the Joying head unit? my vehicle is similar, and I would like that to work as well
Update
Yes I have a console hub I guess.
The book calls it a multimedia center. Just an Aux port and a USB port or Jack in the tidy bin in the center console. If I by pass the Jacks and directly put the USB stick into the USB tail from the radio then it works fine. When I plug into the console port it tries to read it and fails. The HU then reports a read fail, have tried other known working USB sticks.
I have inspected behind the console jacks and found a cct board attached to the Jacks and then to the car wiring. From looking at the diagrams of the car previous to mine I see a cct board containing what looks like an amplifier. Tracing the car wiring to the radio input connectors seems to be OK and the wiring correct. Voltages at the radio connector are right in that there is 5v +ve, negative - earth and the center pins are data as they should be.
The console Jacks

The wiring for same (mine is same but more complex)
w.hemanual.org/multimedia_jack_schematic_diagrams-2036.html
Really bugs me not to be able to access that USB input Jack esp as the radio is a great unit.

You need to post this question in the MTCD (Lollipop) hardware thread. This thread is for MTCB (KitKat) units. The hardware in the MTCD headunits are very different than the MTCB headunits.
Thanks and done - I still have the same problem

Hello, i'm interest in tthis unit,https://www.carjoying.com/quad-core-android-car-radio/quad-core-vw-android-car-radio/joying-2016-latest-aftermarket-european-warehouse-lollipop-android-5-1-1-car-head-unit-autoradio-quad-core-double-din-gps-navigation-system-stereo-radio-support-reverse-camera-dvr-g.html and dont' know if it's the same you have. Can you tell me if you have some lag problems or something? does the hardware handles well the software?

Bob
Seems the same. Same CPU, platform, Specs etc. I think being a "VW Golf Passat Jetta" model from Joying it probably has some firmware in it to pick up your particular car's Bluetooth connections. The front surround looks like it has been added to my "Universal" type to fit neatly into your dashboard. The case and rear connections are identical. I see they have added a CanBus box which my car did not need but looks like yours does. There is probably a harness with it to fit your wiring loom.
if you run a lot of apps at once there is some lag not bad though. Like if you had the radio on and the GPS on and DVR the traffic then that's a pretty big load so then there is some lag but you get used to it. You might have to wait a second before an icon or screen switch becomes available. When running only a few apps at once there is no lag issues.
I like mine a lot, would not replace it with the OEM.
The problem mentioned below is one with my car only. My car's remote console jacks for the AUX and USB have their own preamp so I have by passed them and put in a aftermarket remote Aux USB and that works ok.
I am half way through doing a write up on the modifications and install if anyone is interested.

Hey mate, does it run Android auto? Trying to figure out which units can and can't. Looks like any running Android 5 can but trying to figure it out. Thanks!

Probleme on Renault Captur Android Head unit

Good morning all. Here's my problem: I own a Renault Captur vehicle. I wanted to install an Android car radio bought on Aliexpress. Following a first purchase and a bad cable sent, I could not connect my car radio. The car can contain two kinds of car radio. The seller then sent me another cable that corresponded to the three plugs to plug into the car. The original car radio is R – link. But after connecting these three plugs, the new car radio does not start. The Canbus is well connected. So I can't see where the problem may come from. This does not appear to be a hardware problem. But I'm probably missing a step. Unfortunately there is no manual with the car radio and obviously the seller cannot advise me properly.
Can you help me ? I thank you in advance.

[SOLVED] How to get Erisin ES8113M Megane 2 CC RN-SS-01 canbus controller working

Hi there. I searched (at least I tried for several hours without luck) this forum and the internet in general.
I have bought a ES8113M from Erisin (https://erisin.de/products/-655) with Android 10 preinstalled and a RN-SS-01 canbus decoder. The issue is that the steering wheel controller is not working. Does anyone have managed to connect the canbus of their Megane to the Android head unit?
Please tell me if you need more info. I am happy for every litte hint on PIN Layouts, factory setting, firmware upgrades or anything else.
Thanks in advance

What did seller suggest when contacted for support?
Is this an FYT based unit?

Thanks @marchnz for your quick reply and thereby help .
Support is poor. I asked two times over two different channels but did not get any answer yet.
Sorry to ask, I am new to Android head units. What do you mean FYT unit? Do you mean the MicroControlerUnit (MCU)-type? Then it's a S32F0 or LEIMA?
It says S32F0_LEIMA-W 20201020-17:05 HD1_7708_D_FF_C8
Oh I see you may ask because I posted to FYT Android head units. If this was wrong sorry and maybe a moderator will provide help and move to the appropriate sub forum (thanks).

@Badger50 thanks for moving this thread to the right forum. I hope someone still reads older (like in days ;-) threads and is able to help and or ask questions for me to better understand and hopefully solve my issue....

Is there a possibility to connect the shown connector directly to the radio?
Did you get the right cable tree from the seller? Normally the CAN adapter is connected in between the car-cable tree and the radio.
Is this the right CAN adapter for this radio, provided by the radio seller?

Thank you @rigattoni for your reply. And yes, the Canbus-Decoder ist connected to the Megane on the one side (for power and canbus signal) and the radio (see pinout picture from erisin). I would confirm this as you say it's "normally". I think and hope I have the right harness. At least the QR code says for MEGANE 2 and the website / the seller state it is especially designed and adapted for the Megane 2 (https://erisin.de/products/erisin-e...wifi-4g-dvd-obd-canbus-swc-für-renault-megane).

I did some more digging and analising today. Here are the colors of the ISO-Adapter with the according functions as far as I could find out on the internet (First screenshot). I also compared the cables from the harness and the radio to the canbus adapter (second screenshot). And finally I checked the connections to the radio and the link from there to the canbus adapter again (third screenshot).
It would be nice if someone could confirm some functions and if especially the canbus connections from the harness are the same with your knowledge (at best from another Renault Megane CC2 driver ).
Also I am curious if someone can shre more intel on the canbus cables of a Megane convertible 2.

What if the wiring is fine. I measured 5V between RN-SS-01 PIN3 / PIN4 and GND. To me that makes sense for a canbus information channel... Lots of messages on high...
Can someone provide the correct parameters for the Android head unit? I did a factory reset, an android reset and a SD0 card wipe. Unfortunately the car settings and factory settings remain as I did set them during testing.
For the canbus type (in the factory settings) I think it was 0x00 OFF when I first installed it. I cannot select it from the "select your model" screen (see above, RN-SS-01 missing). But I can set it to 0x85 RENAULT MEGANE SP...
Any intel on what canbus type should work? And how can I test it? In the car settings there is a menu entry steering wheel settings... I did reset it during testing and now even if I press a button on the steering wheel control, nothing happens. I would assume it should pop up a message on which button recognized and ask for what to map it to...
Sorry I am a bloody n00b here....

Sorry for starting this thread, but I would like to finish it with an easy statement: My car hasn't CANBUS (because manufactured >>before 2005<<). So I needed to go with an analogue adapter.
After a very friendly and productive phone call with a German vendor I bought this one here:
https://www.niq.de/lenkradfernbedie...---Scenic---Trafic-Bj--Ab-2000-fuer-auna.html.
From there on very easy to install. Connect the ISO cables from the car to the ISO adapter from NIQ and the departing cables to the ISO connector from the ERISIN head unit. Additionally and to get the steering wheel control working I had to connect SWC1, SWC2 and GND from the NIQ-adapter to the head unit.
Thanks for everyone reading and helping. CASE_SOLVED

Hello, I ordered multimedia for megane 2 ( https://www.aliexpress.com/item/100...020888279!sea!BG!0&curPageLogUid=eazK1RuTtlpe) but the can-bus decoder doesn't work, I ordered another one from another dealer but the coupler is smaller, is it possible to connect the wires to the new one. The new one is labeled "Megane 2" and I got it with cables but they don't fit...

Carplay not working with cable USB

Hi,
I have two head units, one EKIY T8 Android 10 that uses Carlink for connecting to Carplay on my iPhone, and the other is a T10 Srnubi UIS7862 that uses Tlink 5 to connect to iPhone Carplay.
On the T8-Carlink I connect the iPhone through USB and Carplay works, and I can swithch between my wife's and mine by connecting them through the cable.
On the T10-Tlink I can't connect iPhone through USB cable. Sometimes it doesn't do anything, others it says it's connecting but never really ends. The only way to connect is through Bluetooth pairing, but I find it more difficult to switch between phones, and in my last trip I experienced problems; when I passes close to an official building with frequency inhibitors connection got lost.
Should this connection through USB work for my phone or is this unit only capable of wireless?. What could be wrong?
My iPhone has iOS 16.1.1 and the Tlink software is 5.2.60.
Info about my head unit in picture attached

I received my T10 head unit today, it is TS10 uis7862
I am using tlink v5.3.21, my head unit came with 2 usb cables (one 4 pin one 6 pin)
I have tried both cables with 2 genuine apple cables and can’t get it to connect via usb.
The radio prompts me to press trust on the phone, but I never get the prompt on my phone. iPhone 14 pro max iOS 16.2
Anyone get this issue before? Wireles CarPlay works but is very buggy. If I leave CarPlay to go to radio I have to force quit app and manually reconnect phone again to get CarPlay back
Thanks

This is the wrong forum section for your unit.
This section is specifically for FYT devices.
Your device is a TS10 which I think should be discussed in this thread here
The devices are quite different firmware wise and the correct answer for an FYT may not be correct for a TS10.

Hello everyone, i'm new here and know nothing about this stuff but im learning slowly . I bought at local dealer this radio Isudar T72 10'' screen, 4GB/32GB and place it in a VW Golf 7. everything is working fine and im happy with it but every then and there after the ignition of a car audio starts but screen is DEAD.
If i press buttons on a radio after half a minute screen gets activated. Next time radio works fine and so on......
I have also replaced the radio with a new one and today this error happend again. I been told that could be some error with CAN BUS of a car and the radio?!
Does anyone have any idea what could be a problem??
Thanks and bye

Thanks for the reply.
Just because i was affraid of this problems i took a car to this dealer who installed everything. Also as he said he never had problems and been already installing into this kind of cars. Now he sent me second radio but without canbus module. The error is the same.
My original radio didnt have separated MOB and it was all installed directly into the screen. Sleep mode doesnt affect much and its just too long to be activated every day.
Maybe we need to think also about replacing this canbus module.
I will check your links.
