Steering wheel control problem between Autoradio 8227L and Toyota Yaris II series

Hi everyone, I hope to be writing in the appropriate section.
I bought an 8227L android car radio:

- http://imageupper.com/s12/1/6/M1568803747176376_6.jpg
And I have a Toyota Yaris II series:
- http://imageupper.com/s12/1/6/M1568803747176376_7.jpg
This morning I successfully mounted the 8227L stereo in my car
- http://imageupper.com/s12/1/6/M1568803747176376_5.jpg
and everything works fine except the steering wheel controls.
The old original car radio (where steering wheel controls worked) was so connected:
- http://imageupper.com/s12/1/6/M1568803747176376_4.jpg
And when mounting the new autoradio 8227L, I just inserted the cables in the appropriate adapters.
The fact is that as soon as I enter the steering wheel configuration menu, I press START and select a command to associate with a physical steering wheel button, I get an error:
- http://imageupper.com/s12/1/6/M1568803747176376_3.jpg
even trying to reboot:

- http://imageupper.com/s12/1/6/M1568803747176376_1.jpg
I still get the same error.
Can u help me in some way? Thank u all in advance!

As a first step, I would put a voltmeter onto the sense wires while pressing each of steering wheel buttons- to confirm that different voltages are available for the head unit to learn
This wil prove or otherwise that the wiring is in order.

Hi Pxdev,
First of all thank you very much for your attention.
At the moment I do not have the possibility to use a voltmeter, however I am sure that the steering wheel controls work (tested up to a few hours before the installation of the new radio) and also the installation of the new radio has simply consisted in disconnecting the 3 connectors ( http://imageupper.com/s12/1/6/M1568803747176376_4.jpg the blue and the two whites) visible in the picture and insert them in the appropriate adapters of the new car radio and insert a single connector in the special housing and everything worked, except, of course, for the steering wheel controls. Is there anything else I could try to do? Many thanks in advance.

Hi,
Have you bought it with the Canbus and cables for your car? I have the exact same unit and the steering wheel works well.

I get the same error , found a video saying ground one wire to radio ground and any one key wire ground radio but doesn't work. If anybody has any solution or troubleshoot guide please let me know .

Checked voltage , voltage from headunit around 3.5v , checked resisitance from each key shows different value for each key. Now what to do?

Did you find a solution to your problem as I'm having the same problem with mine. Same head unit with a Raise can bus installed. The steering wheel controls worked fine when I first bought the car but I decided to delete some of the unused apps and since then the steering wheel controls don't work. I can't even remember the name of the app I deleted. Any help would be grateful.

BT problem with Seicane Android HU for HONDA CR-V 2015

Hi,
I am using Seicane 9" PX30 HU Android 9 in my Honda CR-V for a few months.
I'm very satisfied. The only problem I have is that my honda phone buttons do not work on the steering wheel. All other buttons are working ok. Is it problem with CanBus interface ? Did someone solve this problem for CR-V ?

Hi,
Try this resolution:
1. Open cover of Steering wheel.
2. Locate the wire at pin 3 (as picture).
http s //drive_google_com/file/d/1OVIjfgHGjEe5yIgrwA1_YGj3MCY36pMU/view?usp=sharing
3. Connect this wire to the Key 1/SWC 1 or Key 2/SWC 2 of the HU.
4. Set SWC buton on HU
DONE !

Hi, did the above solve your problem? or any other solution?
I'm looking at this same HU for my 2014 CRV, are you still satisfied with it? Any pictures of it installed?
Thanks!

i haven't tried it yet. i am very happy with the device. the only problem i have is that I coudn't adjusting the clock via the buttons on the steering wheel. Problem is bug in Honda firmware where on clock setting up and down arrow is not working. I solved this by disconnecting and connecting the battery in 1h am :laugh:

I'm just here to report a solution for adjusting the clock. I subsequently solved the problem by purchasing a newer can-bus interface module through alliexpress. And now everything works as it should. The Honda watch syncs properly with the Android device

Yeeees, connected according to the instructions and it works. In my case, only the wire was yellow, but on the same pin no. 3

PX5 Steering Wheel controls

Hello,
I bought an Android unit on July and after some troubleshooting everything was working fine. Now I have a problem. I have a Renault Clio 4 Pre-Restyling and steering wheel controls are managed by CAN-BUS. The problem is that Volume controls and radio station change don't work if I don't turn on Head Lights. Other canbus functionalities seem to be working fine. For example when I open doors I can see them on my video. Could it be the CanBus decoder faulty or I have to check some wire connection? Thank you

Anyone can help me? Do you need any further information? Is it possible to know the pinout of CANBUS connector? Usually is 20 pin.

9" Android YT9216B steering wheel control problem

Hi All,
My brother just purchased an all-in-1 9" Android head unit + facia for his 2005 Mazda 6 (GG). Listing can be seen here:

He has installed the unit and everything works fine while the car's ignition is only turned to accessories. However, as soon as he turns the car key 1 click further to power up the ignition (but the not has not yet started), the steering wheel controls go nuts. That is, once the key is turned to ignition, it's like one of the steering control buttons is constantly being pressed and the head unit either continually skips through songs or it continually skips through tuning radio stations, depending on whether the unit is set to playback songs or to the radio. Curiously, this problem doesn't occur when only the accessories are powered on (ignition not yet powered on).
The details of his unit are shown in the attached image. He currently has the steering wheel controls disconnected due to the issue, which I'm guessing is why the unit shows "Ruishengwei-Mazda6--disconnect".
I did some searching but didn't find anyone else reporting this issue. Anybody have any insights as to what might be the issue? If so that would be greatly appreciated.

What did the reseller suggest when contacted for after sales support.

My brother has sent a message to the seller querying about the steering wheel control issue, but no response yet, unfortunately.

Okay, good news. My brother managed to sort the issue. For anybody who has the same problem, here are the details of the fix that worked for him:
Coming from the 9" Android headunit there's a wire called 'Key 1'. This Key 1 wire needed to be connected to the red/blk wire of the Mazda's headunit wiring harness.
I should also mention that his Mazda 6 GG has the non-Bose stereo, however, as seen in the attached image, the non-Bose and Bose headunits both have the same red/blk wire.

JUNSUN V1 PRO UIS 8581A (TS18) - SW key change with CANBUS decoder plugged in

Hello everyone, it's been a while in this forum .
I recently purchased a unit from Junsun with processor UIS 8581A (this was not provided in the add) and started to play with the unit on my SEAT Ibiza 2011 (09-2013)
I noticed that the steering wheel commands are connected through the CANBUS decoder unit from Simplesoft and I am unable to change the keys.
Furthermore I am stuck in a carousel of commands for "MODE" key on the steering wheel tat swaps through NAVI>MUSIC>VIDEO>AUXIN>BT>Ipod and i think something else ) and I only need NAVI and MUSIC.
Details regarding unit:
Platform information TS18
CPU UIS8581A (8CORTEX a55 @1.6GHZ), 4Gb Ram
GPU dual core Mali G-52 3EE
Sound processor AK7604
Radio module TDA7708
Bluetooth 5.0
CAN VERSION:V3.88.139BYPS
MCU VERSION:TS18.1.1
SYSTEM VERSION;TS18.2.2 (20220629)
ANDROID VERSION 11.0
I would like to ask for help for these Issues, questions:
1. Is there any way to change the "Mode" function on the steering wheel control (canbus decoder connected) to only carousel for specific apps.
2. Can I change the default music app to let's say Youtube music?
3. How to change control keys on steering wheel with CANBUS decoder connected? And if it's not possible is there a way without the CANBUS decoder connected, what are the downsides if this can occur?
4. I saw that there is a very big thread on another forum about these units but not here :-? why? (I live in europe and my unit came from Poland)
I searched the forum and tried SWC car switcher app, and some others but the buttons from steering wheel had the highest priority either way :-(
Thank you and sorry for the TLDR!

Some people disabled the standard SWC mode key by removing all apps from factory settings and use it for AppSwitcher:
Post in thread 'AppSwitcher - smart SWC launcher (for Junsun and similar devices) incl. autostart' https://forum.xda-developers.com/t/...-devices-incl-autostart.4435555/post-87531251
Another approach is to check if the SWC of Seat Ibiza is a resistance matrix and the connections are exposed to the wiring harness.
