[MTCH][11] CAN bus direct connection - Android Head-Units

Hi everyone,
I have Android 11 Head Unit (HU) from Seicane in my Ford Fusion 2012. The MCU version is MTCH_HF_V3.78_1 based on RK3566 chip:

I was provided CAN bus decoder FD-SS-02 from Simple Soft:
However, I have realized that HU has direct CAN pins on Power Supply Port (PSP) - pins 11 and 12 on attached sketch map:
But - they are on connected - just dangling out of connector. So my question is - Does anyone know what are they for? Maybe there is a way to communicate with a CAN bus directly from HU using some kind of app?
In addition I want to add, that this HU has no serial or other type of interface with CAN bus decoder. Only preselected signals from box to HU are available. The pinout from decoder is as follow (only 8 pins connected)
1) IN - GND
2) IN - MS CAN+ (from harness)(multimedia/middle speed Ford CAN)
3) OUT - ILLUMI (PSP pin 1) (not working - always +12V causing constant nigh mode)
4) OUT - break detection (PSP pin 14) (not working - always +12V causing that none function is blocked for safety while driving)
5-8) NC
9) IN - BAT+12V (always hot)
10) IN - MS CAN- (from harness)
11) OUT - ACC (PSP pin 6) (Accessory - turns on/off the radio based on ignition key position)
12) OUT - reverse detect (PSP pin 13) (normally +12V, when gear on reverse 0V and video from reverse camera starts streaming)
The illumination and break detection functions are not working. So my side question is that maybe someone know which model of this Chinese can boxes fits Ford Fusions 2012?
Thank you for taking part in discussion!

Peugeot 508 aftermarket radio no powering on

Hello!
I have a very strange problem with my android radio in my 508. When I'm trying to connect it with delivered canbus decoder, it's simply not powering on. I tried various combinations with power supply to the unit but without positive result yet. The only way that turns my radio on is bypassing power supply of canbus box and conecting it directly to power in on the unit. I thought that maybe canbus decoder is defective, so I returned it to supplier and received new one...still no success. I have red many manuals and forums but I cannot find the answer how to power on the unit with canbus decoder. I really need it to be connected because I need steering wheel buttons and readings from car computer (like AC, fuel consumption etc.). I know that to maintain it, power supply must be connected to canbus decoder, which triggers signal to power on the unit. Somehow it just doesn't work. I measured voltage on power harness, there is a good reading. I have also readings on canL and canH line. Everything is good on input side to canbus, on output I have zero...just like canbus is not working.
My radio is 1din android 8 unit equipped with canbus decoder:
decoder: MH (PA-SS-05)20180402
SS-PA0503271018-2
For: Peugeot 2008
P/N 1801300412
Software: PSA V2.27 005BYPS
Unit: MCU version: MTCE_MX2_V2.83_1

Please guys help me out because I am fighting with this chinese **** almost 2 weeks now
Hi,
I know it's a long time since your post, but I just installed an Android Head unit in my Peugeot 508 with JBL Sound, and the decoder I received was one for Peugeot 407, maybe that's why it's not working?
Also I cannot see your photos, they are most likely not online anymore.

Car builtin display shows "mute" on audio menu after installing Android Unit.

Car builtin display shows "mute" on audio menu after installing Android Unit.
I installed this radio, it works, steering wheel buttons work. Only thing is the display audio menu in the car shows "mute" regardless of what channel is in (FM1, FM2, DVD, AUX etc). The radio is not mute. The canbus decoder is connected. Any idea?

I had something similar a few days ago.
In my Joying I have with the steering wheel buttons in third party apps problem. Then I have to test the CAN BUS adapter infected by the Old Joying radio. After a After a restart I also had Audio Mute. However, the buttons and knobs on the radio were no longer synonymous.
In the radio app, I could not select a station.
Then I exchanged the CAN BUS adapter again and then it ran well.

Sorry but I don't think I understand what you are saying. Do you have a mercedes benz with cluster display that was showing mute or what? Also, you changed the can bus, you mean the canbus decoder or a setting in the radio? My unit doesn't have access to factory settings menu.

I have a VW and there I exchanged the canbus adapter. After that, I had the problem that I no longer had an audio output. Mute was displayed on the car radio with me.

PX30 Android steering wheel control problem Opel/Vaukhall Corsa C

I 've recently bought PX30 Android 8.1 multimedia for my Corsa C /2004-2006/.
Everything is functional except two things: no vehicle info readings and steering wheel controls are not working. There are three buttons on left and right rudder, on Steering wheel APK only volume up and down are shown on the right rudder are shown and I cannot assign any key.
Under factory settings on multimedia right Canbus is choosen and steering wheel assign button option are enabled.
And worth mentioning when I installed reverse camera I tried to connect reverse detective wire that goes along RCS video cable on the headunit side to connect to reverse detective wire that comes out of the canbus and camera didn't work. I got camera functionality only when connecting reverse detection wire with corresponding wire from headunit.
AliExpress told me I need to conect KEY2 wire that goes from headunit to SWC wire from native powercable for car stereo but I haven't managed to detect that wire. On wiring diagram for factory radio there is male connector for power cable that has pins for RSA SWC and RSA GND but on the corresponding female eurojack connector powercable there are no corresponding pins only empty plastic holes.
Any suggestion, I think that Canbus is faulty because it's not reading car information or I need to rewire cable connections ?
Thanks

Those are pics, last one is seller suggestion for rewiring which is impossible with available wiring diagrams, does anyone knows which pin from circled square handle SWC?
I think that Canbus is faulty.

8227L FM radio app and steering wheel control

Hello everyone!
I have simple question regarding SWC buttons mapping and switching radio stations by SWC.
Im using a resistive-based SWC controls connected to head unit by KEY-1(or Key-2. dont remeber, but there should be no difference at all). And I mapped << and >> buttons on SWC to the buttons in applicanion as in the picture below. There no other options for 'next' and 'prev' than those in red circles, so obviously I used them.

And it works very well with built-in MP3 (and video) player - switches next/prev song or video correctly. So absolutely no issue there - works as expected.
But using SWC witch FM radio app seems to be a little annoying.
There are 4 buttons to switch radio stations with built-in app:
RED - switches between stations saved in memory (white). To save stations in memory I have to use 'Search' button(GREEN) and takes several seconds, because it scnans whole FM range, 87 - 107 MHz.
YELLOW - Scans FM frequency till finds next (or prev) stong FM signal (radio station). In other words those buttons works as original bmw head unit. And this is what I would expect by using << and >> buttons.
Unfortunately mapping next/prev buttons[ like on first pic] actually uses functionality of RED ones. And its annoying because if I do scan, then drive another 30-50 km there will be for sure only noise on most of saved stations.
So, I think that I explained what I meant. And there are 2questions from me.
1. I assume there is no way to change SWC mapping in existing fm app. Is available other FM app where prev/next works as YELLOW buttons?
2. How does it work in your head units? (using steering wheel control only ) does it cycles through stations in memory? or quick scans till next strong fm signal? what kind of SWC is used in your car - resistive (key1, key2) od data-bus like CAN etc?
Thanks in advanc 4 feedback!
It doesn't matter if you use key1 or key2 to connect SWC. Some cars have key1 and key2 because they have buttons on both sides of the steering wheel with separate circuits.
The problem is just your radio app doesn't handle the next and previous events according to your needs. The radio app is extremely hardware related and part of an huge main application building the bridge between Android and hardware. So I think you won't find a radio app according to your needs. For me that was one more reason to use a DAB+ USB adapter and the app DAB-Z.

Junsun 8259 - Wifi and Bluetooth Issues

Hi,
1st time posting to the forum. I have recently installed Junsun V1 Pro 4GB+64GB in a Mazda 2
https://www.aliexpress.com/i/4000214865985.html
Unfortunately it is not working as expected and wondered if anyone else had had similar problems.
1. I can connect to a wireless network but cannot browse the internet. (Loading google.com take 5 mins for 1/2 a page (like worse than dial up speeds on a 500mb wireless network).
2. Bluetooth is connected to my phone however I am unable to play music (it is just garbled / intermittent. (Radio / Playing music from a usb stick works fine).
3. Before of 1 and 2 and I am unable to get CarPlay to work (which is why I bought the unit).
The only wire I haven't installed is the 4G Antenna (As I don't have any use for 4G In the device).
Original the device wouldn't save settings (the time manually set would be lost etc) so I have updated the MCU which has now resolved that.
I have attached Photos.
I have changed the BT Mode and set the name etc but this has made no difference.
Any help would be appreciated as currently waiting for Junsun to reply (been two days now)

Did you connect the camera connector with a yellow RCA plug, two small blue wires, and a long pink one? These are antennas for the Bluetooth and WiFi; I hadn't installed them when I first dry fitted the unit and noticed poor Wi-Fi reception.
Picture in this post for reference.
