Can-Bus decoder not working?

Hello all,
I have a KGL1, 1024x600 RK3188 unit and even if the controls in the steering wheel work propperly, I am missing the part of the "FIS" screen (I have a SEAT-VW car group) where I could see radio stations and song titles.
After I installed this navi-radio, the screen became completely black and is not showing that information anymore, that was previously shown with the original "standard" radio that came with the car.
Do you know if is it there any solution for this? or it will be always like this?
I attach a photo as an example from other car (the part of the yellow square), but the result is the same.
Thank you.

hello,
i think this is normal.
i have a vw too, and my FIS after installing a "non OEM Radio" only show me the same information.
my opinion is, the can-bus adapter can only read information from the car, there can´t write back or send information from the new "non OEM radio" to the FIS.
greets

I have an Audi with a similar display on the dashboard and I get some information displayed. There is a CAN BUS decoder installed in the wiring loom that I believe is supposed to be a two-way thing - i.e. you change the volume, track or radio station with the buttons on the steering wheel and these are interpreted by the head unit or change them on the head unit and they are 'supposed' to be sent to the cars computer. This partially works on my Audi, although the text that is displayed is wrong or interpreted wrong; only the Radio band and frequency are correct. I think the CAN BUS unit 'tells' the car what is happening (i.e. its a music track or its a phone call), however I think the car is expecting some more information regarding the details - i.e. PHONE + Number or Contact name, or USB Audio + Track number/details.
I think this is down to the software on the CAN BUS unit - but I am still learning.... I haven't seen any details of updating software/firmware on the CAN BUS adapters?

Thanks a lot to both of you.
@ADB100, how did you managed to make it working? For me in the upper part of the FIS, nothing appears and if it could see the radio station, something is something

I didn't do anything other than install the head unit with the CAN BUS decoder already in the wiring loom. I previously had an Audi RNS-E unit installed and all the information in the DIS (Audi refer to it as the Driver Information System) worked - Radio Station, Phone Contact, SD Card track name. The wiring loom that was supplied had the quadlock to connect to the connector from the car and then a small connected to connect to the back of the head unit. There were then RCA's for the four audio channels (FL, FR, RL & RR) plus the CAN BUS box. The CAN BUS box had a label on it saying 'CAN BUS DECODER. For Audi A3/TT' and then a software version. Its all installed in the car now so I can't tell you exactly as I'd need to remove it. I should have probably taken a few more photo's before I installed it... It might be coming out anyway and the RNS-E going back in to be honest as I am not too happy with this Tonghai Create unit...

Some HU "write" on the FIS, and others not......mine don't, but Xtrons PF73AA3A do.....

CANBUS not working? - PX5 MTCE MX Android 8.0 Rockchip 4 GB RAM by Witson

Hello everyone.
SORRY FOR MY ENGLISH!!
I recently purchased an Android PX5 car stereo (MTCE_MX from Witson) the 4GB version with Android 8 for my Fiat Doblò 2012.
Exactly this car radio: LINK WITSON
My problem is : CANBUS DECODER (link)
I connected the cables, etc. .. by default, everything works. The fact is that the canbus does not give me the information I would like.
When I open the door I see an image that is the same as this LINK, but nothing else.
Looking for solutions on the internet, I saw that many have an app installed, such as "Vehicle (link)" or "Car Info" where you can see a lot of information (like this LINK image)
Is it an application problem or is my car the problem?
Thanks a lot

im missing these apps as well. i have mercedes canbus

@GianniDarkos is the canbus box the one you are using? Wondering as I would expect VW-SS-03 would indicate SimpleSoft and Volkswagen but not Fiat. Would expect if VW-SS-03 should be the canbus decoder version 01 VW (Simple) should be the right canbus setting. Have you checked canbus box settings inside Factory settings? Which one is selected? Vehicle link might not show up for all canbus boxes.

9212B Haed Unit in BMW 1 Series (E81)

Hi
I have an Android 9212B unit fitted in my BMW 120D (E81) which I had to reset after a car battery replacement.
Now the unit does not seem to talk to the car properly, for instance it now shows kph instead of mph etc.
Looking in protocol (CAN ID) section I cannot see any reference to my car?
Does anyone have any ideas?
Thanks
Mark
P.S. car was fitted with this when I purchased it.

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.
