8227L Chinesse HU android 10

Hi everyone. I have a 8227L HU, android 10, 10inch for vw passat, full touch, chinesse, from Junsun, aliexpress.
I had some canbus problems, and the seller gave me the 8227L-8.bin file to update, now the canbus problems solved, but the radio tuner application is stucked, i cant change the stations, and i have no sound on radio. I tried to make the settings in factory service mode, but nothing. I think the firmware is not ok. Can someone help me with some advice? Or a firmware that is suitable for my device ? Thanks a lot.

If it worked on the previous IOS version then this is obviously an Apple issue and you should consult the Apple forums.

tnx.problem solved
Hi I have the same problem and tried the fix in Hal9k topic without solving ... It seems my Dasaita PX6 can't find the iPhone hotspot, but if I open Settings-> Hotspot then the Dasaita finds it and connects immediately ...
With Toyota Touch 2 with Go (original equipment) I never had any problems, as soon as I started the car within 20 seconds I was already connected without doing anything ... We are talking about 3 days ago, before mounting the Dasaita, in the meantime there wasn't any iOS updates come out so nothing has changed in the phone.

Question FYT/SYU UIS8581A android 10 headunit - obd2 doesnt work with canbus decoder connected - plz help

I have lately installed an android headunit purchased from a local reseller on my Mazda CX-3 2018
the unit needs a canbus decoder to interface with the original car settings. and everything working fine besides the OBD2 port
when the canbus decoder is disconnected - obd2 works (connection to ecu is succesfull)
once the decoder is connected - all car canbus stuff work , but obd2 stopps working! - getting power but cannot connect to ecu
after going back to the seller he found out that the harness that is connecting to the canbus decoder is sending both canbus info and obd2 on the same wire (wtf!??!!?)
we found a single wire thats when connected - allows canbus connection to the headunit but kills obd2
once disconnected - no canbus to headunit but the obd2 returns to life..
Did anyone encounter such an issue before?
this is the closest product to what I have that I was able to find online -
8core TS18 UIS8581A android car dvd radio video radio player stereo with DSP apple carplay auto 4G sim card
www.alibaba.com
p.s if more info is needed ill be happy to provide it
thank you
I would have thought the error was either in the canbus decoder or the car's own canbus. Which Canbus decoder have you been supplied with, if you google its name and Mazda CX-3 do any clues come up with others having similar issues.
Sometimes these Canbus decoders work better with the head unit set to a different model or year. So pick another Mazda model or year of CX-3 and see if the issue is fixed.

It seems to be a general mazda profile... Photo attached
I can try to select other car manufacturers, but do I need to stay within BNR manufacturer ?
Can it be possible a special decoder is needed for my car model?!
Google came up with nothing that sounds similar..

I have an atermarket android head unit installed that needs canbus decoder to control car steering wheel buttons and all other canbus related stuff
it is enough the original car harness is disconnected from the decoder and obd2 works

I had a failure while installing the android screen in my Mazda CX 3. Then I removed the original Mazda DVD connector that was still connected and the result is that everything works fine

Yes, the DVD and monitor are separate. The Mazda unit consists of 3 parts including monitor, dvd, radio & amp. when the acc is active the ecu will read these 3 components, whereas when we plug in the android monitor we unplug it and connect the cable for the monitor and radio only then the dvd part is not touched at all, sorry my brother used translate it might be a bit confusing my words

I believe I understand you very good
I just confirmed the dvd player is connected
and is actually working with the headunit withing "car settings" app..
but I will gladly give it up for obd2 !!
Im taking the car back the the shop - they planned to get every available harness for the canbas decoder and test it one by one until one works 100%
I will ask them to try disconnecting the dvd

Disconnecting the DVD didn't help..
Any other ideas??

no I do not have a video..
but I think the issue is with the canbus decoder.
there seems to be a specific decoder model for this car model
the issue is the OBD2 port doesnt read ECU (it is getting power - and canbus voltages are good)
do you have a canbus decoder installed ?
if yes do you have an idea which model it is?
crimsonSP said:
tidak saya tidak punya video ..
tapi saya pikir masalahnya ada pada dekoder canbus.
sepertinya ada model dekoder khusus untuk model mobil ini
masalahnya adalah port OBD2 tidak membaca ECU (mendapatkan daya - dan voltase canbus bagus)
apakah Anda sudah menginstal decoder canbus?
jika ya apakah Anda punya ide model apa itu?

I've been using the BNR decoder canbus so far and have had no problems. when encountering problems, simply removing the original DVD connector immediately worked without problems

wow.. I was really hoping another decoder will solve it.. now im not so sure
is there a chance you can send a picture of the decoder? (fully understand if it a hassle.. )
are you using the mazda-all-all preset for BNR ?
oh I think I may be still using the mazda amplifier.
I have not installed an aftermarket amp and some cables are going to a harness on the passenger side which I believe is responsible for backup camera and speakers
have you disabled this also ?
crimsonSP said:
wow .. Saya sangat berharap decoder lain akan menyelesaikannya .. sekarang saya tidak begitu yakin
apakah ada kemungkinan Anda dapat mengirim gambar decoder? (sepenuhnya mengerti jika itu merepotkan .. )
apakah Anda menggunakan preset mazda-all-all untuk BNR?
oh saya pikir saya mungkin masih menggunakan amplifier mazda.
Saya belum memasang amp aftermarket dan beberapa kabel akan dipasang di sisi penumpang yang menurut saya bertanggung jawab untuk kamera cadangan dan speaker
sudahkah Anda menonaktifkan ini juga?
