Seicane 10.1 Android 8 2003 Accord problems

Hey guys, I recently purchased and installed the seicane 10.1 android headunit in my 2003 Accord. It has the integrated climate control buttons. In all of the reviews and videos I have seen, when making adjustments to the climate control, those adjustments (fan speed, temperature, air direction) should appear on the headunit screen. Since I first installed it, this function has not worked. I have made sure to plug in the small white cable which connects the tablet with the climate control circuit board. When I emailed seicane they told me to check that the Canbus setting was set to "116 Accord_7 (DaoJun)". I checked and it is set correctly.
They also told me to check the "vendor setting" and said that it is located in "settings- system information." I have checked through every setting and menu and can not find anything that says "system information" or "vendor".
They also sent me a new circuit board for the climate control in case it was bad hardware, so i swapped it in and am still having the same issue.
Also, on their website they say that the upper climate control screen (also displays the clock) should work, and it does not.
Basically, I'm looking for some guidance as to my next steps. Has anyone had these issues? Can anyone tell me where I would find the "vendor" setting in order to verify that the setting is correct? I am having a hard time even dealing with seicane because their english is not great.
I have pictures on my google drive but can not post external links until 10 posts. If you can help, please pm me and I can send the link through there. Thanks in advance guys/girls.

Do they refuse to give you your money back too? They tell me that it's too troublesome to return and then offered me $150 refund. Its absolutely ridiculous.

The sound system of my car is a premium one and the radio device must send some commands to the amplifier but it doesn't. Because of that, the gain is too high and little electric noises are perceptible. I have tried canbus options for Hyundai with suffix AMP and the sound volume becomes extremely high. That is not a solution but shows the correct canbus speed is not 38400 bps as set originally. I have read the correct speed for comfort canbus of my vehicle is 95 kbps, perhaps 100 or 125. In all case, is the same speed as Hyundais AMP type have. I think Nissan AMP types give similar results, and another third mark. I don't remind exactly other marks because the key idea is that the canbus comfort speed is not correct and it is also necessary verify all canbus codes and add ones for the premium amplifier. And, thus, the hardware seems to be ok. It is not useful to change it. It is an issue related to software.
I have asked to Funrover for a solution and I have sent them several informations as I have explained here. But they have replied only one time to evade. I think that people wanting to purchase a similar device must wait. I think this issue is related to Android 8.0 and 8.1. In all case, Funrover must give me a solution even if they must contact original software developers who probably work for many integrators. If Funrover doesn't give a solution, I consider that another clients must be select a different mark.

Did you ever manage to fix this issue?
I've just installed the same unit and have the exact same issue.

Nope, still fighting with seicane about returning it. You're in for quite the headache...

Oh no!
There's one piece of info I've found on that I've yet to try.
Check out this video:
https://youtube.com/watch?v=pPvaCGCaypo
The person had the same problem as us. In the description he explains how he fixed it.
Basically just try swapping the white and white black wire that go to the main harness from the climate controls.
Edit: Haven't tried it yet. Might be worth a shot
EDIT 2: I did it. I swapped the wires now and it works.

To anyone that has the same issue on the Seicane unit for the Accord 7 - model H221(L) etc.
I found the solution - in my original post below I pointed to the video of another person with the same issue.
In the video description they mentioned how they fixed it: By swapping the white and white/black stripe wires on the 4 pin connector that connects to the climate control board.
This image is linked to in the video, saying that it's how the wires should look after being swapped.

However, on my unit, they were already configured this way - and the climate control display was not working.
I tried swapping the white and white/black stripe wires in any case (Which results in their layout being the opposite of this picture), and this solved the issue.
So, it looks like there is a solution. And it's NOT software related.

Does yours Seicane head unit have similar problem with window defrosting like in the video?
https://streamable.com/qz9wr
The relay switch ON/OFF all the time, you can hear a "clik" sound.

No issues with mine. Worked as it should. I ended up returning the unit due to multiple other problems

I had this same problem too -- i'm one of the people in the comments of that YouTube video, who was troubleshooting with the OP.
I'm surprised that Seicane is still sending out cables with the TX/RX wires reversed... Still haven't figured out how to change Celsius to Fahrenheit though.

I've also mounted a Seicane H221 on an Accord 7 (2005) and I'm facing some issues.
MCU version: MTCE_HF_V2.96_1
Build number: px5-userdebug 8.0.0 OPR5.170623.007 eng.hct.20181102.112849 test-keys
Regarding climate control, the car is equipped with dual zone. When first mounting the head unit, I was using the provided Y-cable which is in case for single zone AC. Re-mounting without the Y-cable solved the issue.
I have still some issues:
1/ Important: Climate control OSD work, buttons works but temperature is definitly not managed correctly: erratic temperature, too cold, too warm, fullspeed fan while temperature difference between requested and actual is 1deg C, etc...
2/ Less important: head LCD display is now blank (no temperature, hour, ...)
3/ Behind steering wheel LCD display do not display temperature
I suppose these 3 issues are somewhat linked to CANbus management. First, I'm wondering if I should consider upgrading the MCU firmware (MTCE) ? Android ? CANbus protocol ?
I've read Hal9k bring some improvements on these units. Has anyone tried upgrading Seicane H221 with this ROM ?
Thank you in advance for your answers !

Anyone know how to get into recovery mode?
Any ideas about how to get into developer's options, I'm using Android 9 and pressing build # 7 times doesn't work.

hmm, i have bought the same android unit from seicane, this one came with android 9 , and somehow i cannot get the airco display to show up.
I did already try the connector cable swap ( white <--> whiteblack ) , but it doesn't seem to do anything.
I am also wondering, the unit doesn't show any lights on the buttons, so i am unable to operate the a/c in the dark.
is that by design, or should there be lights in the buttons?
Does any of you guys have any suggestions?

I have similar issues to some of you guys on a Seicane unit in my Australian Honda Accord Euro 2007 - I believe this is the same car as the US Acura TSX.
1) The air con controls keep popping up on the display every couple of minutes even though I'm not touching any of the physical buttons/knobs.
2) The outside temperature reading has disappeared from the instrument cluster behind the steering wheel
This is the unit I have:
I'd love to know if anyone has any potential fixes!

Thank you this worked for me everything pops up but in centigrade unfortunately. I also lost the outside temperature on the gage cluster. I also noticed the fan speed was pretty slow and the duel buttons and heater buttons do not work. My unit had a very noisy display and now it changes colors and goes crazy Im wondering if it is another wiring problem. I also have a way that you guys can put android auto on it. you can get the headunit reloaded apk and once you do that Android Auto works perfectly.

since the wire swap was not working for mine, seicane is sending me a nuw board + new cables...
I'll update if this is a solution, however, i doubt it.
ps: the customer support isn't that bad, the only problem i face is, the don't understand english
you have to be very specific and don't use complicated words.

You can choose F in factory settings iirc

Hello! I have the same Celsius to Fahrenheit settings issue with my Seicane. Were you able to figure that out? Want all displays/settings to be in Fahrenheit. Thanks in advance for your help.

So i got the new board and installed everything ...
and guess what, as expected it wasn't working, still no airco diplay.
so i went to my car dealer and he explained to me that i have a kind of freak car.
in the states it would be sold as an honda acura tl , but it was built in the UK . i have one of the first cars that came from the production line, and i think they changed some things along the way.
apparently the radio is the only thing different from the acura. it is the same as the normal accord 2003.
so he told me to look for a can-bus setting for the acura.
I couldn't find any, but in a last resort i found a canbus setting 120 "accord 7 'long chinese name' 2 "
as the board i have is version 2 i thought, let's give it a shot.
and upon reboot the first thing i saw was, in the upper right corner, i suddenly had the outside temperature displayed
i knew it was good and indeed it was. i now have a fully functional headunit.
i have no clue if this board swap was needed, maybe not , but it doesn't really matter, it works, and I'm happy.

Need Help To update Seicane Radio

I recently bought me a unit from Seicane and was trying to update it hoping it would fix my problem of it wont work with my A/C like I dont get any type of animation that tells me the temperature so im hoping updating it will fix it. Does anyone have any idea on where i could find an update and the process to update it and does anyone have any idea why my radio is no showing the temperature animation. When i do auto it comes on like it should, i can control the power of the fan as well but when it comes to using the knob to get it to a certain temp. thats when i start facing problems.When talking to the person that sold it to me they said i was suppose to go to canubus and manual input the A/C settings but i do not have that and the picture they have to help has a different interface than my unit reason why i feel like i need to update. Can some one please help

i faced a lot of issues with it , but in the end, it was probably just the canbus setting + the cable not connected correctly( or the board was broken not sure of that one)
Make sure the 4-pin cable is connected to the air-co part ( it comes out really easy so after you installed the head unit, make sure that the cable is still there , you should be able to feel it if it is there
after that ; you should have settings --> car settings --> factory settings
( password for that is 126 )
then go to canbus and try all the different canbus options for your honda there are.
If it works ( i noticed it immediately) you also have the outside temp listed in the right corner of the screen
here the images of my unit
first image; the 4-pin cable , photograph taken while the unit is in the car. camera between the unit and the bin below that

2nd how to get to canbus settings ( "instellingen" = settings ( sorry, i went with my own language for this unit)
go to factory settings and type pin: 126
this is how mine is currently configured
those are all the canbus settings could find on my device

I made an account just to say Thank you so much for this post Pjottrr, I was going crazy because I bought an off brand, off brand cheap Chinese unit that has no brand what so ever. the dudes I bought it off of were talking circles when asked about the isssue. But the solution was to change the CAN BUS to 123 accord. That was the one that worked for my 03 accord dual zone climate control settings. As far as the conversion to Fahrenheit that’s easy F = C*2+30
Edit: I didn’t have to change any wires. And that wouldn’t have helped either way. My wires are white, pink, black and yellow

Hello everyone. I received an updated Firmware directly from seicane for their head unit. This is Android 10 update for the 2/32 GB unit. Everything seems to be working great so far on unit. If you would like to try it for yourself please feel free to download and install. I'm not too tech savvy so if you have any questions I'll answer them the best I can. Thought I would share for anyone to update their own unit if possible
PLEASE BE ADVISED YOU USE THIS AT YOUR OWN RISK!
I will not be held responsible for any damages done to your own unit.
Thank you!

Ford Fiesta Steering Wheel buttons not working

Hello everybody, I really don't know who to ask for help so I hope I am in the correct area of the forum.
I recently replaced the radio on my European Ford Fiesta 2011 1.2L Petrol with an Android unit from Aliexpress. The unit is the one here:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Unfortunately the only thing that doesn't work are my steering wheel buttons. I only have a set of them placed on the left side of the steering wheel.
This is becoming annoying, especially because today I almost run into a car accident while decreasing the music volume on the unit itself.
Now, Aliexpress doesn't want to refund or replace the product, because according to them it should work straight away. But I remember that when I ordered the unit there was a customer comment saying that didn't work for him as well, but he fixed it doing some rewiring (I remember mentioning pink and brown something like that. Unfortunately the comment has been removed, and it was in russian). Obviously I tried to connect pink and brown together and doesn't work.
I will add the pictures of all the connectors, I managed to find online the pinout with all the wiring colors. The unit came with some kind of CAN decoder, what's written on the label is:
P/N: FORD-RZ-11
SW: 0003
HW: GM-ND03
FOR: 09-12
(190216)
The rest is in Chinese, the QR code doesn't work and if I search on the internet I cannot find anything.
I have also draw a diagram showing the wiring between this box, the main car connector and the back of the radio unit.
Can someone please help me with this issue?

Suggest having a read through the forums, you'll find alot of discussion on your topic.
Reading might help you understand the issues involved and help form directed questions along the way.
I dont understand the comment around 'aliexpress doesn't want to refund or replace' because the issue you experience is exactly what the aliexpress dispute process is for. Use it.
I've requested mods move this to Android Head units as this isn't an android auto topic.

Thanks for asking to move the thread to the proper section.
I have been reading online for 2 days and I cannot find any answer to my problem. All I know is that my problem is electrical, I am 100% sure about that, I just don't know what to cut and connect together.

Update.
This morning I went in the car and cut pink and brown wire.
I then connected all together pink (SWC1) + Brown + White/Green (SWC2). Doing so when I do the pairing of the buttons on the device I can see that the buttons get detected but still doesn't work. It look like something is shorting and making conflict in the unit.
Now I know that the user feedback on aliexpress was right, I do have an electrical issue and I need to cut and bridge a wire, but I don't know what.
Is there someone good in electronic that can review my connection scheme I made above and help me out? I am willing to pay a beer

Hi
I am having the same issue as you with mine
Did you manage to sort this or could you help me with getting it to recognise the steering controls
Which wires did you wire and what did you do?
The pink wire and brown wire both seem to go into something

UPDATE
UPDATE:
After messing about with the wiring and doing some research i figured out how to sort it and it worked for me. I had to cut the pink (SW1 wire) and connected this to the pin 10 black (GND) wire from the Connector x1 using some old cable to make it longer and connect them together , this gave a different voltage each time a button was pressed and in the steering wheel learning app it recognised it and i was able to set it up, so far it is all working.

I'm currently facing the same problem does anybody have pictures from a working set of connections? or a diagram?
Thanks in advance

Al zo steeringwheel problem
I have the same problem. Does anyone have a picture of what i must change?

I have the exact same issue, a few pictures detailing the solution would be greatly appreciated.

Hi am facing the same problem does anyone has any pictures of wiring

Thecproblem on mine is that when i connect the canbus wire on input D .
The volume goes mute and back to normal again and doesn't let the radio work properly.
Any knowledge appreciated

Hi man no i haven't solved the problem yet .any help appreciated.

Can you provide a few pictures of your connectors?

Hello guys.
Like you I have problems with SWC, also I have only Key 2 wire ( Blue/White) and nothing else no pink wire, seriously I'm lost. Seller in Aliexpress have no idea about what I'm asking. I tried everything wiring cables to each other in all possible combination , I'm tired and in lack of ideas. If someone had resolve the problem I appreciate any help.

When I fitted in my car, I use the RCA outputs connection cable driving a processor and then the amps, it would make a loud thumping noise through the system whenever I changed mode on the screen (see Youtube video https://www.youtube.com/watch?v=aHNONRLvbPU). It does this on the bench test as well.
Sound through the normal speaker outputs is clear and without any problems.
On investigation with a multi meter, I found that every time I changed mode, the power Amp Cont. supply would switch on and off, thereby creating the thump through the speakers. Even if I use the antenna power supply which is constant even with mode change, it still thumps, as RCA outputs convey the on/off thump of the AMP Cont through them.
After referring this problem to the seller, he said it was a mainboard problem, and I returned the unit which he exchanged for a new unit. However, the new unit has exactly the same problem ( it was a new unit, as I made sure of certain markings on the returned unit).
Seller sent me a Software Update, which did no changes at all!
The seller then finally informed me that the AV cable adapter RCA out and Amp. Cont. connections are not compatible with this unit, software problem, even though they give the AV connector together with the unit!
Has anybody had a similar problem with a similar unit?
I have tried changing various parameters in the factory settings with no luck.
Could it be a simple setting adjustment with the unit which not even the seller can help with, as in the end I will have to return the unit.
I could use a high low converter which ultimately degrades sound further.
Would appreciate any input. thanks.

Firmware update
I have the firmware update for this Junsun V1 2020 unit as well if anyone needs.

I’ve got the same branded unit, 2gb+32gb Junsun V1. on my car the antenna power is retained from the original head unit and I’m not using amps at the moment so never tested the outputs on mine to compare.
Firstly I would try wiring the remote wire from the amp to a permanent 12v feed to see if the thump still happens.
If it goes away it’s up to you whether you want to send it back as it’s clearly not “right”, personally I’d rather keep it and try and find a switched live in your car to power the amp remote instead, or use the amp output from the Junsun with a relay rather than connecting to the amps directly.

Hello
Have tried that. Wherever you give remote power for the amps from, the thump unfortunately is carried through the RCA's from inside the unit from the mode change. It causes an on/ off in the Amp Cont power, and the RCA's out pick it up from the mainboard of the unit. Have thought of maybe sourcing the RCA outputs directly on the board before they reach the TDA7851L amp, but don't want to dive that deep yet

Not Android Auto, requested thread moved to Android head units.

No I don’t think I’d start digging that deep into the head unit just in case!
If it was mine the next thing I’d be trying is a ground loop isolator - would eliminate any grounding issues and also block any DC causing this.
I’m assuming the issue wasn’t present with your old head unit and only with the new one?

Have tried a ground loop isolator as well, but problem is caused by mode switching within the unit from Radio-Video-Music etc. which switches off the Amp.Cont power momentarily, and this is picked up by the RCA output stage. Cannot explain it?
So, it is most likely firmware/software related.
There is no noise at all when powering the speakers normally through the speaker outputs of the unit.
The 7' was a Hizpo and no problems at all for 3 years. The 9" model from Junsun, and the new replacement they sent have both the same problem.
Thanks

I'm not sure if it will be the same, but just send me a message and I will give you the link and screenshots of my units MCU data. I cannot post external links on the forum yet, as am new member still.
Thanks

RCA out
So after many attempts to solve this problem, I soldered new RCA outputs before the TDA7851L amp inputs, and now I have crystal clear sound to my processor and amps. Could not find any other solution, and the unit is pretty good.

dranias said:

Turns out i have exact same unit. All versions matches from the screenshots.
However, i had no problems with audio outputs. I have bought RCA connectors separately and have plugged external amp.
Sound quality is good.
Do you have any problems with outside temperature showing?
Mine is not showing when temperature is greater than 10C

This is a pretty cool solution, glad you got it working! Not sure why they didn't do this in the first place really, any negative effects you've noticed?

Nope, non at all. It actually has better sound than after the internal amp normal output.

Are you using Can Bus adapter on your car? I was thinking that may be the reason my RCA outputs don't work properly, as mine is non Can.
I remember reading on some other post the problem with the temperature, where they said you have to try different Can settings in the factory settings till you get the ideal choice. Not sure where I saw this post. Hope this helps.

Volume knob problem

I recently purchased a new 7 inch android 10 head unit. Rockchip PX5 (Klyde). All are working very well except one thing. My original car stereo had volume knob (i think it is called rotary encoder). That volume knob was working perfectly, until the time i installed the new head unit. After the installation it malfunctions a lot! I must turn it 4-5 clicks with specific speed just to increase or decrease volume by 1. If i turn it more quickly it doesn't do anything. I went to the shop i got it, he pulled out the unit, but he told me that i had put all the wires correctly. He didn't have any solution to my problem. 2-3 wires haven't been installed and left in the box, but the labels on them say camera,aux.... staff like that. They dont say something like volume knob or rotary encoder.
Any help would be greatly appreciated. I don't know what to do!! (sorry for bad english)

The seller needs to get in contact with Klyde (seems to be an official reseller, I hope) and ask for help.
As you did not buy it at Klyde yourself, Klyde would not be able to help.
The seller is the one who is responsible.
You won´t find any help here, because this is really car dependent and needs to be analyzed by Klyde in combination with the reseller.

Seller or one of his engineers must have a zip file / files to import volume and other knob functions to factory settings in order to work. Every device has his own update files that are imported thru factory settings / KEY / BUTTON menu (not touch learning - this is for touch screen functions).
When given specific file unzip them (it will be a few files inside) put on USB drive and plug in device then go to factory settings / KEY and press import, after import restart device and that's it. It should work

If i tell my seller to speak with Klyde he will laugh at me. He doesn't know him. I don't know him either! I recently learned that these unit are from one person named Klyde. The shop i bought it takes these units from another company named cadence that imports head units from outside greece. Anyway i spoke with cadence too, and they yelled at me because i installed the update. And they said i lost warranty because of that.
I will try to find the solution on my own..
I cant deal with these any more....

Please take an image of your factory settings and every menu in it please...

That will not help, because:
This knob is managed by the CAN bus and delivers a square wave which has to be interpreted by the CAN box.
If this is not fully supported, or wrong implemented (Even if the wrong CAN box settings are chosen) the volume knob does not react as expected.
2 things can help:
1. Check the CAN settings in the head unit. I fear you have the right settings, but the CAN box software is messed up. Escalate that to the seller (who ever this is) and if they are not able to provide that, give the unit back to them. You won´t get lucky with it.
2. Get the right CAN box for your special car (Citroen C4) from your seller with the right parameters configured.
To be mentioned here again: These French cars are quite difficult, because the manufacture often changes hard- and software during the production time.
I would try to get in contact with Klyde. If you tell them the whole story, may be they can help to sell the right CAN box for your special car.

I will upload photos tomorrow from the can bus settings etc, so you can see for yourself. I will call the seller one more time tomorrow. We'll see...

There is a picture shown where you read "Canbus key study".
Did you already tried to setup the key of the steering wheel and the volume knob in there?

Yes i already tried. It didn't change anything. I think that's because the volume knob already has the command to increase or decrease volume, but mulfanctions. What i did yesterday was to remap two keys ( the up and down arrows) for volume up and down. But i am still missing the good old knob....
