Hi,
I have an android head unit for my RAV4. I am not sure which exact model it is. It was fine for a year, until recently. The sound suddenly is gone. No audio coming out of the unit.
Contacted the seller (from ebay) but no response from them. The unit currently dissembled. It has a TDA7388 for the audio processor. I have a recollection that the unit is from ATOP company. I could not find any information regarding that name.
I read that on joying has a fix for similar issue, by bypassing the audio fuse.
Any help is appreciated.
Thanks.
I have some pictures. How do I attached them here ? Thanks
I am having the same issue. Everything worked fine for about 2 months then the audio stopped working. I am working with the seller "Kunfine" who had me flash the unit but that didn't fix the problem.
search Youtube for the Joying fix " Joying Android car stereo How to soldering when the head unit no sound? " (sorry no link as I cannot post them yet).
Seems logical that a fuse could be blown but illogical to bypass the internal fuse. Poor engineering I guess. Mine is still under warranty and hopefully the seller will make it right for me.

I had took everything apart. Trying to find that 'fuse'. Mine is not Joying brand. So far, no luck finding/bypassing the fuse. The seller gone mute on me. Found another seller that sells ATOP brand. And she also refused to help.
I was hoping that I can find some help from the forum.

I had something similar with my KLD unit, it dropped sound completely while i was driving
I had just updated the MCU so on getting home i reverted back and all ok since.
Have you made any firmware or MCU updates?
I had the latest firmware from the seller, not the manufacturer. I could not find anything ATOP related.
On the version page, it says
CPU information: Cortex-A9 dual core
RAM information: DDR3 1GB
Android version: 4.4.2
MCU version: 4.3.7-14-10-600101
System version: 2.8.9

Hi,
I'm owning a MTCD unit since a few months now.
During that time it happend to me 5 times now that my car battery was drained after 2-3 days without driving.
This seams to happen in infrequent intervals. As I've been on vacation for 2 weeks and the car was parked at the airport I had no problem at all.
I started a little bit of investigating and this is what I found out.
The unit (or the CAN bus decoder) seams sometimes to occupy or block the CAN bus after shutting down.
This prevents the car's controllers to enter sleep mode. So it's them which drain the battery, not the radio itself. But it is obviously caused by the can bus decoder inside the radio.
Has this happend to anyone else?
Does anyone have a fix or any suggestion for me?
Thanks!
Maybe you have to switch the red power cable with the yellow cable in the ISO connection...
If you think it is related to can bus you can try to deactivate it on factory settings or simply perform a mcu update from your manufacturer/seller.
The mcu is the responsible of managing the can bus decoder

VW cars don't have a wire which is switched by ignition anymore.
Power on/off is only managed through can bus.
Regarding the mcu update, thanks for the hint, I will try to contact my supplier.
Sounds like you're on the right track. Just figured I'd throw in that I have a 2013 Mazda 3 and I had major problems with mine. Tracked it to the canbus, and switching the two wires seems to have fixed it. I realize that VW is different, I'm just posting this here in case other people have the same issue.
I have a similar problem with an MTCD with inbuilt CAN BUS controller in may 2008 A3
The only fix I have been able to find is this possibility - see post # 8

Hi,
thanks!
Sounds like exactly the same issue. And their solution seems to be the same which I was thinking about.
But I wanted to avoid cutting wires of the quad lock plug. Think I have to reconsider that.
You could try using something like this

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.

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.
Hey guys!
I'm hoping you can help me out with some issues I've got with my Android head-unit.
The model is a NAVD-MT049 for an Audi A3.
It's got the reverse cam installed, and for a while now I've been having issues with the video feed.
I've noticed that sometimes when I switch in reverse the camera first displays No Signal, and then after a minute or so it starts working. This happens almost everytime now.
Any tips on what could be the issue?
The wiring is done as it should be, and I've been using it for 3 months now.
Do I need yo get an MCU update?
I've read that on some models this can solve the issue, but I haven't found a website where I have the compatible version for this unit.
Any feedback is welcome!

Hello,
I am currently facing issue to get positive voltage from android unit to camera. Any one faced this too? Any solutions to get that Red wire named "ACC" to get voltage on?
Suggest best to seek assistance from a reputable local installer.

To be honest:
If you even don´t know what is meant with ACC, keep your hands off from installing the unit.

Bro I completely understand, even in scheme its shown to plug camera there, 0volts after ignition or vehicle turned on. Thats the issue.
