No, I have a an RCA out that sends a PCM signal. I got an RAC male to male cable and cut one end. Then joined the bare wires to the SPDIF cables in the car wiring loom. Took 10 minutes and problem solved.

For your unit, open it and look on the motherboard for some headers for RCA out or any audio signal out. You might get lucky and that you have a newer motherboard and the manufacturer just did not pay for the RCA out plug in the manufacture. I did take a voltage reading of the PCM values and put them in a post somewhere. I can't remember what they were, but there wan't much voltage.
[Android Head-Units] rogierg:
@ludditefornow no the unit does not have spdif out, checked internals using a flashlight and there's no headers for the spdif output. In the meantime I have purchased a cable that comes with a line to spdif conversion box which I installed but still it does not work.

Is the external amp always on if acc is on or is it enabled through a canbus command?
[Android Head-Units] TorstenH:
I think the amp will get its power from the original OEM head unit / radio.

Google for the pinout of your OEM head unit. This will allow you to identify the wire which is used for amp power supply.
[Android Head-Units] rogierg:
Thanks for getting back!

But no: the only connections between the OEM head unit and amplifier are spdif and canbus. Probably the volume and panning commands are sent using this and likely the power on command too.

The amp is directly fed from the battery. It also has an acc in so that may be used for turning it on.

I believe the spdif converter I have received is borked. I measured the outputs using a multimeter (DC) and they all show 5V. Which sort of makes sense since the spdif signal is modulating between 2 and 7 volt. If only I had an oscilloscope, I could make sure!

What is strange is that the GND pin is also at 5V. I've tried disconnecting the GND connection, but this makes no difference.
[Android Head-Units] TorstenH:
Why are you not connecting ACC if the amp provides this input?
[Android Head-Units] TorstenH:
According to the first post the OEM head unit has a remote AMP output which gets used to provide the "turn on" signal to the amp.
[Android Head-Units] TorstenH:
Here is an example with a separate Amp On wire:
[Android Head-Units] rogierg:
@ludditefornow I have one more question about the spdif connection in your car. The RCA output is "regular" spdif whereas my cars external amp takes differential spdif. (There's a spdif high, low and gnd) was this also the case for your car?
[Android Head-Units] ludditefornow:
What are the wire colours for them? My wiring diagram only showed a hi / low or +-. Can't remember which. I have the info somewhere in here. I haven't thought about this in a long time.

Have you considered just connecting the +- or high low and seeing the result then reversing it to check that result?
[Android Head-Units] rogierg:
ChatGPT suggests connecting the signal pin to high and gnd to low. In that way the voltage difference might be enough to work. So I'll try that next.

Olá! Os detalhes do ar condicionado aparecem na unidade principal?

Mod translation: Hello! Do air conditioning details appear on the main unit?
[Android Head-Units] ludditefornow:
The air con details do not appear on screen for me. Also, the outdoor temperature feature does not chow correctly. The open door feature does not work either.

This may be due to the programming of my canbus module that I received with my head unit.
[Android Head-Units] marcelocandido:
"Eu tenho um Cadenza 2011 e, quando instalei uma unidade Android, até o dia em que perguntei se as informações sobre o seu apareceram, o meu também não. Fiz todas as configurações possíveis.

Mod translation: "I have a 2011 Cadenza and when I installed an Android unit, until the day I asked if the information about yours appeared, mine didn't either. I did all the settings possible. About 3 days ago I discovered that I had to update the canbus, I updated it, and it started showing the air conditioning and outside temperature information. Have you already done this update on yours?"

The Kia Sportage 3 (2010-2016) does not have the body/chassis canbus (B-CAN) connected where the head unit is (at least every regional model I've researched). Many wiring diagrams label it as being there but it is not.

It's only a media canbus (M-CAN) that's connected on higher spec models and it's only used to tell the amp to turn on and to control the sub woofer.

The canbus box for the car (I use a SimpleSoft XP HY-SS-04 but they all do the same) only controls the amp, sub, sends a reverse trigger (but this comes from the reverse wire not a canbus message) and it translates the SWC which are often digital in Kia's and not resistive.

Doors, reverse sensors, tpms, external temperature, etc, are all transmitted on the B-CAN which isn't present near the head unit. All that info is shown on the instrument cluster to which the B-CAN is connected.

The air con is not connected to the B-CAN of the car. It's only usually connected to canbus on cars that show the air con on the cars original/OEM head unit.

Teyes/Mekede actually have a note on their page for the Sportage 3 about it.

The bit in bold interests me. I've been tempted to hook up a twisted pair to the B-CAN and see what happens. The B-CAN is connected to pins 34 & 35 (red and blue) of the 40 pin connector that connects to the instrument cluster.
[Android Head-Units] ludditefornow:
Why do you hypothesize will happen if you make that twisted pair on pin 34 and 35.
[Android Head-Units] j0hn83:
The Chinese say they have full canbus info for Kia/Hyundai. The issue is that the necessary Canbus isn't connected to the head unit. I'm going to connect it.

I reckon there's a 99.9% chance nothing will happen.

In an ideal world though my canbus data (reverse sensors in particular) will show up on the head unit.

I have no idea how these canbus boxes work. I don't know if they just convert all canbus/hex data they receive to UART and let the head unit decipher everything or if the canbus box needs to know each and every canbus message to translate it to a specific UART message that the head unit understands.

1 scenario gives a chance of my experiment working, the other not so much. I can't see the canbus box manufacturer going to the trouble of adding protocol info the car doesn't even send.
[Android Head-Units] Spoetage Driver:
Nice project that you are doing. I've already thought about this. If you are successful, please provide exact details of where what is connected. Thanks

Hello Torsten, I found this topic because I have actually a problem.

My rear view camera is constantly ON when my handbrake is OFF.

My rear view camera goes off on Android Head Unit when my handbrake is ON.

A brown cable which is at C1.C2 (of my wiring diagram) stands for PARKING and goes from my Car interface to the SIMPLE SOFT CANBUS.

A purple (with card called REVERSE) cable which is at A2 (of my wiring diagram) stands for DIRECTION and goes from my Car interface to NOTHING (it is not linked).

www.manualslib.com

Do you have any ideas what is the most logic way to solve this?
[Android Head-Units] TorstenH:
Looks like the can interface interprets the signals not in the right way. First you could try to find a working can config in factory settings. Make photos of the current settings before changing anything because there is no "reset to defaults".

Your car should provide 12V+ on PARKING wire while handbrake is ON.

So it's confusing me that it's not the other way round. I would expect...

Handbreak ON -> Rear view ON
Handbreak OFF -> Rear view OFF

instead of

Handbreak OFF -> Rear view ON
Handbreak ON -> Rear view OFF

You may find a can setting which prevents to turn on/off rear camera besed on handbrake status. If not you could disconnect PARKING from the can interface. I would prefer to unpin the connection instead of simply cutting it (to make the change reversible).

First we need to get rid of the relation to the status of handbreak. Then we can rewire DIRECTION to be the trigger for reverse cam.
[Android Head-Units] Rickomode:
Maybe I'm saying something wrong but maybe it could the handbrake is giving an constantly power and when I pull it the signal goes to zero (because all need to power to zero because we can not move drive with the car.

(I do not know why)

I used before the old OEM navigation and when I set the reverse gear it switched to the rear view.

I received canbus and a fully cable tree from the manufacturer. I contacted him with the problem and he saying: The handbrake signal was inputted as reverse signal, causing you to pull the handbrake and switch the display screen to reverse gear.

He told me to connect a BROWN wire which come from the Android Head Unit TO the purple REVERSE cable and this one (should) give me the POWER when I put it on reverse. (it is connected on the DIRECTION).

I do not know anything about it and I should believe him, but do you think this could help or not?
[Android Head-Units] TorstenH:
Your seller is right if the reverse cam gets shown as soon as you activate the handbrake. But you've written:

"My rear view camera is constantly ON when my handbrake is OFF".

I interpreted "handbrake" is OFF with "not active" and so you will see the camera picture constantly while driving.

Let's first get rid of this confusion and let me know if the camera gets visible with active (enabled) or inactive (disabled) handbrake.
[Android Head-Units] Rickomode:
Check the video:
[Android Head-Units] Rickomode:
@TorstenH

BTW:: It does not have an electric handbrake (just an handle) and a automatic gearbox ( P, R, N, D ) .
[Android Head-Units] Rickomode:
Hello, I solved the problem.

I opened some cables from advice from the manufacturer and it was a rubbish. I was sure this can not be correctly.

The signal was given from the "PARKING" which is (thanks to internet and XDA Forums) the security signal for not make it possible to watch some videos/dvds and usual other things that is not responsive to do while driving.

Because that signal was giving non stop power when the handbrake was OFF (which is correct) it gives non stop power to the rear camera and the head unit. It was thinking the car was constantly in reverse.

I took all cables from them unlinked and linked the power cable of the camera (which goes in the head unit) with the "REVERSE" cable from my car interface.

The other cable which was linked with the PARKING and goes with the other side in the canbus I connected again.

The manufacturer told me to remove one cable from the tree which goes in the canbus but I was first of all trying to hold him in it (just unlinked) because it was giving an INPUT and without any power it is doing nothing.

Here a few pictures of the rubbish and the connections I made yesterday. After testing it all working and hopeful it will working for the rest of my (car) life.
[Android Head-Units] JonnoAnnells:
I'm currently stuck in the situation where I don't have any sound with my new head unit similar if not the same as the original post. I don't really understand what I need to do and I also have a different harness kit, does anyone have the links to what I need to get to be able to set up sound or even a diagram of how to wire up the coax solution or a picture of what it's meant to look like? This is driving me crazy at the moment
[Android Head-Units] Doomic:
This blog helped me a lot.

I have a Kia Carens. Received the wrong cable first, but with the new cable I got all things working (only the steering buttons did not work, but they did with the first cable, so compared this and checked it with the pinouts from the blog post).

The hy-ss-04 is translating the lineouts of the headunit to spdif.. only thing that is not working is changing the speaker balance from the sound settings (front to rear). I assumed the rear speakers are not working, but will check it tomorrow maybe they are just in sync with the front speakers. However I would love to see that working again. So wondering; anyone else having the same issue or is something wrong with my hy-ss-04 or wires?

Edit; rear speakers are working; it's just that I can't change the balance between front and rear.

Hello guys,

I bought a radio from Junsun 6gb 128gb. I have a kia sportage 3 2012 with navi radio (connectors type C).

The seller sent me cables for this version. After connecting all the relevant connectors to the radio, the speaker system, including the subwoofer, does not work properly for me, the overall rear system.

1. speakers: When I start music, it only plays on the front speakers. The rear speakers do not play. I don't know how to connect it. In the original radio, the original speaker connector was not connected. I have a Canbus, but I don't know what cantype I should put in there to make it work correctly. I tried various options that the radio offered me, but to no avail. Either my radio was not playing and the SWC buttons on the steering wheel were not working or the radio was playing and the buttons on the steering wheel were missing.

2. reversing camera: For unknown reasons, nothing works for me when I engage reverse gear. It won't even start with a black screen. Also, the sensors do not go to the radio.

Has anyone encountered these issues?

Do you know which canbus type is most suitable for Kia sportage 3 2012? Ideally if you write me the number. Now I'm using 14.10. This is "Kia sportage High vers. 2019"

Thank you for helping me
[Android Head-Units] j0hn83:
Unfortunately kia have about a dozen possible harnesses for the mk3 Sportage. The OEM stereo, and region the car is made in makes a difference.

Every single seller I asked about my unit (type C) would send the incorrect harness for my 2014 Sportage (with infinity amp, sub & reverse camera).

A good give away is looking at the 4 reverse camera pins on the kia end and on the harness sent by Junsun. Check if their position matches (it's a 20 pin adapter with only 4 pins populated).

I use a Simple Soft XP HY-SS-04 canbus box. I don't pick anything Kia in my head units canbus options. I chose XP / Hyundai IX45 / All / AMP for my canbus settings, though I don't have a Junsun so what you select might be slightly different.

In the end I had to buy my own harness. The harness I bought is this 1 here.

https://a.aliexpress.com/_EuvbeJl
[Android Head-Units] Michelloart:
I have the same canbus as you. But I don't have that option in the Canbus type settings. I can send you the video I sent to the seller regarding this problem.

But today I managed to fix the reversing camera using the post above. I also checked all the cables to see if they are compatible with the correct pinouts to avoid that something is not connected correctly. Now the only remaining problem is why my rear speakers do not play. I think the problem will be the AMP (amplifier).
[Android Head-Units] j0hn83:
Too many options to look at doing it that way.

Simplify things by select XP instead of ALL (you have an XP canbus).

The canbus box converts the headunits analogue signal to the amps digital (spdif via coax) signal.

There should be some rca cables coming out the canbus box that connect to rca coming from the head unit.

Does your unit have spdif outputs?
[Android Head-Units] Michelloart:
Yes, I plugged all the RCA connectors into the corresponding RCA connectors.

This Hyundai is for canbus XP. There is no option directly for Kia and specifically not for my model either.
[Android Head-Units] j0hn83:
That pin out you posted is nothing like mine.

Mine is identical (100%) to this page here: https://bluemarmot.ekibox.net/en/node/112

My Kia has an 18 pin and a 24 pin connector but my amp comes from the 18 pin connector. You show your spdif coming from the 24 pin connector.

That shouldn't make any difference as long as the provided harness feeds them all in the right direction.

I only connected 1x red and 1x white rca.

I ignored the aux rca as they aren't necessary.
[Android Head-Units] Michelloart:
I have a different cable than yours. I will attach a picture of my wiring with pinout. You have type B options for cables. I have type C.

This is how I have it wired. I did not draw the camera and other things not related to the speakers.

Or some application to create playlists from folders on Diamond?

Thanks

Hi. Decided to try to give some new life to this old thing. But when I install the TWRP thing and shut it down it immediately boots up and overwrites the TWRT. I know the instructions says to let go of the buttons "very fast", but I've been practising this for hours now and I'm pretty sure it's impossible to do it any faster. I did try to open it up but it doesn't look like the battery is very easily accessible, bit worried about messing around in there while it's turned on. I've been considering just letting it run out of power, but if you guys have a better solution that would be great.
[Galaxy Tab S General] sergegalun:
Slight status update. Tried to let the thing just run out of power, but it didn't work. Then I found out that the key to restarting it properly was to boot it back into recovery mode before it has time to automatically reboot. So I've taken care of that part. But it seems as if the installation of TWRP just never happens despite that it looks like it is.

I get the blue line, but it finishes very fast, in like a second, no where near the two minutes Heimdall says it could take. And in the instructions it says I'm supposed to get a message on the pad saying it's completed, and that never happens. So I'm thinking the TWRP image is uploaded to the device but it's never flashed.

The device says:

ODIN MODE
PRODUCT NAME: SM-T800
CURRENT BINARY: Custom
SYSTEM STATUS: Custom
Secure Download : Enabled
KNOX WARRANTY VOID: 1 (0x0304)
RP SWREV: A1

No indication of it installing anything or being complete. If anyone has any idea why this might be happening I'd love to know. I'm following these instructions by the way https://wiki.lineageos.org/devices/chagallwifi/install
[Galaxy Tab S General] retiredtab:
This is the way I do it.

1. Boot into download mode.

2. heimdall flash --RECOVERY twrp-3.5.0_9-0-chagallwifi.img

3. As soon as you hit enter in step 2, start holding down the recovery mode keys. This is important as per document "NOTE: Be sure to reboot into recovery immediately after installing the custom recovery. If you don’t the stock ROM will overwrite the custom recovery with the stock recovery, and you’ll need to flash it again."

4. Keep holding those buttons until you see TWRP.
[Galaxy Tab S General] retiredtab:
It did flash successfully as per message above. If you don't boot into TWRP after this step, TWRP gets erased and you have to start all over again.
[Galaxy Tab S General] sergegalun:
Thanks. But I'm starting to think my issue is bigger than that as every time I do this it just boots back into the regular Android thing, and I've done it like 30 times now. I don't think Heimdall is flashing anything, it's just uploading the file then nothing. I was under the impression that it overwrites the TWRP as soon as I start it up gain, but I'm rebooting into recovery so fast now that that the screen is only black for a second, and if it overwrites it that fast then I don't know what else to do.

Do you get an indication on the Android screen that flashing has completed?

My instructions say this "NOTE: The device will continue to display Downloading... Do not turn off target!! even after the process is complete. When the status message in the top left of the devices’s display reports that the process is complete, you may proceed."

But I don't get any message in the top left corner saying it complete.
[Galaxy Tab S General] retiredtab:
Did you try the way I suggested?
[Galaxy Tab S General] retiredtab:
I just did it the way I wrote. No problems booting into TWRP 3.5.0.9. Here's the log.
