Just in case (maybe a silly question), are you sure you are in a Quadcore-R16 unit, CPU cortex A9 ... ?

I had the same problem, and resolved the way I explained to you. I disconnected the unit from the power (red and yellow cables). Put the canbus to groud. Then re-connect the power, and i got what you see in the attached image, the unit is in update mode, reading the usb media where I had the IQ Navi firmware. The process was successfull and I just mounted the unit in the car agin, that's why I can't share more pics, sorry.

Air condition

Hello,

I have a tonghai buy here:

fr.aliexpress.com/item/Quad-Core-1024-600-8-2Din-Car-DVD-For-VW-Volkswagen-GPS-Navigation-Radio-rds-Video/32629487867.html?detailNewVersion=&spm=2114.13010608.0.80.V6xdmB

wheels controls works good, but i have no information of my air conditionner.

I have an icon call aircondition but when i open it, it closed immediatly.

have you got an idea or another app?

thanks
[Android Head-Units] wigglitz:
I stayed up all night and did not sleep still trying and researching to to avail.

I do have the backups of my original partitions before I modified the unit, but I have no clue how to work with all of the .img files.

I was assuming using ADB. If so I think it might work. The unit boots at least enough to start connecting to bluetooth devices like I mentioned before.

Lol, I am like %85 sure that it is? I posted pictures from CPU-Z some pages back when I was asking if this was the right thread for my unit and confirmed that this was. I was still a little hesitant due to some conflicting information displayed in CPU-Z. It says R16, but then it says Cortex A7 Allwinner 23. Then again, I found other apps saying A9 when running on my unit (I have forgot which).

I attached the pictures I took before with the unit info. I would feel really dumb and confused if my unit was just slightly different enough to cause issues. Still, everything ran fine even multiple version of IQ Navi/RedMod up until this one incident :/

Edit: I don't want to continue cluttering the thread with more posts. If anyone would still be willing to try and help me resolve this issue, should probably talk through PM. If I ever do get it resolved I will post back on how I did. In case someone else ends up struggling with the same issue as I.So hopefully this will be my last or 2nd to last post regarding this issue

When you say you simply disconnected the red and yellow cables, may I ask from where? Out of all the wiring bundles that go with my unit, there is only 1 easy to disconnect/reconnect Molex connection. I had never kept this connected becuase it would keep my unit on 24/7 regardless of what state the car was in. This connection has a red and orange wire attached to the the cars female Quadlock connector. The opposite side has a plastic cylindrical tube (looks like a fuse inside) that splits the red cable. 1 goes to the ACC on the unit, the other to the Can Bus decoder. Lastly the orange wire seems to go to the ILL assignment on the unit.

If this is what you might be speaking of regarding the power wires you're using for this procedure, then yeah I have tried using this+ many various combos.

I really feel like I'm just missing 1 little step somewhere, and I am going to feel very dumb once (if) I finally realize it.

FAT32 USB/SD cards 16GB and lower

+more

~~ranting should be officially over now for me~~
[Android Head-Units] wigglitz:
Well that was fast.

I was finally able to get the unit to update off of the USB. It was actually the SW1 I needed to ground which allowed it to finally update.

I just ripped off one of the wires from my old unit's harness, shoved it in the unoccupied SW1 slot, grounded it and powered on. Initially it actually started to boot just as it had been, but I just hit the reset button and finally I saw the update screen. I've attached and labeled a picture showing the empty pin slots in hopes to help anyone identify if they are currently having a situation matching mine.

Thanks you so much [MENTION=7601685]cmaiquel[/MENTION] for helping me through this :)

Hello,

Glad I found this thread related to a unit I bought on ebay.

I just receive it, and this one is an upgrade running 1.8Ghz and Android 5.0.1.

I will try to root it with kingroot since I would like to install viper4android

I also found out that the unit does not mirror the screen to AV-OUT. I have 2 headrest monitor connected to the unit, and I wanted to mirror video being played from my USB to the monitors, but it will only mirror to AV OUT from a DVD or TV.

[Android Head-Units] wigglitz:
Just wondering if anyone might know what these extra files might be that I just received from the seller of my unit

Standard firmware update files:

92e82e86-1e25-11e5-bffa-000c29ba27c0

91973a18-1e25-11e5-b937-000c29ba27c0

Some uBOOT file I was told never to use:

90436790-1e25-11e5-9b35-000c29ba27c0

I keep reading on different sites that 1 or both of these has to do with the MCU:

648f8bba-ef09-11e4-8185-000c29ba27c0

bd07a5ee-fbb0-11e4-ae78-000c29ba27c0

Some DATA cleaning file that that I still don't even know what it exactly does or how to use it properly:

3072f462-8747-11e5-bf6c-000c29ba27c0

I am still looking in what the DATA cleaning file does. I am currently having an issue when installing some apps, and completely unable to install any Xposed modules due to my "Root" partition being %100 full. I tried moving apps from /system, but it did nothing.
[Android Head-Units] checksum123:
I have the same exact unit, but mine is for nissan murano. Were you able to root it?

I am trying to root mine so I can install viper4android.

I also cannot get my bluetooth ODB2 to connect to the unit.

[Android Head-Units] xda-ordinary:
Hi there,

Yes eventually rooted it with Kingroot. I don't know what actually made it work, I just kept trying and eventually it did it. I tried a bluetooth OBD, then a Wifi one, then a USB one. Only the USB has been rock-solid reliable. Connects every time instantly and stays connected. I got mine here https://australianrobotics.com.au/products/obdlink-sx-scan-tool

Love this unit, the only thing I haven't worked out is the "SD Card" memory, something like a few Gigs that it has onboard. Every time I move an app to SD Card, it vanishes after restart. Any advice from anyone on that would be great.

BTW (more for thread-readers benefit) Steering wheel key remap app doesn't seem to work at all but most of the keys I got out of the box were ok. In the Prado 150 Kakadu, the sound didn't work at first because of the AVBus controlled amplifier, but again, it just worked itself out once I got some apps in. One sure fire way of testing sound is to listen for the beep that it makes when you adjust the fader/balance in the stock app.

Cheers

How can I restore a TWRP backup? I cannot seem to make the unit boot into TWRP. I have a TH8681 and BT and the Volume and Tunning buttons stopped working. The TWRP backup is from before updating.

Thanks beforehand for any help!

I'm having an issue where I can't store any radio stations. Is there a specific way this needs to be handled?
[Android Head-Units] hgupta:
For whatever reason, it looks like it takes Kingroot several tries. Also, it needs an internet connection to work right.

---------- Post added at 02:40 PM ---------- Previous post was at 02:39 PM ----------

Are you on IQ Navi? The radio is much better using the IQ Navi firmware, and it is very easy to store stations. Just press and hold the preset button.

---------- Post added at 02:44 PM ---------- Previous post was at 02:40 PM ----------

I actually stated to like the stock music widget, with the IQ Navi updates. The Album art looks killer, and it is nice having the track name overlay on the screen.

But the widget is too small. I would like a big widget that shows the album art on the homescreen. Anyone know how I can increase the size of the widget? Or perhaps there is a way to get the song information from the app so that I can use external widgets (like Jack's Music Widget).
[Android Head-Units] hgupta:
Did you ever get the latest verions (0.1.293) from him? I am curious to hear about the differences.
[Android Head-Units] checksum123:
What version of Kingroot did you use? I used both the latest and 4.5.

When using 4.5, I tried 2X, the second time, it got stuck at 18% and I had to reboot the unit.

They are shipping me cable for the Steering Wheel control and my backup camera, I will see how it works.

I emailed them about the ODB2 bluetooth issue, so let's see what they come up with. I had an older version running 4.4.2 and I was able to connect my bluetooth ODB2 without any issue.

You are right about the 4.4 android, I did the same thing and I saw Android 4.4 popup, although they claim it is 5.0.1. But what matters is you can run most apps very smoothly.

Your unit says it does not have an SD card slot. How are you accessing the SD slot?

I also could not get the Anyconnect app to work, I am using a samsung note 4.
[Android Head-Units] hpric:
[MENTION=630626]hgupta[/MENTION], I am currently running stock firmware because I am too afraid to screw this thing up. This might not even be the same unit but it looks very similar. The system I'm running is

[Android Head-Units] hgupta:
I was scared too, but I am so glad I took the plunge. Just make sure you store your original firmware on a thumbdrive or cloud first. If things go bad, you can put the original firmware back on it using the same process.
[Android Head-Units] checksum123:
I was able to root mine with the latest version of kingroot after the second try. Even kingroot reports that it is android 4.4.2, they are advertising it as android 5.0.1, these lying bast***d.

I then installed viper4android, and to tell you the truth the stock equalizer sounds better than viper4android.

I am about to replace my 2 front speakers with the infinity kappa I just bought from amazon:

Question, i have stored the radio stations.

But when i start the car and the unit is startend it always start with : FM 87.50 and not an present nr.

How can i fix this ??
[Android Head-Units] hgupta:
Sounds like your car isn't providing constant power. Double check your connections.
[Android Head-Units] hpric:
Is your clock also resetting? if so then you may have your constant and ACC reversed
[Android Head-Units] kloenie:
The radio stations are remembered, but at first boot the radio always go to fm 87.50

then i need to press the radio presets that are remembered.. but i want another fm then fm 87.50 as start of the unit.

now i always need to press a radio preset.

as you can see on the picture..

this is the first thing we get when the unit starts.

second question.

The misses wants there steering wheel controls back.

I have an iso connector for this radio, but maybee i need soem extra wire's in it.

Can someone direct me in the correct wires ?

the old radio :
[Android Head-Units] hgupta:
That means that your radio is losing power when the car is off. It needs a little bit of power to remember which station it was last on. Check your connections, especially constant power.

---------- Post added at 01:38 PM ---------- Previous post was at 01:37 PM ----------

Old radio shoudln't matter. Your unit should have come with an adapter to interpret the steering wheel controls. Go back to your reseller and ask him about it.
[Android Head-Units] kloenie:
i thought, maybe someone can see on the wiring how i can connect to.

i know there is a key1 and key2 on the new radio.

and i know i need to connect some cables on it to work..
[Android Head-Units] Hisma:
nobody is going to know how to wire in your steering wheel controls unless you provide wiring diagrams. If you don't have wiring diagrams for your car, buy a service manual on ebay.
[Android Head-Units] hgupta:
I think this requires more knowledge about your car and stereo. If your seller can't help you, then I would recommend going to a professional installer.
[Android Head-Units] Hisma:
Not true. If you can acquire the wiring diagrams for your car, you can do it yourself no problem.

The only catch is that your SWC are resistive controls, and not canbus-only. If canbus-only, key1/key2 won't work. You won't know any of this unless you see the wiring diagrams.
[Android Head-Units] Remiguel:
Try to mesure the resistance between 13 and 16. If the resistance is changing while pressing buttons on your steering wheel, the control should be resistive and should work with key 1 or key 2. Korean cars used to use resistive controls ;)

If your test is positive connect key 1 or key 2 to pin 16 and 13 to ground.
[Android Head-Units] Hisma:
good find! I did not see the photo the OP posted showing the pin-outs of the wires. Yes you can see if resistance changes when pressing buttons and measuring across those pins. Wiring diagrams will say for sure what you have, but if you have difficulty acquiring those diagrams, what was stated above will also work.
[Android Head-Units] kloenie:
[MENTION=7188777]Remiguel[/MENTION], Awesome it works.

I was searching what Remocon Front Signal coulde be. en just before i got the anwser you got it right.

I did a quick mesurement with the to pins 13 and 16.

I connected in the connector Nr 16 to Key 1

And connected connector Nr 13 to Ground

Started the unit and started to configure the buttons.

AND IT WORKSSSSS

easy peasy, i tought it would be a big thing to get it to work, but just 2 connectors and ready.

Thanxs all for the help.. the misses is happy, so i am happy ;)
[Android Head-Units] Remiguel:
Glad that works :good:. Lot of harness are ready plug and play, but with so many brand and model in the market, it is not that easy to get the right one.
[Android Head-Units] kloenie:
True, but with normal thinking and some help we come far.

Needed to pit 2 extra connections in the original connector and connect to the key1 and ground.

[Android Head-Units] wigglitz:
Has anyone previously owned a MTCB/Malaysk ROM 4.4.4 unit before? I loved how the F-Cam was able to switch between front and reverse camera's with the single button on the screen. I am on RedMod 294 currently. Although there more settings for changing/turning on setting a front camera, along with 2-3 extra apps. None of the combinations I have tried will allow me to get signal from my reverse camera or my front USB camera. The "Recording" app is the only app that will initiate and allow me to view my front cam. I am sure if I used the video composite cables to connect another front cam, that this would solve that issue. But I still have found no way to view my reverse camera without actually putting it into reverse. I have constant power to the camera. It worked fine on my MTCB unit. I would like to be able to see and adjust guide lines without putting in reverse and pulling the e-brake. I also used to have some Tasker or some other setup, where if someone was riding my bumper I could just hit an assign widget/shortcut on the desktop to quickly snap a picture of their plates. Just in case...because I can be paranoid.

Hello all, I would like to install IQ Navi on my unit.

I've downloaded 0.1.24 version, however I'm not sure if this is the newest and I do not know how to message Mobi 97 on the 4PDA forums because of the language barrier.

Apps moved to SD Card disappear after cold boot

Hey all, I know this has come up a few times before. Just checking to see if anyone has solved this issue. My unit has no physical SD Card slot but it does report two distinct storage areas in the settings (see attached image). It also allows you to move apps to SD, in the apps settings as normal. This appears to work, but after a cold boot, any apps moved to SD Card seem to vanish. It's annoying because my main storage area is only 1.5GB, whereas the other area is 12GB. can only install a handful of apps before running out of space. Is this only an issue with KIngroot-ed units? Just looking for a pattern.

so am i the only one that can't get my phone to connect via BT automatically? Anyone have any idea of things I can try? I had a previous joying HU that connected automatically. It's pretty annoying.

Also, I find that when setting the standby time to 1 hour after shutdown, when I turn the unit back on and it's wakes from standby, it seems apparent that the unit kept playing the audio even when in standby. It does not pick up where it left off, since it kept playing when the car was off. Anyone else experience this issue?

Really hope we get some dev support on these soon.

---------- Post added at 01:46 PM ---------- Previous post was at 01:44 PM ----------

why do you need an updated play store? just curious. I find that updating google apps on these HUs causes more problems than it solves.
[Android Head-Units] deekgozzinyea:
I probably don't in truth

My main reason for wanting the updated play store app was too see if the login issue was related to the app version or the head unit. Other than play store I get great connectivity and can log into Google services through Chrome, which makes me suspect the app. I also run uber and lyft and uber isn't receiving GPS data even though my GPS app gets it just fine
[Android Head-Units] imableeblob:
Try making Uber your default GPS app. You might lose your GPS system but I believe that setting dictates what apps have access to the GPS utilities. Similar to how Bluetooth is restricted to the default app.
[Android Head-Units] Hisma:
Connected aftermarket amp & sub today. the sub out issue is not a problem on my HU. I connected my sub to sub out and it controls fine in poweramp. I can adjust "sub" in the "zone" settings and I hear the sub level change with it.

The only issue I am having is a very high frequency "white noise" that I hear with my pre-outs connected. I did not hear this with the amp outs. It is low enough to where I only hear it w/ no music & at idle. If I'm moving road noise drowns it out. I think this has to do w/ the outputs being unshielded. SQ is very good now that I added an external amp & sub to drive my aftermarket speakers.
[Android Head-Units] sciallo:
Could you please tell me what version of the unit you have (buttons, knobs 2 din or vehicle specific...) And what system and especially MCU version as shown in the "about device" ? I would love to be able to use my sub out... I'm going for a MCU update to fix that
[Android Head-Units] Hisma:
Here you go. Sorry for the horrible glare. Does my software line up with yours?

Mine is a car specific model ('14 mazda 6)

[Android Head-Units] deekgozzinyea:
didn't work

I tried that, but it didn't work. I also installed Google maps and Waze and tried setting them as the default GPS app since they are the two apps Uber feeds from. That didntbwork either. I suspect the play issue and GPS passing are limitations of my head unit's MCU and/or software. Problem is I have an ehotch 8081 which isn't referenced on xda much and the seller can't get me an updated MCU file or image. The MCU designator in settings is also just the version number and date so I can't figure out which updated MCU file from the MCU thread would work. I am thinking the GS update for the 3188 quad core would work but I am not willing to risk bricking my unit to find out lol.
