"DVR" or "Record" function

Has anybody been able to use "DVR" or "Record" function using the factory software?If yes,what type of camera,RCA or USB or what model?
[Android Head-Units] adsawin:
DVR works with Camera from Zhoon from Aliexpress on DVR Connection.

Hi Rui,

try to set the device back to factory.

Maybe this will work.

Or you can try to flash 2.9.5 again.
[Android Head-Units] m00n61:
The best firmware now is RedMod from 4pda. It is based on 2.9.5, has root and viper4android included. looks nice also. The version you can find here is 1.4 and is probably the latest stable build. On 4pda there is a 1.5 beta available if you feel brave :)

Also check the radio mod, also from 4pda. definitely worth installing.
[Android Head-Units] areax99x:
Help...

what do you mean by " Or you can try to flash 2.9.5 again", i never did flash. give me some instructions please.

Thanks for the reply

How I download this RED MOd,i been there and click on the link but it doesn't download.

hello, I flashed the firmware "blue mod 0.9.4" taken from the Russian site works all right. Still I do not understand how to operate recording cam dvr.
[Android Head-Units] Macje:
Friend, dvr is simple, just looking the connector that says "video in, or camera in" and that you associate to the default program in your radio, the menu tells you what will be the source of the video and gives you some options, now you select the input with signal and ready ...

* you have to use a camera with RCA terminal, USB is not supported by all models

Amigo, el dvr es simple, solo busca el conector que dice "video in o camera in" y a ese lo asocias en el programa por defecto de tu radio, en el menu te dice cual sera el origen del video y te da algunas opciones, seleccionas la entrada que te de señal y listo...

tienes que usar una cámara con jump RCA, usb no es soportado por todos los modelos

un abrazo

-about my case, i update the radio and everything works again the dvd, music, radio (with memory), backup camera, front camera, GPS, and further recognizes me 4 sources of memory (sdcard, USB1, USB2, USB3) all work.

but .... the bluetooth works perfect just the first restart of the radio, if I turn off the radio no longer work in the next on of the radio, and must reset back to work again... to know that this problem is?, need help

-the digital TV even let me see no image, a message blocking, as I watch digital TV again? any idea?

sobre mi caso, actualice la radio y funciona todo nuevamente tanto el dvd, music, radio (con memorias), cámara de retroceso, gps, y adicionalmente me reconoce 4 fuentes de memoria (sdcard, usb1, usb2, usb3) todos funcionan. pero.... el bluetooth funciona perfecto solo el primer reinicio de la radio, si apagola radio y la prendo denuevo ya no funciona, y debo resetear nuevamente para que funcione... saben a que se debe ese problema?

-la TV digital aun no me deja ver imagen, aparece un mensaje de bloqueo, como puedo volver a ver TV digital?

Hello, I need help, I had the system version 2.6.40, upgrade directly to version 2.7.11, as I did not like, I went back down to 2.7.9, but now I want then updated again, I press to update the system, the system starts, there is a text update start and update end. seems as if the upgrade does not detect the sd. I did a factory reset but still can not update. I saw that the factory reset delete all less the steering wheel buttons.
[Android Head-Units] wanxu:
I don't know what's happening to you. I would install last firmware: https://yadi.sk/d/286TKo4ndmQSH. That applies to [MENTION=2323243]juninyo[/MENTION] also. Or try to change anything in Settings/extra.

No te sé decir qué pasa. Yo le actualizaría al último firmware (2.9.5 para sistemas de 800x600): https://yadi.sk/d/286TKo4ndmQSH. Entra en el menú que te dije y prueba configurando allí. (Settings-extra)
[Android Head-Units] juninyo:
hi, I can not flash anything, to get a message to reboot "start update end update". the system does not detect the update files, the sd is formatted and uncompressed files in your root.
[Android Head-Units] wanxu:
That's because you have one device attached. Try this: uncompress the firmware update in the root of the device memory and try to update WITHOUT anything attached (no usb, no sd card). So, don't update from the SD but from the internal memory.
[Android Head-Units] juninyo:
hi, thanks for the help. I've done what you say, I disconnected the external sd, connected internal sd, the Pen of WiFi and the rear camera, I've put the update on the device memory and internal sd, I can not upgrade, same message "update start update end ". The device starts, I look at the update files to copy in the device memory and are not, they have been deleted. It seems that the system does not let you change.
[Android Head-Units] wanxu:
What do you mean internal sd? I mean put the firm in the device memory. Just there. The 2 firm files.
[Android Head-Units] juninyo:
Explorer file using is this: device is the memory of device, sdcard is internal memory (the memory can not be removed) and extsd1 that is the card in the slot, I put the files on device and sdcard
[Android Head-Units] juninyo:
I copy it to the root, second photo
[Android Head-Units] wanxu:
No, put it in /mnt/storage/sdcard. Not in the absolute root, sorry!
[Android Head-Units] dipcore:

[Android Head-Units] juninyo:
nothing happens, the strange thing is that when I do a factory reset will not lose the root, either lose steering whel configuration. The MCU if I can upgrade, is there any way to leave everything to 0 ?, the factory reset does not help me.
[Android Head-Units] Macje:
My friends, I followed your advice and install this version, almost everything works normally, I appreciate your help, it helped me a lot.

-only me is to solve the issue bluetooth update works only when but just for once, to reset the radio again stops working and will not work until it is updated again ... be a problem with the hardware?

at the beginning of this issue I saw a user changed the hardware bluetooth, I recommend something ?.

about the TV, I still did not fix the you can not see the screen plugging a yellow sign that says "warning ... watching video while driving is prohibited," it appears to me on TV and when I put videos ... as I can avoid them ?, unfortunately not so good to me ...

It serves me any help.

a hug.

-------------------------------------------------------------------

-mis amigos, seguí tu consejo e instale esa version, funciona casi todo normalmente, te agradezco tu ayuda, me sirvió mucho.

-solo me queda poder solucionar el tema del bluetooth que solo cuando actualizo funciona pero solo por una sola vez, al reiniciar la radio nuevamente deja de funcionar y no funciona hasta que se actualice nuevamente... sera algún problema con el hardware?

al principio de este tema vi que un usuario cambiaba el hardware del bluetooth, me recomendarías algo parecido?.

respecto de la TV, aun no logro solucionar el que no se puede ver por que tapa la pantalla un cartel amarillo que dice "warning... watching video while driving is prohibited" esto me aparece en la TV y cuando pongo Vídeos... como puedo evitarlos?, lamentablemente así no me sirve de nada...

cualquier ayuda me sirve.

un abrazo.
[Android Head-Units] wanxu:
[MENTION=6899180]Macje[/MENTION], there's an option under Advanced Settings called something like "Watch video while driving". Maybe you have to switch it to avoid that message. I don't know what happens with your bluetooth, it's really strange. Maybe is the phone. I would remove the BT pair connection from both the phone and the device.

Espero que lo entiendas en inglés.

[MENTION=2323243]juninyo[/MENTION] I'm sorry, I don't know. It's really strange... Try another firmware. I'm pretty sure is something simple, file placement or something like that. Did you disconnect sdcard1? You told you put the firm in the device memory and internal sdcard. Do it just in one place.
[Android Head-Units] juninyo:
if you've done all that, I tried other files, I tried with files that resets the unit, but the device did not flash anything, always the same message, even when the sd don't have update files, to reset the device, sometimes get the message "update start update end". I put a picture of my device, my device changes the order of the buttons, if it is the same as yours, can you tell me which MCU has, thanks
[Android Head-Units] Macje:
friend I think the same thing happened with my radio, it is a simple step ... try to get as wanxu said, all device memory, sdcard, pendrive and wifi or anything connected to a port of the radio ... then you put it on a flash drive less than 2g, only system files choose the link that wanxu then you put the flash drive in the USB port that says..., then reset by brute force, you press the reset button + power button, and then forces the radio to searching files ... I should read you the system files in pendrive without problem .. wait a few minutes and ready.

---------------------

amigo creo que me paso lo mismo con la radio, es un simple paso... trata de sacar tal como dijo waxun, todo dispositivo de memoria, la sdcard, pendrive y wifi o todo lo conectado a algún puerto de la radio... luego pones en un pendrive de menos de 2g, solo los archivos de sistema escoja los link que dejo wuxun, luego pones ese pendrive en el puerto USB que dice sólo eso... USB, luego resetear por fuerza bruta, presionas el botón reset + power luego sueltas reset y después power... asi fuerzas la radio a buscar archivos de sistema... debería leerte los sin problema.. esperas unos minutos y listo.

Lo entiendo perfectamente no te preocupes...

Solucione lo del video y TV (Muchas gracias por la ayuda), lo del bluetooth no lo logro solucionar, no es problema de pair connection, ya que en todos los celulares es igual, en la radio simplemente se pone en blanco todas las configuraciones del bluetooth cuando se reinicia la radio...

Un detalle aparte... la perilla del volumen sólo baja el volumen.... saben a que se debe ese problema...? Desde siempre a estado así. ...

----------------'-

I understand perfectly not worry ;) ...

Solve the video and TV (Many thanks for the help), the bluetooth I fail to solve, it's no problem to pair connection, since in all cell equals, radio is simply blanks all settings of the bluetooth when the radio restart ...

A detail apart ... the volume knob down the volume .... just know that this problem should be ...? Since always been so. ...
[Android Head-Units] wanxu:
[MENTION=2323243]juninyo[/MENTION], that is the message when you are trying to change firmware.

Update Start

[tries to locate the update file and does it]

Update end

So my guess is it's not finding the update files or they are not correct or it is finding them in more than one place. How do you update? I always go to Settings -> General Settings -> System Update, but I know you can do it via button combination. If it's not that, then try another workaround: remove all update files from internal memory and try to do it from USB or external SD card root. Of course, FAT32 devices.

[MENTION=6899180]Macje[/MENTION], I don't know about the bluetooth. It always worked for me. I once tried to root the unit and the BT failed then, but I suppose you did anything, right? Have you updated the MCU? Maybe it's that. About the volume, in Settings -> General Settings -> Advanced settings the volume button is called "Knob". I remember there are some options for knobs there. For instance if your car has one or two, or if you want to turn right or left... something like that. Maybe you have to change some option there.
[Android Head-Units] roystervi:
[MENTION=834020]m00n61[/MENTION] do you have a link to 1.4 and 1.5

1/ is it already rooted so I don't have to root it after I install

2/ do you or anyone has screen shots of the install and how 1.4 looks

3/ does these has a red warning?
[Android Head-Units] Macje:
a silly question .... how i update the MCU? where those files are placed? because when I put upgrade MCU does not show me anything ....
[Android Head-Units] roystervi:
does 2.9.5 have a red warning, is it rooted already and do you have any pic after install or can you post some pic of your home screen and the radio screen thanks
[Android Head-Units] juninyo:
the message is "update start update end" nothing, no string of numbers and letters in the middle. I leave it as impossible, I think there is something that prevents update. someone who has the same device as mine, can you tell me the MCU installed ?, thanks to all
[Android Head-Units] RAJIJI:
Please help!! OUKU ? will not go past the start up screen

Bought this unbranded unit direct from China (alibaba) last year and unit 'packed up'after a month or so. (seller was not helpful in the least and basically ignored me)

Looking at the various threads on the forum, it seems my unit is the OUKU, however when purchased the website called it' ''ETRONS'''

here's what I do know, again from seller's listing:

AN21, PURE 3G WI-FI, ANDROID 4.2, CPU FREESCALE 1.MX535D , CORTEX A9 DUAL CORE, IGHZ ,RAM DDR3, 1G RAM, INAND MEMORY 8G, WITH DVD-T

Unit came with the requested Australia maps and has a touch screen

I have in my own amateur way tried to reset and also pressed the reset/volume buttons that then goes to ''start update followed by end update'' and then nothing !!

upon start, I do get the green android logo followed by the the next screen that has ANDROID that flashes across... Nothing after this at all (although the reversing camera works)

Please help as cannot buy another unit.

Thanks in anticipation

Raj
[Android Head-Units] macca017:
Why don't you try the latest Red Mod firmware.

You will find a link to the firmware on a few posts prior to this one.

Just unzip it onto a sd card, put the card into your unit, start up and go to settings, go to "general" and select update and wait until it's finished.

It may help if you have a firmware problem.
[Android Head-Units] roystervi:
[MENTION=5797001]macca017[/MENTION] or anyone: have you install the latest Red Mod firmware, if you do can you or anyone upload some screen shots for us? also is the Red Mod firmware rooted like the rest firmware.

thanks in advance
[Android Head-Units] macca017:
Yes it's rooted.

Looks the same as the old Red Mod.
[Android Head-Units] roystervi:
Sorry I have been away from the forum for a while, l went back as far as the 600's to try catch it on post but I still haven't seen any screen shots of the red mod install. I will like to see some screen shots because I know in the pass, software updates are only someone doing a custom mod of the players. So like to see if the whole software skin is change in red mod. I have 2.8.8 install. Can anyone take a cell phone screen shot of their 2.9.5 or red mod install. It would be greatly appreciated.

Thanks in advance.
[Android Head-Units] roystervi:
Sine everyone keep saying red mod but not posting any pic I went ahead and update to to redmod 1.6 here are some pic. As I thought nothing new in the update as to a diff skin, look and feel. its the same the old setup.

If anyone have 2.9.5 install can you upload some skin shots.

here is my screen shots of redmod 1.6.
[Android Head-Units] darkhaziel:
Hi, I have the same head unit, but I have no more information than you have. :(

Would you know how to export your MCU?

IMPORTANT: Do not change the MCU through the model choose menu -> extra settings !!

I've changed and I lights do not work volume level: '(

Nobody knows anything about this head unit?

And how to export the MCU image?:crying::crying:
[Android Head-Units] oddbehreif:
Only took two before installing RedMod (only saw your post after, sorry!). This is the default homescreen and radio app.
[Android Head-Units] roystervi:
is this a screen shot of 2.9.5?
[Android Head-Units] smubob:
Whats the difference between one and three buttons? :)
[Android Head-Units] oddbehreif:
Roystervi, I'm 90% sure. I don't remember the exact version but it definitely is 2.9x.

Smubob, three-button version has home, back and app switcher in the status bar while the one-button version only has the app switcher button. :)

How to install Red Mod and roll back to stock rom

Hi Guys,

I have been following this post before i buy the device and due to this forum and your efforts i finally got the device from Ali Express.

It is for Peugeot 508.

I just have a quick question, if i installed the Red Mod 1.6 Rom and want to roll back to stock Rom, how to do this? Is there a way to create a backup for the Stock Rom and be able to flash the stock Rom again?

Also I have no SD Card slot, so how could I flash Red Mod?

Thank you for your help.

maybe you have enabled "sleep model" in the settings "Extra settings -> Model choose"
[Android Head-Units] gpmg762:
There is a warning of no ignition and no power off if set to 2 VW models on mine but how do you set it back to generic again?
[Android Head-Units] donaldta:
I guess it wouldn't hurt to try Key 2 but in [MENTION=1915855]KID52[/MENTION]'s picture indicates "For steering wheel control key 2 (only connect when the car has two positive signal wires)". To me, that its analogous in having two separate test leads, much like having two separate multimeters. So, you'd probably get the same result either way.

You're right about not needing ground because the SWC adapter should already be grounded through the AN 21-U's "#9 GND black wire".

Are you using a T-tap or Posi-Tap connector? or did you cut the B31 wire altogether? It may already be too late, but I would suggest

not

cutting the wire until you get a schematic or can confirm that the wire is

only

going to the SWC buttons. I would hate for you to cut that wire only to have the airbag deploy which would cost you hundreds to replace.

Maybe check to see if there is a dip switch or software control to change the SWC adapter to switch the analog leads to test between resistance or voltage.

Without knowning the schematics, here's how I would imagine it:

Car's ECU (+5VDC) ---> B31 wire ---> SWC buttons ---> Resistors ---> Ground

In which case, if you tap into the line, you'd get voltage references because your car's ECU is measuring the impedance of the current by using 5V of pressure. If the Key 1 and Key 2 wires do not respond in the app to program it then it probably means that the SWC is only measuring resistance. Maybe ask your seller, June, if there is a way for the AN 21-U's SWC to measure voltage as opposed to resistance. Otherwise, you might have to cut into wire and splice the Key1 wire towards the steering wheel column (not the ECU). But again, be very careful because doing the wrong thing might end up deploying the airbag.

Otherwise, you might consider using a third-party device to handle the SWC controls for you.

Yup, in the picture attached uses two open resistance loops with a common ground. Let me identify the layout. The black wire (G22 #20) would be connected to AN 21-U's Key 1 and the orange wire (G22 #18) to Key2. This is because the black wire is responsible for Volume Up, Volume Down, and Mute while the orange wire is responsible for Seek Next, Seek Previous, and Mode. The purple wire (G22 #19) is the common ground between both circuits and would need to be connected to the car's (or radio) ground

In other words, in this situation if the black or orange wires were disconnected then only half of the buttons in the SWC will work. But, if you disconnect the purple wire then none of the them will work.
[Android Head-Units] KID52:
It says that for system update too. I think what it means is don't turn the power off (to either constant 12v, or ignition), or you may bugger the unit up.
[Android Head-Units] avgaz:
This warning indicates that the option is enabled during disconnect power radio
[Android Head-Units] omarko:
I saw that setting but I don't know what it was for as it only offered two VW models and I am not sure if that means Volkswagen or something else. What are these two "models" anyway? Do we know what they do ?

I dont think this option has anything to do with ignition or constant power. I think what the warning means is : "Do not turn off power or turn ignition on/off during the model update. "

What do you guys think ?
[Android Head-Units] sorin129:
I did not cut the B31 wire from the steering wheel, all i did was solder Key 1 from the radio to it. I did not think I needed to cut the wire since it the multimiter was reading fine the voltages from the buttons when I tested. So ether this unit does not measure voltages or I need to cut the B31 wire and connected to the Key 1 on the steering wheel side. I will also contact the seller about the swc in the unit but do you think is a possibility it does not work because i did not cut the wire from the steering wheel and i just spliced in to it Key 1?

EDIT: I also contacted the seller and this is what she send me:

"Please kindly download the SWC setting from the link below and setup it step by step.

http://www.cnkick.com/litb/Downfile/421645_Steering_wheel_control_learning.xls

Please let us know how is the result after your setting, if problem still exist could you please take some pictures of the DVD screen to show us? "

It's a little confusing because here they are saying to connect Key 1 or Key 2 to ground. ????
[Android Head-Units] KID52:
Yes, that's what I said, don't disconnect the power during update/changes or it will bugger up your unit :P

I think maybe the models could have something to do with the CANBUS functionality or similar? Only speculation though. I can ask Peter Chan to see if he knows.
[Android Head-Units] omarko:
That would be great if you wouldn't mind asking. cheers
