Good morning everyone.

I bought my ownice c500 and I have a question for you.

After installing launcher (car launcher form android market) I do not see standard applications (radio, music, etc).

I searched the internet for a solution to this problem. On the web site of a forum is like a solution and answer the question:

Q: The third-party launcher does not see the standard application (Radio, Music, etc.). How to solve a problem?

A: You need to install the program fromthis message.

But the message link does not work :(

You know how to solve this problem?

BOB!!! can you tell us some details about the internal components and which model this Ownice radio is?

The backside is so thin it could fit in every car...

I have one question. If I want to install a front parking camera, how can I see it automatically on the HU when I turn the camera on? Like happens with rear parking camera.

Does the HU shows the video signal when it receives signal from AUX VIDEO input?

Or do I need to buy a RCA switch and connect both to REAR CAMERA input?

Thanks

Has anyone yet managed to get the right skip-button to work with poweramp, to skip to next song? On an older Android-HU there was a special RK3188-headunit-service to get this working and I wonder if there's anything similar for the C500?
[Android Head-Units] yurtesen:
[MENTION=2628563]Argentum_90[/MENTION] the radio gets the rear gear switched info from canbus or from backup wire in the harness. (Depends on if your car has canbus or not). So I believe it can't switch between cameras when you are parking.

[MENTION=6246726]Flemischguy[/MENTION] I believe it is c500+ http://www.ownice.com/Pro_Head Unit_450.html But I think it won't fit to many cars due to larger screen size.

Radio is stupidly big, but I think the reason is the DVD models. :( I would have liked c500 to half it's depth, 90% of it is empty space inside anyway...

Did any of you try

persist.sys.shutdown.mode=hibernate

in build.prop ? Because it makes booting only few seconds on my mtk tablet... It could be awesome if it works on c500

Hi, I would like to buy a Android head audio and saw this topic. This Ownice C500 is the best option that I have? Does it have a good software support?
[Android Head-Units] Argentum_90:
[MENTION=3394679]yurtesen[/MENTION] yes, my car detects Reverse through Canbus. But I have a separated button to start and shut off the front camera manually. What I want to know is if I can get the signal automatically in the screen when I start the front camera.

The rear one works perfectly.

Oh god, I could finally root my HU, thanks to this video.

In the wiki is not written /system/bin before /forfan guoboneedav -i, so I couldn't root my device. Maybe obvious for pros, but uncomprenhensible for noobs in the Terminal.

If you rooted the unit, did you try to set the hibernation in the build.prop ?

persist.sys.shutdown.mode=hibernate
[Android Head-Units] Argentum_90:
[MENTION=3394679]yurtesen[/MENTION] do you get faster boot?

How can I activate this hibernation? Is there any how-to out there?
[Android Head-Units] yurtesen:
[MENTION=2628563]Argentum_90[/MENTION] unfortunately I didn't yet. It was so much more pleasurable to try these when the unit was on my desk with a keyboard and mouse. But in my MTK tablet, it reduces boot time to about 3 second. It breaks the boot logo on my tablet, but I can live with that.

You just open /system/build.prop and add this to bottom

persist.sys.shutdown.mode=hibernate

You can use FX File Explorer's internal editor with FX Root Add-on to edit files as root. I think it would be the best option. There is a build.prop editor from jrummy apps but I read some reviews that it sometimes does empty the file etc. (Not so safe as fx editor)

This setting should be safe but if you do something wrong, you may have boot problems. So, do it on your own risk. Doing stuff as root is usually not very safe :)

Did anybody get to extract the new radio app from C500 quad and octa that has RDS station names? Is simply to extract from one and paste in our old HU, or something more complicated than that?
[Android Head-Units] yurtesen:
[MENTION=2628563]Argentum_90[/MENTION] Your friend probably did something wrong or changed some other settings which caused it. Because I couldn't find any post about any device being bricked because of that option. So, who is your friend and did he post this online? Word of mouth, so unreliable :)

But if it does something, one can simply recover by re-flashing the rom easily. The rom would overwrite the file with the original.

I ordered a remote/keyboard/airmouse to keep in the card. I will try the option when I have the keyboard...
[Android Head-Units] Argentum_90:
How can you enter in recovery mode in the Ownice C500? I thought it was not possible.

I think you can edit the build.prop with the touch keyboard. Not very long text [MENTION=3394679]yurtesen[/MENTION]
[Android Head-Units] yurtesen:
[MENTION=2628563]Argentum_90[/MENTION] I will try it next time when I am in the car. I tried on another mtk phone and it didn't do anything. It is just do uncomfortable to use the onscreen keyboard.

You don't need to enter recovery. Because you can install ROM without a graphical recovery by following normal ROM update procedure.
[Android Head-Units] Argentum_90:
Does an usual rom update serves to recover a bricked HU?

[MENTION=8521383]alukart[/MENTION] , exactly what unit do you have? So far root worked for all of us. I don't know if ownice changed anything in newest units but you seem to be entering right commands :(

---------- Post added at 09:41 AM ---------- Previous post was at 09:36 AM ----------

@fredin if the unit was for your car model, I would expect there would be place for the connector. Otherwise you need to cut it and connect to something which turns on to 12V when backing up. In ownice connector it should be going to 5th pin from bottom right side if I remember correctly.

---------- Post added at 09:52 AM ---------- Previous post was at 09:41 AM ----------

@Argentum_90 I didn't try it, but it should. If you flash wrong ROM to your phone, you can recover by flashing fresh one. It will work as long as unit allow you to flash new ROM. Ownice doesn't have graphical recovery, but it does it's job and install ROMs, as long as it is not broken, you should be able to install fresh ROM.

[Android Head-Units] yurtesen:
[MENTION=6457386]fredin[/MENTION] NO, the "back" wire is simply for detecting when you put your gear to reverse. If your car doesn't have canbus etc., you would connect it to reverse switch on gearbox or reverse light positive end.

Camera is connected to a completely different harness! It is at the block of white connectors between antennas. If you read the text on the unit, you can see that rear camera is mentioned clearly.
[Android Head-Units] fredin:
I connect the camera just to the rca connector, no need to connect the back with canbus car

Hi, I try to connect a battery to the 8-core Ownice C500. Which points should I connect. I tried GND 15 and 12v on 16 and later 14.

Please help.
[Android Head-Units] velocity4:
If you look at the diagram in the C500 FAQ, if you want to power it up outside the car, connect +12V to both red and yellow wires and black to ground. Or, you can connect yellow to a battery and connect the red to a switch and then the battery, that way you can switch the unit on and off without having to disconnect direct battery power all the time.

It worked. Thanks a lot.

Hello everyone

On my octacore I lost the buttons on the left.

I can activate 3/5 (with the software menu > 1) but each reboot the functions have disappeared.

How do I program buttons?

Does a reset with a metal tip remit the device of orgine or I risk a brick?

Thanks foy your help

[MENTION=5589241]SwissGalaxy[/MENTION] how did you lose the button functionality at first place? AFAIK reset hole only power cycles the device.

---------- Post added at 02:40 AM ---------- Previous post was at 02:35 AM ----------

A while back, my screen was showing ghosts etc. on my quad core. I contacted the seller on AliExpress and they sent me a new screen. Changing it requires soldering iron and basic skills on removing solder and resoldering (patience also helps). I was surprised that they just sent me the screen without even asking if I can install it. Anyway, it works great now! Thanks Ownice!

---------- Post added at 02:43 AM ---------- Previous post was at 02:40 AM ----------

@argentum_90 the hibernation setting doesn't do anything. I also realized the quick boot is selected in the "accessibility" settings but it doesn't seem to work. On my mtk tablet, this greatly speeds up the boot process. I don't know why it doesn't work and I couldn't find any information online. I imagine it may require some specific partition or file for hibernation but who knows where that should be :(
[Android Head-Units] Argentum_90:
Ok. Thanks for sharing your information.

[Android Head-Units] twirly:
I have had my quad core for a few months now and what has bugged me most is the resets.

Now I read from some other users here that this is due to some bug when the network drops.

Did a longer drive a couple of weeks ago and indeed every time the network dropped the unit reset.

That should be fairly easy to fix in an update.

On my unit saving radio channels does not work properly as it does not save them after reboots.

Anyone else experiences this?

Except for those 2 things I'm quite happy with the unit even if boot time is a bit long but it does not bother me that much.

I should however add that I have rooted and done the viper mod as sound was horrible.

Pin assignment for DVB-T2

Hello everybody,

Somebody can inform the pin assignment for DVB-T2 connector of C500 ?

What is the pin number for R-in, G-in, B-in, UART-RX, UART-TZ, Csync, GND ?

This connector is having 10 pins at rear of head unit.

The ownice DVB-T2 product is not quite stable picture, I want to change with other DVB-T2 receiver from Asuka TV.
[Android Head-Units] yurtesen:
[MENTION=5589241]SwissGalaxy[/MENTION] I recommend contacting to seller. I think you may as well have a hardware problem. You shouldn't lose buttons just by removing power as it shouldn't change any settings. It may be that unit does not sense buttons and disable them. But, I had problem with my screen and seller sent me new, it requires soldering to detach buttons from screen assembly. It is a job to be done carefully, because screen is surrounded with many thin flat cables. So, beware :) by the way, from which software menu you change button settings exactly?
[Android Head-Units] SwissGalaxy:
This is not a hardware problem because I can program them with another function. The problem is that I have to do this every time I start and the buttons 1 and 2 do not work.

Here is a short video:

https://www.youtube.com/watch?v=lRk-IIbH1Lw
[Android Head-Units] yurtesen:
[MENTION=5589241]SwissGalaxy[/MENTION] You are probably right. I thought you had hardware buttons.

In either case, it would be good to contact seller. One thing to check is if your radio is always getting power to yellow wire. One other person had a problem that radio would lose saved stations when turned off because it couldn't shut down properly. Do you have such symptom? I can turn off car and remove key and put it back within 1sec and my radio stays on. If power was cut off, it would have rebooted.

What I would also try is to exit button settings with back button then open recent apps and swipe the app away. Sometimes completely turning off an app forces it to save things.

If that doesn't work, I would set buttons then go to hidden menu with 1260 and change something small and let unit reboot by itself (it asks to reboot to save and apply settings).

Let us know if you find a solution.

[Android Head-Units] SwissGalaxy:
@ yurtesen

The yellow power supply is correct, I do not lose the stations and the device does not cut when I cut the key.

By changing LCM type for another one (there are 4 differents modes), I can find all the buttons except "turn off the screen" but the programming disappears with each reboot ...

Can these original parameters (ROM) be re-imported?

[MENTION=5589241]SwissGalaxy[/MENTION] at this point, your guess is probably as good as mine. I didn't mess with LCM settings myself. It sets display connection type so I thought it may cause empty screen which would be difficult to fix. Did you ask help from seller? What does the seller recommend?

I have just installed my touch only universal c500. When I power it on there's this white noise sound in my speakers. Of course you can't hear it if there's something playing (radio, MP3 or whatever). Did anyone have this problem or know how to fix it? The other problem is that I can't power it up unless my key is in on position. Originally with oem radio I could power it up without turning on the key. Is my wiring wrong or is there any setting for it?

Hi guys, from wiki about the name of radio stations:

"RDS does not show station names. However "Bob" from Winlink mentioned that there will be a firmware upgrade to fix it."

This issue has been resolved in octa-core version of the unit. A firmware update for quad core units is expected.

I'm using Ownice C500 OL-8992F that is an octa with the latest firmware (Feb. 24, 2017 preinstalled) but the problem persist. What is wrong with my unit ?

Hello, I have built the device in, in the car. I have now two problems, and I think they have to do something with each other:

1. When bluetooth with my phone gets disconnected or my phone send a notification sound through the bluetooth channel, apps that were open, minimize and I return to home. This is very annoying, sometimes I have maps or music player on the screen and it dissapears without any notice.

2. Secondly the device settings gets a reset out of no where, the volume and equalizer changes to default and other settings under the section "Car Infotainment" also resets to default, such as display brightness. And it always happends when the apps gets minimized or the phone sends notification. But not always.

Hope someone can help me out with this annoying problem.

My theory about the vw bluetooth unit is invalid. Since the morning I have no sound from the navigation unit.

Is it a hardware fault or wiring fault? I have two tweeters, front L and R speakers, back L and R speakers and amplifier with subwoofer.

When I replace the unit with my oem original unit (from volkswagen) then I have sound.

[Android Head-Units] JeDaj:
[MENTION=3394679]yurtesen[/MENTION] - true, I hear it only when everything else if off. I can live with it. [MENTION=1302347]yobikap[/MENTION] - my OEM radio didn't have Bluetooth. It was standard radio/cd/mp3.

Now this unit starts to drive me crazy. I had it installed for couple of days. I rode with it for 300km or more. Every now and than it restarts all the apps in the background. For example: I'm driving with radio and sygic. Radio in background and sygic on screen. After some time the sound from radio stops, unit looks like quit all the apps (shows main screen) than it starts the radio on top. I have to go back to main screen and turn on sygic again. It happens randomly. Sometimes it happens after 20-30 minutes of driving and sometimes like 3 times in a minute. First I thought it could have something with network that some people were noticing, but I don't have simcard inserted. No WiFi. Just two apps running (radio and sygic). Also I have noticed that it happens when I had only radio playing or only music player. Looks like the apps doesn't matter. It resets randomly.

Any thoughts? Bad wiring? Faulty unit? Short maybe? For myself I will take out the unit and rewire it again. Maybe it will help. If anyone else experience similar things, let me know.
[Android Head-Units] Kurt Lund:
Yes, get rid of the unit. Mine did the same thing and I ended up by buying a MTCD unit instead and the C500 is now in the dumpster. With MTCD units at least you have some sort of support from people like Malaysk. Bob from Winlink is nothing but a Bull Sh...er who does nothing but making false promises.
