Hi there,

I installed my ownice c500 yesterday, the fact is i have a rear camera too.

I needed to get another RCA cable (10m) to get to the front of my VW T5 (long version).

So i do not have the red power cable on this one, i wonder how to connect the "back cable" on another source of information?

Because for now i have no camera switch when i get on rear, while camera is working (checked via Video input directly, works when pulling rear).

Thank you :)

Anyone know how I can lower the start up volume? In the 1260 menu the lowest value I can set is 10, I cant set it any lower for some reason and 10 is too loud in my opinion.

DVR Camera Troubles

Hello,

I have the Ownice C500 7002F (quad core). I am not able to get the DVR camera to work. The first time I tried it the camera (plugged into "DVR/USB") was working but there was a message that said the TF card was missing. I did see an image from the camera.

I put a micro-SD card in the slot on the C500 next to the SIM card. Note: I later learned that there is a slot in the actual camera.

After rebooting, I ran the DVR software ("Traffic Guard") again and now it no longer shows the camera image, but a picture of a road with a round menu. I can rotate the round menu, but the only button that does anything is the center exit button.

After learning that the camera has a slot, I moved the micro-SD card to the camera slot and get the same results.

So next I removed the micro-SD card altogether and still have the same results (round menu as described above).

Can anyone provide help for this?

Also, is there a firmware upgrade for this head unit? I purchased it in July of 2017.

rebooting

Hello, all,

I just installed the ownice c500 head unit, all functions went well, but every time the head unit is turned on for the first time after about 1 minute, the head unit reboots. After rebooting, all normal, no more rebooting.

Can this issue be fixed?

Ownice C500+ | WiFi issues

Hi everyone.

I have 5 HU installed in VW Golfs.

Every HU have issues with WiFi: after 5 minutes of running it start to work really bad, ping is rising up to 500-750ms.

Is anyone else had such issues?

Is it possible to connect HU to the router via USB connection or ethernet? Please, share your experience or any ideas. I'm desperate to find solution to this issue.

Hi! The screen of my C500 started to display strange colors. I'm not sure but this is maybe related to a little hard braking as I've noticed this just after. I disassembled it, reconnected all internal connectors, checked continuity on each lane of the video cable and looked for unsoldered or damaged components but I found nothing. Does anybody know this problem or have an idea to fix it?

Try this:

Go into "Settings" then "Storrage" , see if you the unit can find the USB stick first.

If the unit can see the stick , then i mean (im not 100% sure) you can choose the usb stick to be a part of the Android storrage .

I think mine ended called it "Udisk01"

Try this and get back, if its not working ill check my setup and return to you again (im not at my car now :) )
[Android Head-Units] MugenSi:
In order to use the USB stick as Internal storage its telling me that it needs to be securely formatted to the unit which will erase all data on it and render it un-usable with any other device. So I can do that but if I do will my Windows 10 desk top machine recognise it and allow me to put all the music back on to it again?
[Android Head-Units] kekec777:

What filesystem is on this usb stick? if its FAT32 and the device recognizes the stick I see no reason Poweramp shouldn't be able to read its folders.

If its NTFS there's your problem:)
[Android Head-Units] yurtesen:
It looks like your screen is damaged somehow. I had the same problem (I think I even have a picture from it some 10-20 pages back in this thread) and my seller sent me new screen. I don't think it is due to braking. It happened to me after I disconnected the device then reconnect. Maybe some production fault could cause it.

If you get the screen, the problem for you would be that it needs desoldering/soldering (at least they just sent me the LCD/Digitizer only). It is not difficult and you can use a normal soldering iron and solder wick but I wouldn't recommend if you have no experience in soldering. It is still more difficult than soldering wires in place, also you have to be more careful obviously.

Is it possible to turn off the car info app ? I mean for example opening doors pop up this car info app over everything,

Thanks
[Android Head-Units] BuffMcBigHuge:
I have the same problem with my C200. The only solution I have found was to plug a USB mouse to the back of the unit, and use the mouse and voice control while driving.

:rolleyes:

You can try the following:

1) Update SDUPDATE & MCU,

2) Full factory reset,

3) Play with touch panel settings in factory settings,

4) Physically removing the touch screen, checking connections,

5) Aquire ghost.img and reflash to ghost partition (using Root & Terminal).

su
dd if=/mnt/external_1_sd/ghost.img of=/dev/block/platform/emmc/by-name/ghost
reboot

You will have to contact Ownice or scour the internet to find the correct ghost.img.

I have a problem with reverse camera perhaps. I connected the wire for the "back" to the radio. Waited to to fully boot. When I put the reverse gear, it reduces radio volume but doesn't open any video view (camera not connected yet). I assumed it should give black screen. It detects reverse because the volume is lowered with reverse volume suppression. This is an old 4-core unit. Can anybody tell if this is normal? Is it because I don't have the camera yet?

Update: nevermind, I realized I had camera detect turned off from the hidden menu and that caused no camera function apparently. Now it is fine.

[Android Head-Units] yurtesen:
[MENTION=6246726]Flemischguy[/MENTION] do you know which competitor has a better device with 4G/LTE and also same depth or smaller than ownice? C500 barely fits into my car. If it is few mm deeper, it would not slide in completely inside the 2DIN slot..

[MENTION=9139867]Master1201[/MENTION] I think you may be able to remove it from 1260 hidden menu OR you can maybe go to app settings and disable application if possible? I think I disabled mine from 1260 so it does not even appear in installed programs if I am not mistaken.

Random reboots workaround

I just want to share with you my workaround for random reboots caused by weak GSM signal.

I bought a Huawei E8372 wingle to my car. Unfortunately, simply taking the SIM card out of the C500 didn't help, as well as disabling mobile data - the device still connects to network for emergency calls purposes.

So, I enabled airplane mode, which turns GSM radio off completely. Then, I manually reenabled WIFI and bluetooth. No more reboots :)

Moreover, now I have a far more reliable internet connection - the Huawei wingle just do far better in weak signal conditions.

I know that it's not a real fix, but I was eager to pay some bucks to solve the issue. Now the only drawback is that I have airplane mode and no SIM icons in status bar.

EDIT: I removed airplane mode and no SIM icons in status bar using system UI tuner. To enable it, just pull down quick settings menu and tap and hold onto settings icon (cog). After few second release the finger and head to the bottom of settings - there will be a new entry, system UI tuner, you can disable icons from there.

EDIT2: Ehh... Two reboots today... So it seems that the device reboots itself when there is no internet connection, no matter if it is through mobile data or WIFI. I guess that the only fix then is to throw C500 to garbage, where it belongs. It is my last Ownice device, for sure.

Finaly i have managed to root my ownice and instal V4A, god, it completely changed the sound. I stoped using the deezer eq, no need now, bluetooth sound very good, the only thing is the radio sound, reception is good but sound only reacts to the standard eq, rusbish...

is there any way to disable auto power on when the unit receive power from the car? and force shutdown when the engine still on?

my car doesn't support "standby" because it always power off all electricity when the key "pulled", so I'd like to going "old school" by turn it on/off manually when the engine still running to preserve battery

thanks
[Android Head-Units] velocity4:
Do it the simple way. Just install a switch and connect it from the unit ground or tie the yellow and red together. I prefer to switch to ground rather than to +:)
[Android Head-Units] ils:
thanks, but I was hoping to find "soft"er way

rather than the "hard" one :P

I'm afraid the forced shutdown makes the system more prone to failure

yup, mine's always powered on when receiving electricity (key Acc On). it doesn't stay off.

[Android Head-Units] Sorensonn:
Hi guys, I have 4 core version of C500. I wonder if you have similar problems with the unit:

- side buttons - no backlight, no matter what settings I try, they remain dark. Makes the unit hard to use at night.

- unit turns off completely after switching off ignition, no standby for 30 mins/1 hour. Switching the car on immediately after switching it off begins the long, cold boot. Wires seems to be okay, in-unit settings messing doesn't help.

- the biggest one for me: when the car stays in the hot sun for several hours and the inside gets very hot, the unit can't see sim-card. Reinserting it doesn't help. It needs to cool down to see it again.

Did you experience it as well?

Hello everyone, since yesterday the sim card slot doesn't work anymore, it doesn't detect the sim card, yet it worked very well so far.. I have the symbol no sim card insert, I have try with a new sim and also try to reset the device. I tried to contact the customer service on Aliexpress and they tell me that the sim card support must be dead and offer me to buy a new one for $ 15, but I do not know if it's difficult to change it ? Has anyone ever done it? I imagine that we must dismount the whole box? Do we have to weld? Thank you for your answer
[Android Head-Units] rickardoat:
Hi.

The side buttons doesn't turn on because these are disabled by default, there is a cable called ILL that needs to be connected to the lights of the car, this in order to stays off in the day and turn on in the night, this cable also manages the dimming of the screen.

For the unit turns off with the key, there are two cables for that you need to check, the yellow cable needs to be connected directly to the positive pole of the battery and the red cable needs to be connected to the ACC main switch of the keys.

And for the sim card, i suppose that there is a cold soldering in the sim card board, if you have some soldering skills you can disassembly your unit and re-solder the pins of the sim card board.

I hope this helps...

---------- Post added at 11:38 AM ---------- Previous post was at 11:31 AM ----------

Yes, you have to weld, the sim card board is welded to the screen board

You can see the sim board in the right bottom corner of the image.

I couldn't found any launcher like that, you can install Car Launcher from GPlay and modify it by yourself in order to get some similar to that launcher.

---------- Post added at 12:21 PM ---------- Previous post was at 11:53 AM ----------

yes, you have to remove the top cover and the display assembly, i remember that are only 5 screws, 1 for the top cover and 4 for the display assembly, removing these screws you will have access to the sim card board.

If the re-soldering doesn't work it is possible that the sim board is damaged internally.

[Android Head-Units] dartveiga:
Yes. Me too. Only use Spotify, Google Play Music and Waze. Sometimes (3 days per week) it reboots on its own. I think it is related to Internet connection.
[Android Head-Units] ils:
maybe i'll try not to use Waze for awhile

see if that particular app is the problem

though it's already working for a few months now without problem

edit:

definitely not Waze.. i think this is temperature issue.. my HU's CPU temp around 65C - 75C

also the CPU Clock didn't drop down at all.. it stays at 1248 MHz all the time... anyone can confirm if this is normal/by design?

i'm using CPU Monitor to see the stats : https://play.google.com/store/apps/details?id=com.glgjing.stark&hl=en

2nd edit:

i remove the HU's top case, installed a CPU Casing fan, the CPU temp dropped to ~40C

hopefully it won't random reboot again. just make sure you use the "ACC" as power source, otherwise the fan will run 24x7 (unless you mod the +12V using a manual switch)

2) Then un-zip the donwload file to get the two files" 3562.upd" and "3562.bin "

3) Then copy the two file " 3562.upd" and "3562.bin " to one new usb disc root (can not change the files name), then connected with our device usb port.

4) How to update: Keep touching the screen，then turn on the device power ACC, then release your finger when the screen turn on. (The

upgrade process takes about 10 minutes)
