I'm using rear cam but not with CAN bus (it means that I use rear lights 12v to inform the C500 that I'm in reverse mode). With the C500 the camera is not always shown on the screen ! Sometimes it's OK, sometimes it's black for 5-6 seconds then the image appears and sometimes it black forever ... Additionally to that the image it too bright (when it's not all black of course ;))

With the C200 it was working all the time with the same camera installation in the same vehicle and the image had correct brightness...

i saw on a pumpkin forum (even if it's not the same brand)that sometimes it needs additionnal relay plus a constant 12v

power.

the 12v coming from the backup light seems to be insuficient.

try to power the cam with 12v from the dash, to check this eventuality?

Yes, you can get good signal if you are next to the tower also. That does not mean that you have optimal antenna location. I look at your photo and you have 2 bars in 2G ! unless your garage is several meters underground, this shouldnt happen. -> https://xdaforums.com/showpost.php?p=72304046&postcount=1148

The benchmark is you stand outside the car with your phone and check the signal level(not the bars) with signal meter app, then compare it with the radio. I get better signal in radio than in my phone. Same is true for the GPS signal. Radio has much better accuracy and signal levels. It is quite important for GPS actually, because the radio does not have built-in compass.

It is a matter of physics, you will at least loose significant amount of GPS signal if your receiver is in your dash, because of the roof. Maybe in a perfect sunny day, in the middle of a field, it makes no difference. But when you drive in city with tall buildings and bad weather, you may have problems.

Problem with screen proportions and certain apps

I wonder if you had a problem like mine with Spotify, that you can't log in because third option to log in with email and password is outside screen? As shown on first picture.

Also, Viber suffers from something similar - incoming call cannot be answered, because button to do so is outside screen area (second picture).

Red rings shows approximate positions of missing buttons. Does anyone have any idea how to solve it?
[Android Head-Units] yurtesen:
[MENTION=1589025]Sorensonn[/MENTION] When you run spotify in your phone, are you able to switch to landscape mode at the same screen? It is entirely possible that spotify only made portrait mode for this page and that is the problem. Normally software can lock the device to portrait mode but since c500 is locked to landscape only some programs may have this problem. Another example is Here We Go Maps which does not have settings menu in landscape mode. This may be same for Viber, since they think you wont use your phone in landscape mode when answering a call.
[Android Head-Units] Sorensonn:
Yeah, I checked it and on the phone Spotify login screen is forcing portrait mode, so it's mostly their fault. I think I'll let them know about this issue. As to solve it I think one of the apps that force and lock screen mode (portrait/landscape) should solve this problem for Spotify.

Anyway, forcing menu button to permanently show up on C500's screen would be nice, and moving navigation bar to bottom edge, like in tablet, too.

Rear Camera

anyone of you guys has already installed and connected a rear camera to Ownice c500? which one did you bought? is the camera view working automatically by putting the reverse gear?
[Android Head-Units] yurtesen:
[MENTION=1589025]Sorensonn[/MENTION] Already tried, once you force c500 to portrait mode, the bottom half of the screen disappears. I even tried to mirror the screen to my phone.

I think one solution may be changing the display dpi, or use a keyboard with tab button to go to hidden menu item. But neither are practical.

[MENTION=8284614]ziko0609[/MENTION] yes, camera works automatically if you have canbus or connect the reverse wire to reverse light bulb power. It doesn't matter which camera you would have. All composite cameras I saw work similarly.
[Android Head-Units] Sorensonn:
@yurtesen - that's right, I noticed that the bottom half of the screen is black when forced vertical, but it's still working so I could hit that login button eventually after several blind tries and completed login process. What's curious, keyboard is shown on this empty half of the screen just right.

Changing DPI and several other things would be nice. I'm really missing xposed...

@ziko0609 I bought a camera integrated into reg frame, like this one:

https://www.aliexpress.com/item/Wat...ar-Number-Rear-View-RearView/32764471947.html

Image isn't perfect and it certainly doesn't have 170 degrees view angle, but it's okay. Camera kicks in automatically after switching to reverse, but radio must be completely booted.

BTW I was able to set radio stations one time and they were saved and restored properly after reboot, but right now every time I set them an reboot radio - they are gone and I need to search for them again. What am I doing wrong? Right now my unit is connected so it's losing power after switching off ignition, but I intend to change that soon. Wonder if this will hep.

And when will they finally add radio station names? Without it rds is incomplete.
[Android Head-Units] velocity4:
You have Quad core right? I think in this thread it's a good idead to state which one you have as Quad works differently to Octa:)

On the Octacore, camera works as soon as the unit is on. and RDS radio station names are working.

I was able to get this cam to work as designed with recording to onboard msd card using apk called usb cam. Trick was to find sidebar menu that allows external usb card recording. However.this apk conflicts with cardvr. So it will not work as I hoped. I now believe that a standalone full funtion dvr cam without screen but with msd onboard, wired to 12 v acc will be best bet. This means you have to remove msd card to view on computer or place into flash drive and view on c500. So here is the next cam I will try:

720P HD Smallest Mini Car DVR Camera Video Recorder Small Vehicle Auto Dash Cam Camcorder with G-Sensor Wide Lens

Look up on AliExpress.

There is also possibility to put this cam RCA feed cable on switch with backup cam for v500 viewing. Finally, there is a wifi version of this type of cam available but at double the cost but that would be best solution and would not conflict with front cam recording or playback.

Hi guys,

did anyone get Apple Music to work?

I cannot reach the login, because of the landscape view.

Thanks!
[Android Head-Units] yurtesen:
[MENTION=8297740]theWrongest[/MENTION] I believe sorennson managed to use a program to switch to portrait and could click on login for spotify. You will not see where the login is because bottom half of the screen disappears. But you can use the login button if you can find where you are. If you can keep yourself logged in, this would be a solution. Otherwise you must complain to the producer of the application. Because it is their fault that they don't support landscape mode.

I think it is not so black and white. If you buy quad core today, you will have station names also. It is unknown if new quad core units have the camera problem fixed or not.
[Android Head-Units] velocity4:
Been following posts regularly and I haven't seen a single post about an Ownice Quad core with working RDS on the radio. Do you have a reference?

[MENTION=8256263]velocity4[/MENTION] Yes there was a user here who ordered from gearbest a quad core and confirmed that the RDS works. His username was Arnizzle

Anyway, just by dumb luck I got a response from Bob about the firmware. He says:

[MENTION=2628563]Argentum_90[/MENTION] I believe that require installing google apps manually. I think a service is missing. I will try it at some point myself. I think I saw something about parking lines in one of the menus actually. I can't remember where now. I am not sure if those parking lines are useful?
[Android Head-Units] Argentum_90:
I thought the same than you until I could see that I can't see the bumper of my car from the camera, so I have no refferences.

It would be wonferful if Ownice use dynamic lines reading the steering wheel angle from canbus, which is not so difficult.

[MENTION=2628563]Argentum_90[/MENTION] I think you need the OK Google Hotword Enrollment package.

https://github.com/opengapps/opengapps/wiki/Package-Comparison

I think ownice has the pico package, the Google app is also missing in the system. If you can install hotword enrollment, you could perhaps use OK Google from anywhere. If you are rooted you can try the opengapps app from store to install nano version or perhaps try to put the apk to system apps location manually. Let us know if you can solve this issue.

I guess LCD is dead. After messaging Ownice I opened it up, checked the cables, but it didn't help :( Ownice is eager to send me a new LCD, but I have to cover the shipping costs.

Maybe someone here had the same issue? Or am I the first one?
[Android Head-Units] yurtesen:
Are you sure you didnt select something to invert the screen colors? I know from my phone that I changed screen DPI and the boot logo gets screwed also, some setting may cause this problem from the boot. If you are not rooted, you should try factory reset and if you were doing some root stuff, I would recommend putting original firmware again then do a full reset before deciding the issue is screen for sure the problem (it is probably a fault in lcd but why not be 100% sure?)
[Android Head-Units] Gleniu:
Unfortunately, I did all the following things before contacting Ownice. You can see on the video that the issue persist also in booting animation - if it was something software related, it would happen only after full boot. Moreover, it went back to quite normal for a short time, then back to faulty. It is LCD for 99%, unfortunately...

Internet Tethering via Bluetooth

I just installed my Ownice C500 Octa Core and I'm very happy with it.

Does anyone know how to get this to work?
[Android Head-Units] Mammûûth:

[Android Head-Units] Petce:
I have tethered via wifi no problem and it is currently how I am going about giving the unit an internet connection.

Does anyone have a solution for this?
[Android Head-Units] gormiza:
Adjustment of bluetooth. Auto-connect
[Android Head-Units] Petce:
I dont exactly understand how I would go about doing that.
[Android Head-Units] lottumeb:
In your phone itself go to settings menu, networks.

There is option more... or Thetering and mobile hotspot.

Open that, in there is option Bluetooth-thethering, turn this on.

Then you go in HU to settings Bluetooth and turn on autoconnect.

If anyone is interested, i have a complete manual for download.

[Android Head-Units] yurtesen:
[MENTION=4844419]lottumeb[/MENTION] if I am not mistaken, there is an option to turn off grid lines for parking camera in the hidden menu or in a settings menu. I can't remember where exactly, but I remember seeing it.
[Android Head-Units] lottumeb:
Yes you are right, found it yesterday.

Think it was in engineermode, but i would have to check again.

I searched so many things yesterday :D

Correction, it's not hidden, it's in Video menu.
[Android Head-Units] yurtesen:
[MENTION=8280052]Petce[/MENTION] the problem is that you would need to connect to internet sharing profile. I am not sure if you can set it from your phone once c500 is connected. Maybe if you can access Bluetooth settings in c500 using an app, you can add this option. Otherwise c500 will not use internet sharing.
[Android Head-Units] Argentum_90:
Can you tell me exactly where to find the option of parking lines? I have looked in 1260 menu but I can't find anything.
[Android Head-Units] Sorensonn:
I wonder if I have the C500 connected as it should be. Standby time for now is not working for me, but I didn't yet tried the solution from Ownice. Can you guys switch on the unit via the button on it or something and use it normally when the ignition is switched off? I can't and I wonder if it should be like this.

By the way, I found out how to solve the problem of radio loosing frequencies of memorized stations after switching it off:

1 - set the stations as you like it

2 - turn off the unit via the button (on my unit it's the round volume knob in the upper left corner - if press it for several seconds it puts the unit to sleep, I can switch it on by pressing the button again)

3 - turn off ignition

Then, when I switch the ignition again and the unit boots up, after opening radio app it will have all the stations and will play the last station I left it on.

PS I wonder why Titanium Backup cannot see system apps like radio, are they hidden somehow?
[Android Head-Units] yurtesen:
[MENTION=2628563]Argentum_90[/MENTION] try the engineering menu, it is explained in the wiki.

[Android Head-Units] Sorensonn:
@yurtesen My signal is more often above 40 and sometimes reaches 50, I'll take a photo later. What is the position of your gps receiver? Mine is in the lower left corner of the front window.
[Android Head-Units] lottumeb:
In normal settings in Video.

[ATTACH]4165294._xfImport[/ATTACH]

Looks like you have better reception than me, and i'm also in northeren Europe, Netherlands.

Antenna is on left side just under the roof.

I think i'ts very dependend on your location and how many satelites are in the area at that moment.

---------- Post added at 17:34 ---------- Previous post was at 17:23 ----------

It's normal that you can't switch on the HU when ignition is off.

That means you have at least the ignition cable connected (= red ACC 12V)

The other one should be Yellow Battery 12V, which will keep your settings when you turn radio off.

Off course you do have to connect them in the right place as well.

Maybe switching them can cause problems.

If, for any reason, you would accedently connect ACC 12V twice (so no 12v battery), you would always loose all settings because HU gets no voltage at all when ignition is off.

That's how a traditional radio works.

No idea if HU's store settings in flash memory/eprom or something, and keep all settings when powered off.

My HU does not loose radio channels.

I store them simply by holding the channel button for 3 sec.

Probably Titanium Backup can only see system apps when the HU is rooted.

Is yours rooted?
[Android Head-Units] Sorensonn:
Guess I'll just have to pull my unit off and see what cables (and how) they connected. As for loosing settings I can see that time is always off and gets corrected once the internet connection is on, so probably HU have no battery at all. And I could store stations by pressing onscreen buton for 3 sec, but after reset they were gone. Only after above procedure they got saved for good.

My unit is rooted, titanium backup still can't see system apps, probably for the same reasons other launchers can't. Wonder if installing these stubs from wiki for other launchers will solve this.
[Android Head-Units] halloj:
Why should it have a battery? It's suppose to be connected to a car battery continuously.
[Android Head-Units] yurtesen:
[MENTION=1589025]Sorensonn[/MENTION] 50 is amazing. We had clouds when I took that photo. Must try to see at open sky one day. My receiver is on the roof. Attached photo... I tried to document my installation, it was not so easy :) http://evren-yurtesen.blogspot.fi/2017/05/golf-mk4-variant-gpsgsmfm-triplex.html

[MENTION=4844419]lottumeb[/MENTION] I think the geographic location should not have effect on number of satellites or the signal strength as long as you are at about sea level and you are not surrounded by mountains etc. If you are on high altitude or mountains block your sky view, then it could have drastic effects. If you look at the orbits of the satellites, they are very uniform and they have a fixed altitude.
[Android Head-Units] yurtesen:
[MENTION=4844419]lottumeb[/MENTION] HU totally switches off. The battery power has no meaning once you turn it off. It stores all data in storage.

[MENTION=1008438]halloj[/MENTION] the problem is that the HU forgets the time. For example normally you would have internal battery even in your laptop which has its own external battery and it is connected to power.

However, there shouldn't be a battery in HU because it would be dangerous. It should have a low power clock which can work internally to keep time with power from the vehicle battery. But I put a sim card and it takes time from gsm network (you don't need internet for that). So I didn't even notice this small problem.

---------- Post added at 10:45 PM ---------- Previous post was at 10:37 PM ----------

@sorensonn I think the apps in the radio are not native Android apps. That's why navigation sounds dont work while radio is on.
[Android Head-Units] halloj:
Honestly, you don't know what you're talking about. If your HU forgets time, it's not hooked up properly. You have two power cables. One connected to your battery, which will supply current 24/7 as long as your battery is good to go(yellow cable). The red cable is the control cable normally connected to your ACC. It will tell the HU to go from sleep mode to active mode and vice versa. For correcting the time you have three choices. 1. Manually. 2. Thru your network connection. 3. GPS. Hence, it will remember the time, but maybe not down to atom clock level.
[Android Head-Units] yurtesen:
[MENTION=1008438]halloj[/MENTION] you may have a point. I don't actually know if my HU forgets time. As I mentioned I have a sim card and time is always correct. I relied on the information that [MENTION=1589025]Sorensonn[/MENTION] gave. Maybe he has wrong connections, maybe thats why his radio can't remember stations also.
[Android Head-Units] Sorensonn:
Yes, every time HU boots up I can see that time shown is 08:00 and it stays like that for 5-10 seconds until it gets corrected by the gsm network, so I thought it would be good to have a small battery for real time clock support. I definitely have to check the connection and see if the battery power is connected at all. Maybe radio stations are written to flash on power down, but if my unit just loses power after ignition switched off it couldn't do that. On the other hand, it was losing them even without powering off, after reset (quick reboot app). May be a software bug.
[Android Head-Units] Argentum_90:
Thanks [MENTION=4844419]lottumeb[/MENTION]. I got the parking lines!

However, I can't access to engineering mode. I write the code in the Phone app, and when I finish typing it, dissapears automatically and does nothing.
[Android Head-Units] Kurt Lund:
Mine does the exact same and it is not connected to network or GPS time - I have both options switched off. Even if I stand in a parking garage where there is no GPS signal and I don't have a SIM card or any other source of Internet connection, then it still does the same thing. And my radio can't be connected incorrectly because it is a VW type model where there is only the plug from the car that plugs directly into the plug in the radio. On another note my clock positioned in the status bar does not show exactly the same time as the clock in the right side widget - very strange. Further I often experience that the clock in the status bar freezes. Is there a way to remove that clock?

Regards

Kurt Lund
[Android Head-Units] Sorensonn:
@Kurt Lund You mean that you still have wrong time after bootup, even when connected 100% correctly with factory plug? Does the time stay wrong? Or it gets corrected after some time, or only after getting signal from gsm/gps?

As for removing the clock from the status bar that would be possible with xposed installed, and a module like gravity box mm or similar.
