This is interesting as I have always been confused as to what is and is not a C500+. For instance my model is an octacore, but it is not a C500+:

http://www.ownice.com/Pro_Head Unit for 2din universal_449.html

It seems to me the only ones they label + are the ones with bigger screens.

Yeah seems so, it wasnt obvious at the time I posted this but it kinda is now.

Just got my new C500 octa core too can't wait to install it in my old mercedes.

i have connected a Behringer UCA202 USB DAC , then i have (as described in the FAQ)

1: Root your unit

2: Replace the /system/etc/audio_policy.conf

But i have no sound output ?

do i have to add the nexus 7 files to get it work ??

any idea what is going wrong ?
[Android Head-Units] Zewak:
I have connect Behringer UCA202 USB DAC like its say in FAQ. Its work fine. Sound really great. But i have ext amp and good loudspeakers.
[Android Head-Units] ALkes_13:

Hi Zewak - could you please tell us more details on your config? In particular I'm interesting if you have sound output from let's say Radio or Youtube via USB connection only (between C500 and UCA202). So, could you please answer on the following questions:

1 - did you connect C500 line outputs to RCA inputs on UCA202? Or it is connected to C500 via USB only?

2 - Which sound sources can you listen to via UCA202 and USB connection? Can you listen to the let's say YouTube, when C500 connected to UCA202 via USB only (and no RCA connections between C500 and UCA202)?

3 - In case of 'Yes" for my second question - is it a stereo signal or only mono?
[Android Head-Units] Zewak:
Hi.

I connect USB, RCA input and RCA output. So, i can listen all sounds from C500 play, Radio, youtube, GPS warnings and ets. But when i want listen sound from UCA202 i use USB Audio Player Pro app. This player is great and can work without RCA input connection. Signal from UCA202 and USB Audio Player Pro app is stereo.
[Android Head-Units] ALkes_13:
Thank you for the answer.

Just to clarify - in other words, if I get you right, all sources except USB Audio Player can NOT be played through USB connection - they are still DACed inside C500 and going through C500 line output (RCA) -> UCA202 line input (RCA) -> UCA202 output (RCA) -> External Amplifier.

So, sound quality from USB Audio Player should be dramatically better than from other sources (even for the same media, let's say an mp3 file, played by USB Audio Player and some other mp3 player installed on C500), correct?

Does anybody know if it's possible to do the same (digital-analog conversion inside UCA202, not inside C500) for all other sound sources? In particular I'm interesting in streaming radio applications. Thanks!
[Android Head-Units] Zewak:
yes, everything correct

sound is really better. c500 have very poor sound and after installing UCA202 i cant listen any music from c500 , only from UCA202. (But u need unferstand, that its my own opinion.)

u can listen streaming radio from USB Audio Player

DAC wiring - only usb possible ?

Hi,

If you have to use RCA output from the DAC, then it's mandatory to have an external ampli to connect to it ?

There is no way to process the sound by the dac and then make it going out by the internal c500 ampli (and speaker wire to it ) ?

Thanks

Hello,

I want to order the C500 from Aliexpress.

1)Does anybody know if the C500 works well with WAZE and 4G sim ? I've heard problems that WAZE only works with WIFI hotspot or something like that...

What about the navigation sound? does it work good?

2) when I buy from Aliexpress- how can I tell them about the jumper fix for the external mic issue?

thanks
[Android Head-Units] ngochoangimsat:
1. Camera delay is a hardware issue!

2. Now, you can add some functions for back buttons only when you root and install combo "xposed framwork + xposed additions"

3. In the future, may be some one will write some app such as MTC-Keys, MtcdTools, SpotifyKeys, button remaper, .... for this unit. But now these app only working on MTC (MTCB, MTCD) devices

front camera and external microphone issues

I have Ownice C500 4 core installed in my Toyota Land Cruiser.

1. Although the rear camera works fine, trying to install a front camera and connect it to the AVIN, the camera got broken (already happend to two cameras!) did anyone ecounter this issue? is there special consideration in connecting the camera to the AVIN?

2. Additional issue is with the exteranl microphone. Connecting it and placing the jumper seems OK, however sometimes the external microphone works and sometimes it doesn't. while the external microphone does not work and the internal microphone is disabled by the jumper, I can not use the phone. Is there a known fix?

3. Also connecting a DOK to the USB with music, works after the connection, however after turning the egine off for more than 1 hour causing the unit to reboot, the USB is not recognized and I need to disconnect it and reconnect it again for the unit to identify it. Is there a fix for that too?
[Android Head-Units] Armony:
22-Sep-2017

1. I managed to connect the front camera to Aux (AVIN) and it is working fine.

2. The problem with the external microphone was the mail connector was mono and the feamale connector of the C500 is streo. Thus the connection is not stable. I dismantle the feamale connector and connect only the red wire (disconnecting the white wire) and it works fine.

Hi,

I have a doubt. How can I play the songs by usb when I am playing Spotify music? I have bought a UCA202 and c500. Neither arrived yet, But i am still looking for the sound solutions.
[Android Head-Units] aluver:
Thank you for your grateful post.

I am not an owner of c500 yet, but I am very interesting about its capabilities about usb audio. So I have some questions:

1. I have compared the original audio_policy.conf of c500 with your version for usb-dac and noticed you deleted strings about 64 gain steps of volume adjusting. Does it mean c500 now has only default 15 steps of volume instead of 64? Does it have that 64 steps in fact by default?

2 Why did you set sampling_rates 48000 for usb_device section? Is it because uca202 can't play stereo and you use UAPP for music playing? For those who gonna use sa9023 or else I think sampling_rates 44100 would be a better choice.

3. What if try to make a minimum changes to original audio_policy.conf? I hope its only usb_device section must be changed. What do you think?

4. Didnt you or may be somebody try hi-res usb-dacs with c500? I am interested to use it on 24 bit depth. Now I have RK3066 MTCB HU and it cant stream to usb 24 bit sound without artifacts (clicks&pops) because of bad DWC otg usb driver.

Sound to the speakers stopped

Hey guys,

I have Ownice C500 in my LandCruiser for more than half a year and after resolving minor issues it worked fine. However starting few weeks ago, the head unit still works with full functionality but no sound is ouput to the speakers. After some time (minutes), suddently sound starts and works fine as long as the unit is on. After few weeks, where the silent time become longer, I thought it might be an electrolitic capcitor in the head unit. I opened the head unit and replaced the large 3300uF 25V electrolitic capacitor, but this problem continues. Now the silent time is even longer. Anybody has an idea for a solution?
[Android Head-Units] ninet:
Regards:

My team is an ownice c500 octacore, installed in a Ford Focus c-max.

I do not know if the lighting problem you describe is the same as the one I have.

My equipment, turn on the lighting of the buttons when I turn on the lighting of the car. But, the illumination of the screen does not always go down. Occasionally, it darkens and quickly brightens up to darken again, thus continuously. But this only happens on some occasions, it is not every day.

I would appreciate it if you could indicate the change in the wiring, which could solve this problem, if it is the same fault it gives you.

Thank you

Is there anyway to add bands to modem?

I think I got a knock off c500 from AliExpress. I returned some other unit to amazon.

Everything seems to work okay EXPECT for the cellular.

I use T-mobile US. I talked to them. They told me my cellular chip in the radio only uses the 1900 & 2100mhz bands. (They see it on their system) problem with that is I only have one area (my house) where it uses the 1900mhz band for 3G. As soon as I go anywhere it goes to 2G (E) using the 1900mhz. I would need to add band 700 & 850mhz to have 4G LTE.

I am confused from all the posts I have read. Can the chip be unlocked to utilize the all LTE bands?

Can the chip be changed to a modem that has the correct bands already working? Am I reaching for a solution?

Who can check USB DAC is working after this edition of usb_audio section of original /etc/audio_policy.conf only?

usb_device {
sampling_rates 48000
channel_masks AUDIO_CHANNEL_OUT_STEREO
formats AUDIO_FORMAT_PCM_16_BIT
devices AUDIO_DEVICE_OUT_USB_DEVICE
}

I think handsfree should work.

Just replace default 'dynamic' words to static parameters.

In case of success, add sr and bit depth your dac supports.

Main

- Internal microphone can be disabled when using an external microphone, vastly improving sound-quality during calls. Be aware that you need to specifically ask for Ownice to provide you with a jumper-module when ordering your headunit, or to connect the wires yourself. It should be plugged into the following connection: https://xdaforums.com/attachment.php?attachmentid=4091227&d=1490655262, the red stripe shows where the jumper should be connected.

OK well I was given an unlocked at@t galaxy s5. I tried to put in my metro pcs simcard and it gave me an error. (Phone not allowed mm#6 ) but when I put in my girlfriends tmobile simcard it worked like a charm :confused: Just throwing this out there for whatever it's worth. I put the metro pcs sim in and when the phone booted up it presented metro pcs very quickly at the top left 9f the screen but then it disappeared and would only let me make emregency calls. I read that it could be my simcard could be tied to my other phones imei but I told the representative at the metro store that and she said that she switched the imei from the galaxy to my account. She said maybe the phone isn't unlocked but is that possible if the phone is at@t and the tmobile sim works on it? Could it somehow have locked itself to tmobile? Even if it did wouldn't I still be able to use my metro sim? Anyways any help would be appreciated thank you.

Memsscore http://mems-score.org/ benchmarks the (today mainly inertial) sensor subsystem of smartphones without expensive test equipment (right now just a printer is needed). But be warned, you need some time to understand and execute the benchmarks. Furthermore it interacts with hardware components (camera and sensors) which always has the risk that on some phones you will see issues.

We would love to get feedback from you on

- Does the app run properly on your device?

- Have you been able to perform the benchmarks? Is there something which would have made it easier for you to understand how to perform the tests?

- Any ideas for additional benchmarks are welcome. The requirements are reasonable reproducability and only minimal equipment must be required to perform the test.

Also the benchmark becomes more useful if we get benchmark score from many devices.

Many thanks

callwave works great for me

I use callwave (www.callwave.com), another free or paid service, depending on your needs and desires. It will send text, e-mail, or you can just call in to retrieve your messages (the free text and e-mail service includes a not-very-accurate speech-to-text; the paid version options are much higher quality speech-to-text for those that require it). I have mine set to send both a text message (so I know if I am interested), and an e-mail with the voice mail attached as a .wav file. This way I almost never actually dial in to get any messages, as I can fully delete them or keep them via my computer.

OK, OK. Just to clear things up. Simulsays is FREE!!!!!!!! Simulscribe does cost if you want your messages transcribed and sent in text format. But, all you have to do is set up your account which will ask you to choose a plan.

Just wanted to say that I've had a great experience with Callwave for months now. I believe I just signed up and selected the free service. I never call in to check my voicemail either now, but I think you can go on line and listen to the old ones in addition to having them emailed to you as a .wav attachment. The .wav files play through the phone speakers (like music) rather than the speaker you put to your ear on a call, but you can always call and listen to your VM like any other VM if you desire.

Also, they automatically gave a week-long free trial of their pay service where they transcribe your VM a couple of weeks ago. The free transcriber is pretty useless, but that one was excellent. Don't really need it so I won't pay for it, but I've missed it since the trial ended.
