I did a factory reset myself yesterday. There's two described methods going around, but the one with the power button won't work. For factory reset to to settings / general / erase all content.

You won't lose the pre-installed apps, only those you installed afterwards. So yes, Sygic will be lost, but you will be able to download it from Play Store without additional costs of course. That way you can be sure that none of the apps or settings you changed has an influence in this case. So for that, be careful to install all apps again right away; if one of those is causing the issue you might have the same issue again.

VW can bus version standby power use

Hi!

I have the VW version with the can bus decoder built in. It has issues with shutting down. The red light in the buttons is always on. The radio has connection to the can bus, i can see car info and the unit turns on and off with the key. I have not measured the current consumption in "off" condition, but it will drain my battery in a weeks time...

I have tried to communicate with the seller, but I dont think they understand my issue.

My car is a 2005 Golf, it is very common that the can bus decoder needs upgrading to avoid battery drain when installing newer VW radios, could this be my issue? All inputs are welcome:)

Best regards from Denmark

I have a non working DAB. As described by others here in the Forum DAB works for aprox. 10 minutes and thereafter it looses signal and after a while it crashes and reboots the entire system. I have complained to Ownice in China, and they responded by sending me a new DAB app (funny that the new app is also version 1 like the old one) and telling me to update with the latest firmware (from Feb 20). I had that firmware already and the new DAB app just made things worse. Now it just says connecting - nothing more happens. I responded by making a claim in Aliexpress to receive my money back. Ownice have now told me that I should buy a new DAB module from them (at a discounted rate) and when I have received that then I should return the old one and claim my money back. This I have of course refused. Lets see what happens.

TomTom was okay, but I am not going to pay $22 a year for something my phone already does for free. iGo pissed me the eff off and was $7 for the USA. Everytime it told me I was going to fast it paused Pandora. Also a number of the speed limits were 5MPH over posted.

[Android Head-Units] lotherius:
Just got my Ownice C500 installed.

First impressions are overall good. Sound is good, screen quality is great.

Unfortunately, it will not operate with the OBDLink LX Bluetooth OBD. I specifically asked about this and was told that it did, but it does not. The OBDLink has a newer bluetooth version and uses a 6 digit PIN that changes when you pair, so the default 4 digit stuff won't work. It doesn't tell you the PIN, so if the radio asks you for the PIN (which this one does) rather than prompting you (like a phone would) then it won't work. It actually says the OBDLink LX is paired, but apps fail to communicate with it. Have to still use the cheap Chinese OBD that's much slower. I will have to live with it. At least the generic Chinese OBD connects with any app, not just Torque like my old HU.

Also, the "Car Settings" app will not open. You click on it, and it just does nothing.

Can't get the Metra ASWC-1 to recognize the head unit and configure steering wheel controls either, but that's as likely to be the Metra unit as the Head Unit ... I've had SWC with other head units using the metra adapter so I know it's possible.

Finally, there appears to be no "MENU" button functionality built in. I have the full touch. There's home, back, volume and power. But no "MENU"... for most apps not an issue. However I have one app that I very much wanted to use with my OBD, Auterra Dyno-Scan. It is an older design and *requires* use of the Menu button in the app to open one of the key menus to operate. Without a menu button, can't use the app. Period. Any way to get a menu button?

Going to search the thread to see what I find.
[Android Head-Units] Crimespree:
I'm sure it was me you asked. My 2016 purchase OBDlink LX works fine. It has a 4 digit pin. Pairing is finicky but it works.

Thanks [MENTION=2456913]vgabbott[/MENTION] I used a jumper in the back and it seems to do the trick for the external microphone. The microphone you suggested actually seems to be higher quality than what I had earlier, mine had half the size electret element and thinner cables. But I am not convinced it is the best solution when you have 3m long cable. I will try to get an amplified electret working with the unit. I need to wait for some parts. I will let you guys know how it goes....

Is there a wiki page for the c500 somewhere? it would be nice to collect useful information from the thread somewhere else because it is getting way too long!

Cant we make an entry to https://xdaforums.com/wiki/ for manufacturer Ownice and device C500 ?

I tried few cheap USB OBD adapters and adapters with prolific and ftdi chips work great with obd fusion and dash commander. Unfortunately I couldn't get any USB adapter to work with torque pro. But I blame torque for this, because I found in their forum that some other people changed to other software to get their adapters work. I don't really trust bluetooth adapters since well I don't want to risk random people connecting to it :p
[Android Head-Units] trap63:
try to update the firmware of OBD Link inside ODB Link apk or in Windows if not able to pair with C500. You can pair it on second request with 1234 pin code. Need to modify to 1234 HU BT key.

You can update firmware installing OBD Link apk on any Android device.

[MENTION=3394679]yurtesen[/MENTION], did you also increase the microphone gain level from the 1260-menu as described in the FAQ? Of course it is always best to improve the input-signal before you amplify it, but this seems to work wonders in some situations. Very interested to hear your solution in amplifying the signal on the other end!

There also seems to be another improvement option through the engineer menu [hardware testing / audio / speech enhancement ] and then setting Parameter0 to value 60000, but I haven't been able to figure out what this setting is supposed to do.

[MENTION=273616]HVB83[/MENTION] So far I had strange background noises when I used pre-amp. I should try to reduce the amplification from the unit I guess but earlier I couldnt find the setting in 1260 menu :) Also, I couldn't be sure if there was some problems with the cable I used. I have used the VW cable for VW dome microphone and I removed the pre-amp and connected electret directly but still had some strange noises. I will return back to it soon and try to have a more methodical approach because my first try was sort of random hoping it wold just work, but it did not :)

About speech enhancement, it seems to increase incoming call volume. I think it makes sense because all options in that Audio menu are about audio output. Also some small values between 0-31 may be resulting in larger values apparently (see elephone link).

http://www.patchworkoftips.com/increase-call-volume-android/2028/

http://bbs.elephone.hk/thread-7918-1-1.html

There are many web search results about it, none mention microphone. I will leave it as it is for now...

The FAQ is great, but can you convert it to WIKI page at XDA? The problem is that I (and probably other people) would like to add some stuff also when something is found.For example I tested some usb obd adapters and programs and I could have added something there if it was on WIKI.
[Android Head-Units] Mammûûth:
So anyone knows if the C500 use the 4g lte B3 B7 B28 and B20 ? Or which one does it use, I been searching but haven't found a clear answer yet xd.
[Android Head-Units] yurtesen:
All I can tell for sure is that it works with B3 because I have a connection which uses it and I see 4G working. But I think it should work with all the ones you mention because they are the main LTE bands.
[Android Head-Units] HVB83:
I looked for something like that, but couldn't find it. Do you have a wiki describing how I can turn the FAQ-topic into a wiki? (Yes, pun intended ;))
[Android Head-Units] vgabbott@gmail.com:
I bought USB obd2 adapter. Could not make it work with either Torque or Dash command. I noticed that when plugged in that it took a lot of juice and was hot to hand, even with ignition off. So I think the 8mw BT adapter is better solution if you want to have obd avail at all times.
[Android Head-Units] yurtesen:
I think there was something wrong with your adapter. Because I tried at least 4 adapters and none got hot. I have adapters with CH340, FTDI, Prolific chips and CH340 does not work only. I made a harness with internal OBD port to my radio. There was the K-Line(pre canbus car) wire coming to the harness in my car so I just used it. Seems to work great with the radio and when I turn off the ignition, power usage is 0.
[Android Head-Units] Akhlan:
Please could you give me the name of your HDD, I'll buy the same... And the name of your music application so ;)

Well, I think there is no magical way to convert it. But I started a page for you to continue. I copy/pasted some stuff from your FAQ also there. Added Ownice as manufacturer to wiki etc. I am just not sure why my page entered 'pages with broken file links' category...

I am hoping now that everybody would chime in and make it nicer:

Hi!

Hi all!

I've read (only) the first 40 pages of this topic and i'm interested in buying this product Ownice 4G SIM LTE Android6.0 4 Core 2 Din Car DVD GPS Navi For Mercedes A-class A170 Avantgarde W169 from 2004 from aliexpress .

Quick question for the owners: overall, is it worthy ? After those few month of usage, do you recommend this product ?

Thank you !
[Android Head-Units] vgabbott:
The answer is that it depends. I am happy with my unit. The one major drawback at the moment is the backup camera delay. All of these Chinese units have some issue or another. The c500 for instance only has 3G available in the United States. So if 4G connectivity is high in the list of your priorities then if you are in the u.s. this unit may not be for you. Another issue is how much this unit cost in comparison to other units on the market. I am sure that the higher cost units are probably better. All I can tell you is that at this price point I would purchase this unit again even though it has known issues. Hope this helps.

[Android Head-Units] HVB83:
It depends, as vgabbott says all of these units have bugs, some of them bigger, some of them smaller, some of them will bug you and other people can't be bothered by that particular issue. In the FAQ-topic most of the known bugs are listed. Some people claim that Joying is the best around, but looking at that topic I see a lot of issues that would annoy me endlessly.

It all comes down to personal preference. Just see for yourself what issues each unit has and make up your mind if you could live with those.

If they manage to fix the camera delay issue, I would consider the C500 nearly perfect.

Thank you very much for your feedbacks!

I decided to order it, now it's time to wait for delivery :D

In Romania an original command unit for Mercedes Benz is about 4000 euro; also, just a bluetooth adapter compatible with the cat kit is about 350-700 euro.

So the budget for the C500 was not a problem :) Also, if there is a little delay for the back camera, no problem for me.

Hi, thank you for posting these. I have the same problem with the DAB+ app crashing (info in an earlier post in this thread). Tried all apks in your link yesterday.

They all installed ok, and all of them were able to find available DAB+ channels. Then 50 % of them crashed directly after channel search. The remaining half worked fine initially, but crashed after some time playing (typically 5 to 10 minutes).

The latest version (named just Dabplayer.apk) had one interesting feature. During channel search I saw that it supports Norwegian Special Characters (Æ, Ø, Å). In all other APK versions I have tested these characters are replaced with Chinese symbols. Unfortunately, this version of the apk was among the group that crashed directly after channel search.

(I have a C500 with Ownice's own DAB+ adapter, the latter listed as "OTS022")

On Xtrons Octa Core (I moved from C500 after 2 weeks) first apk ver 1. and 2016 function very well but sound is stuttering (minor issue) only when set apk in foreground (minimized). I asked to revise software as it isn't an issue related to unit or stick thus it functions, they gave me the latest you tried. Still crash for me too after channel search.

I noticed Xtrons yesterday, I wait now for a new version, they need to revise as in some European countries analogic way is out since 2017 (North Europe countries I think).

Some of these producers claim to be returned the head unit or stick as faulty.....but it is only a time loosing. When all Europe enter in DAB system if they don't/won't revise the software, no head unit might be sold. It's a time question (for Italy next years will be on the full migration from RDS to DAB+).

It remember a bit the FM-RDS discussion, in other countries don't understand that RDS in Europe is not for "advertising" transmission, we receive wheather forecast , traffic messages (no need of vocal TA), public warning and so on. DAB+ is a European mandatory Regulation for transmission in next years.
[Android Head-Units] thitland:
Just to give an example of the transition to DAB. Here in Norway analog radio distribution (FM) is gradually shutting down this year (2017), and we are moving towards DAB+. The changes have been heavily debated, but it is happening. As you say - hopefully the producers will make a better effort trying to solve issues like this when the number of users increases. I have just sent a new mail to Ownice/Winlink asking whether they will be looking into these problems, but I'm not too hopeful for a reply. They have not replied to my latest e-mails.

By the way, I have noticed that my DAB+ apk seems more stable when I keep it in the background. For example if I launch it, select channel, and then launch my SAT-NAV on top.

Actually I asked a vendor from ownice on whatsapp and he said the same, let's wait and see.
[Android Head-Units] lukas.elk:
I also have the white screen problem. When I start the car after couple days the screen is white. When I start it after couple hours it's ok. Last time it happened seems that pressing the PWR button for a long time helped and the unit started properly. Although when it starts all my paired BT devices are gone. Same happens when you save the system setting and device gets rebooted. This makes me think that it might be some kind of system memory not being kept alive? My car doesn't have a BATT 12V+ in the radio harness, only ACC 12V+ so maybe that's the problem? But then why would it start normally after couple hours but not after couple days?

[Android Head-Units] trap63:
the apk you mention crashes both on octa core MTCD too (see thread). It's a software issue they all won't solve on new platforms as they are seller not producers or developers. They suggested to return stick or unit, a nice way to loose time and not solving issue.
