60mA is not much and it is reasonable to assume that it should survive it. But you have few options if you want to avoid using it. Option one is using the backup/reverse light wire, you can just wire power from the light bulb or reverse switch in car if accessable. This would be optimal because it would power the camera only when you use it. If you don't mind it being on always when you turn on the key, you may splice ACC wire also..

What I did in my car to get additional power was to use a 2EUR relay from AliExpress "12V One 1 Channel Relay Module Board Shield with optocoupler Support High and Low Level Trigger". I had to remove the PWR led from the relay so it wouldn't use power when the key was not turned on. If I remember correctly, that used about 4-6mA from input. After that, I didn't have to bother about these issues anymore....

By the way, you didn't comment about my wiki conversion, did you see that? -> https://xdaforums.com/wiki/Ownice_C500

Thats what they told me too. First they wanted me to return the DAB device and then they would send me a new. I told them that it would cost USD 20 to send from Denmark to China. Then they abandoned the device and gave me my money back. I have a Joying (Intel based) and on that the DAB adapter with the same/very similar app works.

Maybe a better reading can help chinese to understand if they want to sell in Europe or not, here the Norway since this year is only in DAB+, within the end of year all Sweden and Finland. This means that any Head Unit with FM tuner is a stone for these countries, none will buy if apk and stick doesn't run. In Europe the two systems (RDS and DAB+) are still living toghether thus all countries aren't aligned. In next future the FM system will cease for migration in, as happened to old VHF/UHF analogic TV. Here the two systems

will not survive toghether

. It's easy understanding for deploy the apk in a stable way. For Switzerland by the end of 2019 all FM stations are to broadcast digitally on a DAB+ platform.

[Android Head-Units] yurtesen:
This information is incorrect. Norway is the only country which has "only" DAB in the world and Sweden has only 35% coverage and in Finland the coverage is 0% since 2005!

I think the problem is that it is not as easy to switch to DAB compared to digital tv, you could just put a set top box to receive digital tv broadcasts. It was cheap and easy to implement. It is not easy to add this functionality to most existing radio. DAB is costly for customer and in most cases not worth the effort. It will take 6-10 years to have enough devices out there which can receive DAB broadcasts.

That said, I would try a 3rd party USB OTG device. For example an RTL2832U based USB stick or another with some software (it may even be possible to receive DVB-T broadcasts with same hardware). I could receive with another USB stick DVB-T broadcasts in my unit, but we don't have DAB here.

Always tried with RTL2832U stick, signal receiving quality is not so good like the Xtrons stick (author explains the reason in googleplay description), Wavesink plus.apk received last update some years ago, sometimes crashes and need to reinstall it again.

About DAB+, in Italy all over the Highway service including South Italy you receive it and it is available for 85% of population, nowaday it's a need. Mainly the stock head unit installed on medium level cars from constructors (on sale in Italy) get DAB+ as standard. This is that they don't understand. You find DAB+ on a Kia i20 now in Italy or FCA 500L, Toyota Auris, Renault Clio, Abarth 500 and so on. Why change stock head unit if replacement is not operating as well as the stock one? we aren't discussing about Xirius XM system which refers only to US, mostly on monthly payment.

You may have had some interference because other people seem to get it work. See:

https://www.reddit.com/r/RTLSDR/comments/2vpmw7/dab_in_car_with_rtl_sdr/

Yes, maybe this year signals will reach to 85% of population in Italy. But the question boils down to how many has receiver to listen to it. Then it is probably not so nice to force people to buy new radios, but well I don't know who pays the government officials to force citizens to spend money and who profits from that :) In either case, it is outside of the scope of this thread... My point was that DAB is still not a widely popular technology.

Yes, I also do not understand why I would buy 2016+ model car with top of the line touch screen radio which include DAB etc. just to switch it with a cheap android radio next day. I must be crazy :) But, I looked around, for example 500 withDAB version costs 350GBP more... http://www.telegraph.co.uk/cars/fiat/fiat-500-review/ Toyota upgrade costs 230GBP http://blog.toyota.co.uk/switch-on-to-dab-digital-radio When you get DAB in your brand new car, you pay as much for it as you pay for whole C500, so it is surprise that C500 even works this well considering the cost of it.

To sum it up, I understand your frustration but what I meant was that DAB is not that widespread and I wouldn't expect so cheap chinese unit to support it to begin with. If C500 costed 800+euro, then I would have complained for sure, but for 250euro unit it makes magical stuff already. But I am sure Ownice will get it working soon, if not in this model, maybe in a future model.
[Android Head-Units] thitland:
Hi! It is very cheap compared to head units sold by the car manufacturer. But after all, in my case Ownice lists DAB+ support as an argument for buying their C500 head unit. And they sell their very own DAB+ adapter, claiming it works with their head units (that's the one I bought). So I think we should be allowed to expect them to work...
[Android Head-Units] kaymm2:
Every time I start the C500, it says Optimizing app 1 of 1, then starting app 1 of 1. It adds about 5 mins to the boot up time. Anyone know why this is happening?
[Android Head-Units] yurtesen:
You have an app which is not optimized/compiled properly for an unknown reason. Your system tries it every boot. I would first try to find out which app from logs or start removing large apps which were installed from play store and reboot after each to figure out which one is the problem. You may try to compare which app is missing is dex file in cache also. Looking at log and checking cache is maybe rather technical so you may want to simply remove apps one by one until you find the problem program.

@vgabbott , did you consider trying another antenna for 4G? Just last week, I was testing some stuff and I had really bad signal with ownice antenna, also with another Chinese antenna, unit defaulted to 3G. I eventually managed 4G but in my phone I get 10-15 dBm better signal compared to ownice.

So, I was thinking, are you sure that you don't get 4G because of supported frequencies? Do you know which frequency your provider is using at your area? You can see this from your phone if you have 4G in your phone.
[Android Head-Units] vgabbott@gmail.com:
The C500 does not have the US frequencies built in for 4g. Kind of big oversight. The frequencies are called out in this forum on prior pages, none of which are deployed by att, Verizon, Sprint of T-Mobile.
[Android Head-Units] yurtesen:
AFAIK all the frequency suggestions were guesses in this forum. All I know for sure is that it supports B3 because I used it. Do you know which band is used in your area?

As I mentioned, all of a sudden I had 3G only in my c500 where I have almost full signal at my phone. It appears the problem was the antenna somehow, moving the antenna gave 4G with minimal signal in c500. It may as well be that the antennas provided by ownice does not perform well in the frequencies used over there.

Anyway, I dont know how to be sure about the supported frequencies so... it was just a possibility...

[MENTION=2456913]vgabbott[/MENTION] , you seem to be correct. I checked the device with an MTK engineering tool which can get the bands it supports and bands used in USA are not supported. I have updated the wiki page with all the bands tool showed for GSM, UMTS, 4G -> https://xdaforums.com/wiki/Ownice_C500

Can you install MTK engineering tool from store and see if you have same numbers? The values are at MTK Settings -> BandMode -> SIM1 . I just wanted to see if the values I saw were not limited by my SIM card or something like that....

I don't understand what is up with rooting this unit either. I've tried the instructions in the topic, through which several people claim they successfully acquired root, they didn't work for me and it seems quite a lot of people are experiencing trouble in this area. I've asked for assistance several times, but up to now nobody has stepped up. I'm sure there are some Linux-gurus out there who should be able to help pinpointing the problem.

On the other hand, guys like Trap63 have been able to get it working, otherwise I would have doubted the authenticy of the rootability-claim all together!

---------- Post added at 01:36 PM ---------- Previous post was at 01:30 PM ----------

On this unit, the GPS and 4G antenna's are swapped very easily. This can lead to very strange behaviour, which you won't really notice at first. GPS will function, although you will see that the number of satellites and the signal strenght is greatly reduced, causing regular loss of a fixed position. Same goes for the 4G-signal, it's still working, but often leads to slow speed and loss of signal.

But the most apparent issue is that the unit reboots, sometimes after 2 hours, sometimes 3 times in a row.

Overall my unit is very stable, so if you experience any issues and didn't install many 3rd party apps, I would check to see if you got your antennas connected the right way. (I know, not very likely, but still worth to check if you're not 100% sure)
[Android Head-Units] trap63:
So, some writings about Rooting process:

#1 reset device to factory default with no install of any apks, no customization in hidden factory settings

#2 flash with latest release available V39, SD or usb stick FAT32 ONLY NOT LARGER THAN 8 Gb PREFERABLY!

#3 after reboot

DO NOT CUSTOMIZE UNIT

#4 copy ARM64 from a FAT32 SD onto device main Dir / or download from here https://drive.google.com/open?id=0BxORzE28l_E3bmRrWVFQX1RMY28

"EXTRACT ON WIN PLATFORM"

#5 run Terminal Emulator for Android as explained in topic about "HowTo"

#6 do it preferably with

a wireless keyboard

(Logitech about $6 it's good) if not experienced command line user (try to find letters for command line on keyboard > , : ? = - before starting to run)

#7 check each digit you write, even

If fails 'cause any "ARM64" or file is missing check again DIR contents, reboot unit and retry.

IF FAILS AGAIN FOR MISSING FILE CHECK YOUR WINZIP/UNZIP/WINRAR/RAR EXTRACTOR.

For Mac Users:

if Mac OSx will decompress itself the file after downloading sometimes you will find incomplete extracted directory .

Check your trash bin to recover unzipped file and decompress again outside Mac OSx GUI or with another unzipper program.

[MENTION=273616]HVB83[/MENTION] When you open a terminal window and write `forfan guoboneedav` you become root implicitly. You can see this from the last character of prompt changing from $ to #. If, after this, you are not able to complete the process, you must be doing something wrong. If you copy/paste or send screenshot of your terminal screen after entering all the commands, or send any errors you receive to us. We may be able to help figuring out where you are making a mistake. BTW I copied the root instructions to c500 wiki page for easy access.

Explanation of the problem with GPS/4G ports. The GPS port provides 3.3v inline power for the active GPS receiver. If you connect 4G antenna to GPS port, you basically short circuit it and this will cause regulator to overload and eventually reset itself etc. When the 3.3v regulator resets itself, it may cause random resets if it was a common rail for other parts of the circuitry.

I think this is hardly a fair comment. I don't think "Bob" (who is probably a low level support person) needs to know everything, what is important is that he is trying to communicate our problems to a person inside winlinktech who knows how to solve these problems. By antagonizing "Bob" you are just annoying the only person who is trying to help us.

[Android Head-Units] yurtesen:
I don't get your point. I can call to tech support line of any company producing Android products and I may find people who does not know what is "root". This does not mean they are bad companies and I would say most companies do not really want you to root their product and brake it anyway.

As a matter of fact, it means they have some brains that they do not put their top engineers to tech support duty. I would rather prefer that Ownice/Winlink engineers are working on fixing actual problems, than sending forum posts to people about how to root their products. If you think about this, I am sure you can appreciate it.

Agree....but there is no need to "dismantle" Android 6 universal specs with unstable code not needed, if you want to customize it don't break code (see BT issue/locking or WiFi handshake....) or hidden toggle in some default menus. It names

not Chindroid. If you broke it tell how and where to repair. not to return the unit to solve an issue as none is beside the road corner about 2 miles. About help on issue I will wish to introduce to you what they wrote and coded in a first fully perfomant apk such as DAB Player to reach instead an hungry CPU resources eater apk and stuttering apk.

After that I well explained above how to root and I recorded many successes, now, in other topic.

[MENTION=1024529]trap63[/MENTION] , you are changing the subject my objection was to how harsh you responded to "Bob".

But you are still exaggerating. About Android, they need to modify it. For example in normal android, you connect your phone to bluetooth speakers, but in car radio the radio is the speaker (simply this may require changes already). In addition, Android already is not perfect and many people have bluetooth/wifi problems with their mobile phones even.

About returning the unit, it is not like Ownice has a huge network of repair shops and spare parts around the corner. Your expectations are unrealistic. This is a cheap device which is sold with minimal profit, they can't even afford such stuff. Especially not with so small user base.

If you want support on the corner of the road, you can pay the 4000+euro (see this) and buy from your car manufacturer. Why didn't you buy from your car manufacturer? If you buy 4000+euro unit and come to complain about a problem, I would totally support your opinion :) but for Ownice, you seem to be having unrealistic expectations.

About DAB, this was discussed before. I agree that it should work but it is a new thing for these devices and problems are bound to happen. Use a USB stick! https://www.youtube.com/watch?v=cNlHinR6dhc

About DAB apk, here you can download and try their APK modded and revised from a friend of us last week.

It includes Record option, PTY toggle, not stuttering sound when minimized, reduced CPU resources/overload request.

Some variations in manifest and much more, black wallpaper graphic, frequencies detail and name station label on top.

Thanks to the wonderful people on this forum, I've been able to root the unit and install the audio_policy.conf file from this topic: https://xdaforums.com/android-auto/android-head-units/joying-2gb-sofia-headunits-common-t3577217

Together with a Behringer UCA202 DAC, I now have a working external USB DAC connected to the C500, including volume control.

So far I've succesfully tested with Poweramp, Youtube and Tomtom. Radio I haven't been able to test, since I took the unit out of the car.

The handsfree I tried very briefly, but didn't seem to provide audio output through the DAC. This is nowhere near a conclusive test. In my particular situation this can be overcome as long as audio is then output through the the pre-outs (which I haven't tested yet), since my amp has a separate input for handsfree.

Very happy with this, as I didn't expect volume control to work right out of the box.
