Sleep time

Ownice has come bake to me with this solution to the "SLEEP TIME' issue. I have tried it and it did NOT work for me.... I will post what they said please all who are having a issue try it and then let me know so that i can go back to then and show them the result.

Q how to set and save the standby time

A: 1. Set the standby time, click the BACK button to home page.

2. take out of the key, car radio will be turn off. Then wait 1-2 mins.

3. turn on the radio, after the radio finished boot, (you can operate the radio), then click the RESET,

The radio will reboot, after it finished boot, standby time will work.

Please let me know
[Android Head-Units] ely.soto:
What is RESET?
[Android Head-Units] DropperGK:
On your unit there is a little "RESET" hole that you can put a pin in and put reset the unit
[Android Head-Units] Chrishann:
I now have the current firmware.

The DAB + app has been deleted and is also not with 1260 menu.

Also the standby does not work properly. Sporadically it goes but to 90% it is not.

Interestingly that iGo update I did worked perfectly it fixed the non working voice prompts, at least until the c500 rebooted, now voices don't work anymore. Boings and dings and hoots all work just no voices.

It looks to me like it is something to do with the version of iGo that Ownice have installed, an upgrade worked until a reboot forced it to use old files. I know its using the older files because its using changes I made.

How do you completely clear out everything of an app so you can start again?

Gormiza, my USB is working after the latest firmware.

Nissan Qashqai with c500 and no can bus

I bought the c500 ( the Nissan Qashqai edition) BUT no can-bus or steering wheel buttons work! Cabling made as manual .Car : Nissan Qashqai Accenta Diesel 1.5 Model J11 (2016) /// ---> Any ideas???

ok I suppose you suggest not to connect the black box that sais " can-bus"? I tried that but again no luck!
[Android Head-Units] halloj:
[/QUOTE]

I just said that it might be resistive rather than can-bus driven. In such case you need to connect to the cables saying Key 1 and 2.

Try to ask at any Qashqai dealer for advise or the seller of the C500. The can-bus many times does other things rather than SWC.

I don't know if this below is appropriate.

[Android Head-Units] halloj:
I'm not sure what you mean, but look at the schematic I provided. There are normally two cables+common ground

coming from the SWC if they are of resistive type. They would normally be connected to key1 and 2 and common ground.

[Android Head-Units] spyone:
I saw the schematic but key1 and key2 refer to specific cables? or specific plugs? My car has definatelly can-bus and there is a plug (with many cables) that controls among others the SWC. This plug is connected to the c500 but no SWC

It seems the C500 prices have been temporarily been dropped between 20 and 35%. Could this be an indication that the release of an octacore is imminent?
[Android Head-Units] Crimespree:
I seem to be having an issue where the headunit forgets all Bluetooth pairs after a couple of days. Not sure what triggers this, but all paired devices disappear from the OBD paired screen. :(
[Android Head-Units] yurtesen:
I think the prices are the same as before. I read they come after Chinese new year here in this thread. But I don't know why wait. It probably won't make a huge performance impact but will be more expensive.
[Android Head-Units] HVB83:
This was the reply I got from the Aliexpress seller, regarding my question:

You never know how much truth is in there since some of these guys will tell you anything just to make a sale, but I'm thinking of just buying the 4core unit also. Lots of guys here seem very satisfied with the way the unit works, so it doesn't seem to make sense buying a unit which might or might not be faster and bring new bugs into the game once again.

Stuck CD

I'm unable to eject a CD that is still in the unit. Eject button does nothing and i get the "Corrupt USB ATAPI drive" error. any ideas as to how to get the CD out. Its somehow software related.. there is nothing wrong with the hardware.

---------- Post added at 10:36 PM ---------- Previous post was at 10:32 PM ----------

Yes, i concur.. also having the same problem.
[Android Head-Units] Old Grey B:
What have I done?

I have been playing around with iGO to try and get voice prompts working but now the unit will not recognise any microsd card, it says sd corrupted and asks to format it giving two options, one to be able to transfer files between devices, presumably FAT32 as I can read and write to the card on my computer, but still saying corrupted and not accessible on the C500 headunit.

The other option is presumably an android file system as the headunit sees it as OK but my computer doesn't even know it exists.

Is this something I have done? Can I undo it?

I left it an hour and rebooted and it all came good, go figure.
[Android Head-Units] yurtesen:
Did any of you tried to use SD card as internal storage? I tried to set it up but after format it asks about moving the data then it simply says not enough storage and fails. I tried 2 different SD cards, one 64GB and one 2GB (after full unit reset, it said data to be moved was less than 1mb). Any ideas?

Actually I would like to use SD as external SD but apps do not seem to see it. I installed Here map application and it only sees the internal memory, but why?

Also 4G antenna connector near the GPS connector is the only one which functions and the far one which is more towards middle is not used (perhaps due to some setting it is disabled?) Can anybody confirm this?
[Android Head-Units] ely.soto:
4g antennas use MIMO diversity. Are you sure it doesn't work? Maybe MIMO is disabled.
[Android Head-Units] vicom2:
Anyone having issues with the Sim card? Mine wont lock in the slot, it just pops out.. Am I missing something.
[Android Head-Units] yurtesen:
Perhaps you are right. It may be possible that it is only used for 4G then. Because when the device is on 4G network, I can quickly move the antenna from one port to another and then it appears to work from middle antenna connector. But only if there is already 4G connection and signal is still slightly weaker... I assumed the chip would have used the antenna with best reception for any technology, 2G, 3G and 4G/LTE. I guess I am wrong, it is perhaps using it only for 4G.

In addition to my previous post, MAPS.ME aplication is able to use SD card for storing maps while Here maps can't. I guess I will live with it

Thanks for helping out :)

---------- Post added at 05:16 PM ---------- Previous post was at 05:10 PM ----------

I had a similar issue. First make sure that you are inserting the card correctly. I figured this out by using a flashlight and checking where the pins are in the slot. Then I had to push it in with a flat head screwdriver because it needed to go in quite deep to click. I didn't have long enough nails I guess. I had to try it few times before I could get it stay in there. It is not so easy. I guess thats why all sellers keep telling dont put it wrong way around or it will be difficult to remove :)
[Android Head-Units] ely.soto:
You have to put it in the right direction and push it in further than the sd card.

Sim card should be interface down and notch out, then carefully use a tool to push it in far enough. I couldn't do it with my fingers like with the sd card.
[Android Head-Units] lucoro46:

[Android Head-Units] ely.soto:
Well there should be a rear camera rca video input and a back wire you can connect to. At least my version has that. If you have CANBUS and it is working, it should detect that you are on reverse gear as well.

Do you have any of that?

There is no cable with the name of back
[Android Head-Units] arnljot:
Back is a reverse signal. Some car radios get that as a separate signal cable from the car. Often but not guarantee to be a purple cable.

If that's missing, many wire the car radio to the red+12V power cable of the white reversing light in the back. That's what you can use the red cable running along the video signal for.

Ownice C500 FIRST USAGE AFTER INSTALL REVIEW

Happy!

I became

crazy

with Xtrons Android 5.1 and all MCU's updates and several (10) Malaysk ROM. (thanks for support [MENTION=3590033]Malaysk[/MENTION], this platform Rk3188 is a ****ty platform and the job to bettering he done is invaluable ).

Results:

#1 no root , Sygic Navigation and TomTomGO

install with no trouble

, very fast (for serial too long or whatever....on 5.1 you was able to install only Sygic);

#2 Bluetooth frame 100% WORKING! it pairs both my Samsung Galaxy S7 Edge (SM-G935F) running Android 7.0 and ODB LINK LX

genuine

for DashCommand;

#3 Both DashCommand Pro and Torque Pro operates with no issues and ODB is immediately recognized.

#4 USB Dongle DAB+ of Xtrons still operates as driver are onboard!!! no need to buy another one if you get the Xtrons already;

#5 my external Parrot microphone works very fine with C500.

#6

unsatisfied about sound and EQ

, it was better on RK3188 platform but was the only think it rans, JetAudio Plus Pro will help to gain a good sound.

#7 LTE 4G , the best.!! H3G in Italy works fine.

My rate is positive, AAA+ it seems unbelievable to manage the HU with all features without modify something...

With the bluetooth issues causing obd-software incompatibility and inoperability of the system during phone calls, long serial issues causing Tomtom and the likes not to work, a lot of core features are affected by serious flaws. Such a platform cannot be designated as "great performing" if you ask me.

At least I'm happy with Trap's experience, since he knows the specific issues these Chinese units can present since he's owned a MTCD if I recall correctly. The items he addresses are the shortcoming that bug me the most.
[Android Head-Units] marchnz:
Just to clarify, I see listed software flaws and BT implementation - and not rk3188 SOM/CPU specific - Ive not experienced the serious flaws on rk3188 (although I dont use ODB) - at least on my JY MTCD.

Android 6 probably makes a difference, but the SOM i very much doubt px5 performance be significantly greater than the px3/rk3188 where SOM has 2gb - in terms of lag and SOM performance as a head unit.
