I've run CPU-Z and it's seen as a 4-Cores and not a 8-Cores as advertised :eek:

I have to check, I don't think I have google maps installed yet (and to be honest I didn't plan to install it ...)

I followed the first steps but I was unable to make the OK Google to work ... But if I press the mic icon and say something, this something is correctly translated into words. I didn't continue after this.

I have also a C200 ... I'm not sure but maybe it's the first Android 6 Head Unit ... They have finished it in a hurry, it will improve in the next months I hope. BTW I didn't find how to use screen mirroring, or play music from an iPhone connected through USB ... It'll also come later I guess !

There is a bug on C200 when you enable the reverse camera during boot (after this the touch screen is not responding). On the C500 they did workaround the issue by only showing the camera image when the boot is finished :eek:
[Android Head-Units] vvs49:
a 8-Cores will be after the Chinese New Year, so I reported in Ownice.

I'm on the C200 it works, if there is no time, looking for some, the back and went - all I see (see disabling the rear end of the boot OS ~ with logo) and then there is no problem. :good:

I have a smart HTC One (M8) Dual SIM and everything is fine plays via USB

Thanks sylver78,

you were really kind.

The C500 is not the device that's right for me, Newmsy Carpad continues to be higher.

Thank you for the test that you did
[Android Head-Units] HVB83:
Thanks for the videos, very helpful!

I currently have a KGL mtcd unit that has some anoying bugs, so I'm considering the C500 now. Can you tell me a couple of things:

1) Does Tomtom work on this unit?

2) Can you bring other apps to the front of the screen while you're using the phone app?

3) Does Torque Pro work (on mtcd the light version works, but pro doesn't)?
[Android Head-Units] sylver78:
Hi,

1) Tomtom Go installed from play store is working on the C500 (on my C200, it was complaining about network problems)

2) I've not done any phone call yet

3) I've not installed Torque or Torque Pro yet.

Have anyone tested the SIM card slot at this time? I live in Denmark where we have 3G/4G coverage all over. Is there any reason why it would not work here?

Another question, would it be possible for one of you guys with the unit to make a video of Google maps running?

Mine finally showed up yesterday and I got it installed in my 2007 Nissan Titan last nite. So far, I must say I'm quite impressed. This is my first foray into one of these kinds of units so I don't have anything to compare it to, but overall, it seems extremely stable and works quite well. I got the steering wheel connections sorted out too (it's pins 12, 13, 14 on the 24pin AV harness. Red to wheel key 1, green to wheel key 2, blue to ground). I haven't been able to get it to pair with the ELM327 but my iPhone isn't seeing the device either so not sure if it's defective or what and I still need to connect up the backup camera. Going to head over to the AT&T store later today to see if they can give me a SIM card to test out the LTE. Google Maps works exactly as it does on my phone, and interface seems snappy even with several apps open at the same time. Glad I waited for the 2GB version.
[Android Head-Units] jefe.graves:
3G/4G

FWIW, no problem getting 3G on ATT's GSM network - just gave them the IMEI number and they gave me a micro sim card which I popped in and it recognized right away. Supposedly, this is a 4G LTE device, but it's only registering at 3G. Still 7-down/1-up will do.
[Android Head-Units] Flemischguy:
There are 2 micro SD slots, the left for gps and the right (media) for music, video, apps... But where do you put the sim card in? Is that in the right media slot and can you use the micro SD slot for the micro SD card if you use the sim card?
[Android Head-Units] Crimespree:

Can you tell how you measured this? Because I put an amp meter to power line and it used between 200-300ma (kept changing all the time. I should probably check it again) this is probably why it turns itself off completely.
[Android Head-Units] Chrishann:
I did it with a mini clamp meter measured directly at the battery. With my VW it takes a few minutes until the Can Bus puts everything in standby. So after about 5min I then max. 13mA.
[Android Head-Units] yurtesen:
I use Here Maps (settings menu doesn't open at landscape mode, otherwise works fine) or MAPS.ME. I am not sure about iGo because I didn't want to bother finding maps for it. I was surprised that it didn't have map download function. I am used to programs updating maps automatically.
[Android Head-Units] ely.soto:
Other option is for ownice to implement this. www.opensynergy.com/produkte/coqos
[Android Head-Units] yurtesen:
Did you measure how much your car uses when the radio is totally disconnected? Because most cars at least have some sort of alarm system, have to keep power to ecu ram and also the door lock receiver (comfort system on vw) should be powered up at all times. 13mA for whole car is OK, but if it is including the radio then it is incredibly low. I will put the radio to test again and post a screenshot.

The mini-clamp is not as accurate with the small measured value. When deducting deds mini clamp meters, I have the 6mA on the display then stood to the 7mA.
[Android Head-Units] yurtesen:
The meter is connected to unit between positive output of power supply and B+ wire.

Here the unit uses 0.6A when booting and it floats between 0.5-0.7Av after boot. This is without anything connected. Only an SD card and SIM card connected.

Once I remove power from ACC+ the screen goes dark on unit but it keeps using about 0.27A.

I waited few minutes now and it keeps changing between 0.25 and 0.36A.

I surely wouldn't want this unit to be on all day! I will try my other meter also and will see if unit gets warm at all after half an hour. I want to be sure that the meter is showing correctly.
[Android Head-Units] yurtesen:
[MENTION=7835555]Chrishann[/MENTION] your first two values in your photos look similar to my on and standby currents. I don't understand the last one. Are you sure radio doesn't turn off completely? When you turn the key the radio doesn't reboot? I will return back to you little later. My other meter days 250mA max :). I should try to see if it gets warm at all. You never know, maybe my meter is broken. I blew the fuse few times but it always gave reasonable results until now. I should also test without sdcard and sim card perhaps.
[Android Head-Units] Chrishann:
https://xdaforums.com/attachment.php?attachmentid=4055466&stc=1&d=1488140650

Perhaps the radio reacts differently in the car with the Can bus.

Note the measurements were taken before 2months.
[Android Head-Units] yurtesen:
[MENTION=7835555]Chrishann[/MENTION] I think canbus has no relation. I guess the logical thing is to wait for a 3rd person to to measure this. By the way, I left the unit in standby for 45-50 min and it was warm when I came back. So the meter is probably correct.

Now also tried with SIM and antenna connected. I am able to call to the unit when it is on standby. I think it probably cuts the power to screen and amplifier etc. but let's the unit work as usual otherwise. It is not a "real" standby.

This must be why the standby limit is maximum 1h. Although even 0.3A is not that much, still bad for your battery if you leave your car standing for a week.

Actually your car itself should be draining 10+mA or more normally even without the radio!

See:

http://www.popularmechanics.com/cars/technology/how-to/a5859/how-to-stop-car-battery-drains/

https://www.optimabatteries.com/en-us/experience/2010/12/what-normal-parasitic-draw

Because normal draw of the car should be at least 10mA-15mA without the radio, I think your amp meter is not working or inaccurate. Your measurement must be wrong. I can't think of any other explanation.
[Android Head-Units] Chrishann:
So now measured again. I put the radio on 60min. But after about 20 minutes. It was completely off and measured after 10min. As with you I now come to 265mA and afterwards when it is completely off to 9mA. Then I certainly determined 2 months ago a completely switched off device. With the January update, the standby did not work. Somehow I do not have 20min standby no matter what I set. I had previously a Joying RNS since the standby worked over several days with 25mA.
[Android Head-Units] yurtesen:
I am surprised that there is no power management at all in these devices. CPU runs full speed all the time. I bet they disabled all to make the device faster. Maybe somebody figures it out sometime.
[Android Head-Units] lotherius:
Seriously? Does it work with apps other than Torque Pro? What tricks did you have to use to get it to work?

Do you have a radio with canbus module? (afaik for rear camera, canbus is used only for detecting that reverse gear is selected)

Do you see notifications when you open your doors etc?

Do you have OEM camera on your car?

I believe the camera had some sort of 26pin connector. Is your camera connected to radio? If your radio did not come with an adapter, you may need to buy one:

[MENTION=7835555]Chrishann[/MENTION] , so it doesnt go over 30min for some reason, maybe you could try to disable the setting and then set 60min again, then try. But I think 30min is plenty, I am planning to put mine to 0 actually. In my opinion since standby current is so high, it makes no sense to let the radio on every evening when I come home or drive to somewhere. I can live with startup time. While 0.3Ah for 1 hour only is not so much, I think it will reduce the battery life eventually.

[MENTION=7902385]ely.soto[/MENTION] what is the problem with rear camera startup?
[Android Head-Units] ely.soto:
I just mean that i need to do a full 30 second boot before rear camera is useful. Almost everyone reverses out of park when starting their car.
[Android Head-Units] HVB83:
Even on a smaller car you have a 60 to 70 Ah battery, you can safely discharge such a battery to 60% without any negative issues. If you have your unit draw 300mah for 30 minutes, that's only 150mah. If you turn on your lights you're already using over 10 amps, not even talking about when you're doing a cold start during winter time. Modern cars have start/go systems which turn off at every traffic light, no problem either.

So if the longevity of your battery is the only reason why you would turn of the hibernation mode, I would say you have nothing to worry about. The additional discharge will add to the charge/discharge cycles to a very limited amount. The comfort of getting into the car after getting some groceries and having the system up and running right away would make it an easy choice for me.

Dear Ownice,

I have a C500 and am asking you to fix the boot time so that my backup camera turns on much quicker on full boot.

Note that sleep mode takes 300ma which is way too high for some reason for this processor. *Problem can be solved by lowering sleep electrical amp draw to below 100ma and then expanding time sets for sleep mode to 12 hrs and 24 hours which is an easy software mod. *This would fix a manor defect in the product.

Please advise. *Thank you.

[Android Head-Units] marchnz:
Im just keen on how the OP figures they will reduce the standby from 300mA to 100mA "easily by software" automagically. Given there is a second cpu and separate power supplies for it, very keen to understand. Very polite email however.
[Android Head-Units] ely.soto:
Not impossible. Better power management, disable certain chipsets during standby, etc. They can also implement a hypervisor kernel that produces near instant camera function without the android kernel being booted.

For android, sure. For the mainboard and MCU I doubt they implemented that level of control as MCU controls primary PSU not android.

Hello everybody! I found a way to change or disable boot animation.

[TUT] BOOT ANIMATION explained Here is general tutorial about boot animation.

[Mod] Bootanimations Here is little collection of animated car logos

[MOD] Boot Animations (Taking Requests)One more car logos collection.

So, changing boot animation. Be careful, you can brick your device if you will not be.

Boot animation changing with permanent root :

You need Total Commander for changing. You can use any file manager with root support, but I describe how to do it with Total. So:

Downloading or copy bootanimation.zip we want to install.

LaunchTotal Commander. It asks root access at the first launch, we need to grant it. Open folder /system/media

Copy bootanimation.zip from there, it is our backup. Next delete it from /system/media, during this Total will ask user permission for remounting file system. We need to grant it.

Copy here file with new animation, Total will ask permission for remounting again, grant it.

Call context menu of this file, press Properties, then RWX. Set RW attributes for Owner and R for Group and World. If you will not change access rights no new animation will be applied. During this Total will ask user permissions for remount again.

At the next reboot you will see new animation.

Here is all my actions and result YouTube

Boot animation changing with temporary root. Here we got root but it disabled after first reboot. How to do it:

Download or copy new bootanimation.zip. I guess you copied it to /sdcard/Download/

Install terminal, for example Android Terminal Emulator and launch.

You need to enter following commands:

forfan guoboneedav (now you will see "root" at the start of the command prompt)

mount -o remount,rw /system (here we remount file system for write)

cp /system/media/bootanimation.zip /sdcard/Download/bootanimation_backup.zip (doing backup)

cp /sdcard/Download/bootanimation.zip /system/media/bootanimation.zip (copy new animation file)

chmod 0644 /system/media/bootanimation.zip (set access rights)

mount -o remount,ro /system (remount file system for readonly)

You will see new animation at the next boot

There is one more variant of changing, but it is awful. You can make you device a brick.

Download firmware and unpack it under Linux with this C500.rar script Link to script

Unpack your system.img with Rom Helper, change /media/bootanimation.zip with new animation, pack system.img again and do not forget to set correct access rights to new file.

Pack firmware back and flash your device.

If you will delete bootanimation.zip on your device or will remove read access rights from it you will get just static "Android" string during boot, like on Andoid emulator.
