I received an Android 9.0 CSN2 unit, it works nicely but is somewhat "locked down". The apps for developer settings didn't work anymore. I have not tried rooting, it sounds risky. RootChecker indicates there is an su binary present, but Supersu says it isn't rooted. Tasker plugins don't work, it goes back to the task screen when I try to setup a configuration. I miss being able to keep selected apps alive (dormant) during sleep, the "com.hiworld.*" trick (from MTCD) doesn't work. The system activities for audio sources (mp3 player, radio, etc.) are all in the same package, and those are kept alive. Google Maps however is not, so when resuming one has to at a minimum press the "start" button, and after a stopover one must reselect the destination being navigated to.

The biggest positive is GPS accuracy. I checked with GPS Test while driving over a bridge and it indicated accuracy of 2 feet.

This isn't intended to be a rant, just information. I didn't want to open the unit up (at least not yet) so I can't report what the hardware looks like.

Update:

Looking better now. Tasker plugins apparently work, with the latest Tasker update. And I found ADB (over wifi) has root access.

Further update:

I think the shutdown scenario is not actually that bad, I may have the yellow and red wires reversed. Why are their locations on the ISO connectors inconsistent?

However the Tasker plugins usually fail to allow configuration.

Thanks for the report [MENTION=7329495]xdamember2[/MENTION]! If you could post some pictures for the interface it also would useful there :)

For now we suspect that android 9 units have different hardware on the mainboard. MCU is fully compatible between android 8 and android 9, so MCU from this thread could be installed on your unit, but not android part. Also I have android 9 firmware, but it can not be installed on andriod 8 units. At least till this point we were unable to do that. Once I find the pictures of hardware, I'll write a summary about that.

Just wanted to report I ended up with CSN MCU when I purchased this for my 2014 Mazda 3. Pretty sure it's a Klyde unit.

It's been giving me quite a bit of trouble and the seller isn't very helpful, so I'm glad I was able to find this and some resources to hopefully fix my issues. I'll report back once I've finished updating and connecting some things.

I'm fairly certain my steering wheel call and hang up buttons (TEL (+) and TEL (-) on Terminal 2 I believe) are not connected at all as the adapter only makes use of the plug that goes into Terminal 1 (on the left) but I'm not sure how to connect them looking at the wiring diagrams attached. Any ideas?
[Android Head-Units] joehjay:
how is possible to change the boot Logo 1 of the unit? thanks
[Android Head-Units] Kenlider18:
That's sad, but I'll try to negotiate with supplier, a final questions do you know what can possibly caused this problem?

Thank you very much for your help
[Android Head-Units] _yuzo_:
Just a factory defect. The amount of them in Klyde units is really small, but they still are possible (as well as with iphones :) )
[Android Head-Units] Kenlider18:
Thank you very much for your help, one more thing, supplier is not responding, but i dont want to throw away my radio, do you know where can i buy a new coreboard?
[Android Head-Units] _yuzo_:

Friend, after reinstalling the radio to have at least rear camera, and removing SD card to use it in my phone, guess what? The stupid radio worked, don't really know why but radio is working again!! Can you imagine?
[Android Head-Units] _yuzo_:
What can I say:

- I can be wrong when trying to do a remote diagnosis;

-You never told about inserted SD card;

- We studied a new case and you are lucky as you do not need a new coreboard:)
[Android Head-Units] Kenlider18:
Yes a new failure mode, but I learned a lot with your explanations, at the end it was fixed by removing SD card, I didnt even remember that SD card was installed!
[Android Head-Units] bkran:
So the seller sent me an update file for the bluetooth with the following instructions :

Copy to U disk, enter factory setting and fill in password:9271111, click WQF210 Bluetooth software upgrade, it will be upgraded automatically

This password is not accepted and when I asked them again I got this response :

927111 as password

this does not work either.. I go to car settings, factory settings and enter this password

the password of factory setting is 126

I asked again but their responses are extremely slow and as you can see don't work. Has anyone done a firmware update on the bluetooth module only?

Also I assumed that U disk is a USB disk, maybe it is something else?
[Android Head-Units] _yuzo_:
All the updates from the factory related to Bluetooth did not have any effect. If you trying to solve the problem with a weak microphone, just de-solder the internal and use external to have an acceptable voice quality.
[Android Head-Units] bkran:
My bad I didn't quote my initial post, my problem is that bluetooth does not work some times and I have to reboot the device to get it working. Sometimes I just need to connect to my phone manually from bluetooth settings. The vendor send the update to solve this problem.
[Android Head-Units] editmaster:
Looks like I've found the right thread. I have unit from seller skyshadow. 6GB/128GB version. Unfortunately I can't tell what MCU/firmware whatsoever, because my device boots to emergency dailer only.

I can hold the reset button indefinitely, but nothing will blink or otherwise indicate it might want to go into recovery.

Skyshadow sent me some files and instructed me to connect Key 1 wire to ground and boot.

Radio does try to update and quickly says "finished". But then boots to emergency dailer again.

Radio had trouble connecting to cell data so I played with SIM Pin lock/unlock. Unit would not accept correct pin and I ended up in that stupid dailer...even without a sim in!!!!

Any ideas?

Edit: I've just tried and copied kupdate.zip and the other file to a USB stick. Radio says "Update finished". I think it doesn't even looked at the stick. Weird.

Hello!

I am confused about what version of Android is currntly installed on my head unit. I recieved this unit about 4 weeks ago.

The unit says it is running android 10, but I have read that this might be faked? What rom version can I update to please?

Thanks,

[Android Head-Units] _yuzo_:
Mainboard (motherboard) is the same for all PX5, PX6 and PX4. The difference is in DSP on it and in the CPU on coreboard. So you have PX6 according to your specs.

Hi all, do you also have the problem that the radio does not go into sleep mode when the engine is turned off? Is it possible to set this?

Also, the radio does not seem to go completely off but in sleep mode. Because of this I had a dead battery and had to bypass the car.

Maybe someone has hints if it can be set that the radio goes completely off when the engine is turned off so that no power is consumed.

Disconnnect 2 plug wireless form canbus, or maybe you set it never go to sleep in settings.
[Android Head-Units] mobi.binary:
Hello criszz,

thank you for your support and reply.

Could you please advise what disconnect 2 plug wireless from canbus mean?

Do I have to disconnect a plug from the canbusbox or just a pin in order to change the canbox pinout?

How this can be set in the settings? I do not find settings where thus can be set. Not in Android settings and not in the Factory Menue (PIN 126).

Thank you in advance.
[Android Head-Units] criszz:
I think is not in factory settings, just in personal settings first option i remember, but i have to look on mine tomorow.

As the canbus wires, except plug, there are also a small conector with 2 wires. On my HU i must keep deconected

Mar 31st 2021 202103310921

i'm using PX5 no DSP, have issues:

1. Bluetooth not working after update this build , this bug still alive in many recent build

2. i installed Navitel app and this app can not load the maps when lauch app using NAVI buttom
[Android Head-Units] mobi.binary:
Finally I managed to get the radio to turn on in acc key position and turn off in off key position.

The problem was that 2 cables were connected to acc detection. I had to cut one. After that it worked as it should.

Apparently the harness (by the way it was the original klyde harness) is generic so it covers as many models as possible with the problem that sometimes the pinouts don't fit 100%.

On the harness was a sticker on which 3 vehicle models were listed (Lancer/Outlander/Pajero). I have a Mitsubishi ASX.

CNS2_D_04282021_174043_V205

CPU: 64 bit 8 Core Cortex-A53 1.5 Ghz 2048MB

TDA7850

Witht this radio i got delivered an USB cable with 2 connectors, 1 for 3g / usb and the second one android phone or something like that. The problem is with music playback from an usb key, the key is scannned almost for a minute and afterwards the playback stop after 10 seconds, the song is not playing and it looks like that the radio is frozen, the SW also crashed once. Sometimes when i plug in the usb stick the screen flashes very quickly. When i unplug the usb key and switch to the radio application no sound is coming out of it, just volume up and down sounds when i try to lower the volume on the steering wheel. The only chance is to do a hard reboot of the radio. Any suggestions? Is this a SW or cable problem?

[Android Head-Units] dnfm:
Has anyone encountered slightly inaccurate GPS issues with their csn2?

Mine... Mostly works, but it seems to be consistently off by 10-20 metres.

This means navigation mostly works, but in a city where there are a lot of roads, it can get confusing when it randomly decides I'm one road over.

By comparison, I have my phone right beside the unit, and it never gets confused like the stereo does.
[Android Head-Units] _yuzo_:
I have had. There could be a few reasons:

- weak connection on SMA connector. The antenna has power 3.3V. If SMA is not tighten, antenna doesn't work.

- wrong location of antenna. Sometimes antenna falls down inside the panel and have no chance to detect GPS signal. The best place is near backview mirror.

That's not really how GPS works. It's a digital signal calculated based on known satellite positions and delay in receiving their times. Either it works or it doesn't. A weak antenna connection or poor location won't make it read off by X meters.

It's something in the software; I was hoping someone had a solution/fix/patch for it.
