Hey guys,

I have a headunit for a Honda Accord, running on Android 8, 4GB of RAM.

Here is a pic from the system information screen:

As you can see, the unit doesn't have either a MTCD or MTCE designation, it only says "CSN2_10232018_152600".

It seems to display some weird values (temperatures?) in the next line.

Googling terms like "CSN2 android" or "CSN2 headunit" didn't bring up any results.

The unit was bought from Klyde.

Does anybody know what unit this is, where does it come from, where can I find firmware for it?
[Android Head-Units] donny02:
I have exactly the same MCU Version in my new PX5 4/32 GB android device in my mazda.

The brand name of the device is ZWNAV .

I bought it directly from an aliexpress seller. And I have no idea what that MCU means :)

It works very well and I have no problems but I would like to know some more about it.

So if anyone can brighten this up, I would be happy.
[Android Head-Units] donny02:
Just wanted to give you a link to the product: https://www.aliexpress.com/item/Autostereo-Android-8-4-32G-Car-DVD-Player-GPS-navigation-For-Mazada-5-Premacy-headunit-multimedia/32913733250.html

It looks like any other mtce-device but seems to have another mcu software.

I would like to know if I could flash another rom to this device to have more control over it.
[Android Head-Units] _yuzo_:
I have the same unit. If you need a firmware, I can send you a link to my google drive (not allowed to post links on xda yet). Also this device is being simply rooted in the way as MTCD/MTCE devices.

Looks like CSN2 will replace MTCD/MTCE platform.

---------- Post added at 11:40 AM ---------- Previous post was at 11:36 AM ----------

The Chinese seller told me that it is not compatible with MTCD/MTCE and it is a completely different platform, the same was discussed on russian 4pda.ru
[Android Head-Units] NaviPR:
I need any factory firmware for this. Are the installation instructions the same as MTCD/MTCE systems?

Please send me a private message with the link.

How do you know that?

What are the differences between the platforms?

If "CSN2" denotes the platform, then how to find out who is the manufacturer?
[Android Head-Units] _yuzo_:
Done, the inastallation logic is the same as for MTCD/MTCE.

At least the seller says so...

No idea, for now. The different sellers send these devices under different brands when you purchase PX5.
[Android Head-Units] Hazard15301:
There are rumors of new units that are starting to roll out of China that have some of the Android 8.0 issues fixed, mostly dealing with bluetooth and wifi hardware issues. Maybe these are those mystery units?

What version of Android did your CNS2 unit come with?

*edit

Never mind, I didn't read.
[Android Head-Units] _yuzo_:
Android 8.0.0, Bluetooth and WiFi work well. At least my unit is OK.
[Android Head-Units] donny02:
Mine ist Android 8.0.0 too, bluetooth works perfectly and connects automatically to my android phone. WiFi ist weak as on every other device I had before. It does not connect to my home network even if it is near. I have to use a wifi repeater im my car to get it connected (xiaomi mi wifi repeater).
[Android Head-Units] aecioms:
I own this CSN2 headunit too, have it installed in my 09 Toyota Camry.

I did not like it, software is not very good.

Default ES file explorer cant send files through WLAN. I updated it to latest version, but it says "connection lost". Every file I need to use a pendrive to put it inside the unit.

LED illumination does not work well, but I belive this is a specific problem of my unit.

In settings, display size, another issue. When set to "large", icons on main screen get messed up.

Searching now for some app that adjusts volume level according to GPS speed...

My other headunit is a RK3066 4core 1GB RAM, and I use an app that makes this job fine.
[Android Head-Units] ikerg:
No. They are simply different units than mtce.

Mtce is still alive...and evolving..

Different makers are moving to their respective strategy in terms of mcu. Perhaps the mtce marked was saturated and they (klyde) are building something by their own

No. Mtce units are still mtce but with new motherboards (dsp included ....etc) but no plans to move to new mcu by the moment

[Android Head-Units] _yuzo_:
Yep, that is possible. In any case I got CSN2 unit from Aliexpress and I hope that some day it will have great custom ROMs too.
[Android Head-Units] ikerg:
I just prefer buying things that were currently well supported.

It is not easy to introduce new products and get quickly a massive market....

[Android Head-Units] _yuzo_:
To be honest, I expected to get MTCD/MTCE unit as there were no info that PX5 could be different... I've just found the one with good hardware and price. I was a bit surprised to find CSN2 there :)
[Android Head-Units] slidefriday:
My headunit though has an MTCE_CSN on it. I wonder where can i find any updates sooner :(
[Android Head-Units] RomainD2:
Just be carefull with this seller on Aliexpress (ZWNAV), no support, fake product description, IPS screen mentionned whereas it is TFT screen!
[Android Head-Units] aecioms:
Yes, you're right... Not all Chinese sellers are transparent.

I'm disappointed with my CSN2 headunit, it emits a high-frequency noise even when there is no music or radio playing...

Poor software tecnology:rolleyes:

---------- Post added at 03:35 PM ---------- Previous post was at 03:32 PM ----------

Is there any way to root or install a custom firmware?

The built in firmware has a UI that is not easy to operate. There is no apps menu, all the apps are placed on the screens to the right, and are not sorted by name...

Is it possible to make a backup of the the factory firmware ROM?

---------- Post added at 03:59 PM ---------- Previous post was at 03:35 PM ----------

I tried to change display size, but the screen became completely messy...
[Android Head-Units] meazz1:
I bought a pumpkin 8.0 which had CSN2. I returned it since I couldn't install Hal9k's ROM.

Now, I bought a Eonon unit from a seller in Hong Kong. Already installed Hal9k ROM and loving it.

The seller is superb responsive, they sent me an updated MCU file and the original stock ROM.
[Android Head-Units] aecioms:
Great!

meazz, did you try to install this custom ROM on this csn2 unit? What did you get?

could you please send me these files?

Could you please show us the main interface?

Did anyone succeed to install it?
[Android Head-Units] meazz1:
I tried but it hung, that's when I looked into the MCU and it was CSN2.
[Android Head-Units] aecioms:
Did you get to restore to the factory firmware/ROM? I'm afraid of trying to install a custom ROM and get dead unit...
[Android Head-Units] meazz1:
It hung, I power cycled and it went back to stock rom. I guess nothing was written to factory rom yet at that point.
[Android Head-Units] aecioms:
What is the seller from Hong Kong from which you bought your headunit? Could you please paste here the link to the product?

The Pumpkin unit model ND0294B-A08 I purchased from Amazon (ASIN B079N9XDFT) has a MCU version of CSN2_1122018_153527. Performing Burn In test now.
[Android Head-Units] aecioms:
Great! Please leave us your feedback!
[Android Head-Units] meazz1:
What is involved in the burn in test?
[Android Head-Units] hugoboy:
Originally, I just connected to my wifi and installed some apps. After leaving it running overnight, I found it in a boot loop the next morning. I located the current firmware from the Pumpkin support forum and flashed it back to factory default. I am now looping through a video to see how stable it is. NOTE: I'm running it off a computer PSU. Screen is decently sharp and touch screen is fairly responsive even with the protective film on it. Unable to install Google Messages from Play but does work with Hangout. Will try sideloading it later.
[Android Head-Units] sambhasanbiswas:
I just got a new head unit from Aliexpress and it is a CSN2 mcu head unit!! I have managed to get the firmware file from the seller and have it saved in my gDrive. If you want to download the file, you can visit bit.ly forward-slash csn2fw to get the Update 2019_jan.zip file. The biggest issue right now is how to get Viper4Android installed! Any help would be appreciated!
[Android Head-Units] coronero:
[MENTION=5164130]sambhasanbiswas[/MENTION], any improvements compared to previous firmwares ?

For example, does it use the native bluetooth Activity to pair devices, or still the same through a specific app only? (or maybe it's just CSN2 devices by Klyde that have this specificity?)
[Android Head-Units] adamsuail:
i agree with you, this seller sucks, he sent me a can-bus for kia sorento where as i have a sportage 2018, since am new to head units it took me over a month to figure out the reason my HU was nuts.

BTW, how do i know the type of my screen?

the HU itself is awesome, am using it with hal9k and nova launcher.
[Android Head-Units] RomainD2:
You need to remove few screw on the screen, and you can see on the PCB with the reference if it is TFT or IPS. The photo that I sent to aliexpress, but I lose the complaint...

[IMG="ZWNAV Aliexpress bad seller - TFT screen instead of IPS"]http://drive.google.com/uc?export=view&id=1e3fXnvv-MJHQeB9NF9gGxOidOhbIsQKN[/IMG]

Where did you find hal9k builds for CSN2 MCU? Are there privately shared builds roaming in the wild ? :fingers-crossed:

Pros and cons of CSN2 headunits

[MENTION=4381316]coronero[/MENTION] the update changed nothing but helped me get rid of the bloatware the seller supplied. Post update i have installed Car launcher Agama.

Am using the headunit for over a week now and here are the few pros and cons I have observed:

Cons:

1. Bluetooth not available in settings, so cannot use Agama's Bluetooth widget

2. Bluetooth player, Radio, music player etc are same application with different activities. So neither Agama luncher nor tasker can properly figure out where am using Bluetooth player or am using Radio

3. Unable to change boot logo/ boot animation

Pros:

1. Voice control is available by default

2. Google voice control can place calls using the Bluetooth app provided

3. Can choose never to shutdown the headunit when when ACC is off
[Android Head-Units] aecioms:
Another cons: in my unit, the HU cannot mute the volume when there is nothing playing. I perceived a low noise coming out from the speakers, just like a radio station badly tunned. This is annoying... To stop that, I have to turn mute ON. When I want to listen to anything (music, radio, BT), I have to unmute de HU...

I'm disappointed ith this CSN2...

---------- Post added at 03:00 AM ---------- Previous post was at 02:57 AM ----------

I got to install a new Klyde launcher in my CSN2 headunit. Now it is easier to find apps (they are sorted by name now, not by install date anymore). Vey good. In my opinion, it seems to be better than the oyther lauchers customizers out there.

The only thing I miss is the wigded on the main screen, the new launcher I installed does not figure out when the HU is playing audio...
[Android Head-Units] coronero:
Cons:

1. Same thing in the November firmware - it looks like it's implemented in a side-app, overriding the system screens (which are broken/blocked if you somehow manage to launch the corresponding screens). So no change here, IMHO.

2. That's a bugger, but ok. It's like that.

3. Factory settings with code 888 doesn't work anymore ? :eek:

Pros:

1. 2. - good news :)

3. Already had that option somewhere. But it's kind of buggy.

The device is having trouble coming from standby. The screen remains black, and I have to restart the car to force restart the device. Btw, if FM radio was playing on the day before, it's playing audio only with the black screen. :(

---------- Post added at 11:31 ---------- Previous post was at 11:28 ----------

Did you side-load the new launcher, or did it come with the new firmware update?
[Android Head-Units] aecioms:
As factory settings code, I use 126 and it works fine. But there is no way to change boot logo, unfortunately. I think my HD is from Klyde, they usually use this number as factory settings code.

---------- Post added at 12:16 PM ---------- Previous post was at 12:13 PM ----------

I just installed the launcher from my other car's HU. The default launcher is called launcher3.apk.

The on I installed is launcher.apk

Until now I did no firmware update (By the way, how do I do that? Do I have to contact the seller?)
[Android Head-Units] warata:
I also got CSN2 coincidentally (I thought this was an MTCE).

This product can operate recovery with touch screen.

Can't detect GLONASS same issue as MTCE-PX5 Oreo.

10.1" IPS (maybe fake) PX5 4+64GB

Bought from skyshadow aliexpress

https://www.aliexpress.com/item//32891758260.html

How to set that never to shutdown the headunit?

Thanks
[Android Head-Units] coronero:
Same here, 126 to access factory settings (canbus, amp volume gains etc.) and 888 to access the boot animation override. ;)

---------- Post added at 15:43 ---------- Previous post was at 14:46 ----------

It's somewhere under the System settings / Car settings ... not even in the Factory settings, but really in the open. I'll take a screenshot when I'm in my car.
[Android Head-Units] aecioms:
Settings, car settings, personal settings
[Android Head-Units] warata:
Thanks but still I can't see that never to shutdown.:(
[Android Head-Units] coronero:
:laugh: its Chineglish, but the option is right there. Power off delay when ACC OFF means in what time after having turned off the car engine should the HU be Shutdown. In your case it's off, meaning standby at all times.
[Android Head-Units] warata:
Thanks for pointing out.:)

Then there is nothing new change.

This menu also existed in MTCE, and changing the value does not affect the operation of the head unit.
[Android Head-Units] warata:
Auto dimming

Anyone could succeed auto dimming with this CSN2 headunit?

I found a panel led menu in the factory settings but this doesn't work.

Thanks
[Android Head-Units] aecioms:
I saw this too, but dont know how it works exactly.

I didnt even understand what "switch control means". I set my HU to illumination control (headlihts on, HU screen becomes darker)

Unknowingly bought this to replace faulty MTCD/E unit

Hi,

I have just received this after trying to replace my faulty MTCD/E unit. Thinking it was the exactly the same, I tried to install Hal9k rom. Now it is stuck on the Pumpkin boot screen. I think the Hal9k Modinstaller.apk replaced the recovery and now it wont boot into android or recovery to do a full reset or restore to stock.

Can anyone suggest what to try next?

The stock launcher is a little different.

And now i can edit the volume levels of everything in the car settings. otherwise everything is still the same.

I think ill reinstall the old version and rip the launcher then reinstall this one and add the old launcher to it.

Can you explain how you connected the headunit to PC, step#2 and #3?

Do I use a laptop with USB connection?
[Android Head-Units] KidGixxer:
Log into your wifi network on your radio in your car.

once its connected and assigned an IP number write it down.

On your pc when you do steps 1-3 copy and paste word for word.

When you get to step 4 change the two lines that say "# adb connect "device_ip""

Where it says "Device_ip" put the ip number you wrote down.

It should look something like this.

# adb connect "192.168.1.1"
[Android Head-Units] warata:
#2 On your PC, download latest "SuperSu" zip archive from official site,

I think it is impossible to download the supersu.zip from an official site now.

But you can find it from other place. I want you to exploit with google.

Also this movie will help you.

[Android Head-Units] meazz1:
I got the download part but not sure if I connect using a USB.
[Android Head-Units] KidGixxer:
You do not need to connect your pc/laptop to the radio.

Once you connect to your local wifi network that your pc/laptop is connected to, you will be able to connect to the radio over adb and send the commands.
[Android Head-Units] meazz1:
Ok, got it.
[Android Head-Units] KidGixxer:
Quick question for anyone else that rooted. Is root checker verifying root for you?

If i install the binaries for SuperSU, root check confirms root But the radio soft bricks on reboot.

If i do not install the binaries root checker does not verify root.

Either way, The toast notifications from SuperSU say it is granting root permissions.

I just want to confirm with other on this.

And in case anyone was wondering.

[Android Head-Units] sambhasanbiswas:
Rooted my headunit yesterday. It was butter smooth. You can even find the video posted earlier for reference.

I have rebooted the unit quite a few number of times and there is no issue. I have only used the 'su' file from super user zip as mentioned in the instructions. Every time superUser starts after reboot it requests for updating the binaries but I never did so, still root checker confirms that my device is rooted. I have also activated and used the root explorer with no issue at all.

Warning:

Use command prompt (cmd) and NOT PowerShell

[Android Head-Units] sambhasanbiswas:
Nopes, never had such problems but earlier a similar incident happened and the problem was with the launcher (car launcher agama). I realised it because after few minutes when the pop up message appeared with an error message that 'car launcher agama' stopped working.

You can try the following:

1 switch to another launcher

2 change settings such that your device shuts down after an hour or so (because sometimes apps refuses to load after very long sleep)

3 reset the device
[Android Head-Units] warata:
Yeah, It is true. I always watching YouTube while I driving. Resume can be played after several hours sleep, but next day resume playback is impossible.

I had this problem with the early January firmware, and was using FCC Launcher at the time. Same issue, won't turn on screen after an idle night.

With the late January firmware have never experienced this issue, nit even once, and btw ive switched to Agama. IMHO it's definitely not a launcher issue, but a firmware bug.
