Hello,

i have a heavy problem with this unit type..

i have installed it in an hyundai i20 from 2018.

After installation the unit funtions normally for a week.

Then following problem occurs:

The unit does not start...

i have to put out the key und put in the key several times, then unit start again...

To solve this problem for a while, i have to disconnect the car battery then unit functions and start without a problem for a week or so and then the problem occurs again...

i have installed latest mcu and android 9 firmware from here....

I have also contacted chinese seller and they have no solution...

Can anybody help here ???

Hey yuzo,

Any ideas on how we could get custom firmware? Would it just be a vanilla install of Android? I definitely do not want to blow away all the work being done but if there's a custom approach or a sideload that would be awesome. Just picking your brain a bit. If we could get viper running somehow in your code, you would be a freaking hero!
[Android Head-Units] _yuzo_:
Android part is for all units.

Either a hardware problem or unstable wiring. Try to test the unit on the table.
[Android Head-Units] _yuzo_:
That is not my code :) I'm just have a contact with Klyde factory. They share a new firmware, but keep the specifications in a secret, so only a reverse engineering can work there. I'm not powerful in that.

Updated the first post of the thread with Mar 7th 2020 firmware, no changelog from factory so far.

Overlapping Symbols Parking Assistant

Hello,

i have a Problem with my new Klyde Android 9.0 Car System.

Whenever the car detects an obstacle, the symbols marked in the attachment appear. Unfortunately, these no longer go away and overlap the desktop icons. Only when use reset the Icon goes away.

When I click on the P symbol, only the car symbol disappears - the P symbol then remains on top and does not go away.

I would be very grateful for any help.

My system:

Nissan Quashqai with 360 degree camera

Klyde 64/4 Android 9.0 system

Build number: 202003071131

MCU version: CSN2_D_12282019_111900
[Android Head-Units] SKORPiO1975:
I have been fighting this for past 2 years. No way to remove the P icon.
[Android Head-Units] liamstears:
If you have a rooted device I can easily send a modified APK to completely disable this icon...
[Android Head-Units] SKORPiO1975:
Thank you for reply. I can root it without problems. Can you post the app here or should I DM you?
[Android Head-Units] liamstears:
Ok I have attached it to this post

The APK attached will remove the icon completely and it will not be usable at all

The apk attached is from the latest March 7th update, it may work on other versions but it is designed purely for this rom

If there are rom updates I am happy to make a new apk if needed please just PM me

apk needs to be placed in: system/priv-app/MyCarService replacing the original APK, root is required and please make sure you correct the permissions
[Android Head-Units] SKORPiO1975:
Thank you for that.

I have an android 8 on mine. I think I'll pull my apk and ask you to modify it. I remember I updated another apk on my unit a while back and it wouldn't boot anymore. I had to flash stock to recover from soft brick.

Hi. I have one pumpkin 8 inch android 9 with built number: 201906111729 mcu: csn2_05312019_173534. I can update mcu and firmware with firmware and mcu posted on first page? What is the last mcu and firmware? Tnx in advance
[Android Head-Units] rigattoni:
Why don´t you guys just read the first posting in this thread? There are all needed information laying around.
[Android Head-Units] vince360:
sorry i have read all the first post and i think i get the right one but for safety i ask first. i don't want brick my unit O.O

update: i flash the last mcu and firmware and all work fine!the restart is much faster. now i just think: if i root the device, no viper4android on csn2 unit right? and no custom rom or recovery for now, right? tnx in advance guys
[Android Head-Units] rigattoni:
None of them, but i don´t miss any of these tools.

I have rooted the device for having some improvements with Tasker, but that´s all I need for now.

To be honest, I never use a custom ROM, I am not a friend of these custom ones.

hello guys i have an erisin es7723l car radio, i am using it with amplifiers but the radio always has an annoying background rustle (it was not there with the old 1Din Pioneer that I had before) does it also for you?

P.S. I have already tried the latest updates available on this page but nothing has changed apart from the interface ...
[Android Head-Units] T00bN00b:
I had a similar problem and fixed it by installing a ground-loop-isolator.
[Android Head-Units] _yuzo_:
Added Mar 27th firmware for everyone and Mar 19th MCU for DSP units.
[Android Head-Units] Ioaldo91:
I have one (it's not branded and I think it's not even good) but if I mount it the problem gets worse ... you could tell me which model you are using and if you mounted it on the amplifier input or on the radio output
[Android Head-Units] Kimo2014:
Any issues / bugs in this firmware?

This my HU
[Android Head-Units] T00bN00b:
I have no idea because a friend of mine installed the radio and amplifier for me. But he told me that he needed an ground-loop-isolator because of the now occuring rustling sounds.

My radio is from Pumpkin and without DSP

Seems like they removed all the bloatware (ES File Explorer, etc) from the firmware.

After updating the unit skipped the part where those apps normaly used to be installed right after first boot.
[Android Head-Units] Ioaldo91:
i just installed the latest firmware and reinstalled all the apps .. esfilexplorer etc ...

let's see if it brings any improvements to the audio

New fixed MyCarService.apk for Nissan 360 ° Camera (remove p symbol) for Mar 27th firmware.
[Android Head-Units] vince360:
hi. i have updated my csn2 HU without DSP to the latest firmware and mcu posted on the first page. all work great but i can hear some buzz noise while playing music on spotify or poweramp. expecially for example when the track change and for some second no sound is playing i can hear the noise. radio seems to be not affected. anyone know how to fix this? and with the old mcu i have 2 volume on spotify and poweramp. 1 master volume and the volume of the head unit and when i restart the unit i need to put it all the time from 73% to 100% on poweramp or spotify. i hope the new firmware or mcu fix it but the problem is still there and if i put the volume up to 100% nothing change now... if someone can help... sorry for my bad english

p.s. and i have not an amp

[Android Head-Units] Kimo2014:
Good news, so What's the new in this version plz?
[Android Head-Units] _yuzo_:
Added April 10th firmware.

Factory does not provide a changelog. I did not notice any visible changes. Most probably bug fixing only.
[Android Head-Units] Azumi4:
in this firmware "March 27th 202003271050 + MCU CSN2_D_03192020_105411" they finally added the outside temperature information to the status bar

my car: chevrolet Malibu 2014 LTZ

every time I was updating as soon as you post a new firmware hoping I get this feature, and now finally I got it, because it was on the old OEM stereo screen and I really miss it.

thanks :)

and now I'm afraid to update to 10th April firmware and lose it:laugh:

Has anyone tried to upgrade the PX5 CSN2 without DSP unit from ANDROID 8 to 9 without taking out the unit? I am thinking of doing it and want to know the experience you had. I will appreciate if you reply with any comments or suggestions.
[Android Head-Units] philicibine:
Straight forward AF so long as you RTFM. ??
[Android Head-Units] FullSky:
hi at all.

i have a question: i would to upgrade my navigator with a new MCU.

I have a PX5, MCU version is: CSN2_11112019_114851 can i upgrade it? With what version?

And then, can i add the last firmware of april?
[Android Head-Units] _yuzo_:
viper4android does not work without magisk modules. There were no successful attempts to make it operable on our unit.

However, Sirenes audio has been tested by 2 users on 4pda. And they say that it really works.

[MENTION=4381316]coronero[/MENTION] is one of them.
[Android Head-Units] sambhasanbiswas:
Can you please translate the installation guide for us? Does it support ‘English’ interface after installation?

Thanks :good:
[Android Head-Units] MansonDroid:
Has anyone successfully paired the OBDLink LX to this model? I've tried the tricks with the password people have suggested, but it never connects. I've tried Graser's Dasaita Tool, but it freezes the unit.
[Android Head-Units] _yuzo_:
Graser's Dasaita Tool will not be working at least until we have Xposed ported for our unit. Is OBDLink LX OK with MTCD/MTCE units?
[Android Head-Units] MansonDroid:
I've seen some people report that they got it to work in a few threads. Not sure if they were using the tool or not.

I installed Xposed through the official installer apk, and it seems to be working. Haven't tried any modules other than Graser's though.

Also, if I may, I'd suggest not updating the SU binary or the SuperSU app. Both caused a boot loop.
[Android Head-Units] _yuzo_:
That was written in the very first post using red bold font long time ago.:) But seems like that notice is still ignored:D
[Android Head-Units] MansonDroid:
Just the way it is worded makes it seem like only the app itself shouldn't be updated lol. Not the binary as well. Just a miscommunication. No worries
[Android Head-Units] _yuzo_:
English is not my native, but anyway, I'll update wording tomorrow (not convenient to do that using the mobile), to have the text more accurate.
[Android Head-Units] MansonDroid:
Either way I appreciate your work! Thank you.
[Android Head-Units] coronero:
I've tried multiple times, with both Klyde and Pumpkin firmwares, with no success. It sees the OBDLink LX when searching but pairing fails, with no error message. :(
[Android Head-Units] MansonDroid:
Yeah, that was my experience. I don't believe it's a whitelist based on name, as I changed my Pixel 3 name to match the OBDLink, and it pairs fine. Might have something to do with it being Bt4.0 and communicating differently than it expects, like some people have mentioned on the MCTD threads. I'm not really familiar with how Bluetooth transmits though.
[Android Head-Units] sambhasanbiswas:
[MENTION=4381316]coronero[/MENTION] nice to see you here. Recently I learnt that you have tried installing 'Sirenes Audio' mod. Is there any improvement in audio quality? It would be great if you can throw some light on the audio mod
[Android Head-Units] GDFI:
What does MCU CSN2 mean? Is there a way to know if it applies to this https://s.click.aliexpress.com/e/bDomzaz2?
[Android Head-Units] _yuzo_:
Most probably that is CSN2 as well as our devices. But please ask the seller to show the hardware specifications in the system settings.

MCU (see wiki ) helps to connect android tablet with radio module, BT module and amplifier, other car components etc., so we'll get a head unit:)
[Android Head-Units] coronero:
Hello to you too ?

Actually with Sirenes it's a hit or miss. Sometimes it works and the sound is fuller and nicer to the ear, other times it doesn't look like it's active at all.

It doesn't break anything, but because it is not a very consistent experience, I would not really recommend it. I've had better results with PowerAmp's preamp and tunings than wiith Sirenes.
[Android Head-Units] sambhasanbiswas:
I mostly play music from regional online music players like gaana, amazon prime music. Can Poweramp's preamp anyway enhance sound quality from such players?
[Android Head-Units] coronero:
Nope, PowerAmp is just a player lije any other. It can't apply DSP on system-wide level tre Viper4Android would.
[Android Head-Units] sambhasanbiswas:
Exactly... Am looking for something similar to viper4android. Is there any scope of getting it in near future?
[Android Head-Units] dorkisbored:
Is it possible not to close certain apps when the radio goes into standby? Like Deezer or Spotify?
[Android Head-Units] monstermuffin20:
Just upgrade it to the latest version on the first post of this thread, I got a new HU days ago and did just that.
[Android Head-Units] FullSky:
thanks, but what is it your new HU?
[Android Head-Units] _yuzo_:
Added Apr 22nd and 28th firmware. No changelog so far.
[Android Head-Units] FullSky:
Sorry if I ask another question.

I saw on the first page that the latest MCU for Android 9 is the CSN2_10112019_145049 version while the one I installed is the CSN2_11112019_114851 version. How can I understand which is the most updated one?
[Android Head-Units] _yuzo_:
Seems like yours is the most recent. I have only CSN2_10112019_145049 for units without DSP. Will try to contact the factory.
[Android Head-Units] Keiuran:
I recently started playing with this thing again and I've run into a few issues. First issue is my microphone (the built-in one) started sounding like crap all of a sudden. Using a mic test app I sound very distant, echoy, and almost drowned out, I think there's some grounding problem with it internally.

I tried connecting an external mic but I have more experimenting to do in regards to that to maybe make it work. The connector on the back of my unit has 2 USBs and a mic input next to those inputs. See photo.

Secondly, I cannot get the headunit to turn on the back camera when I go into reverse.. It was just recently installed because it was a lot of work to install the camera properly and I put it off initially when I first installed the head unit. I can open the F-Camera app and select the back camera and get video from the back camera only when I'm in reverse, but I can't get it to automatically open the F-Camera automatically and I have no idea what the problem. I'm sure there's some setting somewhere that I'm missing, but I've played around with what feels like all of them, even in the factory settings menu, and I haven't found a solution. Any help would be appreciated.
[Android Head-Units] behnammodern:
about your first problem if you are familiar with soldering, the best way is to solder external microphone directly to internal microphone , thats the only way you can have a great microphone otherwise dont expect anything

about your second problem you must find out the REVERSE wire of your car and connect it to orange with black line wire of the unite, that way you can trigger the back camera

---------- Post added at 06:31 PM ---------- Previous post was at 06:30 PM ----------

finally last update you can study canbus key

I did it on MAZDA
[Android Head-Units] SKORPiO1975:
Do I desolder internal mic and replace it with external, or do I leave internal mic in and just add external?
[Android Head-Units] lew26:
Why not just connect an external mic to the cable which also had the 2 USB Jack's? On my HU connecting the external mic automatically disabled the internal microphone
[Android Head-Units] Keiuran:
1) Could you clarify a bit more in regards to soldering the external microphone? Why can't you use the external connection for microphone?

2) Was that wiring not automatically taken care of by the harness? Which wire is the reverse wire in the car? Is it the same reverse wire I powered the camera with? I have a 2014 Mazda 3 klyde unit. I looked at the wiring and the orange/black wire is connected to the cambus so this sounds like a software issue.

3) You can study the canbus key? What does this mean? Is there a way to make the steering wheel buttons (Bluetooth, Call, and Hang Up) that don't work actually function? I found the wire they're connected to but I don't know how to wire it into the headunit to work. There's a KEY1 and KEY2 wire that are just floating on the unit not doing anything, but the other switches are handled by the cambus (Volume Up/Down and Seek Left/Right).

I just succeeded in connecting my car's microphone that already sits in the overhead lights. The internal microphone was no longer indicating it was hearing my speech. My only issue is now is that there's a massive amount of noise in the mic. People can hear me when I speak, but there's a ton a static, even more so when just using the internal. I find it hard to believe it's a problem between the mic and unit as I'm using the existing wiring harness to pass that signal through. I believe there is something wrong with the internal hardware of my unit that is causing this noise so I will need to investigate.
[Android Head-Units] timknowlden:
also following this for microphone info, I have a pumpkin unit - AA0495B and the internal microphone is terrible, I have de-soldered it and using external microphone using the USB/Mic loom but it is also terrible, I have looked at this thread: https://xdaforums.com/showthread.php?t=3246277

however the circuit board on this unit is completely different.

This isnt the case with my unit, the only way to disable the internal mic was to desolder it from the PCB, but the external micrphone still picks up an awful amount of noise.
[Android Head-Units] behnammodern:
1.cut the external mic wire and solder it directly into internal microphone , no need to de solder , you can just solder it on the existing internal mic

2.if you have Mazda then no need REVERSE WIRE , the device will automatically knows you are in R gear

3.yes , update to the latest mcu and software , then go to SETTINGS/FACTORY SETTINGS/126/KEY/CANBUS KEY STUDY , then you can study each button on steering wheel,your car dont know KEY1 KEY2 , this is new thing you can study canbus keys
[Android Head-Units] Keiuran:
1) My existing internal mic started having problems which is why I tried to connect an external microphone, but the noise is just as bad, if not worse.

2) My unit is not detecting my car going in reverse though. Could you take pictures of your settings in 126? I might not have the proper settings so my headunit isn't properly detecting me going in reverse.

3) The buttons that don't work on my steering wheel are not connected to the canbus. Only the Volume and Seek buttons are connected to canbus. The Call, Answer, and Hang up buttons are tied to a different connection that went through a separate bluetooth module on the passenger side of the car. I've located that wire and attached it the headunit at KEY1 but that didn't work. Will try KEY2 after I do some more soldering to fix mic.

Hello Yuzo

Can yo share the latest Fm Radio apk pls.

Thanks
[Android Head-Units] _yuzo_:
Radio, as well as Music, is a part of CarUI.apk. Should I extract that for you?
[Android Head-Units] timknowlden:
Have you measured for 12v at the camera signal cable where it connects to the head unit?

You need 12v there when the car is in reverse.

If you have 12v make sure there is then a good connection between that cable and the reversing wire of the head units loom.

I have awful sound on the microphone and can’t see how soldering to the front panel is going to help.
[Android Head-Units] umiteks:
So no need.

Thank you...

Actually I wish a more customizable Radio apk!

BTW, how can we check the differences/what changes in each firmware update...
[Android Head-Units] Keiuran:
I have cambus, this shouldn't be necessary.
[Android Head-Units] timknowlden:
Ah okay, I dont know enough about canbus. Have you tried to give it 12v off anywhere just to prove the unit switches to camera anyway ? Or perhaps just connect it to the reverse light as a workaround?

Surely someone will know a way to improve the microphone on this unit also....
[Android Head-Units] _yuzo_:
I've been writing about that constantly... The factory does not provide us with changelog.:(
[Android Head-Units] behnammodern:
I think you have a wrong car in canbus settings

go to factory settings/126/canbus/

and then choose other mazdas , I think we have 3 diffrent mazda on canbus list

[Android Head-Units] _yuzo_:
How do you know?
[Android Head-Units] umiteks:
Sorry friend I missed that...

So do you thing will it worth to try upgrading frpm October to April (I saw you were talking about May release somewhere but couldn't find)

Or is it better to wait or 10?
[Android Head-Units] _yuzo_:
There is no May firmware as May 6th the first working day for factory in May :) April 28th is the most recent.

If you're good with October one, have no bugs/troubles, live with it. If there's something annoying for you, go ahead with upgrade. Note, that /data is formed during the upgrade.

I know nothing about android 10 and plans for it.
[Android Head-Units] Keiuran:
I have Mazda 3 (Simple) picked. It works with my buttons except I have to reverse the seek buttons, but it does work. I could try other mazdas to see what happens though. Also update cambus firmware. I'm not on the latest.

Hi there,

is there a way to disable the floating "DISP" Button in latest Android 8 ROM?

As I own a Qashqai with 360° Camera, I don't need this button.

Further questions: Has anyone successfully attached the cars DAB Antenna to a USB DAB Dongle?

I tried it on different ways but the dongle doesn't find any channels. If I attach an external antenna, the dongle works fluently.

I don't want to add an extra antenna as the Qashqai already has one.

And is there a way to define for example an App that is shown on the external monitors?

I got 2 headrest monitors connected to the Headunit so for example the passengers in the back can enjoy a movie while I can navigate in the front or listen to music.

Thanks!
