Finally I cancel canbus from Kia factory amplifier and convert RCA TO SPDIF I get tired from canbus box with my head unit today I finished working on it and I’ll tested in my car to find out if there any problem but it’s looking right now great with good sound all this Cost me around 12 $ only ,but this method need electronic experience to do it ,by the way I’ll Share how I did it ,I don’t know it will work with all factory amplifier or not let’s see
[Android Head-Units] blackdiamont:
I've tried Upgrade via Recovery, hope this helps:
[Android Head-Units] abdelmonem:
If you want to upgrade to android 10 you have to open your HU ,and flow description in this post up , in my case I did it like this attach picture

Also if you get problem with windows 10 try to switch to windows 7 and don’t use usb 3 I try it not working but usb 2.0 it’s okay

before all of that check your board version , and Be careful if you will use this method
[Android Head-Units] blackdiamont:
thx! I'll try if I have some time.

So without disassembling the unit I'm stuck with Android 8?
[Android Head-Units] abdelmonem:
Yes, that's right by no means not difficult if you have experience

Also when you solder the usb into your HU board you have to unplug the original usb from your HU so you don't lose the usb power it's happening with me and i don't know why

but if you have usb attach in board or short usb cable try to use A to A usb cable type

good news i switch from BT MD-705 to RF 210 i order from ali express also FC6000TN but good think the seller told me it will not work :) he don't know about

switching from md-705 to RF 210, look at the picture below without problems, just for info, different printing on the board doesn't mean all BTs are using the same protocol when switching in factory setting, that will reconfigure all bin

just one additional connector i made it my self to remove BT module easy in future

now i get internet via BT back :)

solve problem with original mic

The original circuit has a resistance of up to 7.9 mega ohms

When the mic is connected and the circuit is canceled, the impedance is reduced to 1.9 mega ohms

The car is Kia, it may differ from other types of cars, make sure by measuring the circuit before you modify

[Android Head-Units] abdelmonem:
The link for the most recent firmware and MCU: with DSP and without DSP. _D_ in the MCU version means that it is for units with DSP.

Hi everyone! Seems like a new maintainer is required for this thread :) I've been using Klyde for last 2.5 years. Now the unit is sold to a new owner and I have UIS7862 in my car. Klyde is great and someday I'll be back. I'm going to unsubscribe from this thread, but still can help if you write me a private message. :)
[Android Head-Units] T5rider:
Thanks Yuzo for your kind help for all these years
[Android Head-Units] T5rider:
Good day to all,

1st I understand Yuzo is leaving. Thanks for the help during all these years!

2nd I have a video issue on my CSN2 PX5: back camera has suddenly stopped working without any action from my side... Was working OK, connected only to the video in + dedicated single power cable (running along the video cable) onto the head unit. Back video was appearing as expected when engaging rear gear.

Now nothing happens any more. Suspecting the camera or wiring, I plugged a new cam directly into the video in, powered it up with the power cable (which I have checked to deliver 12V). Also tried alternative 12V power sources from the back of the unit connected to the two power cables of the cam. No success. The screen does not change to rear cam view (not even the black screen / warning triangle). Tried the forward cam port using the dedicated app, nothing happens as well (only black screen + warning triangle).

The car is a VW T5, I am using a CANBUS. I was suspecting this not to give the correct info when engaging rear gear, but I now doubt because I should have been able to get the forward cam working.

Anyone having an idea? Thanks in advance

Hello all, I updated my CSN2 PX6 Unit (Android 10) to the latest firmware (202103311813) and MCU. I had the wrong resolution and had to change it with the OEM folder on the USB stick. Now I have the issue that the integrated LTE modem (onboard, no USB stick) is no longer functioning. The mobile network setting in the settings is grayed out. Do I have to enable the modem somewhere?

Hello everyone.

I have recently purchased a Fiat Punto evo with this sytem installed

Specs:

MCU: CSN2_12272019_115005

Build: 202002291450

PX5

Android 9

My main issue is microphone quality.

So prev. owner only used the internal mic, i added the external mic and quality is still ****, also i think they are both working together (i used a sound recorder app to test).

Is there a common fix to this issue? i'm gonna try and update fw and mcu to latest android 9 (i have read a lot of this thread and 4da as well before posting).

excuse me a question: but if I mount the external microphone it doesn't work for me? do i have to make the change you made?

thanks
[Android Head-Units] gassnico:
Hi fullsky,

the desoldering wick was needed to compensate the hole size of female jack connector that generated wrong contact and motor noise in audio.

did you try to move jack connector during recording test to check if it's a bad contact or not ?
[Android Head-Units] FullSky:
no, I still have not connected the external microphone .... as soon as I do, I tell you.

Thanks.

hello is there a new update of android 10?
[Android Head-Units] daemondee:
I have CSN2 without DSP. The latest version of the MCU, that back camera works with, is this CSN2_0122019_102034. If I use the newer ones from 2020, the camera doesn’t work (shows "no signal").

However, I would very much like to have the latest version CSN2_10132020_181154 because this is the only version where the radio stays on when I turn the ignition on. In older versions, it always turn off and boot from the beginning.

Why back camera doesn't work in newer versions? Is there anyone with the same problem?

Hi, you've to do the steps described in one of the first threads. It's not possible to update using SD only. I did it the described way and everything worked well
[Android Head-Units] :
I bought a belsee for my 2021 Mercedes sprinter, problems from the start. After trying so many different things with the wires and changing settings for the canbus the seller is sending a new canbus unit/box.

I was able to buy a harness from mid city engeniring to fix the sos light on the dash, I was able to hook te illumination wite to get the stereo buttons to light up, a harness for the backup camera and a wire to the fuses for the stereo to turn off when the engine is shut off and the doors open.

The problem that I was not able to fix was the rear camera, sometimes it would turn on when pit in reverse and most of the time it would not come on on the head unit. (I have the reverse trigger wire connected to the camera harness and the stereo.

I reset the stereo to make sure it was not a setting that I had changed, but now I lost the agama launcher that came with the stereo and the reverse camera does not work anymore and I think a bunch of apps that came with the stereo are gone.

The version of Android that I have is newer than what's in here so I don't know what to do, I have contacted the seller but it takes to long for them to answer,

What can I do to get the back up camera on the head unit?
[Android Head-Units] lew26:
Intermittent issue suggests trigger wire might not have a good connection. Check your solder connection. Re crimp with a new cap
[Android Head-Units] :
Thanks will try that, is there a newer firmware or mcu update newer that what I have on my radio? And if there is which ones do I choose 🤔. TIA
[Android Head-Units] lew26:
I would have stuck with whatever came with your unit. Update if the new version solves an issue or your unit has been stable for weeks

You won't know if an issue is with your unit or with the new firmware

Getting dealer support might not be easy if you modified firmware. Let your dealer give you necessary firmware updates

I have 2 questions please.

1 Is it android 10 or not?

2 The GPS signal is very unstable. What is the cause? Antenna, hard, soft? Have you ever encountered something like this?

Thanks.
[Android Head-Units] _yuzo_:
1. Yes, android 10

2.Yes, I had. Most probably, a weak connection on SMA. Antenna should have 3.3v without any interruption. Just thighten the SMA nut. Also it would be more stable if the antenna is placed on the windshield.
[Android Head-Units] albundy0064:
Hi!

Thanks for the reply. I had another media model. The signal was much, much better. The position is the same as the old one. I also suspected a hard problem ... SMA of dubious quality, the length of the connector wire is a bit large and the shield is probably of poor quality ... Anyway ... thanks for the help. It's good. Keep in touch.

[Android Head-Units] _luke!_:
Hi,

I'm using Android 9 on CSN2 and flashed the last PX5 firmware and MCU.

With this firmware and also with the stock firmware I have a bad background noise on my speakers. Just when I turn the volume to 0, the background noise disappears. What I read, the sound quality on PX5 is not good, so I tried to use a USB-Soundcard.

When I plug in the soundcard, I see in dmesg that the soundcard is recognized and the driver is loaded. But no sound over the USB-Soundcard. The reason is, the snd-usb-audio module is not included in the firmware. The kernel is built without this module.

So anybody has a solution for the USB-Soundcard problem? Is this module available anywhere? Or is the kernel for the firmware available, then I could build the module for my own.

Thanks

Hello All!

I have a Klyde KD-1753 PX5 Android HU that I purchased from AliExpress for my 2014 Volvo S60 T5. I have been going back and forth with the seller, and I have had to fix most problems myself. After sending me the wrong wiring, and then the wrong CANBus, most things are working the way they should.

My biggest problem, is that the steering wheel functions do not work. I have attached pics with my settings. I tried going into factory settings to see if that was the problem, and that fixed my issue with the climate control not showing by changing the CANBUS to ODIE Volvo XC90. The problem here is that there is no manufacturer that has VOLVO S60. I'm not sure if this is the problem, or it is something else. Any help would be greatly appreciated!
