Hi! If I run Waze without a route, the pointer moves smoothly, as if filtered. If I run Google maps, the pointer does jump discretely, as if it represents the unfiltered update rate of the GPS. It’s more like 1 time per second on my system though, not the 2-3 seconds you mention.

I have tested the system now a bit longer and some more buggy-ness and instability is surfacing now. Waze worked well for the first few days, but at the moment I cannot use it, as it crashes, seemingly as soon as directions are being given. Tried restarting and closing apps, but no joy so far.

Also I am unable to have the Twilight app (which I want to use for automatic screen brightness adjustment during night drives) consistently functioning after reboot or stand-by mode. Somehow the permission I gave it as Accessibility Service automatically gets disabled over time... not sure whether it’s me not understanding the Android system and settings well enough yet, some other Apps that are intervening, or the Isudar Android install that is just buggy.
[MTCD Android Head Units General] Bettman66:
Thanks, I'll test WAZE and see if it runs smoothly. I haven't noticed any crashes or instabilities, except for waking up after deep sleep.
[MTCD Android Head Units General] Bettman66:
I also tested the Twilight app and it works without any problems. WAZE runs smoothly as they said. I am very satisfied with the device. No other errors have appeared so far.

I switched to the new image from the Isudar website.
[MTCD Android Head Units General] Darius22574:
This is a direct link to google drive but where exactly can you find the update files on isudar website?
[MTCD Android Head Units General] Bettman66:
Isudar
[MTCD Android Head Units General] Darius22574:
After the update I no longer have day/night mode...
[MTCD Android Head Units General] Bettman66:
The day / night changeover is controlled by the Canbus. When I turn on the lights on the car, the screen gets darker and the switch lights come on. This is not done via the Android firmware, but via the MCU. It may be that the settings in the factory mode for the Canbus are not correct.

My car is a VW Touran.
[MTCD Android Head Units General] Darius22574:
My car is a VW Golf VI but after this update when I turn on the lights nothing happens and I tried to change the settings in the factory mode but no luck :(
[MTCD Android Head Units General] Bettman66:
There is also a brightness adjust in the factory setting for "other" because the "automatic brightness" can be switched on / off.

This has nothing to do with the firmware, the day / night switching works for me when the head unit is started up, Android is not yet loaded.

Changing the original launcher from light / dark doesn't work for me either. I use the CarLauncherPro and the light / dark of the backlight.
[MTCD Android Head Units General] Bettman66:
I think I found the setting for DAY / NIGHT in the HCT7 Launcher that you mean.

In the new update it is not available. I flashed an HCT7 image from 04/15/20 and there the option can be selected.
[MTCD Android Head Units General] Darius22574:
Sorry if I keep bothering you but where did you find that image? And what I mean by day/night mode is dark mode on the launcher and settings when I switch on the lights.

[MTCD Android Head Units General] Bettman66:
The image is from here. I flashed it via the SD card method using sddisktool. An Ota update from the site didn't work. If you are not sure about flashing an image, write to the hotline on the Isudar site to get a working OTA update.

I have recently purchased and fitted the same car radio for nissan qashqai. Do you also encounter problems with GPS when using maps? Do you have solutions? Or should we change Rom?

[MTCD Android Head Units General] Bettman66:
There are no GPS problems during the routing, only the pointer jumps every second without it.

I now have the OTA update A10 AV8V6 from M.I.C. flashed. This works without any problems and switching with the light switch is also possible. But the launcher is not the same, I don't know if you like it.
[MTCD Android Head Units General] Darius22574:
I talked with ISUDAR support and they gave me this ota https://mega.nz/file/ulEi0LhI#agaxU64gKJ9BJzWLEXgPLKGWFHHpBbVn-GYtRpWU4yM now I don't have any problems

Hello, i have a Passat B7 with Volkswagen Sound System (between Standard and Dynaudio) with a 8-channel amplifier . Anybody knows it is working with isudar or is a rom (like M.I.C. ) avalible that support it?

And why support M.I.C. dynaudio and other not? Is it only software?
[MTCD Android Head Units General] francesco781623:
For me the GPS signal struggles to find it then during the journey it loses it often and willingly even at an intersection the signal disappeared. I had to replace the antenna with that of an old px5 system and the situation improved significantly.

Hello, I have a PX6 rk3399 1280*720 DSP MTCE_LY_V3.52_1 , and the problem I have is noise in the speakers, when I set the sound to 0 the noise is removed, but when I raise the volume to 1 it makes a noise like interference, that noise is always the same from 1 to 20, I leave you a video with the noise, I put it at 0 and 1 if you hear how it cuts and comes back.

it has a solution?

Any one else has this? Solutions?

For the rest the radio is very good. Noise is low but lacks 1080p AHD camera suppprt.

I have Isudar PX6 HU for Mondeo MK4. Is it possible to change the physical button default apps like FM radio or NAVI? Also in the main launcher?
[MTCD Android Head Units General] Bettman66:
You can set the buttons in the factory menu.
[MTCD Android Head Units General] marjanoos:

I was searching there but couldn't find that. To be straight, I want to change radio physical buttons, not my wheel buttons.

[MTCD Android Head Units General] marjanoos:
This is not what I'm looking for. By default physical "FM" button opens default, oem radio app. I have NavRadio+ and want to open that app with the "FM" button. These settings which you have told me about change different things as I believe.
[MTCD Android Head Units General] Bettman66:
I understand what you are looking for, but these settings do not exist. This may be possible with root and renaming the app.

Hi Friends,

I have this radio from ISUDAR:

Hi! I have a problem with this MCU on Passat b7.

It is only showing a parking screen. May I recover it somehow to its original state?:)

I tried to flash it. But my firmware is too new. So no luck.
[MTCD Android Head Units General] Pavel-71:
Try disconnecting the canbus adapter, it may be defective. Or the gear lever may have a bad reverse sensor that detects permanent engagement.

Have you tried restoring the factory settings?

The latest OTA is OLS_rk3399_10.0_ota (20210316).

Hi!

Thank you for your message. I tried to flash with this firmware OLS_rk3399_10.0_ota (20210316). It was succesful. But still same problem.

The thing is I probably changed something in factory settings. I guess this cause the problem. May I revert it back somehow?

By the way, where to find img firmwares?
[MTCD Android Head Units General] Pavel-71:
In the factory setting, only the rear camera is switched on and off after reverse gear is engaged: Factory setting / Other / Prohibit reverse / Disable. Did you make a backup of dmcu.cfg? If so, you can use it to return everything. The procedure is the same as for the MCU update, just use dmcu.cfg. And what IMG firmware do you need? I have already sent you a link to HCT7_rk3399_10.0_IMG (20200415), you can use it or choose from another manufacturer:

[MTCD Android Head Units General] arturkatov:
I did backup. But I already did factory reset and wipe data. So I'm not sure whether it is still at the place.

Anyway, How to check it? How can I connect to the device? Since this file in the internal memory, isn't it?

About IMG. If this file is ok I will check it. It isn't completely clear for me how to get img from there.
[MTCD Android Head Units General] Pavel-71:
You will find the file where you saved it. If you have not copied it to external storage, you will not be able to access it. Installing IMG is done with a cable from a laptop, but that probably doesn't solve your problem.

I think the radio still detects reverse gear, Did you try to disconnect the canbus adapter? It's the box on the main wiring harness. And in order for the radio to go, the red and orange wires must be connected.

If this solves the problem, the canbus adapter is bad, you have to buy a new one.
[MTCD Android Head Units General] arturkatov:
Ok. Thanks. I tried but it doesn't resolve the problem. After disconnecting canbus adapter. MCU doesn't work at all. Only black screen.
[MTCD Android Head Units General] Pavel-71:
You have to turn on the radio with the power button. It's like when the radio is on an external source, it also has to be turned on with the power button.
[MTCD Android Head Units General] arturkatov:
Yes, I tried. Also I tried reset button. MCU red signal blinked several times so I guess it started. But when CAN adapter is disconned it don't have anything to show (I mean car info). So just empty screen.
[MTCD Android Head Units General] arturkatov:
I think probem is rather in firmware than in hardware. But how to fix it...
[MTCD Android Head Units General] Pavel-71:
Get from someone with the same radio dmcu.cfg. Or try the seller, maybe he'll give it to you.
[MTCD Android Head Units General] yukato:
Does anybody have this dmcu.cfg for ISUDAR PX6 here?:)

Even don't know what to do else...

By the way, I did dmcu.cfg import via this menu. It was correct?

They sent me dmcu.img file. May be I need to rename it?
[MTCD Android Head Units General] Pavel-71:
They sent you an MCU update.

dmcu.img- is an MCU update

dmcu.cfg - file to restore to the original state in the factory settings.

!!!! Don't rename !!!!
[MTCD Android Head Units General] arturkatov:
So I still need dmcu.cfg file? dmcu.img won't work in this case, correct?
[MTCD Android Head Units General] Pavel-71:
Yes you still need dmcu.cfg. They sent you an MCU update.
[MTCD Android Head Units General] Bettman66:
On Thread #29 you found a MCU Update with dmcu.cfg.

But you have to be sure that you have a LY MCU.
[MTCD Android Head Units General] arturkatov:
What does it mean "LY"?
[MTCD Android Head Units General] Bettman66:
Have you already read the heading of the thread?

The designation of the MCU used in this thread is LY.
[MTCD Android Head Units General] arturkatov:
Oh, It seems I have GS. But what a difference?
[MTCD Android Head Units General] Pavel-71:
Attention # 29 is not dmcu.cfg. !!!! This is an update to the dmcu.img MCU.
[MTCD Android Head Units General] arturkatov:
It has both.
[MTCD Android Head Units General] Bettman66:
Isudar this is my HeadUnit. The LY Update on Thread #29 works with this.
[MTCD Android Head Units General] Pavel-71:
Okay, but it has a different type with buttons. And he probably doesn't know if he has GS or LY.
[MTCD Android Head Units General] yukato:
The seller sent me GS actually.

But no matter. I tried to install LY cfg. Good news: I got my android back. Bad news - not correct resolution.

So I guess I still need my LY cfg file. Correct? Or it is possible to fix the resolution?

Also, I got two questions after. It would be good if you help me:)

1. If I need to get back the original interface. I need to install another firmware?

2. On some reason sound becomes much better with OLS_rk3399_10.0_ota (20210316) than it was with the original gs16_rk3399_10.0_otapx6(20201215)

How is it possible?

When I only installed this device sound was worse than on my stock RCD-310 but now it is how it should be.
[MTCD Android Head Units General] Pavel-71:
The resolution can be corrected with the dmcu.ext file. Update just like the MCU, only use dmcu.ext instead of dmcu.img. Select the file according to your resolution.

[MTCD Android Head Units General] arturkatov:
I still can't resolve one small problem.

This interface has a light theme as well. Seller it is controlled be headlight. How can I check it? May be I need to switch on smething in configuration?
[MTCD Android Head Units General] Pavel-71:
If I understand your question, then the automatic switching after turning on the lights is in the setting / extra setting / brightness mode / auto, dark, bright. If you do not have daytime running lights from the factory, then the car does not work. You have to switch manually to dark or light.
[MTCD Android Head Units General] Bettman66:
With the GS Android version, the automatic switching did not work for me. Only after updating to the version that Pavel-71 linked.

Hello! The car mechanic replaced the factory head unit with an android isudar px6 vw radio. What I have is a 2009 vw sharan 2.0 pdtdi. Isn't it that the top of the mfa doesn't go where the radio shows your transmitter + volume, but that I noticed today that there are other warning pictograms there as well. There was not enough gasoline and the pictogram did not appear there, but there is the oil + water temperature brake pad, etc. That would be very important, I think. Sy might have a car like this with an android headunit. Or maybe an idea of sg. Bad canbus? Thanks for the reply in advance! In My country nobady can helped!

My Isudar PX6 is working fine. Except music quality. I decided to return to this problem. The thing is if instal dmcu.cfg from LY firmware(I took it here in this tread) sound quality is just fine how it should be. But In in this case I\m getting version uncompatibe info and periodic sound blinking. With my native GS dmcu sound is just too flat and equalizer is not helping much.
