Anyone can confirm that with GS V3.40_3 Radio fm Alternative Frequency (AF) is working correctly?

I was on Hal9k Android 8 and MCU V3.07 and it was working, then I switch to Hal9k Android 9 and V3.40_3 and it was not working anymore. Then I downgrade the MCU to V3.07 , remaining on Android 9, but it is still not working

Mtce is an upgrade of mtcd.
[MTCD Android Head Units General] royalhawk2002:
Regarding the AF function, I would like to share with you my last findings. I noticed that some time AF were working, but the level of signal had to became very weak before the unit triggers the alternate frequency. I discovered that in the "Other" TAB of the MCU , there is a setting relevant to the Signal Level (was set to 20dB). This setting is defining the level of radio signal on which the MCU triggers the Radio Chip frequency change (to Alternate one).

Setting this value to 30 dB, means that the trigger of the AF is performed by the MCU when the signal has only some glitch, I verified that now the AF is working much better.

The setting is not affecting the normal stations search, since it affected only by "LOC/DX" setting.

As side information, I remember that in one of the old versions of the MCU, the value was at 30dB, not 20 dB (as in V3.40).

Hope it helps

MCU after update problem with button illumination

Hi everyone. I have a Isudar PX5 Android 9.0 navigation for BMW e39, and i tried to update my MCU. My MCU system came from factory with MTCE_GS_V3.30_3 (Aug 6 2019), and i updated it to the MTCE_GS_V3.44_1 (Feb 25 2020).

My only problem is that now, after i updated the MCU, my buttons from the navigations dont light up at all, and my "element tab, or element settings" from where I could have change the color of the buttons, is gone, cant find it anywhere... the button illumination wors only when i try another update on the MCU and then the buttons flash. Otherwise they dont light up at all. Its really annoying. Also my setup button is not working now after the update.

I tried the factory settings 126 combination and put the system to turn the buttons on by power/by headlights or by power + headlights... with no succes.

I would appreciate a lot, if someone could help me fix this annoying thing, it drives me crazy knowing it worked, and after the update it doesnt.. Does anyone have my original MCU version : MTCE_GS_V3.30_3 (Aug 6 2019) ?

I couldnt find it anywhere...

Hello

I have a Isudar PX6 DSP.

I have the amplifier connected via RCA to the 'Subwoofer Out' connection on the radio.

Everything works OK at first, but after shutting down (turning off car/leaving car), the output is not working. I can hear the subwoofer just 'throbbing?' But no respons.

Only way to get it back to work again is to disconnect the radio from the car and reconnect it. (Now i am taking out the car's radio fuse and putting it back in).

Can anybody help me with this issue ? ? ?

MCU Version

MTCE_GS_V3.44_3

RK3399 - Android 10.

Thanks in advance
[MTCD Android Head Units General] Josoft:
Hello,

In the MCU parameters there is an option to switch from

MTCE_GS_V3.44_1 has MTCE_GS_V3.44_3 which is the same MCU but with different options

If you don't find it, I'll take some pictures to show you exactly where it is.

Edit :

it's on the Other tab:
[MTCD Android Head Units General] MediaTerraneo:
Hi, here is MTCE_GS_V3.40 https://yadi.sk/d/Ol2k90izftC7Yw . It's not exactly the one you are looking for; it's newer than your original one and is also older than the version may have introduced those issue. Try to flash that intermediate version so that you could solve those issues and have some advanteges (if I'm not wrong 3.40 introduced something new with the steering wheel management).

---------- Post added at 03:34 PM ---------- Previous post was at 03:22 PM ----------

That's interesting. Please can you provide with the download links for V3.44_1 & Ve.44_3? Is there a V3.44_2 too? And can you explain options please?

Edit:

Edit: here is a collection 3.30, 3.40, 3.44 https://yadi.sk/d/umCvHqCDzHccr/MCU for MTCD, MTCE, MTCP, Intel Sofia3g/GS

[MTCD Android Head Units General] Josoft:
Specification _1 or _2 or _3 is set in the MCU option panel under the "Other" tab.
[MTCD Android Head Units General] marchnz:
Just change version from factory setting and see if it resolves the issue. The sub number of version mcu (vxxx_x) is probably not related, sounds like a guess assuming _1 somehow relates to type as type is set in factory settings.

---------- Post added at 07:18 AM ---------- Previous post was at 07:09 AM ----------

No, its a different revision of the update, not type. Type is set by defining Type in factory settings, not the MCU if the MCU used to flash is the manufacturer for your unit.

The issue is that the person flashed an MCU, which seems to have reset his factor settings. this can be avoided by documenting factory settings prior to flashing and exporting the factory settings configuration prior to flashing the MCU.

---------- Post added at 07:21 AM ---------- Previous post was at 07:18 AM ----------

Its because your factory settings were reset during a flash of MCU. Just try changing the settings - first version - until you find working settings. Backup what you have first so at least you have a starting point that can be reset in recovery if something bad happens.
[MTCD Android Head Units General] MediaTerraneo:
Yes, looking at the image I remembered that I had already tried to tweak about that setting. I forgot about it because none of the 4 versions ever showed differences in the behavior of the HU. In this I think that the problem of [MENTION=10931841]colocolo94[/MENTION] can be solved by flashing the dmcu.cfg, which unfortunately he did not export before the update, but which could require to the dealer or requiring to export to those who have his same HU model.
[MTCD Android Head Units General] marchnz:
Again, incorrect - just configure factory settings and try changing version if buttons or illumination do not work.

Also, hard reset the unit - first try completely disconnecting power to the head unit for about 10 minutes then retest.
[MTCD Android Head Units General] MediaTerraneo:
Hi, maybe there is something confused :)

1. It is not me who has the problem with the lights. Yesterday I installed v3.44 just to make an update; with the occasion I tried the 4 versions available and I didn't notice any difference for my HU.

2 the _1 ... _4 are absolutely not different releases and there would be nothing more illogical than doing 4 different releases at the same time for the same object: the release is unique, the MCU is unique. The 4 versions refer to possible setting differences related to any HW differences.

3 Once the version has been set in the factory menu, simply restart by exiting the menu to apply and make the change effective: you can see that in the HU info the name of the chosen version appears after the firmware version: e.g. MTCE_GS_V3.44_1 if Version1 has been set, MTCE_GS_V3.44_2 if Version2 has been set ... but this does not mean that the release is different, it remains unique.

4 The new set can be observed without having to disconnect the power supply. Disconnecting power is an urban legend. Although in some situations, it may be useful for some electronic objects, this is not the case: on this HU there are no sensors that tend to polarize. It is not necessary even after installing a new ROM. A case in which it can be useful is sometimes the wrong SW communication, but it is generally sufficient to turn off and on again without waiting for much, I have mounted a switch for the purpose.
[MTCD Android Head Units General] theetz:
Just a quick question, possibly a stupid one: are mcu versions absolute or vendor-related? Meaning say i change vendor and version, any chance it might he older even if the version number goes up?
[MTCD Android Head Units General] marchnz:
No one knows, unless analysing the MCU code by reverse engineering.

Ive said this alot, I doubt the chinese fix their buggy MCU code, what they might be adding is new vehicle CAN support; updating your MCU is usually pointless.
[MTCD Android Head Units General] typos1:
Have to disagree with you there, firstly it isnt necessarily "Chinese" code", its code for ST Microelectronics (a French Italian company), it may or may not be Chinese written we just dont know, I would guess that its both Chinese and non Chinese written.

Sure, new CAN versions are added, but other things are also fixed or added, didnt you see the MCU changelog that appeared a few years back ?

There are a fair number of people who have reported that upgrading the MCU version has sorted problems over the years and also a small minority that have said that doing so has created them.

Generally l ve always said that its best to update the MCU when you can, always getting the mcu.cfg just in case there is a problem.
[MTCD Android Head Units General] marchnz:
Hi,

From my experience the only 'upgrade' experienced was sleep mode and fixes being subwoofer output control and reliable steering wheel controls.

Others have reported all number of remarkable anecdotes :)

My thinking from experience is, unless hardware or version of Android has changed and features such as subwoofer/audio control is OK, leave the MCU. We know what the MCU controls and how it works. Often bug fixes might be made in the Android code that interoperates with the MCU and not the MCU itself. Upgrades are required when both Android and MCU code is required to support a feature.
