Hey guys,
I have two questions. Now that I've got everything running like mtc-keys, start up etc there are only two questions left.
1. If I'm turning on my light of the car the radio is dimming the brightness down. In the night not bad but I like to have my angel eyes turnes on by day, too.
So can this be disabled by software or hardware? There is an extra illumination cable on my unit, maybe if I connect this to power?
2. My steering wheel got a mode button. I would like to change the mapps in this "cyrcle". I dont nee the standard media player or radio. But I would like to have Spotify and PowerAMP there.
Also if im cycling threw the apps, I'm getting to a point where the boot logo shows up and the unit is stucked. Its everytime the same point, looks like an app cant be started. But I dont know which one it should be because all standard media apps are working (radio, dvd, media player, ...)
Thank you guys in advance.
I have the same problem when cycling through apps, I get boot logo looping. Hopefully someone has a fix

Light dimming is done on an MCU level. To my knowledge there is no programmatic way to disable it.
There's a cable you can cut though.
On my unit I have the schematic at the top, and the cable is labelled "Illumination wire", which is orange.
Problem is - there's multiple orange wires.
To narrow down which orange it is, here's what you can do:
Get a voltmeter. Measure voltage coming from the car where one of the orange cables is supposed to go (Plus to orange, minus to ground).
When your headlights are off, it'll be 0V. When you turn on the headlights you'll get 12V. This is the cable to cut.
Thanks for your advice.
My unit got an extra cable, its orange and called illumination but it isnt even installed.
So I thought if I connect this one to a permanent 12V, the illumination should be constant?

Wait, so the orange cable labelled as "illumination" doesn't go anywhere, but the stereo still dims when turning on headlights?
Do you have a canbus box? It's possible that the lights trigger from car goes to canbus box which then sends the signal to stereo via serial, and illumination cable is there as backup. This was my setup with SWC.
If that's the case, see if there's an orange cable going to canbus box and measure voltage on that. This may be the one you need to cut
As for the 12V
The cable triggers dimming.
So, when 12V is supplied, the screen dims (becomes darker)
If you connect the cable to 12V, the screen will be constantly dark, which, to my understanding, is the opposite of what you want.
In either case, check the canbus box first, see if that solves your issue.
If you want to retain the dimming when the lights are on, but not during the day, you could wire in a photocell relay such as this to your canbus illumination wire. Then just snake the photo sensor up near the windshield.
You could also tap into an existing one, if your car is so equipped, but that would mean modifying the stock vehicle wiring.

Yes, exactly.

Yes, I have got a canbus box. I will look for this in some days. The unit isnt that fast to disassemble from my car.

The cable triggers dimming.

Correct, it should be bright the whole time.
Funny thing, today when I was entering my car the illumination didnt work anymore. I tried yesterday to set the keylight trigger in the factory menu, but there was no change and so I canceled this step.
Now there is no more illumination. No matter if headlights are on or off ir anything else.
Will check this again later when I'm back at home.

At my device in Factory Settings if you activate "Keylight" Dimming stops. Even at night and day. You may use this with a work arround: Use "Keylight" to deactivate the function. Download PCV app and use dimming function there. It dims the display depending on the time instead of the light key. So in the evening it dims and in day its full illuminated.
I tried it with activating and deactivating the keylight, and nothing changed.
I managed to dim the illumination of the display by time, but if turning on the headlights its gonna be dimming the unit everytime.
It isnt dimmed by the software, its still on full brightness but not that bright.
However now the key illumination is completely off, and I dont know how to fix it.

Day Brightness 250
Night Brightness 150
Yes, it should shortly dim, but the software restores the old value some seconds after. Thats happen to my unit. Disable keylight to get keylights illuminated back again.
Where to set these values?

Inside PCV App. 2nd Option from the bottom (Edit).
I have malaysk rom which has an option in setting to change brightness between dark, light and auto. Auto is the default setting which dims the screen when the car lights are on but changing it to light keeps the screen bright at all times. I like to keep it at "light" to be able to see the screen during the day when I have my lights on. The downside is that the screen seems to bright at night.
Hi,
I have recently bought an RK3188 Unit (KLD6) and am happily running Malayks ROM on it. However, when I switch on the lights of the car, the unit lowers the brightness of the screen. As I have to use lights during day in some parts of Europe, I would like to manage the brightness of the screen by an app. If it is a bright day and I have to drive with lights switched on, I can barely read the screen anymore. So is there any way to prevent this behavior? I know that I could just remove the lights wire, but I would like to have the LEDs to be switched on or off with the lights.
In case of Mtcd devices such option is in Factory Settings (password to enter it is 126). You can check it in case of your unit. I had the same problem - in my country it is mandatory to use head lights 24h per day so I lost screen visibility during the day.
Thanks for your answer. However, I wasn't able to find any option to turn off the brightness control. Do you remember how it was labeled/called? I found the option to turn on the LEDs permanently and also brightness control for reverse driving, but no option for the brightness with lights switched on.
Thanks in advance.
I found the solution, which obviously was too obvious to be found beforehand by myseld. :/ The normal system settings menu provides a tab 'Display', in which the brightness can be set as 'auto', 'light', and 'Dark', whereas 'Auto' means that the brightness depends on the status of the car lights, 'Light' means bright and 'Dark' means lower brightness.
I am trying to figure out the front panel button illumination in the factory settings. I do have the "illumination" wire connected and is working fine when I set the trigger to sense the lights. But what I really want is that the panel lights turn on when the deck turns on, and I believe I change the trigger to "power". But this seems to not work and when I turn on my car lights the panel will the then illuminate (even when set to "power") . Besides changing the illumination wire to acc is there a setting that I am missing here?
Hello
I bought a 4/32 Px5, android 8, version MTCE_MX_V2.83_1. for a Honda Civic. The model is LM J044.
I see that the mini USB in the front panel next to the sd cards is tapped. They told me that is out of use. Is it correct? When I try to change the illumination to the physical buttons from the "element" option I see only white light that corresponds to the red of the "element". The other yellow and blue are dead. Is it a problem of the led?
And at last, the x icon in the screen dims the brightness and the dimm physical button turns off the screen. I think they must interchange. How can I do this?
thanks
Hello ive updated to the latest mcu available for
Mcte_gs and mow i can use the rgb led light for panel
