At a standstill once it lights up brighter and once it lights up dimly, and when I drive a car the same situation once it fades once more strongly. I heard that it depends on the dimmer in the car...

Check the power cube connection carefully. Chinese radios have various additions. An external microphone cannot be connected.

The power connector is securely connected.
When I start the lights, the backlight dims as it should be, but when I go under the lighthouse, it will light up for a moment it is not necessarily the lighthouse.

Insert a description of the cubes of the radio, and in which car it is mounted.

adimen100 · Answer

The cubes are not described but I add a picture:

It is fitted to the first generation Skoda SuperB.
- yellow cable is for reversing camera (B +)
-Red is connected to the mass of the radio, so that you can watch MP4 while driving (without Video Warning)

According to descriptions from the internet, this radio has no backlight input, so I don't know which cable you connected it to.

adimen100 · Answer

I hooked up as the ankle points to it. Maybe there is a dusk sensor on the radio or something.

piotrek22101 · Answer

Just because the car has a cable in the cube does not mean that it is also on the radio. You can cover the radio or illuminate something and see if something changes.

I have already tried to use candles to do nothing. But when the headlights light up at night, the radio dims itself. And every now and then it will shine harder.

In the radio cube, did you have a cable in the manual described as: backlight, ill.?

adimen100 · Answer

Here is the cube diagram:

piotrek22101 · Answer

Where is the backlight in this description? There is only weight with manual and reverse, and steering from the steering wheel.
Anyway, this red one should be connected to the ground cable from the car installation, not to the screw. According to the ISO standard, this is the main mass.

Supply voltage drops after switching on the lights or radio defective. Good point. Probably now the radio is taking ground power on the antenna cable which is unacceptable and may cause the described symptoms.

adimen100 · Answer

When I am driving without lights, sometimes it flashes harder as if somewhere there was a sensor. And one more question, can you upload a different startup logo to it?

piotrek22101 · Answer

First of all correctly connect the radio, as for the logo, some radios have other pre-loaded, depending on the model, check the instructions

adimen100 · Answer

I will connect as you wrote this cable, not under the screw, but under the ground and we will see what will happen

Of course I will share the information.

Ed. I did as you said, i.e. this cable with a screw to ground and certainly improved the quality of FM and the issue with backlight I will see at night what will happen now, thank you for now

Added after 19 [hours] 7 [minutes]:

The backlight at night keeps flashing or does anyone know how to solve it?

miecho18 · Answer

Have the radio repaired.

adimen100 · Answer

I'll give it back for repair

adimen100 · Answer

Everything is normal after repair.
