Hi. Discovered the following problem with FM radio reception in recently bought Kadjar 2017. While driving treble sounds of FM radio stations are fading from time to time and after this recover its level again.
Here is the link for video https://photos.app.goo.gl/f3v44BK4AzXxfGRN9
Can somebody help me to determine the possible reason and ways to solve the problem. Thanks.

The car is probably detecting speed limit signs, but the audio warning is set too low. When making such kind of announcement, the car lowers the radio/music sound for a second or two.

Sign recognition is disabled in my car. The volume of the music is not changing - only the high frequencies of the timbre (trebles).

Are you using nav guidance when this happens?
By the way, when going by traffic lights, and other devices, which use radio connection, could also be the culprit.

Nav guidance works OK and doesnt influence the quality of FM radio (one can hear it at the end of the video link). It looks like that hardware is the reason. The question is which one? The connection of the aerial or the very head unit? By the way, what kind of aerial is in the car - passive one, or active with the signal amplifier? Are there electric diagrams of the head unit and of the aerial available?

Music from USB and Bluetooth is playing without any problems. Only FM reception is faulty
