Weird Static noise from 2018 CX5 GT Bose sound system

The noise only appears when the engine is running. No noise at all if I only turn on the power. It can be loud sometimes, and sometimes it disappears(mostly during winter)...I have waited for like 7 months but no response from Mazda official(My dealer said they have reported this issue) yet...Does anyone have this issue?

A guy in dealer said it's my dashcam is interfering, but I have unplugged every extra electronic but the noise still exists.

I have never heard this kind of noise...Need help...

Here is my record of the noise:

Noise starts from 10-sec mark. The startup music is just my dashcam.

Thanks

Did you overcome these problems and how, my Mazda cx5 is making the same noise?

Welcome to the forum.

You may look to see that members has not returned to post anything since 2019.

Check with your local dealer, there is a service bulletin regarding static noise from the audio. Not sure what vehicles it covers.
