Sorry for my inaccuracy.. I'll try to make sound clip as possible as I can. The noise is only heard throught FM tuner mode (for example, no crackles in AUX mode when playing from phone). That noise comes throught antenna, that static radio noise (as it would be poor quality signal) but only for short periods and many times. There was no noise with my old radio.. So I think its not the antenna problem.It's passive antenna. Tried to conenect FM amplifier - nothing helped. Is this new sony car radio unit so bad, that it can't clearly keep tuned stations? Because every station it tunes, that FM noise comes, sometimes seems that other station tries to get into this one I am listening.
