Intermittent Beep Sound

This is an abbreviated Title taken from a previous post which was outdated and I could not respond:
"Beep or Pop Sound from Infotainment System on most Gen 7 Mazda Connects using NNG Navigation"
Suddenly, and with no cell phone in my car, I started to hear an intermittent beep sound. Very random, and while I'm
driving the car. And of course, might I add, very annoying. Not sure where it's coming from, but assume my speakers.
Turbo w/Premium Plus, almost one year old. 17K miles.

Any ideas? I will call my never responsive and just awful "Service Advisor" later and will try and record the sound and attach here
later.

Many thanks!
