2013 Chevy Tahoe stock stereo. I recently noticed that I’m getting some sort of a feedback when driving with Bluetooth on. The person on the opposite end of the phone call keeps hearing a whistle that sounds like a turbo spooling. It doesn’t do it when sitting at idle in driveway and yes i made sure all windows were shut. If i put them on regular speaker phone they dont hear any whistle so it has something to do with the Bluetooth and maybe some interference? Has anybody ever heard of anything like this?
