For my 2013 Prius C, it happened before but didn't do much, maybe once a while (months). I noticed the sound came up when I was driving and first thought it was from my phone. I was out today with my wife and the sound came up couple times, randomly, but every couple mins. Both of us can confirm this is from the vehicle, not from our phone. I remember I heard that sound before, I mean this sound was part of the raidio's notification system, but I can't recall what it is. Any one has the same experience? Like pulling the sword out. There is nothing on the display or dashboard. The radio didn't reboot, no black screen at all.
emm. I figured it out.. Not from the vehicle... It's from the car dash camera. Thank you for your help.
Nice that you figured it out. I understand that now that you say dash cam. I have cheap dash cams and when they turn on/off there is a bell/chime music it makes and it is very garbled to where is sounds similar to what you are saying "pulling sword out"
