NHTSA Complaint #11690851 — 2020 MAZDA CX-5

I purchased this vehicle as a used car from a dealership. On my way home, the infotainment panel began to shout at top volume that this is the volume that navigation would be set at. The volume was so loud that it was startling, and it continued on until I had to pull over. I contacted the dealer, but they offered no assistance. The car continues to control itself at the panel ferning with the use of android auto so that you can't use your phone GPS for directions. The radio will control itself, changing stations, making loud beeps, and turning the volume up. There is no way to stop this feature because you can't turn the system completely off while the car is on. I can find no way to fix this on my own. I have tried resets, but have seen ample information about other people having this problem online. This does not seem to be an unknown problem and I don't know why there has not been issued a recall because it's very dangerous.
