Radio/tape Cd Player problems of the 2012 Toyota Prius

The navigation, bluetooth & radio system was turned off on it own and became corrupted when the car dealership tried to update the systems software. The hardware was then rendered inoperable and the systems computer was then replaced, the warranty did not cover the defects in the system. The estimated repair exceeded $1000us. Due to the dealerships actions in trying to run a software update, the repair costs were paid by the dealership. The failure of the computer system seemed to be known by the car dealer. Toyota was never directly contacted by car owner as only the car dealer handled the repair issues.
