Driver side sun visor broke off! Car was dead and had to be jumped off the next day. Once it was jumped off the radio, gps, and some interior lights were not working and I could only use the key out of my key fob to continue working until I got it to the Mazda dealership.

Mazda dealership informed me that the visor has a sensor in it that caused the malfunction of the radio, gps, and interior lights and would have to be replaced. Paid $353 to get a new visor.

However the sound quality is not the same. Regardless if I have the radio on or the Bluetooth on the Bose sound quality is very poor audio quality. Have checked the settings several times for the sound and it’s not the same.

Is there anything I can do to get the quality back before all of this happened? Could this issue be due to me frying the speakers when it shorted out?
