Hello everyone, I'm dealing with a 2011 cx7, it has hands free Bluetooth and the Bose sound system. A month ago It was rear ended, damage mostly cosmetic, the bumper had some broken clips. the speakers all blew out when the vehicle was hit, not sure if it's related. But In the month the backup camera and radio have begun getting dimmer from what they could see, and now they do not turn on at all. I've replaced a fuse but and checked the rest but it did nothing. They asked me to look into because I'm mechanically inclined but this is over my head
