Bluetooth & iOS 9.3.4 = Bad Speakers
After installing iOS 9.3.4 onto my iPhone 6S Plus, the left speakers in my 2016 Toyota Highlander do not work: Bluetooth may be the culprit - how do I correct this problem, please?

Hi,
Try un pairing your iPhone then re pair > Get help connecting your iPhone, iPad, or iPod touch with your car stereo - Apple Support
