I just upgraded to a new iPhone 6s from an iPhone 6. I have a 2015 Toyota Corolla and I like to use the built-in Bluetooth for listening to podcasts and music. It worked perfectly with my iPhone 6. But with the iPhone 6s I experience frequent glitches where the audio skips or cuts out for half a second or so. This does not happen using a Bluetooth speaker or headphones. When I got the new iPhone 6s I backed up my iPhone 6 to my MacBook and restored the 6s from that backup. I have tried forgetting the Bluetooth connection to the car and re-pairing but that has not helped.
