After three months of my new iPhone 7 not being able to play any music via Bluetooth in my 2010 mazda car, I finally have troubleshot something and it worked! This is taken me weeks and weeks of trying everything - even resetting my phone multiple times or unpairing my iOS device to my Bluetooth car system and repairing my phone and car. I had tried everything even hoping Apple updates to iOS 10 would work. The culprit? My Apple Watch.
Every time I was in my car, I would try to play music. Every single time, 30 seconds into the song it would get garbled and disconnect, reconnect, disconnect and inevitably would never work.
Finally I put my phone in airplane mode and turned Bluetooth back on. It worked. But I wasn't sold.
Then I turned my phone off of airplane mode and problem resurfaced. But what good is having an iPhone 7 in airplane mode just to listen to music in you car?
So I finally tried airplane mode for my watch (keeping my iPhone in normal operating mode) and it's been 2 full days and not one single issue. I think I've finally figured the most annoying and frustrating issue I've ever had with an apple device in my life.
Try it - if you have a watch this may be the issue!
I have an iPhone 7 running 10.2 and a 1st gen Apple Watch running OS 3.
