iPhone7 Bluetooth issue in the car

My brand new Iphone7 seems to have bluetooth problems in my car. Everything works but the sound drops sometimes (often) when I listen to music. I didnt have this issue wiyh my 6s and IOS10. I tried to reset everything but the problem persists. The iPhone is recognized by the radio inmy Toyota, but the sound drops just as it was a radio in a tunnel.

iPhone 7, iOS 10

Thanks for the follow-up here. I guess now I need to find out the specification of the new BT chip/protocol and what the requirements are in order to be compatible with that. Then find out what the BT specification of my car. If those don't match, I'll have to find a feasible way to either downgrade the BT protocol of the phone or upgrade BT of the car.


If that is all true, I really want to hear from Apple how they justify the decision of making their BT protocol incompatible with many cars on the road, and more importantly all the pains this brings to its customers.

One thing I would also like to point out is that though the GSM Model A1784 is indeed an unlocked phone, it will not work on CDMA networks of Verizon or Sprint, but Model A1661 will work on all carriers in the US. It is interesting the Genius Bar employee still thinks it is the car. I can tell you that it is not the car. My reasons are simple.

  • When turning off LTE Data on my AT&T iPhone 7 plus Bluetooth works perfectly.
  • I switched to Verizon this past weekend and Bluetooth with that phone (Model #A1661) is working perfectly in my car.

  • I really wished Apple would admit that it is not the car, but the new Intel Cellular Radios.

    I've a similar issue with my iPhone 7, but i don't be sure if it's the same...


    While I'm driving with Carplay and Music or Podcast, around 10 or 15 minutes I get no sound from any speaker.

    I've own a 2016 Skoda Octavia RS, and before iPhone 7 I had no issues with it.


    What I didn't read here, is a tip that I've found (at least in my case). When I get no sound, I call Siri (dedicated wheel button), then I ask for wheater or simple nothing. After Siri respond me or I cancel Siri, I get sound back again.


    This same issue is happening to me with new airpods, and the workaround is the same, call to Siri and then sound came back.


    Is anyone of you having same issue or workaround as I have describe?


    Regards, (and sorry for my poor english) 🙂

    I switched to Verizon, but you can purchase a SIM Free iPhone from Apple. It should be the Verizon Model or you can purchase a Verizon Model iPhone from Apple. Like I said I believe it is the new Intel Cellular Chip causing the issue for AT&T customers. I purchased a new SIM card from AT&T and that did not help. Apple replaced the iPhone already and that didn't help.


    In the end I simply decided to make the move to Verizon because my experience as a whole with AT&T was slipping and the Bluetooth issue was the straw that broke the camel's back. Also note that the Verizon model has the old Qualcomm chip that was in the iPhone 6s. I will test an active AT&T SIM in my Verizon later this week to confirm my theory. I am out town at the moment or else I could share the results with you today.

    So how did you convince Apple to swap your AT&T iPhone for the Verizon model? I got mine through the Apple Upgrade Program. I was thinking of switching to Verizon after my upgrade anyway but didn't realize that the AT&T version doesn't support CDMA before I got it. This was highly misleading in my opinion since the 6S and 6S Plus were "global" phones that worked on AT&T/Verizon.
