iPhone 7 will not play audio through car's USB port.

When I plug my iPhone 7 Plus into my car's ('15 Jeep Grand Cherokee) USB port, the artist/song/podcast information appears on the screen, but the audio only plays through the phone's speakers. I confirmed that my settings are all the same as they were on my 6s Plus, which played with no problems through the USB connection. Bluetooth streaming works fine - no issues at all. Any ideas, or is this a similar issue to the one people are having with CarPlay?

iPhone 7 Plus, iOS 10

I was having the same problem - USB data connection to car stopped working after the iOS update and generated the message “USB ERROR” in one car and “Version Not Supported” in another (both Hondas). None of the suggestions posted online worked for me. Then, when having trouble getting my iPhone to serve as a personal hotspot for my iPad at a conference, I googled that problem. One suggestion was to reset the network settings. I did that and it worked to reestablish the hotspot connection between devices. When I got back in the car an hour later and plugged the same phone into USB to charge, the USB connection was suddenly working again for data as well. I now have music back in the car.

Hope this helps

Swipe up from the bottom of your phone, swipe right, at the bottom change connected device from Bluetooth to dock connector.

Same issue here. Just got a new Iphone 7 - my Subaru Impreza (2012, HU model Clarion CM421LB) doesn't detect via USB. Bluetooth is OK, but I need the charger function while playback.

Previous iPhone 5/5s (also iOS 10) worked fine.

Still didn't work for me even after buying a song off iTunes. If it worked for you, are you able to listen and charge at the same time?

Hi guys:

I had the same issue, after read a lot, I saw an default app called music. This app was accidentally deleted (my daughter). I reinstalled that app and audio through dock port come back again.

Perfect answer, this is what I am exactly looking for . I contacted Apple support through chat and I wasted 1 hour of their useless suggestions.

Turn off Bluetooth befor plugging into the car. Solved the issue for me.
