Good evening.
When you say « through the aux », how do you actually connect your phone as there is no headphone jack on your iPhone 7? With a dongle in the Lightning port OR are you doing it through Bluetooth?
I connect my old iPhone 5s to my car bluetooth all the time and wearing my Apple Watch - so both using my phone’s Bluetooth a the same time - and never had any issue like yours.
The first thing to check is the reliability of whatever cable - if using one - is connected to your iPhone, losing the contact for a split second will send the audio back to your iPhone exactly as you describe.
Do you have another speaker you could connect the same way you do in your car and see if you get the same behavior? If what you think is happening is indeed the issue then you have a hardware problem. That is something that can only be solved with Apple support.
When I play my music I play it from an actual aux cord and it’ll work through it until I check my watch then it stops and just plays through my phone speakers not the car and it’ll only play through the car once I disconnect my watch but I wanna keep it connected for my notifications
The interaction you describe between your iPhone Bluetooth connection to your watch and your phone sound output (through a jack, or in the case of you iPhone 7 I assume through the lightning port) is ... surprising. It makes little sense for now so that’s why I am asking you for more information and to run a test.
Please help me help you.
1. I understand you enter through the aux port in your car stereo. It’s the other end of that cable that interests me. In what port on your iPhone do you connect it? On an iPhone 7 it cannot be a headphone jack, you either use a special aux cable or a dongle connected to your iPhone Lightning port. Or maybe you found another way.
2. The last part of my previous post is a simple test. I suggest your run it and see if you get the same issue there.
good luck
