A70 fails to connect to car via USB

Bumping a previous post that didn't get a solution.

I'm unable to play music from my phone when connected to USB. 

I'm given different options for connection, which one allows me to play music?

@a70autobot,

Have you tried using an alternate phone to connect a car using USB? Also, check with any alternative USB cable.

old iPhone worked no problem with the car. the usb cable is brand new and not dollar store brand or anything. car also brand new

Your in developer options and it's advising for Mac stuff? I guess make sure you have those apps installed 🤷
Definately do what @Jeremie said 👍
For me I've had bad updates on the vehicle and bad updates on the phone (both IPhone and ANDROID) , good luck getting an update or downgrade from the dealership 🤦
So first id ask if you recently updated? If so you might need to clear cache

If that doesn't help or you didn't upgrade I would try rolling back the app.
Personally I just use Bluetooth and do this...
I still plug it in to charge but I want videos 🤪 so this is road I'm riding 🙃🤙👍
