I drive a vauxhall zafira 2015 plate. It has aux, which I currently use via a usb C to aux jack. It also has a usb port which no matter what I try, I cannot connect my phone for music or calls.
My wife's iPhone does this with no problem.
There is no Bluetooth and it is an old fashioned info screen I.e. just radio station name and temperature etc. No navigation or touch screen.
Has anyone come up with a solution to get audio through the USB
