Exactly the same thing happens to me, I have had OAP in the car for 3 years and I have not been able to find a solution to the electrical noise emitted by the raspberry, I am attaching a diagram of how I have everything assembled in case it gives you an idea of why it may be.
I have also tried to connect the pi to ground of the car at different points and nothing works, if I move the cable that goes from the sound card to the usb card it changes in more or less intensity but the noise is still there.
