Hi @linz28 ,
I think that this guide will help you connect your A12 with your car: https://www.samsung.com/uk/support/mobile-devices/connecting-to-a-car/
Let me know if you need help doing this or provide me with more information about the issue so I can assist you accordingly. Have you ever been able to connect this? How are you trying to connect these and do you get any error codes or messages?
