How do I get a navigation system on the Mirror Link Radio ?

Hello guys. I’m new here, we finally got our new Arona FR. And already the first problems appear. We both have Samsung mobile,s,and had to fix the mirror link from Samsung no longer supported. My question, my mobile phone I can connect to the car via USB,and let me Dan with Google Map routes. My wife,on the other hand, is extremely difficult with it. In short, how do I get a functioning navigation system installed on the radio? Or I could somehow make the SD card slot read by the SD card if there is a card, inserted with a NaviSystem on it, what would I have to consider when writing it on card. Thank you very much in advance for your answers.
