radio vordon ht-869v2 IPhone 7 - Mirror link how to connect with iPhone

Hello, I bought this radio and probably searched the whole Internet, but I did not find the answer. What is displayed on the radio screen does not help. How can I connect the radio to the phone? The description says that it supports ios. I am asking for help how to connect it, I bought the radio mainly with this function in mind. By the way, how is the internet on this radio? How to connect the internet from your phone. Thank you in advance for your help.
