My Q5 allows me to connect with my iPhone 12 Pro Max to make and receive calls. 
however I cannot play my iTunes music or google maps through the Bluetooth  ? 
I can connect to the 3.5mm jack in the arm rest but this means having the wire. 
my question is, Is there a device that I can use to make them wireless?

any advice would be great. 
thanks for reading 

Clint. 

Sounds like you need to upgrade your MMI  software to latest version.

This have solved the problem. 
if phone rings via car Bluetooth the music stops, then returns after phone conversation has finished 😁http://Bluetooth 5.0 Receiver, MaedHawk Bluetooth Aux Adapter/Portable Wireless Audio Car Kit (A2DP, Built in Microphone, Dual Link) with 3.5mm Jack for Home Music Streaming Stereo,Headphones,Speakers https://www.amazon.co.uk/dp/B086VZQG55/ref=cm_sw_r_cp_api_fabc_4PAW9F835VNPYHAKMZ0M?_encoding=UTF8&psc=1
