Installing Bluetooth for satnav/ Music from IPhone

[Scwaller]

Hello! I bought a q5 last week, 2016 model. I would to use my phone as satnav as there isn’t one installed. I want to do this wirelessly, connecting my phone to the Audi stereo via Bluetooth. 

There is no sign of any 30 pin cables in the glove box or anywhere else. Only a simple headphone jack in the central armrest. 

Can any advise how I can achieve Bluetooth connectivity to use satnav and music, wirelessly from iPhone 10 to car stereo. 

(Phone calls work via the blue tooth system but not music or satnav) 

 

thanks in advance!!
