Problems with Audio Q5 settings.
 

We have a 2017 model Q5 that is 18 months old. On a trip just lately the screen showed : Data service not available. Please insert a SIM card. You then have options to accept or cancel. If you select either option it goes back to navigation. After some time the message re appears.
How do I stop this message. There is no SIM card inserted. Any suggestions appreciated.
