How can I synch my phone with my Audi's MMI system?

I recently purchased a new Audi and am having trouble connecting my phone to the MMI system. I have tried following the instructions in the manual but it still won't connect. Any tips on how to resolve this issue?

First, make sure your phone is compatible with the MMI system. Some older phone models may not be able to connect. If your phone is compatible, try restarting both your phone and the MMI system. Also, check if there are any software updates for your phone or MMI system.
