About to take ownership of a 2015 Audi Q5 with a Concert audio system. Ultimately I'd like to upgrade to RSNav if they manage to get the larger screens set up for RHD vehicles (I am in the UK) but in the meantime I was looking around for an AMI port to attached a Bluetooth receiver to in order to get Bluetooth audio. My understanding is that this should give me better quality sound than AUX (although I guess this will be marginal at best).

There is no AMI port in the arm rest (there is an AUX) and I cannot see one in the glovebox. The space where a CD changer would go has some kind of felt lining around it instead:

So, my questions are:
Is there an AMI port in my glovebox? Maybe behind the felt box?
If so, what is the best way to remove the box/gain access to the AMI port?
Is it worth using AMI instead of AUX?

Thanks in advance
