A6 C7 no USB & AMI cable doesn't recognise iPhone 16

[Jdah]

 Hi All

I've recently acquired a 2018 A6 avant, it doesn't appear to have any USB sockets only the AMI socket under the armrest 

There's an AMI cable connected with male USB mini and USB c adapter, it fits my iPhone and charges but the MMI system does not recognise the phone ( the phone connects to telephone function via bluetooth ok )

software ver: RMC_EU_P16342  if that helps 

The AMI cable is dated March '09 ?

I'd welcome any possible solutions on offer or recommendations 

Thanks for any thoughts 

A
