Hya rich.sd card will have to be activated by Audi main dealer or an independent Audi dealer.My independent Audi dealer has the equipment to do it.There is a charge for doing it. ive been a customer with the dealer for 20 years and bought several cars from him he won’t charge me for this.The car was advertised with satnav so he was obliged to sort it out .Should be the same with your dealer.Best of luck.
