To get RSAP you need the Premium Telephone kit which is available in every market except the UK. In the UK only the advanced telephone kit is available with the induction box to try and improve the phone signal. If they offered the RSAP system, the induction box, which only seems to work for iphones, wouldn't be necessary. Different phones have different versions of the HFP, (hands free protocol) (which is what UK Mk7s connect through) they offer different functionality but they all still rely on the phone's own aerial, unlike RSAP. No one at VW UK seems to know why they don't offer the Premium kit but I think it is either an attempt to encourage people to buy an Audi that does offer it or because someone at VW thinks people only buy iPhones.
I have the advanced telephone kit and to get any improvement in phone signal with my Galaxy S3 requires you to take the phone out of its case first and even then its very marginal. I ended up getting VW to refund me the cost of the advanced telephone kit and I intend to get an aftermarket premium (RSAP) telephone kit fitted.
