Yes - I was going to replace mine in view of FM being switched off but now it has had a stay of execution because of the lack of 'take up' of dab I decided not to proceed. I was told about the PURE add on but that was priced at £289 fitted which was to close to the exchange unit. It come as a complete unit with the control knobs - there is a VW sales leaflet - just go and shout at your dealer
I have unlimited data on my phone contract and use an app called TuneIn radio which has nearly every radio station in the world listed!
I connect it via bluetooth to maps & more and listen all sort of weird and wonderful stations.
IMHO it's better than dab
