Have had a call back from the UK office. Apparently, the map service is provided by a 3rd party, it seems there is only 1 update each year, so I have been told, and the guy who rang me, "thinks" there is a charge for updating? As my map in my brand new A3 is not up to date, I wasn't too impressed with his response, although he's going to investigate and get back to me. The story continues!
