It appears that my 2011 Leon 1.2 TSI is a "GoodStuff" model, which means it has had bluetooth fitted as an option (It didn't come as standard from what I can see but I can confirm it's there because I use it) but the A2DP functionality doesn't seem to be activated (or available).
I'm guessing that I have to switch the Bluetooth unit for the one in the later Copa SE but first I'm going to try to find out if it's possibly just a switchable option in VAG-COM. If it is, then that one thing justifies purchasing VAG-COM ... otherwise I guess I have to either replace the BT unit or get one of those Chinese Windows-based touch screen (pseudo RNS 510) units to fit in the radio hole and drive that with the phone instead.
Any insight would be appreciated and in the meantime I'll keep trying lots of different search terms
