Only took six months of umming and arring 
but the exotic head unit is ordered!: http://www.amazon.co...ailpage_o01_s00
£170 including aerial and SD card. I just have to throw the Golf fascia plate and ISO adaptor away and it's normal head unit. I can dump all my soundz onto an SD card and rock the highway! Whether the DAB will work over here is another question but the 40 year old mini is future-proofed
