yes (had the last two  mapped at my house ) , no doubt you could get live mapping at a price, the generic maps are developed in this country, so they are better suited to the fuel and temps we have, I have had slightly better mpg, much quicker and a smoother throttle response when mapped 
  
cars I've had done :- 335D coupe, 320D, 530D, clio dci, seat leon's x2, golf gttdi
