Went out today nothing more than normal & after a stop off at the shops, the radio (rns 310) is now asking for the code to be entered??, Thing is ive only had it 3 months & the code didn't come with it, why did it do this & whats the cheapest way out for me?, fed up at the mo its my first vw after many years as a vx owner & was looking forward to less problems. Any suggestions would be greatfull.
