You can get a decent FM RCD510 on ebay with traffic news if you are not bothered about DAB (not Chinese versions which do not have traffic news). DAB requires an additional amplifier at about £70 on top of the radio price plus additional wiring. Occasionally dealers advertise RCD510 when upgrading for a customer - that is how I got mine brand new a while ago when replacing the RCD310 at a fraction of the list price. I already had DAB so it was just plug and play.
