I mistakenly ordered my last F11 without DAB, the dealer installed a BMW retrofit for about £150 (I think) it was okay but would drop out now and again. Although this was about 3 or 4 years ago, they might still do them. Compliments of the season Carl.
Thanks Carl , BMW do retro fit DAB but it doesn't work with early gen idrive , after looking , cheapest option looks DABmotion , separate dab tunner that converts to fm , odd but gives loads more stations for about £100 , might see if I can try one first . Seasons greetings to you too sir. Ray
