I just talked to one of my co-workers that bought a 2011 X5. He got the full map update as he plans on being here for 5 more years. He said that they did the update at the dealership and when he asked for the disks, they told him that they would hold on to them for him... That he wouldnt be needing them for anything else. He said he didnt push it.
