Boys and girls, I bought my new 2012 navigation disks from
www.bmwnavigation.co.uk,
I got the FULL 3 DVDs, SET and V3.2 update disk all for £25, Bargain! and helpful service.
Instructon Manual and Navigation guides (included) for all BMWs on this site too, so good to bookmark and hope this helps.
Oh, and I almost forgot, you get to choose from about 40+ custom splash screens for free!! a wonderful service. <3 and they have a special offer.
