You have gone to alot of trouble to get DAB+, I have it in my X5 and its is great, the amount of stations is unreal, pity they are only in the major cities.
I have been working on getting BMW Apps, nearly there, about another week, have Pandora, as its allowed again, they had band IP address from overseas but it changed in July.
You should try it, just nominate your artist and it plays all there songs, its probably better than DAB.
Also I can now get SMS & eMails on the iDrive, when driving just push play and they are read out!
X5 F15 M50d White, 20"rims, Yellow Calipers, Ceramic Pads. Better off saying what it does not have and that's a B&O Audio System, otherwise all option boxes are ticked.
