Hello I wld like to ask how to actually use cd magazine in bmw e60? Correct me if im wrong but it's located inside the dashboard right? So basically i have inserted like 4 discs and i will be able to just change the cd without having to get it out and insert manually right? But still i dont know how to use it cos i have all the discs inserted and when in idrive, i cant seem to play cd unless i insert it manually. Can someone help? Like how to use it in a correct way cos i think it doesnt work that way. Many thanksss
