I have a 2011 X5 and would like to install a backup camera. I've been doing a lot of research and realize that I must get a kit that works with the new iDrive and CIC navigation. I've found these two. I contacted both vendors and confirmed that they are compatible with my X5. However, the price of the first is $500 and the price of the second is about $1,000 (depending on camera choice). I would really appreciate any input I could get on which system to choose, or the differences between the two.
