Installed the Carlinkit Wireless Apple CarPlay for the F30 (NBT). They also make the kit for the CIC which is the older version of the head unit. This unit will work for 1/2/3/5/7, X1-X6 Series. This is definitely the more budget friendly option on upgrading your headunit, especially if you don’t have navigation. iDrive 5/6 retrofits can cost up to $1,000-1,500 after labor and coding is done. For $300 and an afternoon Sunday you can upgrade the stock head unit to have wireless Apple CarPlay!
Some might dislike Apple CarPlay but I think personally with the iDrive ergonomics and button layout, it pairs well with Apple CarPlay. Having everything you need (Spotify, Apple Music, Google Maps, Waze) in one user interface is awesome. And if you get tired of Apple CarPlay you can also switch back and forth between iDrive!
Install process was pretty easy as well! I did a YouTube video for the install process and a walkthrough on the system.
