Welcome to the e91 club.
What are the options on your e91? Does it have bluetooth?
You probably can get a lot better integration if you do the MULF2 retrofit. Search the boards and google 6FL retrofit for more info. If you don't know what options you have ask your friendly dealer to run the vin and print out the build sheet for you, or google BMW vin decoder.
