i cant get my new iphone 5s to pair with my BMW. i input the code and it still doesn't pair.... help, i drive alldaya nd need hands free!

Have you visited the BMW dealership to speak with them regarding this? I have a VW Golf and my links in perfectly so it sounds like you might need a software update for your car or there may be issues the rejection of the code seems like it's able to communicate with the system but the code being kicked back so the car is probably the issue.
