The bluetooth works for the iphone. Just follow the manual from lexus and once you receive the pairing code from your phone enter it into bluetooth screen on your radio. It takes 2 minutes to set up.
One problem I have had so far is that the phone has a delay when you first connect to bluetooth when making an outing going call. So the person on the other line will say hello, hello, hello, before you hear it once.
Good luck!
