Hmmm, I do get the signal strength. Maybe you can check with BMW and see if they have an update to iDrive system.

the only thing that doesn't seem to work is the signal strength display. with my moto Q, the car could actually monitor my signal strength. it showed a little bar icon near the time. don't get that with the iphone, otherwise everything else seems to work the same, although i haven't really tested it that much.
