I have a 2006 330i with the pro audio (no iDrive) and I get the signal strength display with the iPhone. With the Q I only got the strength when I started the car or was on a call. Normally it didn't update. With the iPhone it seems to update the strength as the signal changes. I love it!

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.
