A few more things I discovered w/ update:
7. On the nav screen, you can no longer click the "i" symbol on the left to turn off the icons. Now, it brings up another menu w/ options to turn on/off icons or search for other POI's...not as easy as the previos version, but more options.
8. BLUETOOTH- this is totally redone. You can now select "Start Pairing" in the IDrive (this wasnt possible before) There is also 3-4 new menu options including "Help". Overall, the pairing is quicker on my phone, and the bt connection happens alot faster when you enter the vehicle.
9. The CD interface is totally changed. The CD does not continue playing when you shut off the vehicle anymore.
10. Voice Commands seem to work better.
11. After more time with the system, it appears overall speed is about the same, not faster as I stated above.
12. It appears the transmission shifts at different times than before the update...I need to spend more time driving to determione this as I drove it home during rush hour and it was hard to tell.
