For those who had purchased a used car, delete the previous owner's idrive profile.

1. Settings
2. Profiles
3. Select the current profile in use (may have another name on it or look like ---)
4. Push the idrive dial to the right to bring up the "options" screen.
5. Scroll down to reset profile.
6. Takes a minute to do.
7. Turn the car off, wait 5-15 minutes for the idrive to completely turn itself off. If you are waiting in the car, make sure your seatbelt is not connected, or the idrive will not switch off.
8. Turn the car back on and go back to "Profiles" and select a "---".
9. Push the idrive dial to the right again, and select "rename profile".
10. Reconnect your phone, and start adding those shortcuts & other settings as preferred.

Before doing this my shortcuts and other settings would randomly reset themselves after a period of time and when using different keys to start the car.
After resetting and creating a new profile - every setting seems to save properly now.
