Just used this app on my iPhone to make the following changes:
-Auto-Fold Mirrors on comfort touch lock/unlock
-Windows/Mirrors/Sunroof open/close with FOB
-Legal disclaimer removal
-Ambient lighting 100%
-DRL 100% at all times
-Digital Speedometer
-Show current gear in dash
-M Performance iDrive Startup
-M Performance BC startup
-Door handle lights on during reverse
I would highly recommend this app to anyone. It was super easy to utilize and backs up your settings in case you need to revert your changes.
Probably the best $30 (App) and $12 (OBDII Adapter) spent!
