WARNING for E60/ E90/ F10/ ... style HeadUnits!
There have been reports of bootloops. The issiue was tracked down to the stock launcher not beeing set as the default launcher.
Therefore it is NOT recommended to install the launcher on SD450/ AC8227L units.
This issiue also appears whith other third party launchers and is thus not only restricted to the iDrive Launcher.
If you are experiancing such an bootloop, don't panic. You have to get into the recovery-mode of your unit and reset it to factory settings. Please contact your reseller or refer to your user manual for specific instructions.
So far I only recommend installing the launcher on SD625 or PX6 devices.
Note: This does not apply for E39/ E46/ E38/ E53/... units.
