I purchased an "unlock" service from bimmer guru, this will allow video from a dvd and an usb memory stick be displayed while the vehicle is in motion. But it requires a reboot of idrive. On other bmws, you only had to hold the volume button down until it reboots, bit that doesn't work on my M4. Anybody know how to reboot idrive on the M4? it's not in the manual
