IHS recent reviewed the latest BMW 750Li xDrive with the new iDrive 4.2 infotainment system. Loaded with telematics and Bluetooth features, drivers can connect their iPhones to access the BMW Connected App to check their Facebook and Twitter feeds, or listen to internet radio. Other telematics features include Wiki Local, Google Local Search and Street View. On top of all of that, there is a 6-DVD changer in the dash that plays through a 16 speaker, 1,200 watt, Bang & Olufsen surround sound stereo. Rear seat occupants even get their own iDrive screens and interface.
