In the redesigned 2006 3-Series, BMW actually gives buyers a choice regarding iDrive, the multi-function control knob and colorful dashboard display that replaces proper controls for the stereo system. Dreaded by many, iDrive is installed in the new Three only when the optional navigation system is ordered. No nav, no iDrive. Hallelujah! We'll buy a map!

In the 2006 BMW 3-Series, the optional iDrive controls most stereo functions, secondary climate settings, the optional navigation system, and on-board communications features. Primary functions for the dual-zone automatic climate control are located on the dashboard, and BMW provides a CD slot with a knob for power and volume. We wish that we could get radio tuning and station pre-set controls in conjunction with iDrive, but it appears that this will remain a dream.

Voice-control is included with iDrive, accessed via a button grouped with satellite controls for the stereo on the steering wheel, and the 2006 BMW 3-Series is also compatible with Bluetooth-enabled cell phones (Paris Hilton would not think this is hot). The ability to issue voice commands, and perform stereo adjustments using the redundant controls, should help to reduce the amount of fumbling with the silver metal iDrive controller between the seats.

Cars without iDrive have conventional stereo and air conditioning controls mounted in the center of the dashboard between the shifter console and the vents, allowing the driver to concentrate on the point of owning a BMW: Driving.
