Seeking to reduce driver distraction, BMW's 2010 models get simpler voice input for navigation and music entry. Developed by Nuance, the One-Shot Destination Entry feature lets the driver or passenger say the destination in a single phrase such as "1500 Pennsylvania Avenue, Washington, DC" rather than be prompted for the state then city then street then street number. The Music Search feature lets drivers search for music with voice commands, as with Ford's pioneering Sync system, which also uses Nuance voice input technology.

The features are on 2010 BMWs with the Harman Becker entertainment and navigation system and are offered both in the U.S. and Europe. BMW has offered voice input for years but of the traditional multi-step approach. It can be used jointly with BMW's iDrive controller system, meaning you can switch between voice entry and iDrive input. Typically if a car has both, you have to start and finish with one or the other but not both. The 2010 Mercedes-Benz S-Class gets One Shot Destination Entry also, but only on European models. According to Olaf Kappler, a Becker brand manager, "One-Shot Speech is a key part of our mission to bring a high-end, innovative user interface into the broader navigation consumer market that enables our customers to get to where they are going faster, and without the inherent dangers of manual entry while on the road." Research suggests simpler input reduces the risk of driver distraction but never eliminates it completely, just as using a handsfree headset for phone calls in the car reduces the risks inherent with one-handed driving but doesn't eliminate all distractions.
