Google today unveiled Android Auto, which will let users connect their Android phones to a car and cast the Android experience to a vehicle's touch screen.

During a demo at Google I/O in San Francisco, a Google employee connected his Android phone to the car, which synced the device to the touch screen. He could then control alerts using the steering wheel buttons, the display, or the car's knobs.

The first thing the driver sees is an overview screen with things like reminders, contacts, and music. One tap and he's navigating to a destination or listening to music.

Using the "OK Google" command, meanwhile, the driver can also ask the car questions, whether it's driving directions or hours of operation for a nearby museum.

Android Auto comes out of the Open Automotive Alliance (OAA), a collaboration between Google, Audi, GM, Honda, Hyundai, and Nvidia designed to accelerate in-car tech innovation. Today, the OAA added a number of new members (above), including Volvo, Volkswagen, FIAT Chrysler, Mazda, Mitsubishi, Nissan, Subaru, and more.

Google said that over 25 car brands have signed up to ship Android Auto, and the first cars with it installed will roll out of dealer lots by year's end.

Google is also releasing an Android Auto SDK "soon," with full APIs for audio and messaging apps, the company said at I/O. The Android Auto experience will be available to users with public launch of the next-gen Android, dubbed L-release, later this year.

Google rival Apple has a similar offering, dubbed CarPlay. For more, check out PCMag's hands on with CarPlay from WWDC earlier this month.
