The recently-introduced Eyes Free system by Apple can now be retrofitted into existing vehicles. It may not reflect Apple's idea perfectly, but it seems to work well enough, as seen in the video below.
The system promises to be integrated into vehicles from nine vehicle manufacturers and give drivers the ability to activate their Siri voice assistant on their iPhone 4S phones without taking their eyes off the road or their hands off the steering wheel. The aftermarket kit involves Dice Electronics' $300 MediaBridge device that ties into the car's infotainment system, according to CEOutlook.
The kit was said to be 10 months in development and is thus far only available for late model Audi, BMW, and Volkswagen vehicles. Pressing the voice button will activate Siri on the iPhone 4S over a Bluetooth connection, though the voice will be heard over the car's speakers.
The MediaBridge kit also adds iPod/iPhone controls to a factory radio, Bluetooth calling and music streaming, USB playback, and Livio Radio. Sirius is optional.
Factory integration of Eyes Free isn't due to come to cars for another 12 months or so.
