GM has been moving quickly to announce wide-ranging support for Apple's CarPlay and Google's Android Auto in recent weeks, and the automaker can add two more of its brands to the mix: Buick and GMC, both of which will start adding compatibility this year. CarPlay comes first, hitting the 2016 Buick LaCrosse and Regal alongside GMC's 2016 Canyon, Yukon, and Sierra; Android Auto will follow later. If that approach sounds familiar, it should — it's the same one that GM is employing with Chevrolet and Cadillac, both of which have already made their connected car announcements.
Not all automakers are sharing GM's fast and wide approach to CarPlay and Android Auto support: Toyota, for instance — which spars with Volkswagen and GM as one of the largest car companies in the world — has been taking a far more measured approach. It recently announced that it's investigating the use of SmartDeviceLink, the open-source version of Ford's AppLink, to let mobile apps to talk to the dashboard. That doesn't preclude it from adopting Apple's and Google's platforms, of course, but the company has shown precious little hustle to big the way GM has. (Likewise, Ford has been moving pretty cautiously.)
