The German auto maker received word from Apple prior to CES, preventing the company from showing off wireless CarPlay. “We wanted to demonstrate wireless CarPlay and the owner of CarPlay technology didn’t allow us to,” said Volkmar Tannerberger head of electrical and electronic development at Volkswagen.
Apparently, Volkswagen planned to show off CarPlay's wireless capabilities. Currently an iPhone must be connected to a vehicle via USB to use CarPlay, however wireless CarPlay is in the works.
