The new RDX was scheduled to launch with both Android Auto and Apple CarPlay connectivity as standard features, but when the car rolls onto dealerships on June 1st, only Apple's smartphone mirroring and apps suite will be on the features list. What gives?

Parent company Honda offers both Android Auto and Apple CarPlay on its Android-based HondaLink display audio software. The new AcuraLink software is also Android-based, so it's not a stretch to assume Honda and Acura's systems share core software bones. This should have made porting features such as smartphone mirroring a snap. So why doesn't the 2019 Acura RDX offer Android Auto?
