GM ditching CarPlay could go bad, complain car dealers
(appleinsider.com)
This is a most excellent place for technology news and articles.
My Miata shipped without CarPlay. When Mazda added support it later they had to replace one USB port ($12 part) and an hour of labor.
They charged $350. I didn’t hesitate for a second. I haven’t met an OEM interface that didn’t make me want to stab myself in the eye.
