"Lexus says that new software will be installed on the Lexus Multimedia System to add the CarPlay feature, and a Lexus dealer is required to install the update."
If they are required to install it then why should anyone pay money for this? Not to mention it's CarPlay.. this should absolutely be universal. Such a scam!
Required as in "only a dealer can do it", not that the dealer is "obligated to do it".
