When it was first announced, Hyundai mentioned that the upgrade to CarPlay would be a simple download for the owners of 2015 or 2016 models. Unfortunately for those who were expecting it, something has changed since the original announcement as it will no longer be a free upgrade.
In order to get the CarPlay functionality, Sonata owners will need to purchase a special SD card that will upgrade their system. So far there has been no word on how much the SD card will cost. It will be far less than a brand new CarPlay-compatible unit though, I’m sure.
While we don’t know exactly when the upgrade is due out, it should be out sometime in Q1 of next year.
