From the wording of the press release it sounds like they view it as an optional add-on specifically for UK customers who want additional security:
Recently, evolving security threats, including the use of unauthorised electronic devices to bypass vehicle locking systems have become more prevalent in the UK. This is an industry-wide issue and Hyundai is providing appropriate responses in line with industry practices.
As part of the Company’s commitment to supporting our customers, we are able to offer a subsidised software and hardware upgrade for a customer contribution of £49.
