I had to hack Hyundai's website to keep my navigation and monitoring service. I bought it used 3 years old in 2016. At that point they had already removed the ability to purchase updated maps. Then this year I got an email saying the navigation and monitoring services would be unavailable for renewal. The renew UI was disabled, but I reverse engineered their API, crafted a request, and got a system error. To my surprise my subscription was renewed. There is no reason I can think of to discontinue these services other than to goad me into purchasing a new car.
