I installed it. No issues so far. I am disappointed by the route planner though. It literally only just adds chargers as waypoints to your route; it doesn't display expected charge times or arrival SoCs, nor does it automatically reroute and pick different chargers based on the new route like the unofficial engineering mode version did.
Hyundai says it's the third-largest automaker in the world. It's quite disappointing that they can't seem to get this right.
