Default Adding adaptive cruise control 2021+ disco

I’m seeing videos online of using the GAP diagnostic tool to add ACC to new Defenders with just the tool - is this possible on non ACC equipped face lifted Disco 5’s?

Reached out to GAP and they confirmed the tool would activate ACC without any additional hardware

So your '21 has the ACC radar installed from the factory but not activated? Must be nice. I still have to wire mine in from scratch. The harness on the '18 doesn't even have the radar connector.
