Retro fit cruise control - Disco 4 commercial

[papa3]

Has anyone done it? General googling suggests it can be done but local LR tell me not.

The disco forum reckons its as simple(?) as adding the switches to the steering wheel and enabling the function using LR's diag.

Did it with a D3 and it's very simple. As you say, just change the steering wheel control and have it enabled by someone with the software. Follow the guides on the D3 forum and don't forget to disconnect the battery before you play with the airbag. You'll also need a little hook tool so you can unhook the airbag springs.
