Yes, so i turned on the switch which lights up and then i got up to speed and pressed the set + and i let go of the accelerator but nothing happened. Was expecting it to maintain that speed or at least feel some kind of trottle response ?

so i retrofitted the cruise control on my 03 disco. all looked fine and i can see on nanocom that the switch works. however the Set + button doesnt seem to be doing anything? what am i misisng? how can i check if the switch is maybe faulty?
