This exclusive activation function is tailor-made for the Land Rover Defender Configurable Modes L663. It unlocks a dual-function memory authority, which intelligently and accurately saves your customized settings for Auto Stop/Start and Driver Assist systems from the last drive. It completely improves the rigid factory logic that forces full system resets after every vehicle restart. This upgrade perfectly solves the common factory drawback that all personalized settings are cleared after ignition, eliminating the need for repeated manual readjustments and greatly simplifying daily vehicle operations while enhancing overall driving convenience.
