Supports hidden functions activation for three brands: for BMW, for VW, and for Benz. It covers common unactivated vehicle configurations (such as seat memory linking, ambient lighting customization, driving assistance enhancement mode, sport instrument cluster, etc.). The operation process is simple—by including function descriptions, illustrations, and precautions, the entry barrier is lowered, allowing even non-professional users to complete the operations with ease. An automatic backup and restore function is built in: the original vehicle data is backed up before any operation, and one-click recovery is available in case of anomalies, preventing vehicle function issues caused by misoperations.
