In addition to the Music Server, the HDD system also tracks your vehicle's maintenance, and provides a personal calendar with message playback function. It even tracks weather conditions — from barometric pressure to ambient temperature - and can provide you with the latitude and longitude of your vehicle's position. It also includes the following features:

• Maintenance recorder including oil changes, oil, air, and fuel filter changes, tire rotation, and brake service.
• Customer ETACS (Electronic Total Automation Control System) settings for lighting, door locks, and windshield wipers.
• Calendar function.
• Trip data.
• Environmental data.
