One of the advantages that comes with the Mercedes navigation system is that the car's download manager automatically checks for available updates with a Garmin Map Pilot SD card. All of the updates are free.
The Garmin system lets drivers avoid asking for directions and helps drivers save time with optimum route calculation and ready information on points of interest in the local area. The system lets drivers choose the shortest route as well, which can help save fuel and money. The navigational display is designed to avoid one-way roads and to find fuel stations quickly when refueling is needed.
