BMW and a few other automakers have already implemented a system where one could search for directions and directly upload them to their car. Mercedes recently decided it was high time to add this feature to it's lineup of vehicles. Anyone buying the '07 S-Class, CL-Class, and '08 C-Class vehicles equipped with the Multimedia Package and Navigation System will be able to use the service for no additional charge. What sets this service apart from the competition, however, is the ability for relatives/friends to upload a map (to their house, for example) while you are on the road. However, for the service to actually work, customers need to buy a subscription to the Mercedes' Tele Aid System, which is free the first year.
