The new Comand system in the 2007 Mercedes-Benz S-Class is a huge improvement over the confusing setup in the previous car, and though it takes cues from BMW’s iDrive arrangement, it’s much more intuitive to use if not easier. Why these German luxury car manufacturers see fit to provide a full array of climate control hard keys on the dash but integrate stereo functions with the navigation system is beyond me. Mercedes also improves on BMW design with a better-integrated CD changer that is hidden in the center of the instrument panel behind a door, and includes a slot for media cards. If you can remember the correct menu, Mercedes makes it very easy to set radio preferences, program the navigation system, cancel route guidance, and zoom the map. I was able to make this car function without looking at the owner’s manual, which means the technology is getting easier or I’m acclimating to it better.
