What does an F service in 2006 e350 4Matic include? And my CD Changer and Navigation is acting really really slow. For example, if I try to go from one CD to the next, it takes eternity, and also, when I enter new address in my Navigation, the page changes very slowly. Is that due to the battery or is it a specific problem with the Command system? Thanks

You need to access the service menu in the instrument cluster display , to get this the main screen must be showing mileage screen or outside temp , turn ignition to position 1 , then press the small black stalk at the side of the cluster 3 times , the display will now show UB12 v , using the up arrow on the steering wheel cycle through menus until it displays service menu , use the ' - ' button on the steering wheel to come down to items , now press the page forward button on the wheel this should now show service items with numbers that correspond to items in the service book

PS: Read your owners manual again

in 2006 e350 4matic, does the main battery that is in the trunk serve the command system and the CD Changer?
