There are a few videos on youtube that show how to access a secret menu on a C class. Basically you turn the key in position 2, then press the reset button 3 times. This way you can check the battery voltage, oil liters etc...
Is there something similar on the W220?

It's in the HVAC controls. Instructions are in the sticky a the top of is forum I believe.
Lots of stuff to review, nothing to adjust. The tach is kinda fun for the passenger I guess.

we can show a tach on the COMAND screen. ? how?

chpsk8

No , Not in the Comand, my HVAC controls are below the Comand screen, not sure where yours are.

W220S430

It is the same on the S-class.

yeah how do we show the tach/mph?? some benz's like my dads clk can show a digital reading mph

W220S430

There is an up and down button top/left of the steering wheel. Once in the regular menu showing the odometer and trip miles, click the down arrow button once

i wonder if its different for pre 2003 models or maybe my command is outdated? i just tried and it shows nothing

digital mph shows on the cluster of my '00. i never use it though since i prefer the stereo controls on my steering wheel.
