...exterior mirrors? you know the mirrors which are outside how do i fold them....i know they are there i just don't know how to fold them... also how do i activate child lock?

also in map mode on my COMMAND system how do i get the road name with put zooming in??? i have a 2004- 2006 cd

also while route guidance how do i mute the gps volume while driving?

The owners manual is a plethora of knowledge about the car it will have the answers you need. Check the index.

Ok... I have an S500 but most should be the same. The mirror button on on the left where you adjust them. There should be 4 buttons and the little adjuster switch. Push in the buttons. One of them will cause your mirrors to fold in.
I believe that the child-lock is on the door. You can only reach it when the door is open.

I am afraid I don't understand the question about the zooming.

You push the mute button on your radio controls. You have to push it and hold it down while the gps is talking. If you do it while it is silent you will mute your radio.
I hope this helps. I am not sure if all of your stuff is the same as mine but it should be similar.
