2004 C320 SIDE MIRROR
I need to replace driver's side mirror, it turned amber and it is almost impossible to view thru it.
I found a replacement part, but there are two options, with o without "AUTOMATIC DIMMING"; how to know which option is the one I need without removing the bad one? wouldn't want to drive around without being able to view thru it, even though is damaged, thanks. ;-]#
