Step 4

Once you remove the CD changer you will have access to two bolts at the bottom of the COMAN head unit. These two bolts have Torx heads. You will need to get the bolts loose, they can not be removed completely. Unscrew them until they stop rotating. They are long and you will need to turn them over 30 turns to get the HU unlocked.  Pull out the HU and unplug the fiber optic cablem from the back of the COMAND A40/3 unit.

If you are replacing or upgrading with an OEM Mercedes-Benz head unit you can use a Mercedes-Benz Star Diagnostic C3 or C4 to retrive the settings from the old unit and transfer to the new unit. If  you don’t have Star Diag C3 or C4, you will need to set the new settings manually.
