This consists
Adapter loom to convert main wiring harness between Audio-20-CD and Comand NTG2.5.

Bluetooth antenna.

(pictures coming soon)

Please note that once you install COMAND NTG2.5 in a W211/W219 the CD compartment drawer will no longer open. We suggest you remove the CD changer before this and sell it. The currrent phone system also becomes redundant.

Also, if your car has Harmon Kardon, then you will have to replace the Harmon Kardon amplifier to install COMAND NTG2.5.

If your car does not have linguatronic, you may like to add the linguatronic lever as the NTG2.5 units include linguatronic.
