  1. Hi,
    Do you really have the NTG 2.5 Comand secreat code. Does it work. I have installed the NTG 2.5 Comand in my car
    Mercedes E200K, W211 and looking for help to activate the comand, Aux Video input, Rear monitor entertainment and Video in motion. The radio, Bluetooth, Rearview camera are all working perfectly.

    Best Regards.

  2. I have a 2009 Mercedes E350 wagon with a NTG 2.5 Comand and would like to install a backup camera. Are the codes available to reprogram the Comand to ad the Backup option. I beleive it is option 218.
