Hi All, I have a 2004 CL500 with the NTG1 command system, I do not have the eta facility in navigation so am assuming the firmware to be prior to the 06 update. Can someone tell me how and what code to use to get to the engineering menu on the display, and where or can I download the 06 firmware upgrade to get the eta facility?
Thanks for your anticipated help
