When you updated your old Audio 20 system with the command system there are some control units that need to be coded to recognize the Command system.This has to be done with a dealers SDS machine and can run around an hours time in most cases.
On the newer model vehicles the Command then needs unlocked with the SDS machine at a dealer connected to their online programming system to program it to operate.If this is an older model usually you would see dashes or the word CODE on the display if it wants you to manually input a code and if it does not show this when turned on then this has to be programmed to operate in your model.
