Press and hold the phone button until you enter the setup menu.

The first question you will be asked is if you want to change the language.

You will have the choice of English, French or Spanish.

Hope this helps,

There is a software calibration available at your Cadillac dealer to reprogram the module for French commands.
You cannot do it yourself it has to be done with a special programming tool and a Techline terminal.
Is that what you mean?
I think they do it mainly for French Canadian customers.
