Is there a way to add languages beyond default ones to Cadillac XT5/XT4 radio system?

I can activate different languages if the Cadillac XT5/XT4 uses an HMI 2.5 module.

Thanks for clarifying. If I understand correctly, HMI 2.5 was in early XT5 models (2017-18). Do you have solutions for newer models without HMI 2.5? Also, for models with 2.5, can I get the Hebrew language file via USB, or is it DPS only?

No, I don't have a solution for the newer models. Maybe someone on here can help with that. The languages are activated in the HMI 2.5 calibration files and then programmed using DPS. I don't have a USB solution.

maybe someone in the group has a solution for changing the language in the multimedia system for Cadillac Escalade, Chevrolet Silverado 2024, or Hummer EV?
