Hello everyone.
First of all, I want to apologize if there is already any help topic on the same subject here. If so, thank you for pointing it out.

I come to ask you for help that I know you can do.
Originally, I had a CD30 MP3 + IDB in my van. I switched to a NAVI CD70 + CID (2 lines).
The CD70 version / year is 2004. I updated it to 10.10.2007.
I only have 8 languages ​​to choose from. I have a file with the name "MO5712_plus_CZ_SK_PL_PT_langs_for_PC5400-PC5500" that contains the language in PT-PT (among others more). But how do I update the language of the CD70 menus and navigation voices?

Thank you very much for your help because I wanted to put everything in PT-PT.

Greetings to all.
