Goodmans GNAV10- language

[onlybarca]

I've bought a new Goodmans GNAV10 navigation unit with Destinator OP installed on it. I've installed speed cameras today but another think important for me is to change the language! There are many languages in settings but there is no Polish... Is it possible to download and install Polish language on it? Maybe there is a patch to add some languages? Can someone help me? I'd like to have Polish text and voice commands as I am not good in English...

Thanks so much
