How to add Polish language to a Navman (GPS)?

I have a Navman GPS which I bought and use in the UK.

To make life a bit easier for my Polish girlfriend I would like to put Polish on it.

Has anyone been able to add Polish to a Navman?

hmm.. my garmin nuvi has it built in.. but i am guessing you could go to the manufacturer's website and see if they have that option.

You would think so, but I can't find it as a separate option.

there is no language options in tools or settings menus?

Yes, but the list was written by some bloke in NATO I guess :-)

Some voice options:
English - UK
English - US
French
Spanish
Italian
Swedish
etc, etc

All the traditionally 'Western' European languages.

Even if I buy the Eastern European map 'pack' at £39, I wouldn't assume it would have Polish as a system language, as they don't even appear to sell Navman in Poland (or any other Eastern European country for that matter)

I know that 3rd parties do alternative voices, such as John Cleese who rants "OK, don't listen to me then! Do it your own way" when you don't follow the instructions. So I wondered if there were 3rd parties doing language packs. Possibly not.

Thanks for that.

good luck
