I have a problem that maybe people here can help me with.

I have an OEM iGo nav system. From what I gather, Primo Nextgen.

The problem is that the Swedish TTS translation files are missing a few phrases. And that means when one of those phrases are going to be spoken, that whole subsystem stops working, and I don't get any more messages spoken. In my case warnings. So driving directions still work, but warning messages stop working.

Now, I've located which messages are missing, which files they are in and so on. But I seem to be failing in creating a new zip-file with these corrections. And I'm hoping maybe someone here can tell me how to create a new zip-file the system will be happy with.

The nav system uses an SD card. I'm using Unix (and/or MacOS). If people tell me I need Windows for this, I can probably dig something up, but it's not something I have ready.

If people want me to share anything, just let me know. And I'm a bit surprised to find such omissions in the language bits of TTS. Do they not have any customers speaking Swedish at all? Else I would have expected others to have reported this a long time ago.
