I did that as well (only changed voice file) but still no luck Im also shanging software version so it does start reprogram the nav unit but stops telling me that the voice files are not valid.
So my question was ; did you only rename the Swedish voice file and then replaced the english? Or did you change the voice file verison as well?
I might have a non valid voice file but the file ending as the same and coming from a origional VDO disc.
