Mmm… I’ve not read that as an issue…
It’s strange that you are noticing that, because from the file list you sent before there are no voice packages for Sync3 itself, only voice for NAV.
Your Sync3 voice package is current as well.
The MEM_ERR03 error is for lack of space for processing the files, which can happen for big files as EU maps being processed in a bulk way. Your unit has 10GB of free space which may seem like a lot, but it’s not, really.
The only thing I would try is performing a Master Reset.
Will that solve your issue with voice control?, hard to know, really, because the voice package has not been changed based on the file list you sent before. But it does not hurt to try.
