I have version NextGen 9.19.5.584533 on Zenec Z-E2015 run.
Everything functions really, only the voice output does not go.
Z-E2015 has original the version 9.6.5.430095, there functions the voice output.
Which file is different there? ( data.zip )
Or is it an entry in the NavigationReal.exe? ( coredll.dll )
