I have Home V. 2.6.2.1586 and TT app 8.302 and map 830.2284 on a TT720. TT home has the computer voice download grayed out, and says that it doesn't work with my device. Plus, when I look at the voices thru Home, it shows the computer voices as not working with my device and that I should delete them to free up space, but they work just fine. Anyone have any ideas? Same problems?
