Good afternoon.
I would like to thank you all for getting involved in my journey of solving the problem with my Avic-F70tv.
I solved the problem today, at the GPS Club Forum I talked to a guy and he told me to run a script to remove the read-only attribute from my CM's TTS folder, he made the script and sent me, I ran the CM and solved the problems with the TTS voices.

If you have a Pioneer Media Center and have the same problem as me, I can make the script available!
Mine is an Avic-F70tv.
