  • the log for the USB you used
  • a fresh interrogator log output

Am sorry I do not know what I did with them.
At my age am lucky if I remember my name.
So am I screwed, wouldn’t be the first time?
thank you

Mmm… I’m not so sure how to respond to that.

Can you create an interrogator log and share the results?.

Also, this “voice” issue you mentioned, is new to 3.4?, or did you experience it before as well?.

So basically everything works fine except the nav voice?

It’s been a few days, has it corrected itself?

Reload the voice files for NAV.

Are you using CarPlay or Android Auto?
