Thread: Igo nextgen and alpine w987d

Problem with Forum yesterday, it fell just as I typed the answer...

TTS pro ux by Zervdim is included in Toyota package (you have downloaded it already)
You must do it by yourself - add one by one ux, and you will find which one is problematic...

One thing is interesting. One colleague configured his own package, which contains twice as much ux files, over 140 lycs, gfx, and TTS, and works without problems on his unit.
I suppose though you're wrong somewhere in adding files.

Try with English language only. Or use those one that come with unit software
One more thing I can do for you, try this ux package:

Spoiler: ux pack

Inside are two TTS ux files, try first with one (disable the other), then vice versa.
