Tomtom one problems updating
": TTS, Text to Speech, is a function where detailed driving instructions are provided using computer voices. Part one are lane-use instructions for large intersections on screen, at the same location that is used for turn-left/right instructions.
Loquendo TTS requires a lot of working memory, and 32MB is not enough in most situations.
If you want N-American languages (English, French, and Spanish) you can try Vocalizer TTS. TTS requires a rather powerfull CPU, which is not present in the older models. This may work: Update: according to Dark Mireille, Loquendo fails to work because of a lock based on the device hardware. SE navcores generally provide Loquendo too "out of the box".
