I think I am incline to agree with rondoan. I don't think that the system will announce street names when giving directions. I will however try the entries that rondoan mentioned. The entry TTS Pro is in the menu but it is greyed out so, I can't select it. I wonder if I can upgrade the IGo Primo software to make it work the way I want it too :-)

Thanks go to G-ulash and rondoan for their time and effort with this.
