Has anyone else tried saying "Redial"? Mine finally started working, but when I say "Redial", it confirms "Radial" as in radial tire and then redials. haha. But it works! Also, has anyone figured out how to get it to voice dial someone by their nickname? I have a couple of difficult names that it never hears correctly, and I can't get it to use the nickname feature. For instance, I have a ton of Dave's. One in particular has the last name of Csicsatski. (Pronounced Cha- Chost-Key) No matter how I spell it, it's a no go. I need to make my voice dial work smarter. Any voice dial ideas?
