A client of mine also has an Eris and I was helping her get her navigation system set up and teach her how to use it. I wanted to put the google navigator icon (the blue arrow) on her home screen but could not find it anywhere in her apps. I did find the google navigation (map icon) app and set that up for her. So, my questions are: What is the difference between the two? How come I couldn't find the navigator app on her phone (on mine, it's under "programs")?
