I am having the same problem with VZ Navigator
I have been having this issue off and on for about a week. I called verizon and was told to delete and reinstall the program. I did this and it still is happening. I called verizon yesterday on the way to a destination that I needed VZ navigator for. After 45 minutes on the phone, they told me that they had elevated it to the next level due to uninstalling and reinstalling it again while on the phone with them it still didn't get it to work. They said that it was not showing up correctly in their system even after they put it into the system on their end. I still have not heard from them. I have Endomondo installed, but I have been running it for 3 weeks and this has been only happening for the last week.
I am going to try the "test" and see if anything happens. If I hear back from VZ, I will update.
