I keep getting error messages 941 of 923. Does anyone know what these error numbers mean?
I quit my paid prescription to VZ Navigator for Google Maps because it was free and much better integrated with the other Google products.
That's sort of where I was going with this question as well - "Why are you paying for VZN NAV? Google Maps & Nav work so well."
Try clearing cache and data in the Play Store app. Menu -> Settings -> Applications -> All
If that does not work uninstall the Play Store update and try to update again.
