When using VZ navigator on my old phone I would hate it when I would get a call while navigating. It changes to a different screen, forces me to grab my phone and fumble with buttons while driving (not safe). As far as I new there was no way to disable phone calls with VZ Navigator. I have not gotten a call on my Droid yet while navigating, so I do not know what to expect. Anyone have any experience with this? Can I disable incoming calls during navigation? Is there an app for that?
