Today I confirmed my suspicions about Copilot Live - an incoming call causes navigation to stop. Upon completing the phone call, the app loads - not where it left off, but from scratch - and then calculates the route from your current position. Is this behavior unique to my installation? Or the Motorola Droid? Edit: I should add that NDrive also stops upon an incoming call, but does not automatically resume afterwards. I'm starting to wonder if this is some remnant of development for some non-multitasking phone OS that I won't name.
