Hello John, The app shouldn't work while on a phone call, but sometimes it does which is an apple bug, since all background sound should be suppressed while on a phone call. If you haven't upgraded to iOS 7 you will only hear the sound effects in the background for route upcoming turns, arriving at your destination etc. Only under iOS 7 will the app give you voice output while in the background. The app does announce intersections as well while in the background as well as POIs and route turns, so I am not sure what you are referring to unless you have not upgraded your phone to iOS7. Thanks.

I had occasion to use the background mode last week to try it out during a walk and like the fact that it cuts out the amount of information you receive, leaving in the upcoming intersection which is the most valuable info at least for me. Does this mode work while on a phone call?
