I did a cursory search but couldn't find anything on this. Will I receive phone calls (8703e Sprint) while I have Telenav running?

I use Telenav mostly on long trips. If I have it providing me directions in the car and I get a phone call will I know? Can I take the call without losing the trip settings or will I have to restart Telenav after the call and hope I didn't miss a turn? Will Telenav tell me about an upcoming turn if I'm in a phone call?
