I'm running 2.1 v3. Last night I was using navigation for a long trip while listening to the baseball game on MLB At Bat. I got an incoming call and the audio for the ballgame and the navigation voice kept going. My caller could hear the game and the GPS voice. Is there a setting that I need to change? The ballgame audio would stop automatically every time the navigation voice broke in as it is supposed to. But neither one stopped for a phone call. Also had a problem with the GPS signal being lost. Went on for hours with it unable to find the satellites. Restarting the phone fixed that.
