After I installed my music on the Captivate and plugged the video cable into the factory screen of my car (Pontiac G8). I wanted to see how everything including nav on the screen and it looked pretty dam good. I fired up the music player and put it in the background and fired up Google Nav. I entered a destination and every time it spoke a direction, the music paused then started playing after the directions. I was wondering about this from day one and I found out and Im happy about it.
