See and I think I'm only gg to look at the map and not listen to the voice audio directions.

That's what I do. I turned my bitch off. The GPS has first priority on my headset, but even with the volume turned all the way up, it's hard to make out what she is saying even when the music from the garmin is crystal clear. So I just silenced her ass.

The little bit I played with mine, I could hear the gps clear and loud

I'm wondering if it isn't best to just to turn her down. The break in the music should be enough to make me look at the screen.
