I think its a bug in ICS. I stream music with XiiaLive in my car and nav will mute the music the first time it speaks but after that she tries to speak over the music.
yeah ive been wondering if anyone else has this problem, it happens with the stock music app too, its pretty annoying to the point that i just dont even use navigation anymore if it isnt going to work right.
For me it doesn't pause the music but it lowers the volume of the music in the background so that the Navigation commands can be heard.
I would find the constant pausing and unpausing of the music to be highly annoying, especially since Navigation can constantly be cutting in. I like the current solution.
that's the problem. The music won't soften or anything. Navigation voice and music at the same volume. Do you have the verizon version? What music app do you use?
