Sometimes when I have a destination set and as the voice is saying something I will make it louder or lower with the volume up or down button. 99% of time it goes back to the stereo volume control after the navi prompt stops. The other times it sticks on the navi volume, so if I make it louder or lower it is raising the navi volume up or down and will not go back to the stereo volume.

to fix it, I go into the settings directly on screen for volumes and make the navi louder or lower once it goes back to the normal audio volume controls.

Anyone else see anything like this?

 

not mine, maybe when ur changing the volume, u keep changing it as it is switching from navi to stereo?
