Is this a change to Google Maps or part of the "tweeks" Motorola made to GB? There used to be a seperate volume control you could adjust through Google Maps, one that wasn't tied to Media Volume. I almost never had the volume turned up for navigation, especially if I was streaming music or had internet sports radio on. Now they're tied together so If I have music turned up, I get the navigation voice up too. Any chance I'm just missing a setting?
