Okay, so for the past week I have noticed that I no longer get voice directions when I am using google maps for navigation. Instead I get a "Ding!" sound when I get to the next step on the direction list. I have tried to search high and wide for the navi/audio settings but nothing has helped. Something that is weird is that when I go into the 'Text-to-Speech' settings, and click 'Always use my settings', use Language 'American English', and go back, then back into the 'Text-to-Speech' settings, everything will revert back to how it was. It seems like my settings are not changing. Also, I have this app 'Navigation' installed as well as 'Maps', I can see the app 'Maps' in the market but I cant find 'Navigation.' When I open 'Navigation' it definitely has a different interface than 'Maps.' Maybe this could be the culprit? Any help would be appreciated.
