I posted this up in the Escalade section and I didnt get much of a response. I have a 2003 escalade with navigation. Whenever i use the navigation the only time the voice guidance comes on is in the beggining and end of trip. I don't get the turn by turn guidance. The screen displays the route and turns no problem, just no voice telling me to make a left or a right or exit ahead.

I went through all the settings and everything is on. The volume for the voice guidance feature works when i change the level. I am at a loss with this. Anyone have some insight or had the same problem? Is there a diagnostic screen that I can get into to troubleshoot from? I don't want to take it to the dealer if its a simple fix. Any help would be appreciated!
