The voice on my navigation system on my longhorn is so quiet but I cant figure out how to turn it up! I've looked at the owners manual, but they dont talk about it. I am just trying to make the voice louder so that I can hear it while I'm driving.

Thanks for the help!

 

I can't remember how to do it but have you looked in the owners manual on the CD that came with the truck? I think it has more info than the book form of the manual.

 

Go to Navigation then setttings and there is a option for the voice or volume .You can adjust it more to passenger or driver side
