I'm still running 2.000 and have made a number of minor modifications (skins, boot screen, map updates, etc.) over the years. However, I just noticed that I have no voice when using the navigation (I also don't get the voice nag when I go over the speed limit). I know that sound works on the device since I still hear the beeps and the iPod works on it. Any ideas what it could be and is it worth it for me to upgrade to 3.0 (it's only $60). Thanks!
