Narvelous, you said that you're still having a problem with it. Did you have the blank screen issue before you sent it in? The screen worked fine when it was updated.
We've been getting calls recently with the same issue. Most likely, it is due to the heat. Try unplugging the unit and taking it inside with you (I know it's a pain... I'm sorry!) where it's cool. Plug it back in when you start your truck and see if the screen is still an issue.
