Any of you guys have the nav screen fail? I got in my car yesterday and it spazzed out hard. The next day I got in and it worked fine for a few hours and then pooped out again.

Everything works fine as far as the stereo functions, but I can not see anything on it. One second it is all there and the next the screen is scrambled. Is the led screen bad or is the whole unit defective?

Thanks for any help.
