I just did this update and now for some reason my screen is completely Yellow.  While it matches the color of my Cub perfectly, I would like my sectional back :)  I have tried to update the Aviation databases and airport diagrams already.  Is there a way to delete the new software and then reinstall?  I did it wifi and updated the sd card directly thru I fly Connect as well.  No luck.  
Maybe my unit is special.....Instead of showing SUN for Sunday, it says SON for Sunday :)  
Anyways thanks for any info.
