In rare instances, the IFD's datablocks on the right side in the MAP page will be scrolled to the bottom after startup, which requires the pilot to manually scroll them back to the top. 

There is a simple workaround to prevent this from happening:

1. Go to the Datablock Setup page
2. Touch scroll the datablocks on the right side to the top
3. Touch the top right side datablock to select it
4. Using either touch or inner knob, change the selected datablock to anything else
5. Using either touch or inner knob, change the selected datablock back to what you want
6. Wait a second or two and then cycle power
