I'm having an issue that has just developed sine the latest SP and it pertains to the Navigation Display Unit specifically the ETA of arrival at next active waypoint indicator. It's the reading in the top right corner of the NDU and looks like 0205.0z and it sits right above your ground speed readout. Just recently mine started spinning after IRS alignment for a lack of a better word. The numbers just keep spinning in ascending order and then repeats itself. I wish I knew how to upload a video of it to help explain. Then when you go to the FMC and go to the PROG page your ETAs on all legs do the same thing, just spins like a slot machine but doesn't stop. I have re-installed the program with the latest SP to no avail. This happens in both the 700 and 800. Any ideas?Chris Courtney
