Hi,
There may be an issue with the alpha keys being interpreted as numeric on the MFD keypad under certain circumstances.
Steps to reproduce
1. Battery on
2. Enter on the MFD
3. Direct button on the MFD key pad
4. If I select "A" for the first digit I get a numeric "1", "B" a numeric "2" and so on up to "I". Once you get to the "J" key you get "A" but after that things get a little less predictable.
From what I've seen so far this only seems to affect the first digit of a waypoint.
Work around cursor back with the outer FMS knob and overwrite.
Regards
