When I switch to North up, the jumping does subside, but then the cursor jumps around. It still doesn't help when in the compass mode. I should be able to use the device in any mode I want without this happening, don't you agree?
My point of the post is that there seems to be a problem with the new software, at least in my unit.
Does your unit do this when in Track up mode with the latest software or is the display nice and steady?
