I'm not sure if that's a computation issue or if there is a built in delay between turns so they can all be shown on the screen. The map becomes unusable while it is stepping through turns.
It's a computation issue. The 1030+ is noticeably faster than the 1030 at calculating routes. The 1040 should be even faster. I think the 1030+ is faster than the 830.
The route calculation has to figure-out what roads/paths on the installed map the loaded track appears to be following. It does that by "walking" the track.
They seem to start at the beginning of the course. Starting at the closest point would be faster but I wonder how often that is done.
