My Venture HC is a bit slow to refresh. If I load only a small area of the NY topo I'm using will it refresh faster? Thanks, C.
Don't own one of those, but I suspect that zooming in or reducing detail level would be more likely to improve screen re-draws. Let us know what works.
I took everything out except one quadrant and it didn't help the redraw speed. At least not a lot. C.
Your GPS is a bottom of the line, older model so I suspect "it is what it is".
As suggested, set map detail lower and see if that helps. You can also turn on de-clutter. Setting the unit for North-up instead of Track-up will also help since less re-drawing is needed as you move.
