G'day,
I have found a thread that has been going for 4 year regarding this issue and looking through that one, I still don't have an answer. The answer at some seems to be to contact application support which still hasn't given any of us the answers.
I have a ZUMO390Lm and Basecamp 4.3.5 (the lastest I think) running on Win 8.1 good PC and the bottom line is that the map is redrawing VERY slowly and sometimes just seems to freeze. This happens with zooming, panning heck anything you do that need to refresh the map is just grinding it to a halt. At this point it becomes unusable.
Any ideas ??
Thanks
Joe
