I have a G3 iBook running 10.2.8. I have upgraded my VPC6 to the most recent version. I bought MapSend Topo 3D a few weeks ago, and had no problem loading it. It runs fine, except the G3 is not capable of drawing the 3D . I am trying to figure out how to upload to the GPS (MagGold) without using a card. I do have one, in case I cannot.
Just my 2 cents.
