Thank you Pietu for the new .reg code. As you thought I have 64 bit Windows. I managed to get the maps to MapSource with that new .reg file. For a reason or another I don’t see maps as detailed in my GPS (Oregon 450) as in MapSource. I have chosen Most as a detail level in GPS but there’s still less details like road names or water depths. I would insert an image to this post to illustrate the differences but this is only just my 4th post. My post count must be 10 or greater to do that.
