Newbie here with a question, I was able to download the topo maps I wanted to my PC & have been able to put them on the GPS (thanks to the tutorials here), on the GPS in the Set Up, Map Information (Select Map), it shows the maps I've installed (NY topo, PA topo & NE topo). Question is, would I want to have each one enable or disabled? I'm not sure what the adavantages/disadvantages are.
Thanks in advance for your help.
