Thanks Folks. I started reading the tutorials after I posted , Sorry I've been biting off more than I can chew lately , not enough time for everything.
I'll redo all this again and hope for the best.
Happy Holidays

Greetings, I just downloaded one of the maps to a mini sd card with the card plugged into the computer.
Now I am wanting to be able to view the map on the computer screen so I can see if it has some areas I wanted on it and then use the sd card in the GPS.
My problem is when I try to open the downloaded file it does just that and shows me a bunch of files instead of being able to view a map .
What am I missing here to be able to see the map on the computer with the sd card plugged into the computer.
Do I need a special program
Advise Please thanks frank camp
