This will acutally be for my father. He feels more comfortable with it in his cars as well. I am like you, have the trails in my head, but if he makes a trip with his friends, he does not have that knowledge.
I would not need the card...I would just pick up the greatlakes sled map upgrade.
If you could post a pic with all the goodies and the box, that would be great. This would be a gift for Christmas. So I am not sure about buying a used vs a new with the warranty...
Thanks
