You can add many of the POI (point of interest) to your current Garmin by using
POI Factory . The POI are updated regularly. It may take some time to use figure out how to use
POI Loader. It works very well. One of my favorite POI's is
22,847 NORTH AMERICA CAMPGROUNDS (CSV) By Rivopom. It includes locations and phone numbers for each campground.
You can add all of your interest to the Extra's file in your Garmin.
I had to add a memory card to my Garmin to download all the POI's I added to my 2 560 DEZL Garmins.
6 years ago I bought both of them off
Garmin Factory Outlet. Have not had a problem with either one.
