Easy GPS calculates the area of any Garmin GPS track or route, making it a perfect tool for calculating acreage on your farm, ranch, or business.
Fixed issue where the right-click context menu was not always getting updated to display the correct options to the user in certain situations.
The FIRST Nuvi is about 6 months older than the second. BTW: I know these 660's are dated, however I am very happy with them.
The SECOND 660 has extras such as traffic, Safety Camera and a POI data base for vertical clearance. I even did a little housecleaning on the FIRST Nuvi, trashing the MINIMUMl amount of unnecessary data that I could find.
Just one click converts all of your Garmin data between any format or datum (WGS84, NAD27, NAD83, and dozens more).
Backup your Garmin nüvi 660 GPS waypoints, routes, and tracks after each outing, so your GPS data is always safe on your computer.
