Bring SP2610 to the PC, connect the SP2610 to power and USB port using the adapter & cable provided with the SP2610.
Start MapSource and load the desired file.
Click on the icon with an arrow pointing to the GPS.
It takes a few seconds to find the SP2610 & then you get a menu to select maps, waypoints, routes, tracks.
Select what you want and click on transfer (or send, I forget & GPS is in the truck)
