Hello all. My husband delivers coffee and his employer doesn't organize his deliveries in any order. He manually must plus in addresses one at a time into his GPS AFTER he's organized the route slips by town. He would love to just be able to plug in all addresses & cities and let the GPS or his home computer put the route in order for the best use of his delivery time. Is there a software out there we could purcchase for him to do this?
