We have a GPS76 connected to a Dell laptop computer running nRoute V 2.7.6. It will Auto Detect the GPS, however, it will not transfer GPS tracking data. I can transfer data (waypoints, routes) back and forth between my Mapsource program and my GPS76. When I run my nRoute the program cycles through "Attempting connection to GPS" "Searching for Satellites" and Connection Broken". I had this problem when in the past when I set up my original Dell. At that time Garmin customer support helped resolve it. Bought a newer Dell and had the same problem. This time Garmin will not give customer support for nRoute and I do not remember how the problem was resolved the first time. Anyone have suggestions?

How is the GPS76 connected to the laptop? Is it serial or USB?
