I decided to try Polar Navy based on your suggestion. I downloaded the free 30 trial installed it and plugged the Garmin 76cx into the usb port. The instructions say: Right click on PolarCOM tray icon and select Configure menu option. Well, there is no tray icon (Blue Globe) and I cannot open the Configure menu! Even with the shift/alt/C, it won't open. So....here I go again!
