Hi, I'm new here and I'm in need of some help. I have Garmin Bluechart V9.5 (unlocked) loaded on a Windows 7 machine and when I open it in Mapsource (6.16.3.0) I don't see any depths or contours. I also have Homeport loaded on the same machine. Am I doing some thing wrong? I'd like to be able to use this with my GPSmap 76S. Thanks, Jim
