I have Garmin Map source and their Blue chart on the laptop. Since I got the Garmin 545 chart plotter with the Vision card of my area, I haven't turned on the laptop!! ( 2 years ago)
Ron, I have a Garmin GPSMap76Cx, as I noted in the first post which is in the link that started this topic. I also have the MapSource software with the Garmin.
The purpose of this topic is to investigate the options available on a laptop, since I just got one (!) and am interested in what I can do with it. I also don't feel the need to get into the advantages and disadvantages of laptops vs. handhelds vs. chartplotters. Been there, done that.
I'm ONLY interested laptop use with the Offshore Navigator Lite MapTech software using the free NOAA charts and a GPS USB dongle to the laptop. Separate from the Garmin handheld and its own proprietary MapSource software.
From what I'm beginning to understand, from the great replies to this topic and the one on co.com, as well as the MapTech updates I've linked above, it appears that the Garmin GPS can actually be used directly with the Offshore Navigator Lite MapTech software by plugging in the Garmin 76Cx handheld USB output.
Even so, that's NOT what I'm interested in because I want the Garmin handheld in the cockpit. I'm interested in using the GPS USB puck connected to the laptop as another source of information and planning with the free NOAA charts on the Offshore Navigator Lite software.
Babel should let me switch back and forth quite easily.
The more I get into this, the more options appear to be available.
Thanks again to you all. Keep 'em comin'.
