:noway: The MapSource Beta v6.6 caused me a bit of stress today. I am luck to have more then one computer and I was able to resolve the problem on the other computer by using MapSource v6.3.
I have been using MapSource and it's updates for a few year now. My original Garmin Legend came with a serial port connector on the computer end and a "Garmin" type connector at the gps end.
I purchased a new Garmin GPSMap76C a few months ago and it came with different connectors on the gps to computer cord. On the gps side it has a mini usb connector, and a standard usb connector on the computer side. Along with the new gps came a CD with software updates for using the usb connectors. The problem is that after loading the usb software the computer and the old Legend gps would not marry up.
I dropped back to using a computer I have around for the grandkids which does not have Garmin's usb software loaded on it. The Legend upload and download data without a problem.
Today I tried MapSource Beta v6.6. It worked without a problem with the GPSMap76C. But I encountered problems with the Legend. It downloaded the maps, waypoints, tracks, and routes without problem. The problem came when I modified the mapset. I then tried loading the modified mapset on to the Legend. I received a message the software did not recognize the unit, the unit had no memory, and the unit was not connected to the computer.
I checked the Legend and found that the waypoints, routes, and tracks had been transferred but the maps had not. At that point I could not get my computer to recognize the Legend. I had to fall back on the one the grandkids use.
So is the problem with the software drivers? When updating MapSource for the USB drivers are the serial port drivers removed.? Is the problem with Beta v 6.6 or a combination of the drivers and the software?
As Dave in WV and I stated in an earlier post on Beta software, when you use it you are a test dummy. It is an at risk undertaking. In the past I have not had a problem using Garmin's beta software, this time I took a hit. So how do I fix my computer? Uninstall MapSource, re-install MapSource, and then update to release version 6.5.
