I have a Garmin 3790LMT GPS and BaseCamp (and other programs) isn't working for me Windows 10.
I have 2 Windows boxes here. A laptop running Windows 7, and a PC that was upgrade last weekend from Windows 7 to Windows 10. It was an upgrade, not a clean install.
After upgrading the PC to Windows 10 some of the Garmin programs no longer work. Everything still works on the Windows 7 laptop.
Garmin Express is the only Garmin program that still works great on Windows 10. BaseCamp, MapInstall, MapSource, and WebUpdater can no longer find the GPS on my PC. Each program searches but quickly reports no GPS found and prompts me to plug in the GPS. It is already plugged in. BaseCamp never lists a device to transfer to/from.
When I plug in the GPS, the GPS seems to initialize properly. I have no yellow exclamation marks in the Device Manager. The GPS shows in the Device Manager as GARMIN under the Portable Devices, and "Garmin nuvi Flash USB Device" and "Garmin nuvi SD Card USB Device" under Disk Drives. There is a drive letter assigned to the GPS and that shows up in the Windows Explorer. I can use the Explorer to peruse the contents of the GPS file system just like any other disk drive. It's obviously there so why can't BaseCamp see it?
I just can't understand why Garmin Express works perfectly with the GPS and none of the other programs can find it. It still works great on my Windows 7 laptop, but not my PC since I upgraded to Windows 10.
Note that my Windows 10 PC is currently on all released Windows 10 updates, including the updates issued 8/11/2015. I have also downloaded the latest available versions of BaseCamp 4.5.0, MapSource 6.16.3, and Garmin Express 4.1.5.0.
Please let me know if I can provide additional information.
