I see several previous posts on this topic and I have tried every single suggestion. I cannot tell you how many times I have uninstalled, turned off my computer, and reinstalled every aspect of my Garmin install including Garmin USB Drivers, Garmin Express, and Garmin Basecamp. I also manually deleted the leftover user\appdata turds before reinstalling and am still unable to use these commands; no dialog box pops up.
I'm using Windows 10, current version. I AM able to create a NEW TRIP so I'm not totally out of commission but this issue is having me pulling out my hair! Yes, I may be OCD and cannot accept defeat...
