Express v18.104.22.168, Windows 10. General settings: Express is running in the background and "launch when a Garmin device is detected" is selected. When the device is plugged into my computer, neither Windows nor Express detect it. I've tried installing the device on other computers with the latest Express and a good cable, and the device is not detected. When the GPS is running, it can sometimes reset on its own. Traffic advisories are no longer recieved. I noticed several weeks ago in my Favorites that a line contained Chinese characters. Can malware infect a device? Can a service center reinstall the software?
