This is how I resolved the issue on Magellan RM 5202-LM. # Use only Google Chrome browser (for Windows) # Register your product and account # Plug in your device to the computer using the USB cable provided # Login at https://www.smartgpseco.com/#sign/sign_in # After login you might see “No device detected” at left bottom corner (I did) # Click “Update” tab on top left side # You might see a notification to download a “Plugin” , click to download, note the location folder of the download # Log off from smartgpscom.com. # Close all the browser windows (very important) # Do not detach the GPS unit from the computer # Double click the downloaded plugin file to install (follow the steps suggested by the installation program) # Open the browser and re-login https://www.smartgpseco.com/#sign/sign_in # Now you should be able to see your device in left bottom corner # If your date of purchase is within three years, you should be able to update the maps # (Life time map upgrade is valid only up to three years from the date of purchase. Darn, I did not know this).
