Hello. My name is***** can help you with your question.
The key to getting this working is to get Garmin express to startup and not freeze when you launch it. What operating system are you running Garmin express on? If you're running on Windows what I would do is run the startup configuration and disable anything that you don't need immediately – you do that by clicking on your start menu and then run and then typing msconfig and then enter. Uncheck anything here that you do not need starting up with the computer. Then try running Garmin express again to see if you can get it running. If it will not run just by clicking on the icon, right-click on the icon and select run as administrator. If it still doesn't work, then you may have to uninstall Garmin express and then reinstall it. It should not really be possible to only have a small part of France on the maps so I suspect that your map update has yet to complete on the device.
