I have been trying to download a Garmin Europe Map that I recently bought for my Garmin Edge 530 - I have followed every piece of advice I can find (removing the correct installed files, etc.) and STlLL it won't download - the device is connected to my laptop and it begins the download process from Garmin Express and then seems to drop out after 30 mins or so. I need a resolution to this problem urgently please Garmin...
