Hey !!!
Try using GARMIN EXPRESS UPDATER. I have been using GPS devices for a long time, whenever I go to places either it's a mountain trek, forest camp, or a road trip. Am always accompanied with garmin connect mobile app. The Garmin express experts not only helped me in updating the maps but also assisted me in other troubleshoot problems I faced. All my queries are resolved with a fruitful solution in no time whenever I faced any issue with my GPS device. It helped me a lot and will help you too. Do try to check out by yourself.
