I want to keep myself safe and secure, while traveling. So I want to use Garmin GPS devices so that I can travel anywhere around the world. Sometimes, one or many times, I go on mountainous and hilly areas, so I face some challenges. So I want to use Garmin GPS devices rightly. I have little more knowledge for Garmin updates. How do I connect my Garmin GPS to my computer system? I don’t have right answers for these questions. Can you guide me step by step for this difficulty?
