From the last week, my Garmin GPS unit is not showing the recent roads, routes, and maps, so I am not able to track the right route. I am using Garmin GPS unit for finding out the desired destinations exactly, so I am very comfortable with this Garmin GPS unit. I guess that it is the issue of Garmin GPS update. I am newly to this process, so I am not able to complete the process of Garmin GPS update. I don’t have much knowledge to update Garmin GPS unit in the proper ways. So I am asking from experienced users to share their experiences for this concern as soon as possible.
