I have become very frustrated, when my GPS unit is not working properly. I am using Garmin GPS unit for tracking the correct routes and desired destinations. With the assistance of the global positioning system, I can find out the right destination comfortably. But from a few days, my GPS unit is not working in the right ways. Hence, I have become more worried. I don’t have the ideas to sort out Garmin GPS unit not working issue. I hope that it can be an actual reason of Garmin update. Therefore, I am asking from trained technicians to recommend the fast ways to resolve GPS unit not working error.
