This is not a GPS for all the time use. It is more for like a once in a while road trip use. This is because of the fact that you have to update it all of the time, and the only time it will tell you it is out of date is when Google has changed their maps completely, which happens once a year. Processing Speed Especially when on the go, it takes forever to figure out where you are and then to give you the correct route for where you need to go. Map Quality & Accuracy As long as you keep it updated every other month, the maps are fairly accurate. Ease of Use This GPS pretty much walks the user through how to use it with its two buttons to get you where you need to go.
