Is there a way once you are in a location a button you can hit that will save that location in the GPS and then when you want to return there you can just go to the name you designated for that location and it will give you directions from where you are??

When on the map screen, hit the touchscreen and it will bring up like six buttons on the right side of the screen. Hit the one that looks like a paper and pencil and it will add your location to your address book. You can then name it whatever you want
