To dream of a GPS device symbolizes your ability to accept criticism.
The meaning depends on what you did in your dream, after you got the directions.
If you tried to follow the directions, this means you are able to see yourself clearly and listen to the opinions of others.
If you didn’t, you have a problem dealing with authority. Perhaps you are overly sensitive.
If you dreamed that the GPS wasn’t working correctly, or was broken, you may be feeling worried and insecure about the path you are taking in life. You may also be missing somebody.
