How can a GPS system sometimes guide you to the wrong location?
I just bought a GPS system and so far, it has been right on target, takingn me to places I've been to scared to venture out by myself alone. but someone told me that sometimes they can give you the wrong direction. how could a system that is globally navigated by satelite give you the wrong directions? help!

- it seems u got a cheap brand. its a computer device and it makes mistakes as we do. you need check the manufactor who made it. call the tech support.
- I haven't heard of a GPS pointing someone in the wrong direction. You say that so far your GPS has been right on target. My GPS tells me if it has lost satellite lock or something so it won't be accurate. It honestly sounds to me like your friend is trying to pull your leg or has been jerked around by somebody and doesn't know it and is just passing bad information. I have been out during overcast days and my GPS was not able to receive the satellites. But it didn't steer me wrong, it just said it couldn't display a position. If your GPS has satellite lock, it should be accurate to within a few feet.
- Because the road networks are developed by people and are based on interpretation and collection methods that are not always accurate. Think mapping error.
- It's the mapping software, not the GPS unit itself! Lesser quality units or older units have poor or out of date mapping. So many people think it's the unit that is the most important thing, however, it's the MAPS! If your maps are highly inaccurate or have few points of interest, you might be told to go places or take turns that don't exist. I have a Garmin 2610 and the maps are great. Once in a great while I will be told to go to a place, like a gas station that is out of business. However, the maps are updated every year and then when you update the info on the unit then that entry will be removed from your database. Hope this helps!
