Can I recalibrate my GPS on my 3G S ?

    Whenever I use maps or the newly released app, AT&T Navigator, my location is consistently displayed to be one block off whatever city street I am on. I am driving down highways, suburbs and the downtown area of Minneapolis (which only boasts a handful of really tall buildings that may impede the GPS signal) and I am always just a little bit off from my true location. Not true with my 3G.

    Also, my compass continually indicates I'm facing the wrong direction as well. If I'm facing south, it will indicate I'm facing South South East.

    Question 2: Should I be holding my compass perpendicular to my body and parallel to the ground or parallel to my body and perpendicular to the ground? Or maybe it doesn't matter.

    Thanks for any responses.

    Is your compass set to true north or magnetic north?

    My compass is all over the place when i'm driving. It shows me going along the road but its pointing a different direction. I have tried using both True North and Magnetic North (what is the difference?) and have also tried the wave motion calibrate as well as letting it calibrate on its own while driving. Neither works for me so the compass is currently useless to me. Anyone else having this trouble?

    I prefer True North. If you go with Magnetic North then you must calculate True North.
