 Auto aligned map
Map that is automatically aligned to the north.
For this a compass is needed (see Wishlist - Hardware: Digital compass)
When the Neo1973 is used for navigation, especially pedestrian navigation where the device isn't mounted, it is useful if it always shows the map so the north of the map always points to the north. When rotating the Neo1973 the map will rotate the other way to keep north pointing north.
If the Neo1973 is held with the face down the map will be mirrored. (or a star map will be shown :)
old discussion With an accelerometer it will be possible to make a compass.
Unfortunately, this is only possible with a compass, you cannot tell direction with an accelerometer. Gyroscopes won't work either because they ar relative so you still need a start point. If the phone is held vertical the accelerometers can't detect rotation, but even a 2D compass can't (if it's mounted flat), a 3D compass does.
Consider the phone held vertical with the two sensor lined up above each other.
If the phone is spun along the vertical axes, then the acceleration does not change at all, so you can't tell direction.
