If I use the Tomtom 540 WTE to go from place A to place B, and then turn it off, and the next day start from place A to D, it thinks I am going from B to D and takes several minutes of driving before it recognizes where I am. Is there a way to tell the GPS to reset and look for a new location? And is there a way to tell it to make the current location a favorite destination (if I don't know the street address, or if the street address covers the entire mall).
