Simple navigation system and method

A simple navigation system installed in a motor vehicle comprising:

• a GPS (global positioning system) module adapted to calculate the information of the current position of said motor vehicle;
• memory means, said memory means having stored therein a simple navigation information which comprising at least two position parameters, a pair of predetermined 2D (two-dimensional) grid number, and multiple pairs of 2D (two-dimensional) indexes arranged in order;
• processor means adapted to read said at least two position parameters from said memory means and to define a virtual 2D (two-dimensional) grillwork by means of said at least two position parameters, to read said pair of 2D grid number from said memory means and to equally divide said 2D grillwork into a plurality of 2D (two-dimensional) grids each having a respective reference point position and a respective pair of 2D index defined subject to a 2D array rule, to fetch the information of the current position of said motor vehicle from said GPS module and to compare the information of the current position of said motor vehicle to the reference point positions of said 2D grids so as to calculate the pair of 2D index of a current grid corresponding to the current position of said motor vehicle, and to produce a guidance information by comparing the pair of 2D index of the current grid of the current position of said motor vehicle to the pairs of 2D indexes of multiple traveling grids stored in said memory means, said traveling grids corresponding to the 2D grids including at least one traveling route proceeding from a starting point to a destination point;
• and
• output means adapted to output said guidance information.
