## Discrepancy

(CAN) ON APPROACH, THE GPS430W UNITS INDICATED A DISTANCE OF 30 MILES WHICH THEN, SUDDENLY CHANGED TO AN INDICATED DISTANCE OF (2) TO (3) MILES CAUSING A LOSS OF CREW SITUATION AWARENESS. THE APPROACH WAS ABORTED. MFG WAS CONTACTED AND INFORMED OF THE PROBLEM. MFG REPLIED, STATING THE ERROR WAS CAUSED BY THE SOFTWARE VERSION IN USE WHICH WOULD BE CORRECTED ASAP. A COPY OF THE PILOT`S REPORT IS ENCLOSED. (TC NR 20071001008)
