Mike,
I updated the firmware. Still have the same problem. I entered a route YPEF - YMNG - YSHT- YTOC. The first leg is 38.7 nm. on the map page, DIST NEXT is shown as 38.7nm. ETE is shown at 22.00. NEXT WPT is MNG. When I get to YMNG, DIST NEXT has run down to 0 nm and ETE to 0.00. Message says "next course 009". After I have overflown YMNG, both DIST NEXT and ETE commence running UP and not resetting and then running down from YSHT. The only way to run down from YSHT is from Active Route page > menu> next route waypoint > enter. Is there no automatic way for this to happen?
