on the top of the odo, there is a rod with rotating pins. these pins only rotate one direction and they lock the numbers in place.
using a pick tool pry up one end of the rod, left end. this will free up the numbers on that end. (i leave the other end of the rod in place and only lift it high enough to rotate the numbers on that end.) rotate the numbers to what you want. then snap the rod back in place. get the mileage within 1,000 miles and call it a day.
be sure the numbers, digits, are all positioned correctly. i think they can be off a bit and still locked in. and if it happens to be the 100k digit, you may have to wait a really long time for it to rotate and snap into the next correct position.
to the original poster, don't forget to convert km to miles and use that number on the ''new'' odo. ans of course the new number is going to be lower than the old one. this will likely pop a TMU (true miles unknown) title the next time it is registered.
