Generally speaking, change the ending 5 to a 0.
that is true for the 880, but the number is different for a lot of the 748,768, 659....
but I would say that generally to go European change the last digit to 5 but to go NA look for the model with the two first digits that are the same.
PS the only one that does not follow that rule is the original Harmony that was renamed 745 when it got a model number (when the 768 and 748 came out)
