To be clear, you CAN NOT install a different sound set in any MRC decoder. Some do come with more than one sound set installed, allowing you to select which one of the installed ones you want to use. I could not find any documentation on the 1906 telling what sounds it has and whether or not it has more than one set, but if it does not already have the EMD 645 as one of it's options, then you can not program that sound set in it.
