If you run normal r/c, you will need to find every dcc address and kill it.
If you want “real-time”, and they don’t get it right at the dealer, you will need to reset it.
If your dealer is two states away, you really should learn how to do it yourself.
God help you if you don’t, if the system “glitches” and loses a setting (we won’t go there), or resets a dcc address all on it’s own (once again, we won’t go there), you will be quite happy to have the interface and program.
If you want to “fine-tune” the sound, you really should know how many setting there are.
However, if you are happy with something that simply makes noise out of the box, then go for it.
