Yes, you can choose from the canned list of default wash names. However if you name your washes differently than the names in pre-recorded list then you get a "________" for the wash name. Only one of my three washes has a name that's in the list of recorded names, so I get the "_______" on my top and bottom end washes.
I don't really like it but just deal with it. If the the custom EEPROM is reasonably priced I might consider it.
It will only "say" something for the wash if you select one of the default names from the list. I assume you've entered custom text prompts for your wash packages?
