Just got my replacement display in, and it works fine.
The software version is now v.04o
I went through the setup and all the menus, and nothing has changed cosmetically. Though I noticed the reception might be better. With the antenna retracted, it shows four bars, whereas on the old unit, I'd get three bars even with the antenna up.
With getting my replacement within a week, I'm pretty satisfied with how Acurite handled this issue.
