I have an ID.4 being built that I just threw in the protection and convenience package for because why now. My dealer just called me to say they have an identical build they’d sell me, but it doesn’t have the protection and convenience package. Further, he said they can’t add this because it is factory isntalled. Isn’t it just basically floor mats and a trunk liner? Why can’t they throw this in? Can I do it myself later? What am I missing?
