NF548 MYP in the bay area, no cargo cover. I was disappointed and asked service about ordering the parts for it, and they said "no, it is not retrofittable", despite showing them all the posts and proof of other service centers either offering to install via mobile service, or ship out for customers to do themselves.
I'm sure they have to say that since it's not technically officially offered by Tesla as a retrofit, but I put in the order for the parts via mobile app anyway and will see what happens.
