The P3 is made removable as a theft deterrent (I believe)..... Sorta like removable radio-face-plates.

This may be handy if you ever use long term storage (like remote airport parking lots) where you want to remove everything that could possibly attract a thief (to avoid getting a window smashed out).

I have never removed my controller other than when I bought our new truck (I moved it from one truck to the other).
