That would be too easy

Couldn't even get my NAV with a CD changer from the factory. OTOH, MBZ & BMW are very good in prewiring their NA-bound vehicles with a lot of the possible options. I remember I had a low-end 3 series years ago, the factory alarm & fogs were all prewired, literally plug-n-play, and it's the same thing on my daughter's C-class.
Prewiring the lights from the factory would have been a great idea, and certainly wouldn't break their bank in doing so. Besides, it would have alleviated lots of the sloppy wiring jobs done by the dealer & alike.
