Nope. It won't work. The hardware for business nav is completely different to professional nav. That's why you can only have OEM TV and voice recognition on pro nav. I believe business nav runs on the M-ASK (I've also seen it written as MAS-K and MASK) system, but pro nav runs on CCC (Car Communication Computer). The CCC is the only module that can display the map.
However, you can display video on the business nav screen using an external module. More details here: http://www.e90post.com/forums/showthread.php?t=9293
