Question on swapping Professional Radios

I have a 2007 335i with the L7 Sound System with no USB, just AUX. If I were to swap radios (literally just the headunit/radio controls) with one from a newer E90 (that had USB), will that allow me to gain USB controls without changing anything else in the car? If so, can it be from a car without L7? Any programming needed? Thanks in advance.

And on a side note, if that does work, does that also give me the "gong" sound as well?
