Good questions, that I have seen asked before, in other models. First time I hae seen this considered specifically in an X7. As Auricom answers above, yes, ionization is separate from the scent part of the Ambient Air package. You are more than welcome to tackle your own DIY project, but what I'm recalling from other models is that trying to retrofit Ambient Air to a vehicle, after production, was unwieldy, not cost effective, and did not have provisions to readily allow this to be added, both hardware and software.

Certainly, if you do this project, let us know how it goes!
