I think many people (including myself) will be very happy with this app 
Because there wasnt an app for the MHI, i didnt buy the adapter.
i looked on the internet for WF-RAC adapters, but the one you said which isnt suitable is also called WF-RAC many times on the internet. Maybe you can be a more specific which model you need to have/buy which work with this app.
Thanks in advance!
