So first off, I did a lot of searching on this subject, but all I could find is 'it doesn't exist anymore' on threads that are 5+ years old, I then hit Google, and couldn't turn anything up.
The reason I want to do this, is because my radio volume control doesn't work, and my roomate just recently purchased a RX8, and the radio he got Kenwood Xcelon DMX905s, along with a CANbus adapter and OBD2 port adapter, so he has android auto, as well as a 'gauge' panel on the radio to display coolant temp/IAT/etc etc. I really don't want to give up steering wheel volume control, but I will if I have to. Price is also not a concern, if I have to spend 2-300$ for the adapter, that's perfectly fine, I just can't seem to find one.
[Edit]: I found this but I'm not sure if it's the right one.
