So now I am looking into several ideas for control:
1) Haptic Encoder
2) Space Navigator
3) CAR2PC CD Changer to Computer Adapter (Not available yet for Mazda unless you use the PIE to M-bus and then M-bus to USB Car2PC adapter)
3) CDRSkulls USB gamepad
Looks like this will go on the back burner since the only functioning idea is CDRSkulls at the moment.
