Setting up G25 with GT5

[V8 Animal]

Started to play the game again after a 6 month break i want to use the handbrake with the button on the wheel.

Ive tried to reset the wheel in the calibration area with any wheel but can't get it to change.IIRC it was setup with DFP?

Any help on this please.

Thanks

I thought on the recent update the G25 was covered with button options?
