Seems when I was trying to explore functions the toggles didn't register right away(at least in my head) because I remember, well those don't work. And then I was in a race or something and trying to figure out how to bring up the MFD, because it really mattered. And then the toggles showed up somehow. Left one switches between the different multi function displays. Right one changes values.
I wouldn't hone in on the toggles being your only answer. We have different wheels other than them being Fanatec. If your wheel is working, left, right, gas, brake my guess is the MFD is in there somewhere. Keep searching/sorting out your wheel functions while on the road when it doesn't matter much. Keep us posted.
BTW: I'm on Firmware Version 2.08 Beta 12 now, same functionality.
