F1 2017 Change strategy without Mic?

[Msportdan]

Hello guys

What input button is it to change strategy mid race. I have no mic and on a t300 gte. I have buttons for MFD, pit limiter etc etc. but cant seem to change strategy?

Cheers

You should press "right" on the steering cross like you confirm your change on the mfd.
