Put this together over the weekend and edited it today. I can only say categorically this worked for me with G29 into X1. It /says/ it should work with loads of combinations though. I should add, the first time I tried the G29/X1 combo turned out to be the only combo that didn’t work according to their firmware descriptions*. But since they updated firmware recently. it’s worked for me
*their amazon description simply listed wheels and then listed platforms. A bit sneaky imo, as I just assumed that they would all be compatible across that matrix as it were.
