I bought a second hand large idrive controller and fitted yesterday, the buttons worked but the rotation part didn't scoll?? I put small one back in. I have 2013 business nav. Anyone know if it's because it isn't compatible or is large controller faulty.
I have the same problem as this member.
Hope you'll help me.
Thanks
