Not to my RV-12, but we purchased one about 3 years ago and tried it on our Cirrus SR-22. It didn't work very well. The unit could never maintain a stable attitude indication, even after they said they found a problem and corrected it. IIRC, altitude, heading, etc., worked OK, but the horizon was unusable. We were able to return it for a full refund (less shipping costs.)
Our Cirrus has a noticeable vibration and I suspect that resonated with BOM, but it's just a theory w/o any real data to support.
Have you looked at the mounting requirements?
