I have a wet compass with Audio Panel and Annunciator made for the C172SP in FSX/P3D.  However, it cannot be simply converted for MSFS because the Audio Panel on the MSFS C172, not only layouts but also programming codes, are different.

Thanks to a US friend Ross’s sponsorship, a new Wet Compass custom-made for the MSFS C172 has been developed accordingly.

The first video below shows the button operations for the Audio Panel, and the second video demonstrates the popping up of the Annunciator Panel when fuel is low and magneto is off.
