When I bought my 12 it has the standard Airpath Compass mounted on the dash between the Vee Brace. It didn’t work at all, stayed on a heading of 060 and never moved. I contributed it to more junk and something else I would gave to address. Bought a Verticle Card Compass and the same thing it stays between 060 and 090. The mounting screws and nuts are brass, all the instruments are mounted with brass. The Vee Brace dose t appear to be magnitec but something is causing a significant disruption. Anybody else have this issue and what is your recommendation.
