Thanks AugustH. In my situation, above, The digital COG was correct. If the digital read out receives its information from the GPS if the HDG is disabled (COG enabled) does the ribbon receive the same GPS information? If so, how is it that the ribbon can be so far off the correct COG while the digital is correct? If not (the ribbon gets its information from the iPad compass), then you've explained a problem that can't be corrected unless the ribbon can receive information from the GPS.
