As I am sure some of you Dynon Skyview users with antennas manufactured prior to 2012 have found out there will possibly be problem with your autopilot functioning properly.
This came to my attention a few weeks ago when making some approaches fully coupled and navigation being supplied from my Avidyne 440. From the FAF inbound the autopilot steered to the left and as I was VMC I just observed and it was off by two dots by the time I got to the MAP. I was able to duplicate the same behavior at two other airports. Enroute it worked just fine with no issues.
After consulting with Dynon I was informed that the GPS antennas manufactured prior to 2012 had a chip that was affected by the satellite date issue that took place in April. Dynon sent me a software patch and after loading it into the system all is well. Apparently the Skyview system uses its own antenna system for navigation as well that provided by the certified navigator and when there is a discrepancy strange things can happen without a warning prompt.
If you are flying IFR approaches with a Dynon antenna manufactured prior to 2012 you might get the patch before you have an issue and spend a bunch of time trying to figure out if you have a navigator or autopilot problem.
Also this same issue affected my D1 backup mini EFIS and I had to upgrade that antenna as well.
