This post is primarily for Dynon. I have the HDX system and I love it. That being said I am not a big fan of Seattle Avionics... I am a Mac person, have been since 1984. I have used Seattle Avionics for two years, I had to purchase a used Microsoft Surface tablet for that use alone... When Airmate came along I was hoping that it would be the answer for us Mac users. I have read good results from some. When my subscription expired with SA I went to Airmate. The first month was uneventful, but I did notice the changes in the charts and lesser amount of georeferenced plates... not a huge deal. The second month was another story.. The app simply would not work... I contacted customer support and they knew of issues with the latest updates... They were helpful and it was resolved that I would have to do it either through my Surface tablet (why switch) and that ended up not working) or manually download and copy to a usb drive. This ending up taking hours 5 to 6.... My question to Dynon is why can't you partner with Jeppensen? I download updates for my Avidyne in a matter of minutes using either Mac or PC. It is quick and seamless... Is it more expensive, yes but maybe Dynon can secure a reasonable price for its clients.
