I received my SkyRadar this morning, and attemped to connect it to my iFly. No joy, the iFly said it saw a unknown device and asked for a device driver name to be entered, which of course is not possible on the iFly. I spoke with Ed at customer support who thought my Windows operating system might be in need of updating (I purchased my iFly Jan 2011) and is sending a SD card to do so by snail mail. For what it's worth, he also said that the GPS antenna that is supplied with the SkyRadar is not required when it is used with the iFly.
Any success stories out there?
