Hello,
Overall, the gps is great, but one thing I find a pain is to type and fly. I've used Bendix King 89 GPS systems before, and although not quite user friendly, enter an airport code is fairly easy: You spin the knob for the airport code and an intellisense feature shows possible matches for that code. Intellisense is essentially a recommendation for possible matches based on the 1st few letters of code.
For the iFly, It would be nice for the Direct To feature to implement an easy switching with the remote control:
1) The up/Down arrows would cycle through digits and numbers is sequence. 0-9A-Z..
2) The left/right arrows would cycle through the the position
Hope this makes sense, because I think a lot more functionality can be provide to the remote.
