Chuck,
I noticed you have an iFly 720. With this unit, just boot the unit up, then follow the below sequence.
Setup -> Tools (Icon) -> Start Menu -> then touch Navigation.
This will allow the unit to boot to navigation. If you use a SkyRadar or Use Wi-Fi updating, I would recommend not taking this approach. You would have to boot up, then exit into the set up to get to the Wi-Fi. If you experience any abnormal behaviors, try reverting back to booting to the Basic Menu.
