Shane, tks for your quick response.... update:
We flew to Pittsburg today as mentioned this morning. We've got the Ifly power figured out so that it works. We have to jiggle the cord between the battery and the unit. We can deal with that ...most probably a bad cord or connector on the 720.
We tried the ilevel again...same problem. We go to the wifi and click on ilevel. It connects quickly but says "PRE".... We tried disconnecting from ilevel and rebooting...same thing, we show connected to wifi on the ilevel but the ilevel says "PRE". Is this what we want to happen?
Wow!!! sitting here in Pittsburgh while writing this response, we followed your directions and finally got the unit to connect by going to menu => about => connected devices => wifi => iLevil ADS-B. Apparently the default sets the ilevil to Levil AHRS. I am excited... that is a pretty tricky differentiation.... but now that I know, I'm good to go.
Thanks for the great service. Another problem solved.......We are flying home tomorrow so I'll be able to check it out. I can deal with the cord issue until I talk to your folks.
