don't know why there was no GPS mode on the radio ?  Any clue ?
  

Which version of the Phantom do you have? Make sure if it's the basic RC or the advanced with the thumb wheel. Next you are in the Phantom mode in the assistance software. try the Naza mode and see if that doesn't give you the GPS indicator.

You have to be in NAZA mode for those switches to work.  Click on PHANTOM grey button at the top to switch to NAZA.

has tried to switch to Naza-M Mode, but something strange, see the lower left corner of iOSD screen at Naza-M Mode. Is it normal ?

Video was removed as the problem was solved, thanks a lot ! )

It won't lock into GPS mode because you don't have any satellites locked. upper right hand corner shows 0 sat. that's why it's bouncing back and forth from GPS to ATT to FS (fail safe)
