A friend of mine gave me his Phantom vision as it was no more use to him (the camera did not work anymore)
As a new (WIFI) camera is really expensive, and as I still had a DJI Naza M Lite Flight controller I opted for replacing the Phantoms NAZA with a true DJI Naza M Lite, and adding another camera to it.
The transfer was easy, but the DJI Naza M Lite did not recognize the Vision's GPS (and compass).
I replace the original GPS in the Vision with the one that came with the DJI Naza M Lite.
I also replaced the compass with the original one from the DJI Naza M Lite.
After changing some small settings in the "DJI NAZAM Lite Assistant" it worked except the LED's.
(note: The LED's are now replaced with the one in the DJI Naza M Lite LED unit. This unit is now also used to connect the USB)
I've also replaced the receiver in the Vision with a Graupner receiver, and this is also working fine with my Graupner MX12 HoTT
So basically I've now got a Vision working with a true DJI Naza M Lite on 2.4GHz.
I'm now adding a 5.8GHz video transmitter so that I can use my Fatshark goggles with it.
Unfortunately does a DJI Naza M Lite not work with the DJI iOSD (for telemetry), so I might change the DJI Naza M Lite later for a NAZA-M V2.
I'll be creating a thread about the project when all is done.
I hope that it's obvious that the DJI app will not work anymore with the above setup.
