I have a NAZA-M v1 and it has been updated to the frameware  4.02 (lastest frameware for naza v2) after a crash I connected the GPS pin to the main controler and connected that to the PC
but seems that there is no GPS connected, no GPS mode and no IOC &... ( that GPS needed alert)

I tried an other GPS module of NAZA v2 and it was the same.

but the controler works corectly in att.mode and I have 30min flight with that.
I have tried the preveuse frameware and re update the newest one again but any time the answer was the same.
also I tested the GPS modules with a naza v2 and they were OK.

now how can I fix it?

Since you've tried a good GPS module but still no GPS connected...I suppose the GPS port on the Main Controller is broken.
Maybe you need to contact the dealer.

I have found something strange
how did it happen?!
one of the connections is broken !!!!
it seems that is has burnt because there is some soot (blackness) in the NAZA's case near that

I re-connected it but it doesnt work
