GPS 3dr don't work

hi @rmackay9
by following the wiki
I connect a 3DR GPS module with a cable that came with the sensor (6 pin -5 pin)
then I try with a cable with 6 pin, I detect it on APM but I do not get data

I flash the Pxhawk with the firmware 3.5.5
I detected the GPS (GPS fix () = 1)
but the latitude and log data are always zero
and my position on the map is the default (I am in France now)


is it GPS that does not work?
Or is it another problem?

Did you see this page http://ardupilot.org/copter/docs/common-installing-3dr-ublox-gps-compass-module.html#common-installing-3dr-ublox-gps-compass-module?
What are the LEDs doing? One should be on permanently and one should blink if GPS is locked.
