I had to change the gps module on my mavic pro (1st model with sdcard onboard), I've bought a DJI genuine GPS module and mounted it, but when I try to fly I get this error "Navigation system error. Check redundancy state". Tried to recalibrate compass and IMU, and reflashed firmware again but it doesn't solved the problem... Is there a way to know if the gps module that I've bought is defective or am I missing something? Possible that I have to remove the onboard sdcard?
Thank you very much in advance
