I have a Phantom 2 V+ V3 that is about 2 months old. In the last couple weeks it has developed an erratic behavior, in the Assistance software it will no longer recognize the GPS module. After an advanced calibration it came back. This has happened several times. Doing the advanced calibration no longer works and I removed the GPS module. It is not cracked or visibly damaged. I've order a replacement module but at $160 I'm not happy about it. Has this happened to others? Is it common? No recent crashes and it still does this even with the cable firmly connected.
