I have a phantom 2 with a binding issue. The multirotor crashed and fell upside down of course shattering the GPS antenna. This was the first reason I thought was the root of the binding to the transmitter issue. I put a new GPS module in it and of course it needs calibration but the transmitter wont bind for anything so that I can flip the switches and do a calibration. I start it hold the bind button then turn on the tx and hit the bind button again and nothing. Im guessing it is the receiver or the transmitter but I do not want to spend an arm and a leg to find out. Ive been working on it for about 2 weeks and I'm dyeing here, anything would help, thank you.
