DJI introduce an new GPS, it sounds like the know the have issue's with the old (not 1 year old) one on the A2's.
me personal, think the have to replace it for the professional systems, this year the had so many problems and upgrades with the A2 GPS

let's see how the service for the experts are

I have the same question, I bought my A2 with my S900 in august, is this GPS Pro Plus going to be a warranty upgrade for the A2 or is it going to cost us to buy it?

i own 3 A2 systems with Z15 Gimbals and spreading wings copters :@
