Trimble auto steer

[Garyhealylad]

Hello everyone. I'm curious on the Trimble auto steer?, .. someone told me the other day, that if my auto steer knocks out due to bad signal, usually trees or wind turbines will do it, that it should still go in it's a +b line due to a 20 min recording built into the system??,.. first I have heard of it?,.. I rang my gps man from the dealer ship and he said there is, but it's not a very dependable system,..
Anyone know anything about this or have it set up?,. Currently running a Massey Ferguson 7720, and also Massey ferguson 8735 on it..
Thanks for the feed back👍
