2630 doesn't have all the guidance functions of the newer generations of displays. (4 and 5) 

You can have swap track available so the next track is ready to switch to. I haven't been around a 2630 lately though to remember the recording while on another line. 2630 can do active implement guidance, Gen4/5 can do active and passive implement guidance also for example. Just newer vs older tech 

You can do that in Gen4/5 monitors. But anymore most people are going away from doing curves on the end rows and just letting the display make a boundary track that gets them all the way around the field in one line for a pass or two or three and you can fill a straight while on it.
