all of a sudden when I go to menu on my gn s2 and try and set engine volume all I get on the screen is "set engine sounds" and it goes back to menu. it also does this on the cab chatter volume. everything else sets fine. how do I clear this off. I tried an engine reset and a factory reset but no good for engine volume. now it is wide open and way too loud. thanks for any help.
