autochromatic assigning?

im try too use the autochromatic assign with my 2500 but it only says v-PITCH .it doesnt say AUTO does that have something to do with the os?? im using 1.21

i guess its the os im using,i was at sam ahs and i checked for the autochromatic assign on the mp they had on display and it wasnt there ,they had os 1.1 i think,then i was a gtc right across the street and theres was working and they had os 1.22 so i guess im using the old os but i had too many prob with 1.22 so i guess i wont beable to use th is feature
