No it wouldn't, it's a 2 part update part 1 is downloading the updating from GM sever to USB, 2nd part after USB update is to reprogram the radio via sps, although I know most never do the 2nd part.
@JPbroad1970 has used the USB update I have for the 950 on his radio with no ill effects & didn't carry out the 2nd part.
