Can someone tell me for sure how to read the info on the TIS website? When i plug in my VIN and get the O/S number - the number that the radio button is on is my current version. If another one shows up - that means that it is newer?

 

yes, if a number comes up that doesnt match yours its an update. your number should be on there though, in one spot, then down from there should be all the updates.
