I know for a fact that the dealer can do it, I just had the computer chip replaced for my trans and then they had to reset all of my settings, so I had them set it to my liking, there where quite a few I could choose.. I dont remember what all they were. my dealer didn't charge me to do this, even when I went back a month later and had him change some programming... it took like 15 mins and I was off and on my way.... but as far as doing it yourself.... I am not sure.. I peaked thru the service window and watched them pop my hood and then they plugged my X up to some computer deal.. a few mins later, they pulled it out back and washed it then it was up front waiting for me.. they gave me the keys and that was that.. give the dealer a call, especially if there is a dealer that you have done business with in the past and it is easy for you to just stop by....
