I know there are several post on this and I have read thru them, forgive me I am a little confused! I read that you could
A) put a togle switch in and completely shut it off.
B) I could go to the dealer and they could "flash" my computer with the 2009 "flash" and then the stock button would work on my 2007X
C) Do the sequence that I read on here (shift transfer case to 4 hi and turn stearing wheel excet,excet) Does this completely shut it off?

I like having it on on icy roads here in MN but I almost get stuck in deep snow as it almost kills my engine.

can anybody weigh in on this? I would like to do the dealer "flash"option but am unsure if it works.
Thanks in advance
