I will ask for that letter.@ChemEng when I picked up mine, my dealer gave me a letter to sign acknowledging that they will install the heated steering wheel once it's available. So yes they will / should install them free for you, too,since it's GM controlled not dealer by dealer.
Actually when I placed my order it said "no heated steering available" so I just assumed i would never get that feature. At least now I might some day get it...
Does anyone know what is involved in "installing a chip" later? I have never cracked open a module before, but i assume there arent plug and play chip sockets. Do they have some way of soldering or do they replace the whole board? I assume there are multiple functions per module so wont this just waste more "chips"?
I just can't picture how this process works....
