I did see that one guy successfully installed sub zero in his non sub zero vehicle. However, I just had a mobile service guy out to my house to program a new key fob and was asking him if I installed all the parts, if it’s possible to have that activated. He replied “no it’s not that easy. You can just installed that and flip a switch in the software to turn it on” so now I’m second guessing myself and I don’t know if it’s something I should pursue. Anyone else have these thoughts? Has anyone else attempted this?
