Morning GMTC friends, as you may know I have an 07 NBS LS Silverado with keyless entry. I was informed that my truck already has the remote start option built into my truck and that all I need is the remote start remotes. Does anyone know of this being true and or who has done this? Would love to find out before I spend $$$ on an aftermarket remote start. If I have it factory I'd rather use it.
Thanks in advanced.

If I find out this is true before anyone responds I will post my results.
