ice-hot

I have a" 06" RX400H I bought it used a few years ago and it has been by far the best, most reliable car I have owned. I live in the Midwest (ND)and winters are very cold. The Lexus did not have remote start from the factory (maybe they never came from the factory with remote start) Did they? I don't know . If they did not, has anyone installed one or had one installed ? If so what brand remote start worked with the Hybrid system? Im a construction equipment mechanic and have installed many remote starters but can not find a brand that lists the 400H . Any and all info. will be greatly appreciated, don't want to go thru another winter getting into a cold car. Thank you, John
