2005 GP GTP would like to install factory remote start

I am looking to install a factory remote start on my car my remotes are going bad the buttons are not working properly. So i was thinking if there is a way to have a factory remote start set up on the car. I see some ebay sellers selling GM Remote Start Receiver Modules. Does anyone know if its possible to get that done and the cost ?

I dont see how you could install a factory remote start unless they all came prewired for it. My guess is they did not so you are out of luck.

from what i read all it requers is a GM Remote Start Receiver Modules. and then it can be programmed from tech II tool i wanted to see if anyone did this before.
