Does anyone know if you can add a factory remote start to a 2005 Crewcab which already has the factory alarm???:confused:

GM is offering the remote start alarms in a few of there cars and I was wondering if it is compatible with the ones that dont have it.

I don't think so...Do a search as there are many ways to remote start the truck. I installed an Astrostart bought from Max Power who is a member here. The unit works flawlessly and has tons of more range than my factory remotes did.
