Does anyone know of a good automatic start kit for the GS? I've been told that if I do get one, then i would have to get my factory alarm uninstalled which in turn would kill the functionality of the master key's trunk/door/sunroof unlock feature. Is this true? Can I get an automatic starter as an add-on to the lexus factory system? Please help???? Its gettiong cold on the East coast and I want to be able to come to a warm GS in the morning
