2004 remote starter
there wasn't a factory remote starter available for 2004. I had a black widow remote starter installed in my 2005 Tahoe right after I bought it in 2005, and it still starts it right up from nearly a mile away. Not a job I would try myself though. If you don't know exactly what you are doing it can wind up costing more to fix something broken by mistake than to pay the professional. I know you will need a GM module to get around the security system and that you will really enjoy this feature.
