Check to see if yours has the remote start accomodations package. If so it's rather simple to add. I do agree that the factory one isn't that great might be worth considering if you are setup for it. If you PM me your vin I can pull a BARS on it and tell you if it has it. Would be a nice break from all these freaking C4C deals I've been doing today. :crazy:Is it a major task to add a factory remote start to a 07 silverado?
