Private Message me the VIN # and I'll run a factory specs sheet to see if it came with it. Yes, it can be installed if it does not currently have it, a dealer would be your best and safest bet, simply because other places aren't really certified to handle them. It could be costly... $150 - $350... but that depends.... so, let's start with the VIN and I'll see what you car came with from the factory.
