I had the DC3 added to my Nissan Altima, and I'm extremely happy. At first I was using the OEM remotes but with in a couple weeks I added the WG15 remotes to take advantage of the longer range of the remotes. I now will be upgrading to the T12 remote with the Drone mobile service, and also adding the KP2 combo pad. On my first car I had a Viper alarm and the remotes are way too fragile and the antenna was a headache to replace. So from now on I will be installing Compustar in all my future cars.
