I am selling my old alarm system. Compustar 2w900 I believe is the model number. This was one of the best when I got it a few years ago, and is still an awesome system. Comes with both remotes, brain (which you can download new firmware on), temp. sensor, shock sensor, valet switch, all connections that come with it, antenna, and the RPS device. The 2 way remote has some scratches on it but it still works fine. I also have a full install manual to make life easy. It did come with starter kill relays pre wire but I cut them out, any one with half a brain can figure out how to put them back in just by looking at the manual. I had this in my car about a month ago but swapped it out for a Viper 5902. The whole system works excellent still. Asking $75 shipped.
