The REVO-1 is a plug-in RF remote and antenna system with up to 1500 feet range. This system comes with the (2) 1-button transmitters, the antenna and antenna cable. IMPORTANT: This is not a full remote car starter. This is an add-on remote control kit that works with Fortin Stand-alone remote start systems that consist of an EVO-ALL or EVO-ONE module only and do not include a separate remote start module. If you have an EVO-ALL or EVO-ONE that was NOT purchased from MPC, you will need a FlashLink Updater to make this product work. EVO-ALL or EVO-ONE stand-alone systems purchased from MPC have the correct settings and the updater is not needed.
